Abstract

The invention discloses a V-shaped belt wheel and aims at solving the defects that the existing V-shaped belt wheel is easy to wear and short in service life, and the defects of a small friction coefficient of the friction drive side of a belt slot and a belt, small drive force and high manufacturing cost of the belt wheel. The V-shaped belt wheel comprises a belt wheel main body, wherein the belt wheel main body is connected with a wheel sheet; the wheel sheet comprises outer wheel sheets and an inner wheel sheet; one outer wheel sheet is respectively arranged at two ends of the belt wheel main body; an annular connecting sheet and the annular inner wheel sheet are coaxially and alternatively arranged between the two outer wheel sheets; the diameter of the connecting sheet is smaller than that of the inner wheel sheet; the outer wheel sheets, the connecting sheet and the inner wheel sheet are fixedly connected through a connecting structure; coarse friction layers are arranged at the opposite end faces of the adjacent wheel sheets; a V-shaped belt slot is formed between two adjacent wheel sheets and the connecting sheet between the two adjacent wheel sheets; the end faces of the two adjacent wheel sheets form the side of the belt slot in friction drive, and the side of the belt slot is an inclined plane.

Description

technical field [0001] The invention relates to a pulley, more specifically, to a V-shaped pulley with convenient installation, long service life and high transmission efficiency. Background technique [0002] In the prior art, force is generally transmitted between the V-shaped transmission belt and the pulley through sliding friction. In actual use engineering, the belt will undergo certain elongation and deformation. When the smaller driving pulley drives the larger driven pulley, the wrap angle of the large pulley is larger than that of the small pulley, so that the belt is easy to The phenomenon of slipping occurs on the small pulley, especially under the working conditions of high power and heavy load, the slipping phenomenon is more obvious. In order to overcome the slipping phenomenon, people have designed a V-belt transmission system with meshing transmission. This pulley includes a pulley body with a groove. The pulley body is made of gray cast iron, while the co...
