Pulley Taper Bush

Pulley taper bush:

SST machinery pulley taper bush are widely used together with sprockets, v-belt pulleys, timing pulleys, coupling and other mechanical parts with taper bore connections.

Taper bushing series are made of high quality engineered materials with great tolerance.

The feature is easy to use and needs no additional alteration. These bushings can suit almost all kinds of assemblies and sizes. They are the best choice in design for mechanical connections.

To complete designations add bore size.

No costly re-boring: full range of both metric and imperial available.

Standard range fits up to 125mm/5" shafts & Hub diameter required depends on the application.

Complete short reach range available, for compact lightweight assemblies & Clean, Compact Design.

Ease of installation and removal.

Disassemble for pulley taper bush:

1. Loosen all bolts, take out one or two bolts according to the number of disassembly holes, lubricate the bolt pattern and bolt tip with oil, and insert the bolts into the disassembly holes shown in the following figure.

2. Tighten the bolts alternately until the taper sleeve and pulley are loosened.

3. Take out the taper sleeve and belt pulley from the shaft.

When the taper sleeve connects the belt pulley with the shaft, an interference fit connector is formed. The inner hole of the taper sleeve is connected with the shaft with a key, and the torque and force are transmitted through the key. Although there is no key connection between the taper sleeve and the belt pulley, there is positive pressure on the joint surface, and the friction generated can transmit torque and force.

The advantages of pulley drive are:

The belt pulley transmits energy to mitigate load impact

The belt pulley drive operates stably, with low noise and vibration

The structure of pulley drive is simple and easy to adjust

The manufacturing and installation accuracy of pulley drive is not as strict as that of meshing drive

The belt pulley drive has the function of overload protection

The adjustment range of the center distance between the two shafts of the belt pulley drive is large
