The utility model provides a clutch transmission mechanism 100.

In an embodiment of the present invention, please refer to fig. 1 to fig. 3 in combination, the clutch transmission mechanism 100 includes a driving shaft 110, an input rotation body 120, an output shaft 130, a first one-way bearing 150, an output rotation body 140, a second one-way bearing 160, a third one-way bearing 190 and a driven assembly 170; the input rotator 120 is mounted on the drive shaft 110; the first bearing connects the driving shaft 110 and the output shaft 130; the output rotator 140 is attached to the output shaft 130; the rotation direction of the second one-way bearing 160 is opposite to the rotation direction of the first one-way bearing 150; the second one-way bearing 160 is mounted on the output shaft 130 and is arranged between the output shaft 130 and the output rotator 140; the third one-way bearing 190 is mounted on the drive shaft 110 and is disposed between the drive shaft 110 and the input rotary body 120; the input revolving body 120 and the output revolving body 140 are in transmission connection through a driven assembly 170; the driving shaft 110 has a first rotating direction and a second rotating direction which are opposite to each other, and when the driving shaft 110 rotates along the first rotating direction, the driving shaft 110 drives the output shaft 130 to rotate at a first rotating speed through the first one-way bearing 150; when the driving shaft 110 rotates in the second rotation direction, the driving shaft 110 drives the output rotation body 140 to rotate through the driven assembly 170, and then the output rotation body 140 drives the output shaft 130 to rotate at the second rotation speed.

The rotation of the driving shaft 110 may be driven by a power source, which may be the motor 200, or a gear assembly connected to the motor 200, etc., or the driving shaft 110 may directly serve as the driving shaft 220 of the motor 200. It can be understood that the one-way bearing is a bearing that can rotate freely in one rotation direction and is locked in the other rotation direction, so that when the first one-way bearing 150 is connected between the driving shaft 110 and the output shaft 130, when the driving shaft 110 rotates in one direction, the first one-way bearing 150 can rotate freely, so as not to drive the output shaft 130 to rotate synchronously, and when the driving shaft 110 rotates in the other rotation direction, the first one-way bearing 150 is locked, so that the first one-way bearing 150 rotates synchronously with the driving shaft 110, and the output shaft 130 is further driven to rotate synchronously under the action of the first one-way bearing 150. For convenience of description, when the driving shaft 110 rotates in the forward direction (clockwise rotation, i.e., the first rotation direction mentioned above), the first one-way bearing 150 is locked to rotate synchronously with the driving shaft 110; when the driving shaft 110 rotates reversely (rotates counterclockwise), the first one-way bearing 150 rotates freely, so that the output shaft 130 does not rotate along with the driving shaft 110. The clutch speed-change mechanism 100 in the technical solution of the present invention further includes a second one-way bearing 160 and a third one-way bearing 190, where the rotation directions of the second one-way bearing 160 and the third one-way bearing 190 are opposite to the rotation direction of the first one-way bearing 150, which means that the driving rotation directions for driving the first one-way bearing 150 and the second one-way bearing 160 to freely rotate are opposite, and the driving rotation directions for driving the first one-way bearing 150 and the second one-way bearing 160 to freely rotate are also opposite; the driving rotation directions in which the first one-way bearing 150 and the third one-way bearing 190 can freely rotate are opposite to each other, and the driving rotation directions in which the first one-way bearing 150 and the third one-way bearing 190 can freely rotate are also opposite to each other. For example, when the first one-way bearing 150 is locked, the first one-way bearing 150 needs to be driven to rotate forward, and when the second one-way bearing 160 and the third one-way bearing 190 are locked, the second one-way bearing 160 and the third one-way bearing 190 need to be driven to rotate reversely; when the first one-way bearing 150 can rotate freely, the first one-way bearing 150 needs to be driven to rotate reversely, and when the second one-way bearing 160 and the third one-way bearing 190 can rotate freely, the second one-way bearing 160 and the third one-way bearing 190 need to be driven to rotate forwardly.

It can be understood that when the driving shaft 110 rotates in the forward direction (i.e. the first rotation direction mentioned above), it drives the output shaft 130 to rotate synchronously through the first one-way bearing 150, so that the output shaft 130 can output the same rotation speed as the driving shaft 110, and at this time, the output shaft 130 rotates at a high speed. Meanwhile, since the clutch transmission mechanism 100 according to the present invention further includes the second one-way bearing 160 and the third one-way bearing 190, the rotation direction of the second one-way bearing 160 and the rotation direction of the third one-way bearing 190 are both opposite to the rotation direction of the first one-way bearing 150, when the third one-way bearing 190 is disposed between the driving shaft 110 and the input rotator 120, the driving shaft 110 does not rotate in the forward direction by the third one-way bearing 190, and the input rotator 120 is not driven to rotate by the driving shaft 110. Similarly, when the driving shaft 110 rotates forward and directly drives the output shaft 130 to rotate forward, the output rotation body 140 will not be driven to rotate by the second one-way bearing 160, so as to ensure that the driving shaft 110 directly drives the output shaft 130 to rotate by the first one-way bearing 150, which has a stable transmission effect.

When the driving shaft 110 rotates reversely (i.e. the above-mentioned second rotation direction rotates), the driving shaft 110 can only drive the rotating ring connected with the driving shaft 110 in the first one-way bearing 150 to rotate freely, while the rotating ring connected with the output shaft 130 in the first one-way bearing 150 cannot rotate, so that the driving shaft 110 cannot directly drive the output shaft 130 to rotate synchronously when rotating reversely; however, when the third one-way bearing 190 is disposed between the driving shaft 110 and the input rotator 120, the second one-way bearing 160 is disposed between the output shaft 130 and the output rotator 140, and the rotation directions of the second one-way bearing 160 and the first one-way bearing 150 are opposite, the driving shaft 110 can sequentially transmit the torque to the input rotator 120, the driven assembly 170, and the output rotator 140 through the third one-way bearing 190, and transmit the torque to the output shaft 130 through the second one-way bearing 160, so as to drive the output shaft 130 to rotate at the second rotation speed. The arrangement of the driven assembly 170 enables the rotation speed of the output shaft 130 to be reduced, and further, the effect of low-speed rotation of the output shaft 130 can be achieved in the technical scheme of the utility model.

Under the condition that the driving shaft 110 rotates forwards and backwards, the effect of driving the output shaft 130 to rotate can be achieved, and meanwhile, the output shaft 130 has different output rotating speeds in different rotating directions of the driving shaft 110, so that the clutch speed change mechanism 100 in the technical scheme of the utility model can be suitable for different application scenes. The clutch transmission mechanism 100 of the present invention may be a part of an internal structure of a cooking appliance or other kinds of electric appliances, the driving shaft 110 and the output shaft 130 may be mounted on a housing of the cooking appliance or other kinds of electric appliances, and may be arranged reasonably with parts inside the cooking appliance or other kinds of electric appliances and formed as a whole, wherein the driving shaft 110 and the output shaft 130 may be mounted on different housing parts of the cooking appliance or other kinds of electric appliances, or may be mounted on a housing in the same area. In practical application, when the electric appliance is applied to an electric appliance, for example, a cooking appliance, the driving shaft 110 rotates forward and directly drives the output shaft 130 to rotate at a high speed (first rotating speed) through the first one-way bearing 150, so as to meet the requirement of fruit juice whipping, and when the driving shaft 110 rotates backward to drive the output shaft 130 to rotate sequentially through the input rotating body 120, the driven assembly 170 and the output rotating body 140, the driving shaft 130 rotates at a low speed and with a high torque, so as to meet the heavy-load operation scene such as dough making, and thus meet the use requirement of people on the diversification of the functions of the electric appliance.

According to the technical scheme of the utility model, the first one-way bearing 150 is connected between the driving shaft 110 and the output shaft 130, so that when the driving shaft 110 rotates in two opposite rotating directions, the output shaft 130 can be directly driven to rotate through the first one-way bearing 150, or the effect of disconnecting the output shaft 130 through the first one-way bearing 150 is achieved. By providing the second one-way bearing 160 opposite to the rotation direction of the first one-way bearing 150, and installing the second one-way bearing 160 between the input rotation body 120 and the driving shaft 110 or between the output rotation body 140 and the output shaft 130, the input rotation body 120 is in transmission coupling with the first transmission coupling ring 172 of the driven assembly 170, and the output rotation body 140 is in transmission coupling with the second transmission coupling ring 173 of the driven assembly 170, when the driving shaft 110 rotates in the first rotation direction, it directly drives the output shaft 130 to rotate at the first rotation speed through the first one-way bearing 150, and at the same time, the third one-way bearing 190 installed between the input rotation body 120 and the driving shaft 110 plays a role in disconnecting the transmission connection relationship between the driving shaft 110 and the input rotation body 120, and the second one-way bearing 160 installed between the output rotation body 140 and the output shaft 130 plays a role in disconnecting the transmission connection relationship between the output rotation body 130 and the output rotation body 140, further, the driving shaft 110 is prevented from transmitting power to the output shaft 130 through the input rotation body 120 and the driven assembly 170, and the output shaft 130 is prevented from being locked; meanwhile, the phenomenon that the output shaft 130 transmits power to the driving shaft 110 through the output revolving body 140 and the driven assembly 170 is avoided, and the phenomenon that the driving shaft 110 is blocked is avoided. When the driving shaft 110 rotates in the second rotation direction and cannot directly drive the output shaft 130 to rotate through the first one-way bearing 150, the second one-way bearing 160 installed between the input rotation body 120 and the driving shaft 110 plays a role in driving connection between the driving shaft 110 and the input rotation body 120 or driving connection between the output shaft 130 and the output rotation body 140, and further the driving shaft 110 can sequentially drive the output shaft 130 to rotate at the second rotation speed through the input rotation body 120, the driven assembly 170 and the output rotation body 140. Therefore, the technical scheme of the utility model can realize the effect of different transmission ratios by changing the rotation direction of the driving shaft 110.

Further, referring to fig. 1 or fig. 3, the driven assembly 170 includes a driven shaft 171, a first transmission coupling ring 172 and a second transmission coupling ring 173; the first transmission coupling ring 172 and the second transmission coupling ring 173 are coaxially disposed and are both mounted on the driven shaft 171, and the first transmission coupling ring 172 is in transmission coupling with the input rotator 120, and the second transmission coupling ring 173 is in transmission coupling with the output rotator 140.

With such an arrangement, the structure of the driven assembly 170 is relatively simple, and the input rotator 120 can still realize the effects of driving the output rotator 140 to rotate and shift gears through the driven assembly 170. The clutch speed-changing mechanism 100 in the technical scheme of the utility model can realize the effect of miniaturization on the basis of meeting the requirement of automatically changing the transmission ratio. Specifically, when the driving shaft 110 rotates reversely (i.e. rotates in the second rotation direction), the driving shaft 110 drives the input rotation body 120 to rotate reversely through the third one-way bearing 190, and since the input rotation body 120 is drivingly coupled to the first driving coupling ring 172, the input rotation body 120 drives the first driving coupling ring 172 to rotate normally when rotating reversely. In the present embodiment, the first transmission coupling ring 172 and the second transmission coupling ring 173 are coaxially disposed and are both mounted on the driven shaft 171, so that the second transmission coupling ring 173 rotates forward synchronously with the first transmission coupling ring 172, and since the second transmission coupling ring 173 is transmission-coupled with the output revolving body 140, the output revolving body 140 is driven to rotate backward when the second transmission coupling ring 173 rotates forward. The output rotator 140 and the output shaft 130 are connected by the second one-way bearing 160, and the second one-way bearing 160 and the third one-way bearing 190 rotate in the same direction, so that the output rotator 140 can drive the output shaft 130 to rotate in the reverse direction even when rotating in the reverse direction.

The driven assembly 170 includes a driven shaft 171, a first transmission coupling ring 172 and a second transmission coupling ring 173; the first transmission coupling ring 172 and the second transmission coupling ring 173 are coaxially disposed and both mounted on the driven shaft 171, and the first transmission coupling ring 172 is in transmission coupling with the input rotator 120, and the second transmission coupling ring 173 is in transmission coupling with the output rotator 140, in order to achieve the effect that the clutch transmission mechanism 100 can have different transmission ratios, the present invention can also be implemented by other embodiments, and the other embodiments are different from the above embodiments in that the second one-way bearing 160 and the third one-way bearing 190 do not exist at the same time, but only one of them is disposed. For example, in addition to the configuration in which the first one-way bearing 150 connects the drive shaft 110 and the output shaft 130, only the second one-way bearing 160 installed between the output shaft 130 and the output rotation body 140 may be further provided, and the rotation direction of the second one-way bearing 160 is opposite to the rotation direction of the first one-way bearing 150. Alternatively, in addition to the first one-way bearing 150 connecting the drive shaft 110 and the output shaft 130, only the third one-way bearing 190 installed between the drive shaft 110 and the input rotator 120 may be further provided, and the rotation direction of the third one-way bearing 160 is opposite to the rotation direction of the first one-way bearing 150. It can be understood that when the driving shaft 110 rotates in the forward direction (i.e. the first rotation direction mentioned above), it can still directly drive the output shaft 130 to rotate synchronously through the first one-way bearing 150, so that the output shaft 130 can output the same rotation speed as the driving shaft 110, and at this time, the output shaft 130 rotates at a high speed. Meanwhile, when the clutch transmission mechanism 100 further includes a third one-way bearing 190 (excluding the second one-way bearing 160), the rotation direction of the third one-way bearing 190 is opposite to that of the first one-way bearing 150, and when the third one-way bearing 190 is disposed between the driving shaft 110 and the input rotation body 120, the driving shaft 110 does not drive the input rotation body 120 to rotate through the third one-way bearing 190 in the forward rotation direction, but the output shaft 130 drives the output rotation body 140 to rotate in the forward direction synchronously when rotating at a high speed, the output rotation body 140 rotates in the reverse direction through a second transmission coupling ring 173 in the driven component 170, because the second transmission coupling ring 173 is disposed coaxially with the first transmission coupling ring 172, the first transmission coupling ring 172 is in transmission coupling with the input rotation body 120 on the driving shaft 110, and therefore the second transmission coupling ring 173 rotates in the reverse direction to drive the first transmission coupling ring 172 to rotate in the reverse direction and the input rotation body 120 to rotate in the forward direction; however, since the third one-way bearing 190 and the first one-way bearing 150 rotate in opposite directions, the driving shaft 110 is not driven to rotate again by the third one-way bearing 190 when the input rotation body 120 rotates in the forward direction, and the input rotation body 120 driven by the first transmission coupling ring 172 is in an idle rotation state relative to the driving shaft 110 during the rotation process, so that the situation that the driving shaft 110 is driven to rotate at different rotating speeds through the input rotation body 120 and other power sources at the same time to cause the driving shaft 110 to generate jamming interference can be avoided.

When the clutch transmission mechanism 100 further includes a second one-way bearing 160 (excluding the third one-way bearing 190), the second one-way bearing 160 is disposed between the output shaft 130 and the output rotation body 140, in this scheme, the driving shaft 110 rotates forward to drive the input rotation body 120 to rotate forward synchronously, and then the input rotation body 120 is coupled in a transmission manner through the first transmission coupling ring 172 of the driven component 170 to drive the first transmission coupling ring 172 to rotate backward, because the second transmission coupling ring 173 is disposed coaxially with the first transmission coupling ring 172 and is coupled in a transmission manner with the output rotation body 140, the first transmission coupling ring 172 rotates backward to drive the second transmission coupling ring 173 to rotate backward and the output rotation body 140 rotates forward; however, the second one-way bearing 160 is disposed between the output shaft 130 and the output rotator 140, so that the one-way bearing is allowed to rotate freely when the output rotator 140 rotates forward, that is, the output rotator 140 rotates idly on the output shaft 130, and at this time, the output rotator 140 does not drive the output shaft 130 to rotate, thereby avoiding the occurrence of the jamming caused by the output rotator 140 and the driving shaft 110 driving the output shaft 130 to rotate simultaneously.

Further, referring to fig. 1, fig. 3, fig. 4 and fig. 5 in combination, based on the scheme that the second one-way bearing 160 is installed between the output shaft 130 and the output rotator 140, and the third one-way bearing 190 is not arranged between the driving shaft 110 and the input rotator 120, the driving shaft 110 includes a first installation part 111 and a second installation part 112 connected with each other, the first one-way bearing 150 is installed on the first installation part 111, the input rotator 120 is installed on the second installation part 112, the second installation part 112 is non-cylindrical, the input rotator 120 has a first installation hole 121 for installing on the second installation part 112, and the shape and size of the first installation hole 121 are adapted to the shape and size of the second installation part 112. Thus, when the driving shaft 110 rotates, it can drive the input rotator 120 to rotate synchronously through the second mounting portion 112. Further, by providing the second mounting portion 112 in a non-cylindrical shape, the mounting structure of the second mounting portion 112 and the input rotator 120 is simplified, and the second mounting portion 112 and the input rotator 120 can be prevented from being connected by a joint.

Of course, in order to achieve the effect of synchronous rotation of the driving shaft 110 and the input rotation body 120, the driving shaft 110 may be cylindrical, and the driving shaft 110 and the input rotation body 120 may be keyed to achieve the effect of synchronous rotation. It should be noted that the key connection method is common knowledge of those skilled in the art, and will not be described in detail herein.

When the third one-way bearing 190 is installed between the driving shaft 110 and the input rotator 120 and the second one-way bearing 160 is not provided between the output shaft 130 and the output rotator 140, the output shaft 130 may include a third installation portion and a fourth installation portion connected to each other, the first one-way bearing 150 is connected to the third installation portion, the output rotator 140 is installed to the fourth installation portion, the fourth installation portion is non-cylindrical, the output rotator 140 has a second installation hole 141 for installation to the fourth installation portion, and the shape and size of the second installation hole 141 are adapted to the shape and size of the fourth installation portion. So set up, when making the output shaft 130 rotate, it can drive the output revolving body 140 to rotate synchronously through the fourth installation part; or when the output rotation body 140 rotates, it can drive the fourth installation portion and further drive the output shaft 130 to rotate synchronously. Further, by providing the fourth attachment portion in a non-cylindrical shape, the attachment structure of the fourth attachment portion and the input rotator 120 is simplified, and the fourth attachment portion and the input rotator 120 can be prevented from being connected by a joint.

Of course, as shown in fig. 7, in order to achieve the effect of synchronous rotation of the output shaft 130 and the output rotator 140, the output shaft 130 may have a cylindrical shape, and the output shaft 130 and the output rotator 140 may be keyed to achieve the effect of synchronous rotation. It should be noted that the key connection method is common knowledge of those skilled in the art, and will not be described in detail herein.

Further, based on the scheme that the third one-way bearing 190 is arranged between the driving shaft 110 and the input revolving body 120, and the second one-way bearing 160 is arranged between the output shaft 130 and the output revolving body 140, the driving shaft 110 and the output shaft 130 can be both cylinders, so that the driving shaft 110 and the output shaft 130 can be conveniently processed, the driving shaft 110 can be mounted on the second one-way bearing 160, and the output shaft 130 can be mounted on the third one-way bearing 190.

Further, referring to fig. 1 or 3, the driven shaft 171 is disposed parallel to the driving shaft 110.

It can be understood that the driving shaft 110 is connected to the output shaft 130 through the first one-way bearing 150, and the driving shaft 110 is disposed parallel to and coaxially with the output shaft 130. In this embodiment, the driven shaft 171 is disposed parallel to the driving shaft 110, so that the input rotation body 120 can transmit the power to the output rotation body 140 only by the two-stage transmission, and the effect of transmitting the power to the output rotation body 140 by the input rotation body 120 through an excessive number of followers is avoided.

Specifically, as shown in fig. 2, the input rotator 120, the first transmission coupling ring 172, the second transmission coupling ring 173, and the output rotator 140 are spur gears.

By providing the input rotation body 120, the first transmission coupling ring 172, the second transmission coupling ring 173, and the output rotation body 140 as spur gears, the transmission process of the entire clutch transmission mechanism 100 is made more stable.

Of course, in other embodiments, the input rotator 120 and the first drive coupling ring 172 can be friction wheels that are drive coupled to each other; or the second transmission coupling ring 173 and the output revolving body 140 can also be friction wheels which are mutually transmission-coupled; alternatively, the input rotor 120, the first transmission coupling ring 172, the second transmission coupling ring 173, and the output rotor 140 are all friction wheels. By such an arrangement, the selection of the components in the clutch transmission mechanism 100 is simple.

Further, referring to fig. 1, 3 and 4, one of the driving shaft 110 and the output shaft 130 is formed with a mounting groove 111a, and the first one-way bearing 150 is mounted in the mounting groove 111a and sleeved on the other of the driving shaft 110 and the output shaft 130.

So set up, then make first one-way bearing 150 can have comparatively stable installation effect, reduce first one-way bearing 150 and play in the axial of driving shaft 110 or output shaft 130, and then guarantee that driving shaft 110 can drive output shaft 130 synchronous rotation through first one-way bearing 150 when rotating along first direction of rotation steadily. Specifically, one end of the driving shaft 110 facing the output shaft 130 may be formed with a mounting groove 111a, the first one-way bearing 150 is mounted in the mounting groove 111a, the output shaft 130 penetrates the first one-way bearing 150, at this time, the driving shaft 110 is connected with an outer ring of the first one-way bearing 150, and the output shaft 130 is connected with an inner ring of the first one-way bearing 150. Or an installation groove 111a is formed at one end of the output shaft 130 facing the driving shaft 110, the first one-way bearing 150 is installed in the installation groove 111a, the driving shaft 110 penetrates through the first one-way bearing 150, at this time, the driving shaft 110 is connected with an inner ring of the first one-way bearing 150, and the driving shaft 110 is connected with an inner ring of the first one-way bearing 150.

The second one-way bearing 160 and the third one-way bearing 190 each have an inner ring, an outer ring, and a needle roller or a ball disposed between the inner ring and the outer ring. In this embodiment, referring to fig. 1 or fig. 3, a second one-way bearing 160 is further installed between the output shaft 130 and the output rotator 140, so that the output shaft 130 is matched with an inner ring of the second one-way bearing 160, and the output rotator 140 is matched with an outer ring of the second one-way bearing 160. Since the second one-way bearing 160 and the first one-way bearing 150 rotate in opposite directions, in order to enable the output shaft 130 to rotate in the second rotation direction, the second one-way bearing 160 is driven to rotate, or in order to enable the second one-way bearing 160 to rotate in the second rotation direction, the output shaft 130 in this embodiment is cylindrical.

Similarly, if the first one-way bearing 150 is connected between the drive shaft 110 and the output shaft 130, at least the portion of the drive shaft 110 connected to the first one-way bearing 150 is also cylindrical. Specifically, the mounting groove 111a is cylindrical based on the configuration in which the driving shaft 110 is formed with the mounting groove 111 a.

Further, referring to fig. 1, fig. 3 and fig. 4, at least two first engaging grooves 112a are formed in the driving shaft 110, a first engaging spring 181 is installed in each first engaging groove 112a, and the input rotator 120 is disposed between two adjacent first engaging springs 181.

In addition, by installing the second snap spring 182 in the second slot 131, the second snap spring 182 can be installed first in the installation process, and then the output rotator 140 can be installed; the output rotator 140 may be installed first, and then the second snap spring 182 is installed, so that the output rotator 140 and the second snap spring 182 are less constrained by the installation sequence in the installation process.

By providing the transmission case 101, the input rotary body 120, the output rotary body 140, the first one-way bearing 150, the second one-way bearing 160, and the driven component 170 of the clutch transmission mechanism 100 are mounted in the transmission case 101, so that the transmission case 101 can have a good protection effect on the clutch transmission mechanism 100, and can prevent a great amount of dust from falling into the clutch transmission mechanism 100 to affect the use effect thereof. In addition, by extending the output shaft 130 and the drive shaft 110 out of the transmission housing 101, the drive shaft 110 is facilitated to be connected to the power source and the output shaft 130 is facilitated to be connected to the actuator.

Specifically, as shown in fig. 1 or fig. 3, the transmission case 101 includes a first case cover 1011 and a second case cover 1012, the first case cover 1011 and the second case cover 1012 are detachably connected and jointly enclose a cavity for mounting the input rotary body 120, the output rotary body 140, the first one-way bearing 150, the second one-way bearing 160 and the driven assembly 170 of the clutch transmission mechanism 100, the driving shaft 110 extends out of the first case cover 1011, and the output shaft 130 extends out of the second case cover 1012.

The first cover 1011 and the second cover 1012 are detachably connected, and the first cover 1011 and the second cover 1012 together enclose a cavity in which the input rotary body 120, the output rotary body 140, the first one-way bearing 150, the second one-way bearing 160, and the driven assembly 170 of the clutch transmission mechanism 100 are mounted, so that the clutch transmission mechanism 100 can be conveniently mounted and dismounted. By extending the driving shaft 110 out of the first cover 1011 and the output shaft 130 out of the second cover 1012, the driving shaft 110 extending out of the first cover 1011 can be connected to a power source, and the output shaft 130 extending out of the second cover 1012 can be connected to an actuator.

Based on the scheme of the transmission case 101, in the present embodiment, please refer to fig. 1, fig. 3, fig. 8 and fig. 9 in combination, the transmission case 101 is provided with a first bearing hole, a first bidirectional bearing 102 is installed in the first bearing hole, and the first bidirectional bearing 102 is sleeved outside the driving shaft 110.

By the arrangement, the first bidirectional bearing 102 has a good supporting effect on the driving shaft 110, and the arrangement of the first bidirectional bearing 102 can reduce the friction force applied to the driving shaft 110 during rotation, so that the driving shaft 110 can be guaranteed to have a good power transmission effect in a long time. Further, the first bearing hole is opened in the first cover 1011 based on the configuration that the transmission case 101 has the first cover 1011 and the second cover 1012 and the drive shaft 110 is extended out of the first cover 1011.

In addition, the transmission case 101 is provided with a second bearing hole, a second bidirectional bearing 103 is installed in the second bearing hole, and the second bidirectional bearing 103 is sleeved outside the output shaft 130. So set up, then make second bidirectional bearing 103 have better supporting effect to output shaft 130 to the setting of second bidirectional bearing 103 can reduce the frictional force that receives when output shaft 130 rotates, and then can guarantee that output shaft 130 can all have better transmission power's effect in a longer time. Further, the second bearing hole is opened in the second cover 1012 based on the fact that the transmission case 101 has the first cover 1011 and the second cover 1012 and the output shaft 130 extends out of the second cover 1012.

The transmission case 101 may further have a third bearing hole, a third bidirectional bearing 104 is installed in the third bearing hole, and the third bidirectional bearing 104 is sleeved outside the driven shaft 171. By such arrangement, the third bidirectional bearing 104 has a better supporting effect on the output shaft 130, and the third bidirectional bearing 104 can reduce the friction force applied when the output shaft 130 rotates, so that the driven shaft 171 can have a better power transmission effect in a longer time. Further, based on the above-mentioned arrangement of the first cover 1011 and the second cover 1012 in the transmission case 101, third bearing holes may be opened on both the first cover 1011 and the second cover 1012.

The present invention further provides a motor 200, as shown in fig. 11, the motor 200 includes a motor body 210 and a clutch transmission mechanism 100, the specific structure of the clutch transmission mechanism 100 refers to the above embodiments, and since the motor 200 adopts all technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved, and no further description is provided herein. The motor body 210 and the clutch transmission mechanism 100 can be fixed together by a housing, the motor body 210 is an existing motor 200 structure, the motor body 210 includes a stator and a rotor structure, the rotor has a driving shaft 220, the driving shaft 220 is in transmission connection with the driving shaft 110, and the output shaft 130 is used for driving external components.

The present invention further provides a food processor, please refer to fig. 1, fig. 10 and fig. 11 in combination, the food processor includes a housing and a processing cup assembly 30, a motor 200 and a clutch speed-change mechanism 100 are disposed in the housing, the clutch speed-change mechanism 100 includes a driving shaft 110, an input revolving body 120, an output shaft 130, a first one-way bearing 150, an output revolving body 140, a second one-way bearing 160 and a driven assembly 170; the motor 200 is connected with the driving shaft 110 to drive the driving shaft 110 to rotate, and the input revolving body 120 is installed on the driving shaft 110; the first bearing connects the driving shaft 110 and the output shaft 130; the output rotator 140 is attached to the output shaft 130; the rotation direction of the second one-way bearing 160 is opposite to the rotation direction of the first one-way bearing 150; the second one-way bearing 160 is mounted on the output shaft 130 and is arranged between the output shaft 130 and the output rotator 140; alternatively, the second one-way bearing 160 is mounted on the drive shaft 110 and provided between the drive shaft 110 and the input rotator 120; the input revolving body 120 is in transmission coupling with the output revolving body 140 through the driven assembly 170, and has the same rotating direction as the output revolving body 140; the processing cup assembly 30 comprises a cup body 31, a stirring shaft 32 arranged on the cup body 31 and at least two different stirring pieces 33, wherein the stirring pieces 33 are detachably connected with the stirring shaft 32, the cup body 31 is arranged on a machine shell, and the stirring shaft 32 is in transmission coupling with an output shaft 130; when the motor 200 drives the driving shaft 110 to rotate in a first rotating direction, the driving shaft 110 drives the output shaft 130 to rotate at a first rotating speed through the first one-way bearing 150; when the motor 200 drives the driving shaft 110 to rotate along the second rotation direction, the driving shaft 110 drives the output rotation body 140 to rotate through the driven assembly 170, and then the output rotation body 140 drives the output shaft 130 to rotate at the second rotation speed; different stirring members 33 are selectively mounted to the stirring shaft 32 while the output shaft 130 rotates at the first rotation speed and rotates at the second rotation speed.

The rotation of the driving shaft 110 may be driven by a motor 200, the motor 200 may have a driving shaft 220, and the driving shaft 110 may be connected to the driving shaft 220 of the motor 200 by a coupling or a gear assembly, or the driving shaft 110 may directly serve as the driving shaft 220 of the motor 200. It can be understood that the one-way bearing is a bearing that can rotate freely in one rotation direction and is locked in the other rotation direction, so that when the first one-way bearing 150 is connected between the driving shaft 110 and the output shaft 130, when the driving shaft 110 rotates in one direction under the driving of the motor 200, the first one-way bearing 150 can rotate freely, so as not to drive the output shaft 130 to rotate synchronously, and when the driving shaft 110 rotates in the other rotation direction under the driving of the motor 200, the first one-way bearing 150 is locked, so that the first one-way bearing 150 rotates synchronously with the driving shaft 110, and the output shaft 130 is further driven to rotate synchronously under the action of the first one-way bearing 150. For convenience of description, when the driving shaft 110 rotates in the forward direction (clockwise rotation, i.e., the first rotation direction mentioned above), the first one-way bearing 150 is locked to rotate synchronously with the driving shaft 110; when the driving shaft 110 rotates reversely (rotates counterclockwise), the first one-way bearing 150 rotates freely, so that the output shaft 130 does not rotate along with the driving shaft 110. The clutch transmission mechanism 100 according to the present invention further includes a second one-way bearing 160, and the rotation direction of the second one-way bearing 160 is opposite to the rotation direction of the first one-way bearing 150, which means that the driving rotation directions for driving the first one-way bearing 150 and the second one-way bearing 160 to rotate freely are opposite, and the driving rotation directions for driving the first one-way bearing 150 and the second one-way bearing 160 to rotate freely are also opposite. For example, when the first one-way bearing 150 is locked, the first one-way bearing 150 needs to be driven to rotate forward, and when the second one-way bearing 160 is locked, the second one-way bearing 160 needs to be driven to rotate backward; when the first one-way bearing 150 is able to rotate freely, the first one-way bearing 150 needs to be driven to rotate reversely, and when the second one-way bearing 160 is able to rotate freely, the second one-way bearing 160 needs to be driven to rotate forwardly.

It can be understood that when the driving shaft 110 rotates in the forward direction (i.e. the first rotation direction mentioned above) under the driving of the motor 200, it drives the output shaft 130 to rotate synchronously through the first one-way bearing 150, so that the output shaft 130 can output the same rotation speed as the driving shaft 110, and at this time, the output shaft 130 operates at a high speed. Meanwhile, because the clutch speed-change mechanism 100 in the technical scheme of the present invention further includes the second one-way bearing 160, the rotation direction of the second one-way bearing 160 is opposite to that of the first one-way bearing 150, when the second one-way bearing 160 is disposed between the driving shaft 110 and the input revolving body 120, the driving shaft 110 does not drive the input revolving body 120 to rotate through the second one-way bearing 160 in the forward rotation direction, and the output shaft 130 drives the output revolving body 140 to synchronously rotate in the forward direction when rotating at a high speed, and the output revolving body 140 is in transmission coupling with the input revolving body 120 through the driven component 170, so the driven component 170 drives the input revolving body 120 to rotate in the forward direction; however, since the second one-way bearing 160 is disposed between the driving shaft 110 and the input rotator 120, and the rotation direction of the second one-way bearing 160 is opposite to the rotation direction of the first one-way bearing 150, the driving shaft 110 cannot be driven by the second one-way bearing 160 to rotate again when the input rotator 120 rotates, and the input rotator 120 is in an idle rotation state relative to the driving shaft 110 during the rotation process, so that the situation that the driving shaft 110 is driven to rotate at different rotation speeds by the input rotator 120 and the motor 200 at the same time to cause the jamming interference of the driving shaft 110 can be avoided. In the technical scheme of the present invention, the second one-way bearing 160 may also be disposed between the output shaft 130 and the output revolving body 140, in this scheme, the driving shaft 110, when rotating in the forward direction, drives the input revolving body 120 to rotate in the forward direction synchronously, and further the input revolving body 120 is in transmission coupling with the output revolving body 140 through the driven component 170, so that the driven component 170 drives the output revolving body 140 to rotate in the forward direction; however, the second one-way bearing 160 is disposed between the output shaft 130 and the output rotator 140, so that the one-way bearing is allowed to rotate freely when the output rotator 140 rotates forward, that is, the output rotator 140 rotates idly on the output shaft 130, and at this time, the output rotator 140 does not drive the output shaft 130 to rotate, thereby avoiding the occurrence of the jamming caused by the output rotator 140 and the driving shaft 110 driving the output shaft 130 to rotate simultaneously.

When the motor 200 drives the driving shaft 110 to rotate reversely (i.e. the above-mentioned second rotation direction rotates), the driving shaft 110 can only drive the rotating ring connected with the driving shaft 110 in the first one-way bearing 150 to rotate freely, while the rotating ring connected with the output shaft 130 in the first one-way bearing 150 cannot rotate, so that the driving shaft 110 cannot directly drive the output shaft 130 to rotate synchronously when rotating reversely; however, since the driving shaft 110 is connected to the output shaft 130 through the driven assembly 170, the second one-way bearing 160 is disposed between the driving shaft 110 and the input rotator 120 or the second one-way bearing 160 is disposed between the output shaft 130 and the output rotator 140, and the rotation directions of the second one-way bearing 160 and the first one-way bearing 150 are opposite, the driving shaft 110 can sequentially transmit the torque to the input rotator 120, the driven assembly 170, the output rotator 140 and the output shaft 130, and further can drive the output shaft 130 to rotate at the second rotation speed.
