Oscillating drive-transmission device for the workpiece feed rollers of woodworking machinery.

摘要

The invention envisages a speed reduction unit (1) which can oscillate by rotating around a horizontal axis lying parallel to the axis of a contact roller (6) keyed to the output shaft (4) of the reduction unit (1) itself. Unlike conventional machine feed drives of the same general type in which a fixed reduction unit drives the roller by way of an unwieldy drive shaft incorporating large universal joints, the drive-transmission set forth herein eliminates the problem of excessive strain on such drive-components by adopting a much simpler arrangement. The device as embodied herein avoids any transmitting of unwanted vibrations to the contact roller (6).
