Title:
CONSTANT TENSION HOLDING DEVICE FOR FLAT BELT IN FLAT BELT DEVICE
Document Type and Number:
Japanese Patent JPH04107350
Kind Code:
A
Abstract:

PURPOSE: To hold the tension of a flat belt having a long belt length at a constant value by providing a cylinder for controlling a tension to continuously exert a constant tension or press force on a slider member to which a tension sleeve is attached and a detent device to prevent the return of the slider member.

CONSTITUTION: A plate 21 is integrally attached to a base 11 in which a slider 12 is fitted, a bracket 22 is mounted on the plate 21, and a cylinder 23 for controlling a tension is attached to the bracket 22. Structure wherein elongation with time of a flat belt 2 is absorbed by means of the air pressure or the oil pressure of the cylinder 23 for controlling a tension is provided and structure wherein a tension pulley 6 is prevented from return in a direction in which a belt tension is reduced by means of detent devices 27 and 28 is provided. This constitution automatically hold the tension of the flat belt 2 at a constant value even when a belt length is long and elongation with time is high.
