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. They 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. The effective width is the basic dimension describing the pulley groove, and the effective diameter of the pulley is the... The basic diameter of the pulley. my country issued the national standard for "Narrow V-belt Pulleys" as early as 1989, and expanded the standard in.2002.(There are...) The effective diameter series is selected from the preferred number series R20 in GB/T 321-2005.When this is insufficient, it can be supplemented by the R40 and R10 series. For charging, the R10 series is highly recommended. The difference between metric and imperial dimensions is allowed within a tolerance range of 0% to 1.6%. This allows for the selection of dimensions to cover a wide range of needs. The maximum effective diameter can be increased to the following dimensions based on the basic diameter. 12.8 mm for 9 N/J, and [the maximum increase is not specified] for 15 N/J. Up to 28.8mm, 25N/J plus 1.6%. Since only positive deviation is required, the minimum effective diameter is equal to the basic effective diameter. Belt drive narrow V-belt pulley (effective width system)

1 Scope

This document specifies the effective width of narrow V-belt pulleys (9N, 9NX, 9J, 9JX, 15N, 15NX, 15J, 15JX and 25N, 25J types). Groove cross-sectional dimensions, effective diameter series, wheel groove inspection, pulley material, surface roughness, and balance. The standard groove type in this document applies to pulleys for single and multi-strand narrow V-belts. Deep groove pulleys are not suitable for multi-strand V-belts and are primarily used for offset applications. (Twisting, misalignment) drive, such as 1/4 circle drive or vertical shaft drive.
