Title:
V BELT
Document Type and Number:
Japanese Patent JPS62237137
Kind Code:
A
Abstract:
PURPOSE:To make possible high-load transmission with longevity and low noise by forming the pulley contact faces, at least, of the blocks out of hard resin material mixed with organically reinforced fiber and containing a friction- regulating drug. CONSTITUTION:A V-belt 1 is made up of pair of heavy-duty endless belts 2, 3 and V-blocks 4 is engagingly locked at a fixed pitch longitudinally. Each block 4 is formed on its side with an opening engagement groove, the upper and lower faces of which are formed with a projecting portion 6 in angle-shape in cross-section and a curved projecting face 7. Also, the pulley contact faces, at least, V-blocks 4 are formed out of high rigidity material using organic fiber, such as nylon, polyester, aramid, vinylon and the like. And as a friction- regulating drug to be contained in said material is used Teflon powder, which lowers statical friction coefficient between the pulley material and blocks 4 and does not lower dynamical friction coefficient much and does not harm transmission capacity and lowers noise. Accordingly, high-load transmission with longevity and low noise is possible.
