Title:
BELT PRESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/218767
Kind Code:
A1
Abstract:
Disclosed in the utility model is a belt pressing device, characterized in comprising a belt wheel in contact with an inner side face of a belt, and a pressing wheel in contact with an outer side face of the belt; the pressing wheel is connected to a pressing and loosening structure, such that when the belt moves in the direction from the belt wheel to the pressing wheel, the pressing wheel approaches close to the belt wheel, and when the belt moves in the direction from the pressing wheel to the belt wheel, the pressing wheel moves far away from the belt wheel. The device of the present utility model is mainly applied to belt pressing in a cyclic reciprocating unidirectional transmission system. When the belt drives the belt wheel to move forward, the belt is pressed against the belt wheel, such that the belt is not easy to slip relative to the belt wheel, and can transfer a large moment, and when the belt wheel moves in reverse, the belt is kept loose, thereby reducing the resistance.
