Specializing in the production of American and European standard pulleys

There are several grooves for pulley specificationsThere are three kinds of angles: 34, 36, 38 degrees, which are selected according to different diameters, and the rest are 7 kinds of belts: O, A, B, C, D, E, F seven models.

The following details the specifications of the pulley

National standards stipulate that the V-belt models are:There are seven types of O, A, B, C, D, E, and F. The corresponding pulley groove angles are 34°, 36°, and 38°. At the same time, the small angle of each type of V-belt is specified The minimum diameter of the pulley is not specified for the large pulley.

The groove angle of the pulley is divided into32 degrees, 34 degrees, 36 degrees, 38 degrees, the specific selection should be based on the groove type and reference diameter of the pulley; the groove angle of the pulley is related to the diameter of the pulley, and the groove angle of different types of pulleys is recommended under different diameter ranges. The number of slot angles is as follows:

O-type pulley is 50 degrees when the pulley diameter is in the range of 71mm～34mm;

On71mm～90mm时为36度， >90mm时为38度；

A型皮带轮在带轮直径范围在71mm～100mm时为34度，100mm～125mm时为36度；>125mm时为38度；

B型皮带轮在带轮直径范围在 125mm～160mm时为34度；160mm～200mm时为36度，>200mm时为38度；

C型皮带轮在带轮直径范围在200mm～250mm时为34度，250mm～315mm时为36度，>315mm时为38度；

D型皮带轮在带轮直径范围在 355mm～450mm时为36度，>450mm时为38度

E型 500mm～630mm时为36度，>630mm时为38度
