Description

Technical Field

[0001] The utility model relates to the technical field of flexible pulley performance testing, in particular to a speed reducer rigid flexible pulley performance testing device. Background Art

[0002] The flexspline is a key component in a harmonic reducer. It is a flexible, thin-walled, annular structure typically with external teeth. It is designed to engage with the rigid wheel through elastic deformation, thereby achieving the reducer's transmission. The flexspline is subject to continuous deformation and friction during reducer operation, so wear resistance testing is required during production to ensure its long-term reliability and durability.

[0003] Although traditional reducer rigid flexspline performance testing devices can test the wear resistance of flexsplines by wearing them, the test part of the flexspline is usually the outer teeth of the flexspline. The outer teeth of flexsplines of different specifications have different heights, and the wear structure position of the testing device is usually fixed. This makes it difficult for the testing device to adapt to outer teeth of different heights, thus affecting the accuracy and consistency of the test.

[0004] Therefore, a speed reducer rigid flexible pulley performance testing device is particularly needed to solve the problems existing in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0025] Example: A device for testing the performance of a rigid flexible wheel of a speed reducer, see Figure 1-Figure 2 and Figure 4-Figure 7As shown, it includes a test bench 1, a motor 2, a driving shaft 3, a limit block 301, a knob 4, a sleeve 5, a guide rod 501, an electric slide rail 6, an electric slider 601, a screw 7, an adjusting rod 8, a grinding wheel 9, a fixing frame 10, a gear ring 11, a protective cover 15, a visual window 16 and a controller 17. The bottom of the four legs of the test bench 1 are all provided with anti-slip pads to improve stability. The motor 2 is connected to the left position in the middle of the upper part of the test bench 1 by bolts. The driving shaft 3 is connected to the output shaft of the motor 2 through a coupling. The upper end of the driving shaft 3 is connected to the limit block 301 by welding. The electric slide rail 6 distributed front and back is connected to the right side of the upper part of the test bench 1 by bolts. The electric slider 601 is slidably connected to the outside of the electric slide rail 6. The two electric sliders 601 are connected by bolts with a sleeve 5. The sleeve 5 is connected to the symmetrically distributed guide rods 501 by welding. The adjusting rod 8 is dynamically connected, and the screw 7 is rotatably connected inside the sleeve 5. The adjusting rod 8 is threadedly connected to the screw 7. The lower end of the screw 7 is connected to the knob 4 for assisting rotation by welding. The upper end of the adjusting rod 8 is rotatably connected to the grinding wheel 9. A gear ring 11 is placed on the outside of the grinding wheel 9, and a cross-structured fixing frame 10 is connected to the top by bolts. The four protrusions of the fixing frame 10 simultaneously press against the gear ring 11, so that the gear ring 11 is fixed to the outside of the grinding wheel 9, and the contact surface between the protrusion and the gear ring 11 is provided with an anti-slip pad to enhance the fixing effect and prevent the fixing frame 10 from wearing the gear ring 11. The rear side of the upper part of the test bench 1 is rotatably connected to the protective cover 15, which completely covers the table top of the test bench 1. The front side of the protective cover 15 is embedded with a visual window 16 for viewing the situation. The middle position of the upper front side of the test bench 1 is connected to the controller 17 by bolts. The controller 17 is electrically connected to the motor 2, the electric slide rail 6 and the electric slider 601.

[0026] See Figure 2 and Figure 3 As shown, it also includes a collection box 12, a connecting block I 13 and a connecting block II 14. Two collection boxes 12 are placed on the upper part of the test bench 1. The two collection boxes 12 cooperate to encircle the outside of the driving shaft 3. The front and rear sides of the left collection box 12 are connected to the connecting block I 13 by welding, and the front and rear sides of the right collection box 12 are connected to the connecting block II 14 by welding. The connecting block II 14 is clamped with the adjacent connecting block I 13 to fix the two collection boxes 12 together.

[0027] First, the staff rotates the protective cover 15 upward by 180 degrees to expose the table surface of the test bench 1, then starts the electric slide 6 through the controller 17, and controls the electric slider 601 to drive the sleeve 5 to move to the right to the appropriate position, thereby widening the distance between the adjusting rod 8 and the driving shaft 3, and then clamps the flexible wheel to be tested on the upper end of the driving shaft 3. The limit block 301 plays a limiting role, assisting the staff to quickly clamp the flexible wheel. Then, pinch the knob 4 and turn or reverse the screw 7 by hand to drive the adjusting rod 8 to drive the grinding wheel 9 to move up and down to the appropriate height, so that the ring gear 11 is aligned with the outer teeth of the flexible wheel. After the alignment is completed, control the electric slider 601 to drive the sleeve 5 to move to the left to the appropriate position so that the ring gear 11 contacts the outer teeth of the flexible wheel, and close the electric slide 6, and then rotate the protective cover 15 downward by 180 degrees to cover the table surface of the test bench 1, and then start the motor 2. The output shaft of the motor 2 drives the driving shaft 3 to rotate, and the driving shaft 3 drives the flexible wheel to rotate, so that the outer teeth friction gear of the flexible wheel is tested for wear resistance, and the debris generated during friction falls into the two collection boxes 1 2, improve the cleanliness of the test bench 1. During the test, the protective cover 15 separates the flexible pulley and the ring gear 11 from the outside world to prevent the staff from accidentally touching the flexible pulley and the ring gear 11 and getting hurt. The staff can check the test status of the flexible pulley through the visual window 16. After the test is completed, turn off the motor 2, repeat the above steps to expose the test bench 1, and pull the distance between the adjusting rod 8 and the driving shaft 3, remove the flexible pulley that has completed the test from the driving shaft 3, and finally pull the right collection box 12 upward to offset the left collection box 12, so that the connecting block II 14 and the connecting block I 13 are disengaged, and the debris in the two collection boxes 12 is poured out. After pouring out, reverse the above steps and fix the two collection boxes 12 together to circle the outside of the driving shaft 3. It is worth noting that the staff can replace the ring gear 11 of different thickness according to the wear resistance test requirements of the flexible pulley. The replacement steps are as follows: remove the fixing frame 10 from the grinding wheel 9, take out the original ring gear 11, and put on the appropriate ring gear 11 to complete the replacement of the ring gear 11 to meet the test requirements of the flexible pulley.
