DriveChainThe error will affect the correctness of the tool movement, and in some cases, it is the main factor affecting the machining accuracy. For example, when hobbing a gear, the ratio of the rotation speed of the hob to the rotation speed of the workpiece is required to be constant and maintain a strict motion relationship.
When the transmission components in the transmission chain (such as hobbing wheel, indexing worm gear pair, etc.) have manufacturing errors and assembly errors, as well as wear during use, the correct movement relationship will be destroyed and the gear will be rolled out. Errors (such as circumferential error, circumferential cumulative error and tooth profile error, etc.). Therefore, the transmission accuracy of the machine tool transmission chain depends first on the manufacturing and assembly accuracy of each transmission element, and secondly on the position of each transmission element in the transmission chain.
