Flat belt pulleys for taper bushings

General information

The pulleys can be used with all types of belt designs. The nominal width of the pulley and belt must be approximately the same to ensure proper drive. When assembling the pulleys, special care must be taken to ensure that the pulleys are parallel and the axes are at an angle to each other, as the belts tend to "walk" on the pulley. If installed improperly, the belt will constantly fall off the pulley. Pulleys come in two different designs.

Traditionally, the rimless versions are used. These pulleys have a curved housing, the so-called barrel shape. This design is necessary to prevent the belt from "climbing" sideways during rotation and falling off the pulley. Due to the drum shape, the belt is under greater tension in the center of the pulley and therefore has difficulty moving sideways. In some applications flanges are used with a flange. The flanges on both sides of the pulley prevent the belt from falling off the pulley. Flanged pulleys generally have a cylindrical housing.

A taper bushing is required to secure the clamped pulleys to the shaft. Without a taper bushing, the pulley cannot be mounted on the shaft. The taper bushing is not an accessory for the clamping disc and must be purchased separately. The taper bushings are available in the tensioning elements group of the keilriemen.at webshop. The type of taper bushing specified in the pulley part number and size must be selected for the pulley with the appropriate hole for the shaft size to be used.
