Embodiment Construction

[0011] See attached Figure 1~3 , a low-noise belt transmission device, including a driving shaft (1) and a driven shaft (3), the driving shaft (1) is provided with a driving pulley (2), and the driven shaft (3) is provided with a slave The driving pulley (4), the driving pulley (2) and the driven pulley (4) are all composed of a fixed half-wheel (2a, 4a) and a movable half-wheel (2b, 4b) which are divided into two parts, The four half-wheels are all in the shape of a top, with the same size and taper. The end faces are flat and have flanges, and the holes in the center are respectively pierced on the shafts (1, 3). The cones face each other, but the positions (a, b) Interchange and form the pulley groove (6), the fixed half-wheels (2a, 4a) rotate together with the shaft, and the movable half-wheels (2b, 4b) can move. The purpose of the above-mentioned technical measures is to change the belt pulley groove from the traditional fixed structure to a half-fixed, half-movable tra...

Abstract

The invention discloses a low-noise belt transmission device. The low-noise belt transmission device comprises a driving shaft (1), a driving belt wheel (2), a drive shaft (3), a driven belt wheel (4), a V-shaped belt (5) and two belt wheel grooves (6), wherein the driving belt wheel (2) consists of a fixed half wheel (2a) and a movable half wheel (2b); the driven belt wheel (4) consists of a fixed half wheel (4a) and a movable half wheel (4b); a fixed half wheel (a) and a movable half wheel (b) are just in contact with each of two sides of the V-shaped belt (5). According to the low-noise belt transmission device, the friction force of the belt and the wheel grooves is alleviated by separating the assemble mode of the transmission belt wheel grooves (6); the noiseless property of the belt transmission device is improved; meanwhile, the surface roughness of the belt wheel grooves is set between 0.5 micron and 3.0 microns; the operation noise is lowered by reasonable reduction of the friction coefficient of the belt and the wheel grooves.

Description

technical field [0001] The invention belongs to the technical field of new mechanical products, and relates to a mechanical transmission device, in particular to a low-noise belt transmission device. Background technique [0002] In the existing belt transmission device, the running noise generated when the belt contacts the surface of the pulley groove is ubiquitous, especially in the heavy-duty transmission device, the noise generated is surprisingly large, which seriously pollutes the working environment. [0003] The invention mainly changes the complete and fixed pulley groove in the belt transmission device into a separate and variable speed pulley groove, and reduces the generation of noise by reducing the energy generated by the friction between the belt and the pulley groove during heavy-duty transmission. At the same time, setting a reasonable surface roughness for the variable speed pulley groove can also effectively reduce noise. Contents of the invention [0...
