Problems solved by technology

At present, the synchronous belts on elevators and automatic doors at home and abroad mainly use open polyurethane synchronous belts, but polyurethane synchronous belts have not been recognized by the market because of their shortcomings of poor high temperature resistance and poor bending resistance.
However, domestic open rubber synchronous belts are not recognized by the market because the sides are uneven and the teeth are prone to chipping.

Embodiment Construction

[0023] The best mode for carrying out the present invention will be described below with reference to the appropriate drawings.

[0024] A method for preparing an open synchronous belt, wherein the structure of the linear belt body of the transmission flat belt is: a neoprene outer layer, a glass fiber layer, a neoprene toothed layer, and an elastic nylon cloth covering the toothed layer , the teeth on the neoprene belt tooth layer are arc-shaped teeth; the method includes the following steps:

[0025] Kneading the rubber mixture → beating the kneaded rubber material to the required concentration, so as to impregnate the elastic nylon cloth → cutting → molding the elastic nylon cloth, glass fiber and film on the molding mold , Obtain a shaped strip → vulcanize the shaped strip that is separated from the forming mold to obtain a vulcanized strip → cut the vulcanized strip to obtain an open timing belt with a required width.

Abstract

The invention discloses an open timing belt and a preparation method thereof. A linear belt body of a transmission flat belt is composed of a chloroprene rubber outer layer, a glass fiber layer, a chloroprene rubber belt tooth layer and elastic nylon cloth which coats the belt tooth layer, wherein teeth on the chloroprene rubber belt tooth layer are circular arc-shaped teeth.

Description

technical field [0001] The present invention relates to the field of transmission belts, in particular to an open synchronous belt and a preparation method thereof. Background technique [0002] In recent years, with the continuous improvement of the quality of elevators and automatic doors, more and more automatic door manufacturers have replaced the original gear and chain drives with high-efficiency synchronous belt drives. At present, the timing belts on elevators and automatic doors at home and abroad mainly use open polyurethane timing belts, but polyurethane timing belts have not been recognized by the market because of their shortcomings of poor high temperature resistance and poor bending resistance. However, domestic open rubber synchronous belts are not recognized by the market because the sides are uneven and the teeth are prone to chipping. Contents of the invention [0003] The invention aims to provide an open synchronous belt, which has the characteristics...
