Description

Technical Field

[0001] This invention relates to the field of speed reducer production and testing technology, specifically to a planetary gear processing device for gear reducer production. Background Technology

[0002] New energy vehicles have high-speed drive motors, while the wheel speeds required for vehicle operation are relatively low, and a large torque output is needed. Gear reducers can achieve speed reduction and torque increase through gear transmission, thereby matching the motor characteristics with the vehicle's driving needs and ensuring the vehicle's power performance and driving efficiency. In the gear reducer manufacturing field, planetary gear sets, as core transmission components, have their transmission efficiency, noise level, and service life directly affected by their machining accuracy and assembly quality. Currently, there are still many technical challenges in the machining and testing of planetary gear sets, mainly in the following aspects: limited adaptability, as traditional testing equipment is mostly designed for specific specifications. The design of the sun gear, planet gears, and ring gear is not flexible enough to accommodate gear sets of different sizes. When producing different models of reducers, the entire set of testing fixtures must be replaced, which not only increases equipment costs but also prolongs production changeover time and reduces production efficiency. The testing process is cumbersome. In the production testing of planetary gear sets, the existing equipment has complicated installation and positioning operations, requiring manual and repeated calibration of the meshing clearance between gears. At the same time, unloading is difficult after the test, requiring manual removal of the ring gear, planet gears, and sun gear in sequence. If the test planet gears are removed from the inside, the sun gear or ring gear must be removed first before the planet gears can be disassembled, which increases the labor intensity.

Detailed Implementation

[0027] The following will refer to the appendices in the embodiments of the present invention. Figures 1-7 To provide further details.

[0028] This invention provides a technical solution: a planetary gear processing device for producing gear reducers, comprising a main structure 1 and a testing structure, wherein the testing structure is fixedly mounted on the main structure 1; wherein the main structure 1 is used for bearing and monitoring, and the testing structure is used to simultaneously engage the sun gear, planet gears and ring gear, and is capable of driving the rotation of the combined gear set.

[0029] As a preferred embodiment, the main structure 1 further includes a base 11, a controller assembly 12, a hanger 13, a camera 14, a test platform 15, three stop arms 16, and three first bolts 17. The controller assembly 12 is fixedly mounted on the front end of the base 11. One end of the hanger 13 is fixedly mounted on the left end of the base 11. The hanger 13 is an F-shaped frame. The other two ends of the hanger 13 are located above the base 11. The camera 14 is fixedly mounted on one end of the hanger 13, and the camera 14 is opposite to the base 11. The test platform 15 is fixedly mounted on the other end of the hanger 13, and the test platform 15 is located at the camera. Below the head 14, the test platform 15 has a wheel retraction port 5 in the middle. The three stop arms 16 are all concave, and each stop arm 16 has a moving port 6 in the middle of one end. The three stop arms 16 are respectively set on the upper wall of the test platform 15 and arranged in a triangular pattern. The three first bolts 17 respectively move through the moving ports 6 of the stop arms 16 and are screwed into the test platform 15. The camera 14 is raised to a certain height by the hanger 13. The stop arms 16 are set on the test platform 15. The direction and position of the stop arms 16 can be adjusted by the first bolts 17. The stop arms 16 are fitted on the sleeve 44 to bear the test gear and gear.

[0030] More specifically, through the cooperation of the movable port 6 and the first bolt 17, the stop arm 16 can adapt to the positioning of gear rings of different diameters and the bearing of planetary gears. The F-type hanger 13 ensures that the relative position of the camera 14 and the test platform 15 is fixed, and the vertical shooting angle avoids visual deviation and improves the reliability of monitoring data.

[0031] As a preferred embodiment, the test structure further includes a drive assembly 2, a first pitch adjustment assembly 3, and three second pitch adjustment assemblies 4. The drive assembly 2 is fixedly mounted on the upper wall of the base 11 and located in front of the test platform 15. The first pitch adjustment assembly 3 is fixedly mounted on the drive assembly 2 and moves up and down via the drive assembly 2. The three second pitch adjustment assemblies 4 are respectively mounted on the first pitch adjustment assembly 3 and are arranged clockwise at equal intervals in three directions. The height of the first pitch adjustment assembly 3 and the second pitch adjustment assemblies 4 is controlled by the drive assembly 2 to test the unloading gear. The angle and distance of the three planetary gears are adjusted by the first pitch adjustment assembly 3 to fit gear sets of different sizes. The equidistant distance of the three planetary gears is adjusted by the second pitch adjustment assemblies 4.

[0032] More specifically, when it is necessary to adjust the height of the test structure (such as loading and unloading the gear set), the controller group 12 controls the hydraulic cylinder unit 21 to extend and retract, and the drive frame 22 drives the first adjusting component 3 and the second adjusting component 4 to rise and fall synchronously, so as to realize the separation or docking of the sleeve shaft and the gear set. During the test, the first motor 24 starts, drives the gear (planetary gear) mounted on the first sleeve shaft 25 to rotate, and then drives the entire gear set to mesh and operate.

[0033] As a preferred embodiment, the drive assembly 2 further includes a pair of hydraulic cylinder units 21, a drive frame 22, a frame 23, a first motor 24, and a first shaft 25. The pair of hydraulic cylinder units 21 are symmetrically arranged on the upper front wall of the base 11. The drive frame 22 is fixedly arranged between the telescopic ends of the pair of hydraulic cylinder units 21. The frame 23 is F-shaped, with one end of the frame 23 fixedly arranged on the drive frame 22. The first motor 24 is fixedly arranged on one end of the frame 23. One end of the first shaft 25 movably passes through the other end of the frame 23, and one end of the first shaft 25 is connected to the drive end of the first motor 24. The hydraulic cylinder units 21 realize hydraulic drive telescopic movement, thereby driving the drive frame 22 to adjust its height. The first motor 24 drives one of the planetary gears to rotate on the first shaft 25. The first shaft 25 can pass through the wheel retraction port 5 of the test bench 15.

[0034] More specifically, when it is necessary to install or disassemble the gear set, the controller group 12 sends a command to the hydraulic cylinder unit 21, and the hydraulic system drives the extension and retraction end of the cylinder to extend or retract, thereby driving the drive frame 22 to rise and fall as a whole: during installation, the drive frame 22 rises, and the first set of shafts 25 moves upward synchronously with the frame 23, passes through the wheel unloading port 5 of the test bench 15, and then connects with the gear set (sun gear or planet gear) to be tested through the sleeve 44 until the gear set meshes with the gear ring positioned by the stop arm 16; during disassembly, the drive frame 22 descends, and the first set of shafts 25 drives the gear set to move downward synchronously, disengaging from the test bench 15 through the wheel unloading port 5, thus completing the unloading.

[0035] As a preferred embodiment, the first adjusting assembly 3 further includes an adjusting frame 31, a second motor 32, three helical gears 33, and three support plates 34. The adjusting frame 31 is fixedly mounted on the drive frame 22 and located behind the hydraulic cylinder unit 21. The adjusting frame 31 is concave. The second motor 32 is fixedly mounted on the drive frame 22, and its drive end is opposite to the adjusting frame 31. The first helical gear 33 is movably mounted in the middle of the adjusting frame 31 via a first axle 71, which movably passes through the drive frame 22 and is connected to the drive end of the second motor 32. The second helical gear 33 is movably mounted at the top of the adjusting frame 31 via the second axle 72 and meshes with the first helical gear 33. The third helical gear 33 is movably mounted on the adjusting frame 31 via a third axle 73. At the bottom, the third helical gear 33 is symmetrical to the second helical gear 33, and the third helical gear 33 meshes with the first helical gear 33. The third gear shaft 73 of the third helical gear 33 movably passes through the second gear shaft 72. The second gear shaft 72 and the third gear shaft 73 are both on the same vertical line as the first set of shafts 25. One end of a pair of support plates 34 is fixedly fitted onto the second gear shaft 72 and the third gear shaft 73, respectively. The pair of support plates 34 are located symmetrically on the left and right sides. One end of another support plate 34 is fixedly set on the lower wall of one end of the frame 23. The three support plates 34 are arranged at equal angles, and the other ends of the three support plates 34 are all located below the test platform 15. The second motor 32 is started, driving the helical gear 33 in the middle to rotate, realizing the opposite rotation of the other two symmetrical helical gears 33, and realizing the relative or opposite movement of the support plates 34.

[0036] More specifically, when it is necessary to adapt to gear sets of different sizes, the controller group 12 sends a command to the second motor 32. The drive end of the second motor 32 drives the first gear shaft 71 and the first helical gear 33 to rotate clockwise or counterclockwise, causing the two symmetrical helical gears 33 meshing with it to rotate under the opposite force. The second gear shaft 72 and the third gear shaft 73 respectively drive the corresponding support plate 34 to move, adjusting the distance of the second set of shafts 43 relative to the first set of shafts 25.

[0037] As a preferred embodiment, the second adjustable assembly 4 further includes an electric slide rail 41, a bearing seat 42, a second set of shafts 43, and several sleeves 44. The electric slide rail 41 is fixedly mounted on the support plate 34 and is parallel to the support plate 34. The bearing seat 42 is fixedly mounted on the electric slide rail 41 and is movable along the support plate 34. One end of the second set of shafts 43 is movably inserted into the other end of the bearing seat 42, and the second set of shafts 43 is identical to the first set of shafts 25. Several sleeves 44 are detachably mounted on the first shaft 25 and the second shaft 43. The inner diameter of the sleeves 44 is the same and they fit with the first shaft 25. The sleeves 44 can be fixed to the first shaft 25 by bolts. The shaft seat 42 is moved by the electric slide rail 41 to adjust the relative distance between the first shaft 25 and the second shaft 43. The outer diameter of the sleeves 44 is different to fit gears with different inner ring diameters. The stop arm 16 can be mounted on the sleeves 44.

[0038] More specifically, after the first pitch adjustment component 3 completes the coarse adjustment of the planetary gear angle and pitch, the controller group 12 sends a command to the electric slide rail 41. The slide rail slider drives the shaft seat 42 to move along the length direction of the support plate 34, thereby adjusting the relative distance between the second set of shafts 43 and the first set of shafts 25. When the pitch needs to be increased, the slider moves away from the first set of shafts 25, and the second set of shafts 43 moves synchronously until the meshing clearance between the planetary gear, the sun gear, and the gear ring reaches the preset value. No matter how the first set of shafts 25 and the second set of shafts 43 are adjusted, they form a triangular connection line and the second set of shafts 43 in the middle carries the sun gear.

[0039] Working principle:

[0040] Step 1: The equipment is placed stably on the base 11 in the main structure 1;

[0041] Step 2: During testing, after powering on the equipment, adjust the equipment using the controller group 12 according to the dimensions of the sun gear, planet gears, and gear ring in the gear set being processed and tested.

[0042] Step 3: By starting the second motor 32 on the drive frame 22, the first wheel shaft 71 is driven to rotate, which in turn drives the helical gear 33 located in the middle of the adjusting frame 31 in the first adjusting assembly 3 to rotate. By meshing with two other helical gears 33 located symmetrically above and below, the second wheel shaft 72 and the third wheel shaft 73 are driven to rotate in opposite directions, which ultimately drives the two pallets 34 to move relative to each other or in opposite directions, changing the relative distance of the second set of shafts 43 above and the distance relative to the first set of shafts 25 on the frame 23.

[0043] Step 4: At the same time, start the electric slide rail 41 in the second pitch adjustment assembly 4, which will drive the second set of shafts 43 on the shaft seat 42 to move, adjust the straight distance of the second set of shafts 43 relative to the first set of shafts 25, and make the second set of shafts 43 located below the frame 23 and on the tray 34 to be in the middle to support the sun gear.

[0044] Step 5: After adjustment, start the hydraulic cylinder unit 21 in the drive assembly 2 to drive the drive frame 22 to rise, thereby driving the first set of shafts 25 and the second set of shafts 43 to rise, causing the first set of shafts 25 and the second set of shafts 43 to pass through the wheel retraction port 5 on the hanger 13 and the test table 15, and move the stop arm 16, which is movably positioned by means of the first bolt 17 through the movable port 6, so that one end of the stop arm 16 is locked on the first set of shafts 25 and the second set of shafts 43 used to support the planetary gears;

[0045] Step 6: The corresponding sun gear and planet gear can be set on the first set of shafts 25 and the second set of shafts 43. Finally, the combined gear ring is set, and the gears are all supported and limited by the stop arm 16. According to different gears and gear shaft hole diameters, the corresponding sleeves 44 can be set on the first set of shafts 25 and the second set of shafts 43, and then the gear assembly processing test is performed.

[0046] After installation, the first motor 24 on the frame 23 can be started to drive the first set of shafts 25 to rotate, which in turn drives one of the planetary gears to rotate. By using the relative meshing transmission, the planetary gears, sun gear and gear ring are driven to rotate synchronously, and the camera 14 on the hanger 13 is used for imaging monitoring.

[0047] After testing, the hydraulic cylinder unit 21 can be retracted to lower the drive frame 22, which in turn lowers the sun gear, the first set of shafts 25, and the second set of shafts 43, causing the planetary gears and gear rings to be blocked and positioned on the stop arm 16 for unloading. After raising it again, the planetary gears and gear rings can be reinstalled for testing; the sun gear can also be replaced.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Other modifications or functional substitutions made by those skilled in the art to the technical solutions of the present invention, as long as they do not depart from the spirit and scope of the technical solutions of the present invention, should be covered within the scope of the claims of the present invention.
