KR950023877A - Tension control device of power transmission member - Google Patents

Abstract

The present invention relates to a device that can adjust the tension of the belt, chain, and the like. In particular, the present invention relates to a device capable of adjusting the tension of a power transmission member such as a belt or a chain by supporting the eccentric shaft member in a rotatable position and rotating the predetermined angle to adjust a distance from the other driving part or driven part. It is convenient to use because the tension of the power transmission member can be adjusted simply by rotating the eccentric shaft member at a predetermined angle. In addition, since the power loss and the shortening of the belt life are not caused by the tension adjusting device, the tension adjusting device using a conventional roller is used. More efficient.
