For any manufacturing enterprise, processing and inspection work are essential, which are also necessary requirements to ensure product quality. For the inspection of precision gears, it also needs to pass strict inspection before leaving the factory. During the test, its main test items include motion accuracy, basic accuracy, backlash and working stability.
The inspection item of the contact accuracy is to look at the tolerance of the tooth direction. After roughly passing through the cylinder, look at the allowable error and the motion accuracy. This is one of its basic inspection items, and it can also guarantee normal operation. For the test items of backlash, it is mainly to see that the difference value is greater than the actual common normal length. This is a standard that guarantees side clearance.
The actual distance between the two parallel tangents measured by the adjacent ruler of the same name of the precision gear, and the possible tolerance. Of course, it is still a relatively simple project, and it is selected according to different project points, as well as equipment and production scale. Except for small batch production, the main inspection is the above. For mass production, it is mainly to do a comprehensive inspection. If the normal inspection of precision gear work can be guaranteed, it can be used by the market.
The above is an introduction to how to do inspection work in precision gear processing.
