Description
Technical Field

To ensure that the meshing clearance between gears is very small, tooth difference is usually used. When detecting the clearance of the motor gear transmission at present, generally, workers use the feeler gauge method, micrometer method and lead pressing method for detection. Although it can also play a role in detection, through long-term manual detection by workers, it will cause phenomena such as fatigue of the workers, thus affecting the detection effect and detection efficiency.

Two cylinders are symmetrically and fixedly installed on one outer wall of the housing. The same positioning plate is sleeved on the two cylinders. A return spring is sleeved on the two cylinders.

[0007] By adopting the above technical scheme, the motor drives the output shaft of the reducer in the motor complete set of equipment to rotate through the torque sensor. First, it rotates forward, and then it rotates in reverse. And due to the existence of gear clearance, thus during the switching process between forward rotation and reverse rotation, the torque will fluctuate vertically.

[0013] By adopting the above technical solution, the vibration during the use of the housing can be reduced by the dampers and the damping springs, and thus the detection effect can be improved.

[0016] Preferably, the two top plates are respectively located on two sides of a top of the housing, and anti-slip pads are provided on the two top plates.
[0017] By adopting the above technical solution, the friction force can be increased by providing the anti-slip pads.
[0018] Preferably, threaded holes are formed in outer surfaces of one sides of the two telescopic rods, and adjusting bolts are screwed in the two threaded holes.
[0019] By adopting the above technical solution, by pulling the two top plates to move downward, the two top plates move downward and compress the telescopic rods. At this time, the two top plates can be moved to two sides of the top of the housing and the housing can be installed and limited. Then, the corresponding adjusting bolts are rotated to fix and limit the telescopic rods, so that the position of the top plates can be fixed and limited, and thus the stability of the housing can be improved.

[0021] 1. In this application, with the cooperation of a torsion sensor, etc., the motor drives the output shaft of the reducer in the motor complete set of equipment to rotate through the torsion sensor.

[0033] During use, the motor 5 drives the output shaft of the reducer in the complete set of equipment of the motor 5 to rotate through the torque sensor 4. First, it rotates forward, and then it rotates in reverse. And due to the existence of gear clearance, during the switching process of forward rotation and reverse rotation, the torque will vertically fluctuate. Therefore, the torque waveform diagram output by the torque sensor 4 can be used to judge whether the gear clearance is qualified. Furthermore, it is not necessary for the staff to manually detect with tools, which reduces the labor cost of manual work, and can further improve the detection effect and detection efficiency;
[0034] By pulling the pull rod 17 to move, the pull rod 17 moves and drives the positioning plate 12 to move accordingly, and compresses the return spring 15.

At this time, the two top plates 22 can be moved to both sides of the top of the housing 2 to limit the installation of the housing 2, and then the corresponding adjusting bolts 24 are rotated to fix and limit the telescopic rods 21, so as to fix and limit the positions of the top plates 22, thereby improving the stability of the housing 2.
[0039] The implementation principle of the motor gear transmission clearance detection device in the embodiment of the present application is: during use, first place the housing 2 on the mounting plate 7, and then pull the two top plates 22 to move downward. The two top plates 22 move downward and compress the telescopic rods 21. At this time, the two top plates 22 can be moved to both sides of the top of the housing 2 to limit the installation of the housing 2, and then the corresponding adjusting bolts 24 are rotated to fix and limit the telescopic rods 21, so as to fix and limit the positions of the top plates 22, thereby improving the stability of the housing 2;
[0040] When it is necessary to detect the gear clearance in the reducer connected to the output end of the motor 5, the motor 5 drives the output shaft of the reducer in the complete set of equipment of the motor 5 to rotate through the torque sensor 4. First, it rotates forward, and then it rotates in reverse. And because there is a gear clearance, during the switching process of forward rotation and reverse rotation, the torque will vertically fluctuate. Therefore, the torque waveform diagram output by the torque sensor 4 can be used to judge whether the gear clearance is qualified, thereby eliminating the need for workers to manually detect with tools, reducing the labor cost of workers, and further improving the detection effect and detection efficiency;
[0041] Through the damper 8 and the damping spring 9, the vibration during the use of the housing 2 can be reduced, thereby improving the detection effect. And by setting the filter plate 6, dust and other impurities can be blocked and filtered, thereby improving the heat dissipation effect and service life of the electronic devices inside the housing 2. By pulling the pull rod 17 to move, the pull rod 17 moves and drives the positioning plate 12 to move accordingly, and compresses the return spring 15. At this time, the positioning and installation of the connecting plate 11 can be released, so that the filter plate 6 can be disassembled, which is convenient for disassembly, replacement, cleaning and maintenance, and improves the convenience during use.
