[0029] More specifically, when it is necessary to adapt gear sets of different sizes, the controller group 12 sends instructions to the second motor 32, and the driving end of the second motor 32 drives the first wheel shaft 71 and the first bevel gear 33 to rotate clockwise or counterclockwise, driving the two symmetrical bevel gears 33 engaged with it to rotate under the reverse force, and the corresponding support plates 34 are driven to move through the second wheel shaft 72 and the third wheel shaft 73 respectively, thereby adjusting the distance between the second sleeve shaft 43 and the first sleeve shaft 25.

The outer diameters of the sleeves 44 are different and are used to fit gears with different inner ring diameters. The retaining arm 16 can be mounted on the sleeve 44.

[0031] More specifically, after the first distance adjustment component 3 completes the coarse adjustment of the planetary gear angle and spacing, the controller group 12 sends an instruction to the electric slide rail 41, and 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 sleeve shaft 43 and the first sleeve shaft 25: when the spacing needs to be increased, the slider moves away from the first sleeve shaft 25, and the second sleeve shaft 43 is displaced synchronously until the meshing clearance between the planetary gear and the sun gear and the gear ring reaches the preset value. No matter how the first sleeve shaft 25 and the second sleeve shaft 43 are adjusted, a triangular connecting line is formed and a second sleeve shaft 43 located in the middle supports the sun gear.

[0032] Working principle: Step 1: The device is placed stably on the base 11 in the main structure 1; Step 2: During the test, after the device is powered on, the controller group 12 is used to control the device according to the sizes of the sun gear, planetary gears, and ring gear in the gear set being tested. Step 3, i.e., by starting the second motor 32 on the driving frame 22, the first wheel shaft 71 is driven to rotate, thereby driving the bevel gear 33 located in the middle of the pitch adjusting frame 31 in the first pitch adjusting assembly 3 to rotate, and by engaging with the other two symmetrical bevel gears 33 located above and below, respectively driving the second wheel shaft 72 and the third wheel shaft 73 to rotate in opposite directions, and finally driving the two supporting plates 34 to move relative to or toward each other, thereby changing the relative distance between the second sleeve shaft 43 above and the distance relative to the first sleeve shaft 25 on the frame 23; Step 4: Simultaneously, the electric slide rail 41 in the second distance adjustment assembly 4 is activated to move the second sleeve shaft 43 on the shaft seat 42, adjust the linear distance of the second sleeve shaft 43 relative to the first sleeve shaft 25, and cause the second sleeve shaft 43 located below the frame 23 and on the support plate 34 to be located in the middle to support the sun gear; Step 5: After adjustment, the hydraulic cylinder unit 21 in the drive assembly 2 is activated to drive the drive frame 22 to rise, thereby driving the first sleeve shaft 25 and the second sleeve shaft 43 to rise, causing the first sleeve shaft 25 and the second sleeve shaft 43 to pass through the wheel exit 5 on the hanger 13 and the test bench 15, and the blocking arm 16, which is movably inserted through the moving opening 6 by the first bolt 17, is moved, causing one end of the blocking arm 16 to be clamped on the first sleeve shaft 25 and the second sleeve shaft 43 used to support the planetary gear; Step 6: The corresponding sun gear and planetary gears can be set on the first sleeve shaft 25 and the second sleeve shaft 43, and finally the combined gear ring is set, and the gears and gears are both supported and limited by the stop arm 16; according to the different gears and gear shaft hole diameters, the corresponding sleeve 44 can be set on the first sleeve shaft 25 and the second sleeve shaft 43, and then the gear assembly processing test is carried out; After the installation is completed, the first motor 24 on the frame 23 can be started to drive the first sleeve shaft 25 to rotate, that is, to drive one of the planetary gears to rotate, and ultimately achieve synchronous rotation of the planetary gears, the sun gear and the ring gear by means of relative meshing transmission, and imaging monitoring is performed through the camera 14 on the hanger 13; After the test, the hydraulic cylinder unit 21 can be activated to retract, driving the drive frame 22 to descend, driving the sun gear and the first sleeve shaft 25 and the second sleeve shaft 43 to descend, so that the planetary gear and the gear ring are blocked and located on the blocking arm 16 to achieve unloading; after rising again, the planetary gear and the gear ring can be installed again for testing; the sun gear can also be replaced.
