Embodiment Construction

[0024] In the prior art, synchronous toothed belts are generally divided into trapezoidal toothed synchronous belts and circular arc toothed synchronous belts. for high speed transmission. The tooth shape of the arc-toothed synchronous belt is curved, so that the tooth height, tooth root thickness and tooth root fillet radius are larger, and the stress distribution state is better after loading, so as to avoid excessive concentration of tooth root stress and increase the tooth root The load level of the circular arc tooth synchronous belt is better, and the service life is longer. The teeth in the tooth layer of the trapezoidal tooth synchronous belt and the arc tooth synchronous belt are arranged on a plane, and the tooth grooves in the toothed pulley are arranged on a cylindrical surface, which can only be used for transmission with parallel axes. In the synchronous toothed rope and the synchronous toothed sheave of the present invention, the teeth arranged on the plane are...

Abstract

The invention relates to a transmission device, in particular to a synchronous tooth-shaped rope transmission device. The device comprises a synchronous tooth-shaped rope and a synchronous tooth-shaped rope wheel, the synchronous tooth-shaped rope comprises a rope body and a belt tooth layer, the synchronous tooth-shaped rope wheel comprises a belt wheel body and tooth grooves formed in the belt wheel body, the belt tooth layer is a cylindrical surface, closed annular teeth are arranged on the inner circumferential surface of the cylindrical surface belt tooth layer at equal intervals, cylindrical surface grooves are formed in the outer circumferential surface of the belt wheel body of the synchronous toothed rope wheel, and arc-shaped teeth are arranged on the cylindrical surface groovesat equal intervals. The synchronous tooth-shaped rope transmission device has the traditional advantages of a traditional synchronous toothed belt, such as accurate transmission ratio, stable transmission, high transmission efficiency and the like, and also has the advantages of realization of transmission and speed change of axes at any angle, larger transmission power, long transmission distanceand the like.

Description

technical field [0001] The invention relates to a transmission device, in particular to a synchronous toothed rope transmission device, which is used in precision transmission, drive, speed change and other occasions. Background technique [0002] In industrial applications, synchronous belt transmission is composed of an endless belt with equally spaced teeth on the surface and meshing wheels. It combines the advantages of belt transmission, chain transmission and gear transmission. When turning, the power is transmitted by meshing the teeth with the tooth grooves of the wheel. Synchronous belt drive for transmission has accurate transmission ratio, no slip, can obtain constant speed ratio, stable transmission, can absorb vibration, low noise, wide range of transmission ratio, transmission power from several watts to hundreds of kilowatts. High transmission efficiency, compact structure, suitable for multi-axis transmission, no lubrication, no pollution, widely used in var...
