[0053] Currently, small module gear transmission is a form of micro transmission, which has obvious differences from traditional gears in terms of design, manufacturing, installation and application. With the development of precision instruments and micro transmission systems, etc., it has a broad application prospect; at the same time, with the increasing maturity of die technology and plastic technology, in some fields, small module plastic gears are gradually showing a trend of replacing metal gears, reflecting important research value. By improving the manufacturing accuracy, the performance of small module gears can be improved, and through the error simulation and performance testing of small module gears, it can provide a basis and ideas for further precision gear profile modification and design optimization.

[0054] In the existing technical solutions, the relative position adjustment of the gear pair mostly uses a micro-motion platform. The imported high-precision micro-motion adjustment platform alone cannot guarantee the adjustment accuracy and is easy to achieve high-precision micro-motion adjustment only when used in combination with a driver and a sensor; there is a return error in the micro-motion platform itself, and the accuracy retention is not good when repeatedly used during micro-adjustment, and it is difficult to maintain stability in a high-frequency vibration environment when used in combination; the rotation center of the rotary platform and the pitching platform is usually located at the center of the platform, far from the actual required position, and a large amount of displacement compensation is required during adjustment to ensure gear meshing, resulting in a large error.

[0055] However, the scale of small module gears is small, and during the error simulation test, large error values are easily generated during the micro-adjustment of the relative position of the gear pair.

[0056] Please refer to Figures 1 - 7, an embodiment of the present invention provides a high-speed small module gear test platform 200, which includes a base 210, a mounting component 220, a test component 230, and a limiting component 240;

[0057] The mounting component 220 is movably connected to the base 210; the test component 230 is connected to the mounting component 220, and the test component 230 is used to mount the first test gear 10 and the second test gear 20, and the first test gear 10 meshes with the second test gear 20;

[0058] The limiting component 240 is connected to the base 210 and the mounting component 220, and the limiting component 240 is used to limit the movement of the mounting component 220 relative to the base 210.

[0059] Please refer to Figures 1 - 7 , the working principle of this high-speed small module gear test platform 200 is:

[0060] During the test using this high-speed small module gear test platform 200, by connecting the first test gear 10 and the second test gear 20 to the test component 230, and adjusting the relative positions of the first test gear 10 and the second test gear 20 through the displacement of the mounting component 220 relative to the base 210, it is possible to reduce the displacement during the test and effectively improve the relative position accuracy during fine adjustment, thereby reducing the test error of this high-speed small module gear test platform 200.

[0061] Specifically, in this embodiment, during the test, in order to test the first test gear 10 and the second test gear 20, therefore, the test component 230 includes a motor 231, a first rotational speed, rotation angle, and torque sensor 232, a first bearing seat 233, a hysteresis brake 234, a second rotational speed, rotation angle, and torque sensor 235, and a second bearing seat 236;

[0062] The output end of the motor 231 is drivingly connected to the input end of the first rotational speed, rotation angle, and torque sensor 232. The first test gear 10 is rotatably connected to the first bearing seat 233, and the first test gear 10 is drivingly connected to the output end of the first rotational speed, rotation angle, and torque sensor 232;

[0063] The second test gear 20 is rotatably connected to the second bearing seat 236, and the second test gear 20 is drivingly connected to the input end of the second rotational speed, rotation angle, and torque sensor 235; the output end of the second rotational speed, rotation angle, and torque sensor 235 is drivingly connected to the hysteresis brake 234.

[0064] Thus, through such a setting method, the output of the motor 231 can be used to drive the first test gear 10 to rotate. Through the meshing of the first test gear 10 and the second test gear 20, the power transmission can be completed, so that the working conditions of the first test gear 10 and the second test gear 20 can be detected by the first rotational speed, angle, and torque sensor 232 and the second rotational speed, angle, and torque sensor 235, and then the tests on the first test gear 10 and the second test gear 20 can be completed.

[0065] Moreover, during the process of connecting the first test gear 10 and the second test gear 20 to the test assembly 230, in order to facilitate the adjustment of the distance between the first test gear 10 and the second test gear 20 in the axial direction of their axes, the test assembly 230 further includes a first rotating shaft 237, a second rotating shaft 238, a first positioning washer 239, and a second positioning washer 251.

[0066] The first rotating shaft 237 is rotatably connected to the first bearing seat 233, and one end of the first rotating shaft 237 is in transmission connection with the output end of the first rotational speed, angle, and torque sensor 232; the first test gear 10 is connected to the other end of the first rotating shaft 237, and the first positioning washer 239 is sleeved on the first rotating shaft 237 and abuts against one side of the first test gear 10 facing the first bearing seat 233.

[0067] The second rotating shaft 238 is rotatably connected to the second bearing seat 236, and one end of the second rotating shaft 238 is in transmission connection with the output end of the second rotational speed, angle, and torque sensor 235; the second test gear 20 is connected to the other end of the second rotating shaft 238, and the second positioning washer 251 is sleeved on the second rotating shaft 238 and abuts against one side of the second test gear 20 facing the first bearing seat 233.

[0068] Specifically, by adjusting the first positioning washer 239 and the second positioning washer 251, the distance between the first test gear 10 and the first bearing seat 233 can be adjusted, and the distance between the second test gear 20 and the second bearing seat 236 can be adjusted, so that the axial distance between the first test gear 10 and the second test gear 20 can be adjusted.

[0069] Please refer to Figures 1 - 7 In this embodiment, when setting the first rotating shaft 237 and the second rotating shaft 238, the first rotating shaft 237 includes a first hollow shaft 252, a first elastic clamping cylinder 253, and a first optical shaft 254; the first hollow shaft 252 is rotatably connected to the first bearing seat 233 and is in transmission connection with the output end of the first rotational speed, angle, and torque sensor 232. The first optical shaft 254 is connected to the first hollow shaft 252 through the first elastic clamping cylinder 253. Both the first positioning washer 239 and the first test gear 10 are connected to the first optical shaft 254.

[0070] The second rotating shaft 238 includes a second hollow shaft 255, a second elastic clamping cylinder 256 and a second optical shaft 257; the second hollow shaft 255 is rotatably connected to the second bearing seat 236 and is drivingly connected to the output end of the second rotational speed, rotation angle and torque sensor 235. The second optical shaft 257 is connected to the second hollow shaft 255 through the second elastic clamping cylinder 256. Both the second positioning washer 251 and the second test gear 20 are connected to the second optical shaft 257.

[0071] It should be noted that in the above content, the motor 231 is connected to the input end of the first rotational speed, rotation angle and torque sensor 232 through a bellows coupling, and the output end of the first rotational speed, rotation angle and torque sensor 232 is connected to the first test gear 10; the hysteresis brake 234 is connected to the output end of the second rotational speed, rotation angle and torque sensor 235 through a bellows coupling, and the input end of the second rotational speed, rotation angle and torque sensor 235 is connected to the second test gear 20; the connection manner between the first rotating shaft 237 and the first bearing seat 233 is the same as that between the second rotating shaft 238 and the second bearing seat 236. Specifically, taking the connection manner between the first rotating shaft 237 and the first bearing seat 233 as an example:

[0072] The first test gear 10 is assembled on the first optical shaft 254 and is connected to the first hollow shaft 252 through the first elastic clamping cylinder 253 and a locking nut, and is axially positioned through the first positioning washer 239; the second test gear 20 is assembled on the second optical shaft 257 and is connected to the second hollow shaft 255 through the second elastic clamping cylinder 256 and a locking nut, and is axially positioned through the second positioning washer 251.

[0073] Moreover, the first rotational speed, rotation angle and torque sensor 232 and the first bearing seat 233 are connected to the mounting plate through bolts. A sealed double-row angular contact ball bearing is installed in the first bearing seat 233. The bearing end cover is connected to the first bearing seat 233 through bolts, completely restricting the outer ring of the bearing; the inner ring of the bearing positions the first hollow shaft 252, and the first hollow shaft 252 is locked to the output end of the first rotational speed, rotation angle and torque sensor 232 through bolts; the first optical shaft 254 is assembled and locked in the first hollow shaft 252 through the first elastic clamping cylinder 253 and a locking nut. The first test gear 10 and the locking nut are axially positioned through the first positioning washer 239. By changing the thickness of the first positioning washer 239, the overall axial translation of the first test gear 10 and the first optical shaft 254 can be realized, thereby realizing the adjustment of the translational freedom of the first test gear 10 on the high-speed small module gear test platform 200 in the first direction.

[0074] When installing the first mounting plate 221 and the second mounting plate 222, to improve the stability of the first mounting plate 221 and the second mounting plate 222 and leave room for the first mounting plate 221 and the second mounting plate 222 to adjust their positions relative to the base 210, the mounting assembly 220 includes a first mounting plate 221, a second mounting plate 222, and a plurality of locking bolts 223; a plurality of elongated holes or slots 224 are provided in both the first mounting plate 221 and the second mounting plate 222, and each elongated hole or slot 224 is correspondingly fitted with a locking bolt 223;

[0075] The motor 231, the first rotational speed, rotation angle and torque sensor 232, and the first bearing seat 233 are all connected to the first mounting plate 221; the hysteresis brake 234, the second rotational speed, rotation angle and torque sensor 235, and the second bearing seat 236 are all connected to the first mounting plate 221. Moreover, the motor 231, the first rotational speed, rotation angle and torque sensor 232, and the first bearing seat 233 are bolted to the first mounting plate 221; the hysteresis brake 234, the second rotational speed, rotation angle and torque sensor 235, and the second bearing seat 236 are bolted to the second mounting plate 222;

[0076] Thus, when installing the first mounting plate 221 and the second mounting plate 222, by tightening the plurality of locking bolts 223 with the base 210, the first mounting plate 221 and the second mounting plate 222 can be fixed to the base 210; and when the plurality of locking bolts 223 are loose with respect to the mounting plate, since the structures on the first mounting plate 221 and the second mounting plate 222 for cooperating with the locking bolts 223 are elongated holes or slots 224, through the movement of the locking bolts 223 relative to the elongated holes or slots 224, the first mounting plate 221 and the second mounting plate 222 can be moved relative to the base 210.

[0077] Further, please refer to Figures 1 - 7 , in this embodiment, to simplify the adjustment steps of the positions of the first test gear 10 and the second test gear 20, the mounting assembly 220 further includes a first baffle 225, at least one first positioning block 226, and at least one second positioning block 227;

[0078] The first baffle 225 is connected to the base 210 and abuts against one side of the first mounting plate 221 and the second mounting plate 222 along the direction from the first mounting plate 221 to the second mounting plate 222; the limiting assembly 240 abuts against the other side of the first mounting plate 221 and the second mounting plate 222;

[0079] The first positioning block 226 is located between the first mounting plate 221 and the first baffle plate 225 , and the second positioning block 227 is located between the first baffle plate 225 and the second mounting plate 222 . The first positioning block 226 or the second positioning block 227 has an inclined surface facing the first baffle plate 225 or away from the first baffle plate 225 .

[0080] That is, when the direction from the first mounting plate 221 to the second mounting plate 222 is the first direction, the first positioning block 226 and the second positioning block 227 are adjusted to enable the first mounting plate 221 and the second mounting plate 222 to move in a direction perpendicular to the first direction, thereby adjusting the positions of the first test gear 10 connected to the first mounting plate 221 and the second test gear 20 connected to the second mounting plate 222; and, when the direction from the first mounting plate 221 to the second mounting plate 222 is parallel to the axial direction of the first rotating shaft 237, the first positioning block 226 and the second positioning block 227 are adjusted to enable the first mounting plate 221 and the second mounting plate 222 to move in a direction perpendicular to the axial direction of the first rotating shaft 237;

[0081] From the above content, it can be known that by adjusting the first positioning washer 239 and the second positioning washer 251, the axial distance between the first test gear 10 and the second test gear 20 can be adjusted; and by adjusting the first positioning block 226 and the second positioning block 227, the first mounting plate 221 and the second mounting plate 222 can be moved along the axial direction perpendicular to the first rotating shaft 237; and the direction of the first rotating shaft 237 is consistent with the axial direction of the first test gear 10; therefore, by adjusting the first positioning washer 239 and the second positioning washer 251, the position between the first test gear 10 and the second test gear 20 can be adjusted along the first direction, and by adjusting the first positioning block 226 and the second positioning block 227, the first mounting plate 221 and the second mounting plate 222 can be moved along the second direction, wherein the first direction is perpendicular to the second direction.

[0082] It should also be noted that when setting the first positioning block 226 or the positioning block, the side of the first positioning block 226 or the second positioning block 227 facing or departing from the first baffle 225 can be made into an inclined surface. By such a setting method, when the side of the first positioning block 226 facing or departing from the first baffle 225 is an inclined surface, the first mounting plate 221 can be inclined relative to the first direction. Similarly, when the side of the second positioning block 227 facing or departing from the first baffle 225 is an inclined surface, the second mounting plate 222 can be inclined relative to the first direction, thereby causing a deflection angle between the axis of the first test gear 10 and the axis of the second test gear 20. It should be noted that under the action of the second positioning block 227, the deflection of the first mounting plate 221 or the second mounting plate 222 is to adjust the deflection angle of the axis of the first test gear 10 and the axis of the second test gear 20 on the horizontal plane.

[0083] Furthermore, please refer to Figures 1 - 7 , in this embodiment, the mounting assembly 220 further includes at least one third positioning block 228;

[0084] The surface of the first mounting plate 221 or the second mounting plate 222 in contact with the base 210 is provided with a limiting groove; the limiting groove cooperates with the third positioning block 228;

[0085] Wherein, the side surface of the third positioning block 228 facing or departing from the base 210 is an inclined surface.

[0086] Through such a setting method, after the third positioning block 228 cooperates with the limiting groove, the first mounting plate 221 or the second mounting plate 222 provided with the limiting groove can be deflected relative to the base 210; and when setting the limiting groove and the third positioning block 228, the end close to the second baffle 261 can be made lower than the other end. Such a setting can enable the first mounting plate 221 or the second mounting plate 222 provided with the limiting groove to rotate around the second direction axis and deflect relative to the base 210, thereby causing a deflection between the axis of the first test gear 10 and the axis of the second test gear 20. It should be noted that under the action of the third positioning block 228, the deflection of the first mounting plate 221 or the second mounting plate 222 is to adjust the deflection angle of the axis of the first test gear 10 and the axis of the second test gear 20 on the vertical plane. And along the second direction, the side of the first mounting plate 221 or the second mounting plate 222 departing from the limiting groove has an annular surface, which is convenient for the first mounting plate 221 or the second mounting plate 222 to deflect relative to the base under the action of the second positioning block 227 and the third positioning block 228.

[0087] Furthermore, please refer to Figures 1 - 7, in this embodiment, the mounting assembly 220 further includes a second baffle 261. The second baffle 261 is connected to the base 210 and abuts against the side of the first mounting plate 221 facing away from the second mounting plate 222; the limiting assembly 240 abuts against the side of the second mounting plate 222 facing away from the first mounting plate 221. Through such a setting method, the movement of the first mounting plate 221 in the direction away from the second mounting plate 222 can be restricted.

[0088] Moreover, when setting the limiting assembly 240, the limiting assembly 240 includes a first mounting platform 241, a first abutting rod 242, a second mounting platform 243, a second abutting rod 244, a third mounting platform 245 and a third abutting rod 246; the first abutting rod 242 is threadedly connected to the first mounting platform 241, and the first abutting rod 242 is used to abut against the side of the first mounting plate 221 facing away from the first baffle 225; the second abutting rod 244 is threadedly connected to the second mounting platform 243, and the second abutting rod 244 is used to abut against the side of the second mounting plate 222 facing away from the first baffle 225; the third abutting rod 246 is threadedly connected to the third mounting platform 245, and the third abutting rod 246 is used to abut against the side of the second mounting plate 222 facing away from the first mounting plate 221.

[0089] Thus, by rotating the first abutting rod 242, the second abutting rod 244 and the third abutting rod 246 to make them abut against the first mounting plate 221 or the second mounting plate 222 and cooperate with the limiting effects of the first baffle 225 and the second baffle 261, the stability of the first mounting plate 221 and the second mounting plate 222 can be maintained.

[0090] Further, please refer to Figures 1 - 7 , in this embodiment, for the noise test of the gears, therefore, the high-speed small module gear test platform 200 further includes a first sound insulation cover, a second sound insulation cover and a noise tester;

[0091] The first sound insulation cover is connected to the first mounting plate 221, and the motor 231, the first rotational speed angle torque sensor 232 and the first bearing seat 233 are all accommodated in the first sound insulation cover, and the first test gear 10 is located outside the first sound insulation cover;

[0092] The second sound insulation cover is connected to the second mounting plate 222, and the hysteresis brake 234, the second rotational speed angle torque sensor 235 and the second bearing seat 236 are all accommodated in the second sound insulation cover, and the second test gear 20 is located outside the second sound insulation cover;

[0093] The noise tester is located outside the first sound insulation cover and the second sound insulation cover and at the meshing position of the first test gear 10 and the second test gear 20.

[0094] Moreover, the first sound insulation cover and the second sound insulation cover are provided with shaft ports and wire outlets, which are used for power lines to pass through and for the first rotating shaft 237 or the second rotating shaft 238 to pass through. In order to avoid the noise inside the first sound insulation cover and the second sound insulation cover from interfering with the operation of the noise tester, seals are provided at the shaft ports and wire outlets to absorb non-gear meshing noise.

[0095] In summary, please refer to Figures 1 - 7 , in this embodiment, when setting the first positioning block 226 and the second positioning block 227, two first positioning blocks 226 are set, and the surfaces of the first positioning block 226 in contact with the first mounting plate 221 and the first baffle 225 are both flat surfaces, while the surface of the second positioning block 227 in contact with the second mounting plate 222 is an inclined surface;

[0096] Thus, by adjusting the length of the two first positioning blocks 226 in the second direction, the interval between the first mounting plate 221 and the first baffle 225 can be adjusted, and further, the interval between the axis of the first test gear 10 and the axis of the second test gear 20 can be adjusted in the second direction.

[0097] When setting the third positioning block 228 and the limiting groove, the limiting groove is opened on the second mounting plate 222, and the surface of the third positioning block 228 facing the second mounting plate 222 is an inclined surface, and along the second direction, the height of the end of the third positioning block 228 close to the second baffle 261 is lower than or the height of the other end. Thus, through such a setting method, the second mounting plate 222 can be deflected relative to the axis of the second rotating shaft 238, and further, the included angle between the axis of the first test gear 10 and the axis of the second test gear 20 can be adjusted.

[0098] It should be noted that when adjusting the position of the first mounting plate 221 relative to the base 210, the locking bolt 223 on the first mounting plate 221 needs to be loosened, and the first abutting rod 242 is spaced from the first mounting plate 221. Similarly, when adjusting the position of the second mounting plate 222 relative to the base 210, the locking bolt 223 on the second mounting plate 222 needs to be loosened, and the second abutting rod 244 and the third abutting rod 246 are spaced from the second mounting plate 222.

[0099] In summary, based on the above content, please refer to Figures 1 - 7 , the high-speed small module gear test platform 200 can adjust the two translational degrees of freedom and the two rotational degrees of freedom of the first test gear 10 and the second test gear 20 either singly or in combination;

[0100] The displacement of the first test gear 10 and the second test gear 20 in the first direction can be adjusted by the first positioning washer 239 and the second positioning washer 251; and through the setting of the inclined surface of the second positioning block 227, the deflection angle of the second test gear 20 on the horizontal plane can be adjusted; and through the third positioning block 228, the deflection angle of the second test gear 20 on the plumb plane can be adjusted;

[0101] By discretizing the proposed adjustment range and designing multiple groups of adjustment positioning parts, the installation of a pair of gears on parallel axes, intersecting axes, and staggered axes within a certain installation distance and installation angle range can be realized and the corresponding errors can be simulated; moreover, the first positioning washer 239 and the second positioning washer 251 can be designed as multiple thin washers, and the adjustment can be achieved by changing the number of thin washers;

[0102] Moreover, the first positioning block 226 can be adjusted by using a set of length gauges; while the second positioning block 227 and the third positioning block 228 can be adjusted by using a combination of a set of length gauges and a set of angle gauges.

[0103] On the basis of the above structure, through the settings of the first abutting rod 242, the second abutting rod 244, the third abutting rod 246, the first baffle 225 and the second baffle 261, it can be ensured that the rack plate and the positioning parts maintain close contact during the process of bolt connection, and the installation errors caused by bolt connection can be collected and reduced.

[0104] The high-speed small module gear test platform 200 has the following advantages:

[0105] The high-speed small module gear test platform 200 is easy to adjust, disassemble, replace, and has good repeatability and accuracy retention as a whole.

[0106] The high-speed small module gear test platform 200 realizes the movement of the first test gear 10 and the second test gear 20 in two degrees of freedom directions in the first direction and the second direction, and at the same time realizes the deflection of the axes of the first test gear 10 and the second test gear 20 on the horizontal plane and the plumb plane; by associating four adjustment methods and discretizing the proposed adjustment range, the high-precision installation of the installation distance and installation angle of a pair of gear shafts within a certain range can be realized, and the installation distance and installation angle errors can be simulated; the non-gear meshing part is isolated by the sound insulation cover and the wave-absorbing material to reduce the noise interference. Due to the small scale, ensuring the geometric machining accuracy of relevant parts, and using standard sets of length measuring tools and angle measuring tools, high-precision adjustment can be achieved, which is economical and practical. The structure is compact, with good vibration resistance, applicable to a large range of rotational speeds and transmission ratios, and can test the transmission efficiency, transmission error, vibration and noise, etc. of high-speed and low-speed small module gears. At the same time, it can also be used to study the influence of the installation angle errors of plane intersection and space stagger, the radial and axial installation distance errors, and lubrication on the performance of small module gears.
