Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of detection devices, in particular to a detection device for gear clearance of a gear reducer. Background Art
[0002] The reducer is an independent component consisting of a gear transmission, worm transmission, or gear-worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching the speed and transmitting the torque between the prime mover and the working machine or the actuator. It is widely used in modern machinery. However, in the actual detection process of the gear clearance of most reducers, the tooth clearance detection tooling adopts manual meter detection, which is not only inefficient, but also has errors in accuracy. At the same time, its detection cost is high and needs to be improved. Utility Model Content

[0006] Preferably, the number of the pointers is two groups, and the two groups of pointers are symmetrically distributed on both sides of the connecting block. Here, it is convenient for personnel to observe the gap measurement results.
[0007] Preferably, a rubber pad is fixedly mounted on the surface of the top block, and the top block is located directly below the gear to be tested. Here, the rubber pad can be used to avoid collision between the top block and the gear.
[0008] Preferably, a screw rod is rotatably connected inside the first support rod, a knob is fixedly installed at the end of the screw rod, and a surface of the knob is provided with anti-slip grooves, and a round rod is fixedly installed inside the second support rod. Here, it is convenient for personnel to adjust the connection block so that the top block fits the gear.
[0009] Preferably, the gear to be tested is located between the pressure plate and the limit plate. Here, the rotating rod can be used to drive the gear to be tested to rotate, so as to detect the gap of each tooth of the gear.

By turning the knob, the screw rod is driven to rotate inside the first support rod, and the screw rod is driven inside the slider, so that the slider slides inside the first support rod. At the same time, the slider slides inside the second support rod using the round rod, and the slider drives the connecting block to move on the sides of the first support rod and the second support rod. Then the connecting block drives the pointer to move on the scale line, which can facilitate personnel to observe using the scale line. When the top block fits with the gear under the action of the connecting block, the gear gap can be detected. The two sets of pointers can facilitate personnel to observe the gap measurement results, avoiding the situation where the slider is offset during the sliding process, resulting in inaccurate detection results.
[0013] 2. In the utility model, by setting a pressure plate, a limit plate, an insert block, and a socket structure, the gear to be tested is placed on the limit plate, so that the insert block is inserted into the socket, and the pressure plate presses the gear to be tested between the pressure plate and the limit plate under the action of the cylinder, so that the gear to be tested can rotate with the rotating rod, and the gap of each tooth of the gear can be detected, which is convenient for personnel to use and avoids the need for personnel to disassemble and assemble the gear to be tested multiple times to adjust the position of the gear to be tested.
