Before the slewing bearing leaves the factory, the tooth jump detection is an important step to ensure its transmission accuracy. In the picture, the inspector is detecting the highest point of tooth jump on the gear ring. The so-called tooth jump refers to the amount of runout of the gear teeth along the tooth top circle, which directly affects the smoothness of gear meshing and the noise of operation. If the tooth jump exceeds the standard range, it will affect the reliability of the entire machine transmission and even cause early damage.
