Introduction

V-belt drive is one of the important transmission methods of belt drive. Ordinary and narrow V-belt drives are the most basic forms of V-belt drive. Narrow V-belt drives can be divided into two series. standard width and effective width, and are widely used in machine tools, mining machinery, petroleum machinery, and coal mining machinery. It is used in various fields such as machinery, woodworking machinery, garden machinery, and agricultural machinery. my country issued the national standard for "Ordinary V-belt Pulleys" as early as 1989. The standard was expanded in.2002.The reference width is the standardized basic dimension of the wheel groove and its compatibility with standard and narrow V-belts. The position of the guideline and the reference width determine the pulley groove shape, the pulley reference diameter, and the position of the belt in the groove. Belt drives with standard and narrow V-belt pulleys (based on standard width).

1 Scope

This document specifies the reference width standard V-belt pulleys (types Y, Z, ZX, A, AX, B, BX, C, CX, D, and E) and narrow V-belt pulleys. Wheel groove cross-sectional dimensions, reference diameter series, wheel groove inspection, and wheel material for (SPZ, XPZ, SPA, XPA, SPB, XPB, SPC, and XPC types) Quality, surface roughness, and balance. This document applies to pulleys for single ordinary and narrow V-belts. This document does not apply to pulleys used in banded belts.
