Detailed Description
Referring to fig. 1 and 2, a first embodiment of a gear bidirectional clutch mechanism according to the present invention, which is used between a power output and a load, mainly includes a power source 10, a load 20, a clutch unit 30 and a deceleration unit 40; wherein the content of the first and second substances,
the power source 10 is used for power output, can transmit rotary power to the load 20 end through the clutch unit 30, and is provided with a power output shaft 101; wherein, the power source 10 can be a motor assembly;
the load 20 is connected to the clutch unit 30, can be driven by the rotary power output by the power source 10, and is provided with a load end rotating shaft 201;
the clutch unit 30 is connected between the power output shaft 101 of the power source 10 and the load end rotating shaft 201 of the load 20, and can transmit the rotating power of the power source 10 to the load 20, or can disconnect the power of the power source 10 from the load 20, and can make the load 20 rotate freely in idle, and is provided with a first output gear 301 and a buffer gear 302, wherein the first output gear 301 is installed on the power output shaft 101 of the power source 10, the first output gear 301 is provided with a tooth-missing part 3011 and a gear tooth part 3012, the buffer gear 302 is installed on the load end rotating shaft 201 of the load 20 and is connected with the first output gear, a through-going slot 3021 is arranged on the peripheral surface, so that the gear shaft center 3022 and the gear teeth 3023 form a non-rigid connection, and can generate relative torsional displacement when being stressed.
The gear teeth 3012 of the first output gear 301 and the gear teeth 3023 of the buffer gear 302 are set to have the same modulus so as to be capable of meshing with each other, and the number of teeth missing in the missing teeth 3011 of the first output gear 301 is not less than 2 teeth in the number of teeth missing in the missing teeth 3011 on the basis of avoiding meshing with the buffer gear 302.
As shown in fig. 3-6, the through-slots 3021 formed on the peripheral surface of the buffer gear 302 may be spiral slots (as shown in fig. 3 and 4) or annular slots (as shown in fig. 5) or may be arranged in a special-shaped manner to form multiple slots; the path of the slot 3021 may be defined according to different function curves; the width of the slot 3021 can limit the amount of relative torsional displacement between the gear axis 3022 and the gear teeth 3023; the slot 3021 defines the relative torsional elasticity of the gear axis 3022 and the gear teeth 3023 at the remaining boundary 3024 of the peripheral surface of the damper gear 302.
That is, according to the present invention configured as described above, as shown in fig. 7 and 8, when the power source 10 outputs the rotational power through the power output shaft 101, the first output gear 301 installed on the power output shaft 101 in the clutch unit 30 is driven to rotate, and since the first output gear 301 is provided with the tooth-lacking portion 3011 and the gear tooth portion 3012, when the first output gear 301 contacts the buffer gear 302 with the tooth-lacking portion 3011 in the rotation cycle of the power output shaft 101 (as shown in fig. 7), the buffer gear 302 will be in a non-meshing clutch state with the first output gear 301 and cannot be driven to transmit, and the clutch unit 30 will be in a non-clutching state, and then, the power source 10 causes the power output shaft 101 to continuously rotate, and the tooth-lacking portion 3011 of the first output gear 301 rotating along with the power output shaft 101 will be rotated to be out of the corresponding buffer gear 302, then, the gear tooth 3012 is engaged with the buffer gear 302 again (see fig. 8), so that the buffer gear 302 is driven to rotate and the load-end rotating shaft 201 is rotated together, and the clutch unit 30 can apply work to the load 20 again in the engaged state.
That is, according to the present invention constituted as above, when the power source 10 drives the first output gear 301 to rotate and the gear tooth portion 3012 is engaged with the buffer gear 302 to enter the engaged state, the clutch unit 30 outputs work to the load 20; when the power source 10 drives the first output gear 301 to rotate and the toothless part 3011 is tangent to the buffer gear 302 to enter a clutch state, the clutch unit 30 will be disconnected from the load 20, and the load 20 will be able to rotate freely.
In other words, when the present invention is applied to the operation of the automatic stove shutdown machine, please refer to fig. 9 and 10, when the load 20 (stove knob) rotates to the off state, the power source 10 (motor assembly) sets the tooth-lacking portion 3011 of the first output gear 301 of the clutch unit 30 to be tangent to the buffer gear 302 (see fig. 7), so that the buffer gear 302 and the first output gear 301 are in a clutch state of non-engagement, and the clutch unit 30 is in a clutch state of non-work; then, when the load 20 (stove knob) installed on the load end rotating shaft 201 is rotated to make the stove perform an ignition operation (as shown in fig. 9), since the buffer gear 302 of the clutch unit 30 and the first output gear 301 are in a non-meshed clutch state, the buffer gear 302 installed on the load end rotating shaft 201 will present a free rotation state of idle rotation, so that the load 20 (stove knob) can be easily rotated to perform a stove ignition operation; then, when the ignited stove is not turned off after a set time (for example, when the stove is forgotten to be turned off after soup or water is boiled), the power source 10 (motor assembly) is controlled to start and drives the first output gear 301 of the clutch unit 30 to rotate, and the tooth-missing portion 3011 of the rotating first output gear 301 is rotated to be disengaged from the corresponding buffer gear 302, and then the gear tooth portion 3012 is engaged with the buffer gear 302 again, so that the buffer gear 302 is driven to rotate in the opposite direction, and the load end rotating shaft 201 rotating together therewith can directly drive the load 20 (stove knob) to rotate in the opposite direction (as shown in fig. 10) to automatically turn off the stove, thereby achieving the effect of improving the safety of the stove.
As described above, in the present invention, when the clutch unit 30 enters the engaged state from the clutch state as shown in fig. 11, 12 and 13, and the first output gear 301 rotates to make the tooth-missing portion 3011 disengage from the corresponding buffer gear 302, and the gear tooth portion 3012 re-engages with the buffer gear 302 to make the clutch unit 30 return to work, in the process, usually, the probability of the first tooth 30121 of the gear tooth portion 3012 of the first output gear 301 generating the tooth-top interference with the buffer gear 302 is relatively increased, and the power source 10 (motor assembly) is easily locked up, and the mechanism is damaged, but since the buffer gear 302 of the present invention has the design of the cutting groove 3021 on the peripheral surface, the gear axis 3022 and the gear teeth 3023 form the non-rigid connection, and the relative torsional displacement phenomenon occurs when a force is applied, when the aforementioned tooth-top interference phenomenon occurs and the interference force exceeds the preset range, naturally, the damper gear 302 has torsional elasticity, so that the damper gear 302 will be twisted to eliminate the tooth top interference, so that the first tooth 30121 of the tooth portion 3012 of the first output gear 301 and the gear tooth 3023 of the damper gear 302 are guided to a correct meshing interval, thereby successfully avoiding the occurrence of stalling of the power source 10 (motor assembly), and achieving the effect of protecting the mechanism.
As described above, since the number of teeth missing in the teeth missing portion 3011 of the first output gear 301 according to the present invention is determined to avoid meshing with the buffer gear 302, the clutch operation between the first output gear 301 and the buffer gear 302 is extremely reliable, and the effect of ensuring the smoothness of the mechanism operation can be achieved.
As described above, the manner of transmitting the power of the power source 10 to the load 20 by the gear bidirectional clutch mechanism of the present invention is not limited to using the clutch unit 30 as a transmission chain, and the clutch unit 30 can be used as a basis to selectively connect the speed reduction unit 40 in series at the rear stage or/and the front stage of the clutch unit 30 to change the speed reduction ratio of the transmission chain, so as to achieve the effect of increasing or changing the output torque, however, the clutch unit 30 composed of the first output gear 301 with the tooth-lacking portion 3011 and the buffer gear 302 with the cutting groove 3021 is still a necessary component of the transmission chain of the present invention; that is to say that the first and second electrodes,
referring to fig. 14 and 15, another preferred embodiment for implementing the present invention is described, wherein a transmission chain connected between the power output shaft 101 of the power source 10 and the load-side rotating shaft 201 of the load 20 includes a clutch unit 30 composed of the first output gear 301 installed on the power output shaft 101 and having the tooth-missing portion 3011 design and the buffer gear 302 having the slot 3021 design and connected with the first output gear 301, a speed reduction unit 40 is connected to a rear section of the clutch unit 30, the speed reduction unit 40 is provided with at least two or more speed reduction gears (e.g. a first speed reduction gear 401, a second speed reduction gear 401', and a third speed reduction gear 401 "shown in fig. 14) engaged with each other to transmit power, wherein the speed reduction gear 401 (e.g. the first speed reduction gear 401) is fixed to a first fixed shaft 41 coaxially with the buffer gear 302 of the clutch unit 30, rotating synchronously with the buffer gear 302, wherein one reduction gear 401 "(e.g. the third reduction gear 401") is installed at the load side rotating shaft 201, and the power outputted from the power source 10 is transmitted to the load side rotating shaft 201 via the clutch unit 30 and the reduction unit 40 by engaging the other reduction gears 401 '(e.g. the second reduction gear 401') installed at the second fixed shaft 42 with each other, and rotating the load 20 together;
that is, when the transmission chain of the present invention constituted by the reduction unit 40 serially connected to the rear stage of the clutch unit 30 is applied to the operation of the automatic cooker-off machine, as shown in fig. 16, 17, 18 and 19, the power source 10 (motor assembly) sets the tooth-missing portion 3011 of the first output gear 301 of the clutch unit 30 to be in contact with the buffer gear 302 (see fig. 16 and 17) when the load 20 (cooker knob) is rotated to the off state, so that the buffer gear 302 and the first output gear 301 are in a non-engaged clutched state and the clutch unit 30 is in a non-operated clutched state, and then rotates the load 20 (cooker knob) mounted on the load end rotating shaft 201, so that the buffer gear 302 and the first output gear 301 of the clutch unit 30 are in a non-engaged clutched state (see fig. 16, 17), Fig. 17), the third reduction gear 401 ″ of the reduction unit 40 installed on the load side rotation shaft 201, the second reduction gear 401' and the first reduction gear 401 engaged with each other, and the buffer gear 302 coaxially fixed with the first reduction gear 401 will be in an idle free rotation state, so that the load 20 (oven knob) can be easily rotated to perform the oven ignition operation; then, when the ignited stove is not turned off after a set time (for example, when the stove is forgotten to be turned off after soup or water is boiled), the power source 10 (motor assembly) is controlled to start and drives the first output gear 301 of the clutch unit 30 to rotate, and the tooth-missing portion 3011 of the rotating first output gear 301 is rotated to disengage from the corresponding buffer gear 302 and then re-engaged with the buffer gear 302 by the gear tooth portion 3012 (as shown in fig. 18 and 19) to drive the buffer gear 302 to rotate in the opposite direction, meanwhile, the first reduction gear 401 of the reduction unit 40 coaxially fixed to the buffer gear 302 also drives the engaged second reduction gear 401' and the third reduction gear 401 "to rotate in the opposite direction along with the rotation of the buffer gear 302, and the load end rotating shaft 201 provided with the third reduction gear 401" also rotates in the opposite direction together, accordingly, the load 20 (stove knob) connected to the load end rotation shaft 201 can be directly driven to rotate reversely to automatically close the stove fire, thereby achieving the effect of improving the safety of the stove.
Referring to fig. 20, in a third embodiment of the present invention, after the first output gear 301 of the clutch unit 30 is installed on the power output shaft 101 of the power source 10 and connected to the buffer gear 302 to form a transmission chain, the rear section of the clutch unit 30 may also be connected to a reduction unit 40 formed by more reduction gears (e.g. a first reduction gear 401, a second reduction gear 401 ', a third reduction gear 401 ", and a fourth reduction gear 401"'), accordingly, by connecting the clutch unit 30 between the power source 10 and the load 20 and connecting the reduction unit 40 including a plurality of reduction gears to the rear section of the clutch unit 30, the transmission chain formed by the present invention can achieve the desired clutch effect and the effect of increasing or changing the reduction ratio according to the use requirement.
Referring to the fourth embodiment of the present invention shown in fig. 21 and the fifth embodiment of the present invention shown in fig. 22, in which a transmission chain connected between the power output shaft 101 of the power source 10 and the load end rotating shaft 201 of the load 20 can also connect the speed reducing unit 40 to the front section of the clutch unit 30, for example: the first reduction gear 401 of the reduction unit 40 is installed on the power take-off shaft 101 of the power source 10, the second reduction gear 401 ' of the reduction unit 40 is installed on the first stationary shaft 41, the first reduction gear 401 and the second reduction gear 401 ' are kept engaged, and the clutch unit 30 installed on the rear stage of the reduction unit 40 is such that the first output gear 301 provided with the toothless portion 3011 and any other reduction gear of the reduction unit 40 can be coaxially fixed (as shown in fig. 21, the first output gear 301 and the second reduction gear 401 ' can be coaxially fixed on the first stationary shaft 41), and the buffer gear 302 connected to the first output gear 301 and provided with the cutting groove 3021 can be installed on the load side rotating shaft 201 (as shown in fig. 21), or the buffer gear 302 can be installed on any other one of the power take-off shaft 101 and the load side rotating shaft 201 (as shown in fig. 22, the buffer gear 302 is installed on the second fixed shaft 42, and transmits power to the fourth reduction gear 401' "of the load end rotating shaft 201 through the third reduction gear 401" coaxially and fixedly installed, thereby, by using the clutch unit 30 connected between the power source 10 and the load 20 and the reduction unit 40 connected to the front section of the clutch unit 30, the transmission chain of the present invention formed by the mutual cooperation of the clutch unit 30 and the reduction unit 40 can achieve the expected clutch effect, purpose and the effect of increasing or changing the reduction ratio according to the use requirement.
As described above, since the clutch unit 30 and the speed reduction unit 40 are connected between the power source 10 and the load 20, the transmission chain can achieve the effect of clutch and increasing or changing the speed reduction ratio, when the power source 10 drives the first output gear 301 of the clutch unit 30 to rotate and the gear tooth portion 3012 of the first output gear 301 is stopped in a meshed state, the speed reduction unit 40 has a high speed reduction ratio, and naturally, the external rotating force at the load 20 end is difficult to be transmitted back to the power source 10, thereby achieving the purpose of self-locking. That is, when the present invention is applied to the operation of the automatic cooker-closing machine, when the load 20 (cooker knob) is rotated to the off state (as shown in fig. 17), the first output gear 301 of the clutch unit 30 is originally tangent to the buffer gear 302 by the toothless part 3011, so that the load 20 (cooker knob) can be freely rotated, but if necessary, the user can operate the power source 10 (motor assembly) to start up to rotate the first output gear 301, and stop the first output gear 301 immediately when the gear part 3012 is engaged with the buffer gear 302 (as shown in fig. 19), so that the rotational force applied to the load 20 (cooker knob) is hard to be transmitted back to the power source 10 (motor assembly) when the speed reduction unit 40 is in high reduction ratio, so that the load 20 (cooker knob) cannot be rotated arbitrarily, thereby preventing the child from rotating the cooker knob arbitrarily to perform the ignition operation, the effect of improving the use safety of the stove is achieved.
The timing of the power source 10 (motor assembly) to be controlled to start and stop can be controlled by a timer, various sensors (sensors) or a microswitch in the control circuit.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
