Through theoretical derivation and experimental verification, a new method is obtained for further reducing tooth curve error of oblique gear and for choosing feed gear wheel.

The tooth side slack of the gear influences the machining accuracy of NC machine tool directly, so, taking out the slack of feed drive gearing is an important item in the machine tool rebuilding.

In this system the loom physically drives the warp beam through a gear system to feed warp yarns AT a predetermined rATe.
