Description

RINGLESS PLANET MAGNETIC GEAR CHANGING SYSTEM
Field of the Invention
The present invention relates to a ringless planet gear changing system.
Background of the Invention
A speed changer is a mechanism used for changing the rotating speed and torque from an input end, which can change the transmission ratio of an output shaft to an input shaft. The traditional speed changer generally employs gear transmission, and has certain deficiencies. On the one hand, common gear transmissions will generate vibration, noise, wear and heat phenomena due to their transmission characteristics, while dust, powder and the like will affect the lubrication performance. On the other hand, the common gear transmissions have certain deficiencies in terms of load carrying capacity, output torque, output efficiency, reliability, etc. The design objective of the present invention is to improve these defects of the speed changer.
A planet gear is widely applied to aspects of improving load carrying capacity, output torque and output efficiency. Compared with common gear sets, the planet gears have some outstanding advantages, for example, compact structure, small volume, high loading bearing capacity, high transmission efficiency, etc., and can achieve movement with large transmission ratio. By using these advantages, using the planet gears to replace common gears can effectively improve the performance of a speed changing box. The planet gear usually adopts the 2K-H planet transmission technology, and is most typically composed of several structures including sun gears, planet gears, gear rings, planet carriers, etc. In such a structure, the gear ring is an internal gear, which functions to be meshed with the internal gear. However, the error of the gear ring is an important factor causing the error of the planet gear. In order to ensure the accuracy of operation of the planet gear, it is usually required that the internal gear has higher machining precision, which increases the difficulty of production and machining.
The magnetic gear is a new gear technology. As shown in FIG. 1, a drive gear and a load gear are moved by the opposite attraction principle of magnets. No mechanical contact occurs between the magnetic gears, thus reducing the vibration and noise of a transmission mechanism. The magnetic gear transmits the movement and power to a closed space through the magnetic field of the magnetic material, which increases the flexibility of the design. The magnetic gear does not need to consider the contact friction, and does not require lubrication, thus not only being clean and environment-friendly but also saving, energy and reducing maintenance costs. The magnetic gear is not damaged when overloaded, and has an overload self-protection function. The permanent magnet surface does not require fine machining, and reduces the requirements for the production process. No obvious impact is generated in the moving process.
Summary of the Invention
In order to overcome the deficiencies of the mechanical gear speed changer, the present invention provides a design solution of a ringless planet gear changing system design, which is of great significance for the development of planet gears and magnetic gears and the development of speed control system.
In order to achieve the above objectives, the present invention adopts the following technical solution:
A ringless planet magnetic gear changing system, including an input shaft on which an input end planet carrier and a plurality of sun magnetic gears are mounted, wherein each sun magnetic gear is meshed with a plurality of planet magnetic gears to form a group, centers of a plurality of planet magnetic gears in different groups and in the same direction are connected to the same planet gear rotating shaft I on the same straight line, the planet gear rotating shaft I is connected to an output end planet carrier, the input end planet carrier is connected to a planet gear rotating shaft II, the planet gear rotating shaft II is eccentrically connected to the plurality of planet magnetic gears in different groups and in the same direction, and the connections of the plurality of sun magnetic gears and the input shaft are controlled by the synchronizer and the shift lever, thereby achieving output at different speeds.
Further, different groups of sun magnetic gears and planet magnetic gears form different transmission ratios.
Further, one end of the input shaft is mounted on a frame by a bearing, and the other end of the input shaft is mounted on the output end planet carrier by a bearing.
Further, an output shaft end of the output end planet carrier is also mounted on the frame by a bearing.
Further, two synchronizers and one shift lever located between the two synchronizers are mounted between every two sun magnetic gears, and the two synchronizers are controlled by the lever to control the connection relation of the two sun magnetic gears and the input shaft.
Further, the present invention can obtain four different transmission ratio outputs, and the speed changing portion is controlled by the shift lever and the synchronizer. Further, the center distances of the sun magnetic gear and the planet magnetic gears in the same group in the present invention are the same.
Further, the number of the planet gear rotating shafts I and the number of the planet gear rotating shafts II are the same as that of the planet magnetic gears in each gear set.
Further, the plurality of planet gear rotating shafts I are connected to the same output end planet carrier, and the plurality of planet gear rotating shaft II are connected to the same input end planet carrier.
Further, the plurality of magnetic gears are evenly distributed on the circumferential direction of the corresponding sun magnetic gears thereof.
The magnetic gear portion is a magnetic gear with evenly alternated N poles and S poles manufactured by using permanent magnets, and a plurality of pairs of input gears and output gears with different transmission ratios and the same center distance are manufactured. As magnetic gear machining does not need to consider the requirements of modulus, a proper number of magnetic poles (i.e., the number of teeth) can be machined according to design needs.
The speed changing portion can obtain a plurality of different transmission ratio outputs, and is controlled by the shift lever and the synchronizer. The speed changing portion adopts a plurality of groups of sun magnetic gears and planet magnetic gears with different transmission ratios and the same center distance, and the sun magnetic gears are not directly connected with the input shaft. The plurality of shift levers of the speed changing portion control the movement of the synchronizers having the function of connecting and disconnecting sun gears and the input shaft. When the shift levers drive the synchronizers to work, the corresponding sun magnetic gears are connected with the input shaft, so as to achieve the function that the output planet carrier completes different transmission ratio outputs.
The present invention has the following advantages:
1. by replacing the function of an outer gear ring with the function of the two planet carriers of the ringless planet gear, the movement of the ringless planet magnetic gear is realized, the movement precision is improved, and the error generated by the gear ring is avoided;
2. the ringless planet gear maintains the original advantages of the planet gear, such as compact structure, small size, capability of achieving a large transmission ratio, etc.;
3. no mechanical contact occurs between the magnetic gears, which reduces the vibration and noise of the transmission mechanism., and the gears can realize self-protection when overloaded and are not easy to damage;
4. the magnetic gears do not require lubrication, thus avoiding pollution of lubricating oil, so that cleanness and environment protection are achieved;

Term interpretation part: the planet magnetic gears and center magnetic gears as described in the present invention are all magnetic gears with evenly distributed N poles and S poles manufactured by permanent magnets, as shown in FIG. 1.
As introduced in the Background of the Invention, the planet gear in the prior art usually adopts the 2K-H planet transmission technology, and is most typically composed of several structures including sun magnetic gears, planet gears, gear rings, planet carriers, etc. In such a structure, the gear ring is an internal gear, which functions to be meshed with the planet gear. However, the error of the gear ring is an important factor causing the error of the planet gear. In order to ensure the precision of operation of the planet gear, it is usually required that the internal gear has higher machining precision, which increases the difficulty of production and machining. In order to solve the above technical problem, the present invention provides a ringless planet magnetic gear changing system.
In the present invention, four pairs of input gears and output gears with different transmission ratios and the same center distance are manufactured. As magnetic gear machining does not need to consider the requirements of modulus, a proper number of magnetic poles (i.e., the number of teeth) can be machined according to design needs. The numbers of magnetic poles of the four input gears are respectively 8, 12, 16 and 16, the numbers of magnetic poles of the corresponding output gears are respectively 16, 16, 16 and 8, and the gear ratios of the corresponding input gears and output gears are sequentially 1:2, 3:4, 1:1 and 2:1.
As shown in FIG. 2, the ringless planet gear portion in the present invention is designed by replacing the traditional 2K-H planet gear with a double planet carrier. The principle of the ringless planet gear is as shown in FIG 2, gear S is a sun gear, gear P is a planet gear, and KI and K2 are two planet carriers respectively. Two mounting holes are machined on the planet gear P and are connected to the two planet carriers respectively. In the present invention, the sun gear S is used as an input to drive KI and K2 to move, K2 is used as an output of the output end planet carrier, and KI supports the input end planet carried, without applying additional external force.
In the present invention, one of two mounting holes of the planet gear P is located at the center position for mounting the output end planet carrier Q2, and the other one has a certain eccentric distance with the planet carrier for mounting the input end planet carrier QI. As the mounting holes are eccentric, the center of rotation of QI is not concentric with the sun gear S, the eccentric distance between QI and S is equal to the distance of the two machined mounting holes of the planet gear P. In the design of the present invention, each sun gear needs to mesh three planet gears spaced by 120 degrees to ensure smooth movement, that is, the planet carrier also needs to be connected to the three planet gears at the same time. Therefore, a hollow circle is machined at the center position of the input end planet carrier KI to adapt to the eccentricity during the movement and avoid interference with the input shaft. The output end planet carrier K2 is connected to the mounting hole at the center position, so that K2 has the same center of rotation as the input shaft.
FIG. 3 is a view containing the position relationship of four sets of sun magnetic gears and one planet magnetic gear meshed therewith. The sun magnetic gears are not directly connected to the input shaft, but are connected by THE synchronizers. In the solution, the shift lever I and the shift lever II control the movement of the synchronizers a, b, c, d, so that the four sun magnetic gears are respectively connected with the input shaft, the input shaft inputs a certain rotating speed, the rotating speed of the output planet carrier changes along with different gear ratios of the sun magnetic gears and the planet magnetic gears meshed therewith to realize variation of the rotating speeds at the five gears and implement the function of the speed changer.
The three planet magnetic gears in the present invention are distributed at intervals of 120 degrees to ensure the stability of the movement.
The number of the planet gear rotating shaft 110 and the number of the planet gear rotating shaft II 5 are the same as that of the planet magnetic gears in each gear set. In the present invention, three planetary rotating shaft I and three planetary rotating shafts II are respectively provided, the three planet gear rotating shafts I are connected to the same output end planet carrier, and the three planet gear rotating shafts II are connected to the same input end planet carrier.
As shown in FIG 3, the shift lever I 20 of the present invention can move left and right. When it moves left, the synchronizer a is driven to connect the sun magnetic gear A with the input shaft; when it moves right, the synchronizer b is driven to connect the sun magnetic gear B with the input shaft; when the shift lever I is in the intermediate position, the synchronizers a and b are automatically disconnected and stop working. According to the same principle, the shift lever II 16 can control of the synchronizers c and d.
As shown in FIG. 4, in order to solve the problem that the input end planet carrier is eccentric in the movement process, a circle for preventing interference is machined at the center of the planet carrier to avoid interference between the planet carrier and the input end.
The specific structure is as follows:
The present invention includes an input shaft 1 on which an input end planet carrier 4 and a sun magnetic gear A 21, a sun magnetic gear B 18, a sun magnetic gear C17 and a sun magnetic gear D 16 are mounted, wherein each sun magnetic gear is meshed with three planet magnetic gears to form a group, and centers of four planet magnetic gears (a planet magnetic gear E 6, a planet magnetic gear F 7, a planet magnetic gear G 8, and a planet magnetic gear H 9) in different groups and in the same direction are connected to the same planet gear rotating shaft I 10 on the same straight line, three planet gear rotating shafts I 10 are provided and connected to an output end planet carrier 11, the input end planet carrier is connected to three planet gear rotating shafts II 5, the three planet gear rotating shaft II 5 are eccentrically connected to the four planet magnetic gears (the planet magnetic gear E 6, the planet magnetic gear F 7, the planet magnetic gear G 8, and the planet magnetic gear H 9) in different groups and in the same direction, and the connections of the sun magnetic gear A 21, the sun magnetic gear B 18, the sun magnetic gear C17 and the sun magnetic gear D 16 and the input shaft are controlled by the synchronizer and the shift lever, thereby achieving output at different speeds.
Further, different groups of sun magnetic gears and planet magnetic gears form different transmission ratios.
Further, one end of the input shaft 1 is mounted on a frame 3 by a pair of frame bearings 2, and the other end of the input shaft is mounted on the output end planet carrier 11 by a bearing 12.
Further, an output shaft end of the output end planet carrier 11 is also mounted on the frame 13 by a bearing 14; a button mounted on the output shaft of the output end planet carrier 11 is used for connection with other components.
Further, two synchronizers and one shift lever located between the two synchronizers are mounted between every two sun magnetic gears, and the two synchronizers are controlled by the lever to control the connection relation of the two sun magnetic gears and the input shaft. The present invention includes four synchronizers and two shift levers.
Further, the present invention can obtain four different transmission ratio outputs, and the speed changing portion is controlled by the shift lever and the synchronizer.
Further, the center distances of the sun magnetic gear and the output magnetic gears in each group in the present invention are the same.
The gear change is specifically achieved through the following method.
Zero gear: when the speed changer is in a zero gear state, the shift levers I and II are both in the intermediate positions and are not working, so that the sun magnetic gears are not connected with the input shaft, resulting in that the input shaft is idle and the output rotating speed of the output planet carrier is 0.
First gear: when the speed changer is in a first gear state, the shift lever I is shifted to move left to drive the synchronizer a so as to connect the input shaft to the sun magnetic gear A, and the shift lever II is in an intermediate position and not working. The sun magnetic gear A drives the planet magnetic gear E to move, the gear ratio of the sun magnetic gear A to the planet magnetic gear E is 1:2, and the output planet carrier realizes a low-speed output.
Second gear: when the speed changer is in a second gear state, the shift lever I is shifted to move right to drive the synchronizer b so as to connect the input shaft to the sun magnetic gear B, and the shift lever II is in an intermediate position and not working. The sun magnetic gear B drives the planet magnetic gear F to move, and the gear ratio of the sun magnetic gear B to the planet magnetic gear F is 3:4. The output rotating speed of the output planet carrier at the second gear is increased to a certain extent compared with that at the first gear.
Third gear: when the speed changer is in a third gear state, the shift lever I is in an intermediate position and not working, the shift lever II is shifted to move left to drive the synchronizer c so as to connect the input shaft to the sun magnetic gear G, and the gear ratio of the sun magnetic gear C to the planet magnetic gear G is 1:1. The output rotating speed of the output planet carrier at the third gear is further increased compared with that at the second gear.
Fourth gear: when the speed changer is in a fourth gear state, the shift lever I is in an intermediate position and not working, the shift lever II is shifted to move right to drive the synchronizer so as to connect the input shaft to the sun magnetic gear H, and the gear ratio of the sun magnetic gear D to the planet magnetic gear H is 2:1. The output rotating speed of the output planet carrier at the fourth gear is further increased compared with that at the third gear.
The speed changer realizes variation of different transmission ratios through the five-gear control, and can further expand variation values of the transmission ratios by assembling different proportions of input magnetic gears and output magnetic gears.
The above description is only the preferred embodiments of the present application, and is not intended to limit the present application. The person skilled in the art can make various modifications and changes to the present application. Any modifications, equivalent substitutions, improvements and the like made within the spirit and principles of the present application should be included within the scope of the present application.
