Problems solved by technology

At present, the commonly used tensioning methods mainly include self-weight tensioning, heavy hammer tensioning, and regular tensioning, etc., but the exposed structure is not compact, takes up a large space, is inconvenient to adjust, and has poor adjustment accuracy.
Regular tensioning needs to be carried out on a regular basis, which increases the labor intensity of employees; if the self-weight tensioning and heavy hammer tensioning are not tensioned in time, the transmission capacity will be reduced, which will inevitably bring hidden dangers to the equipment
This not only reduces the absorption capacity of the motor to load changes and causes frequent failures, which affects the overall operation rate of the equipment, but also because of the short life of the belt, the number of replacements increases and the cost of spare parts increases

Abstract

The invention relates to a belt tensioning device. The belt tensioning device comprises a tensioning base and two motor movement limiting mechanisms symmetrically arranged on the tensioning base. Each motor movement limiting mechanism comprises a vertical two-hole plate, a vertical single-hole plate and a tensioning sliding block. Each tensioning sliding block is located in a corresponding sliding groove, one end of the sliding groove is connected with the corresponding vertical two-hole plate, and the other end of the sliding groove is connected with the corresponding vertical single-hole plate. Compared with the prior art, the belt tensioning device has the characteristics of being high in adjusting precision, accurate in tensioning degree, capable of decreasing tension number of times, free of periodical tensioning operation and capable of prolonging the service life of a belt, decreasing replacing number of times and lowering spare part cost.

Description

technical field [0001] The invention relates to the field of equipment transmission, in particular to a belt tensioning device. Background technique [0002] Belt drive is a kind of mechanical transmission that utilizes a flexible belt tensioned on a pulley for motion or power transmission. Belt transmission has the characteristics of simple structure, stable transmission, ability to buffer and absorb vibration, and can transmit power between large shaft distances and multiple shafts. It is also low in cost, does not require lubrication, and is easy to maintain. According to different transmission principles, there are friction belt drives that rely on the friction between the belt and the pulley, and there are synchronous belt drives that rely on the teeth on the belt and the pulley to mesh with each other. [0003] After the belt transmission works for a period of time, it will relax due to the plastic deformation of the flexible belt, which will reduce the initial tensio...
