Noise generated by pulleys is also related to the dimensional accuracy of the pulley, which determines the smoothness of meshing between belt teeth and pulley grooves.

Lifetime lubricated ball bearing and high temperature grease and seals assure peak bearing performance. These elements working together all provide the smooth, quiet drive service that both …

Principles and Definitions There are three typ. s of basic pulley systems. They are the 2:1, the Z-rig, and block and tackle (Figure 1; see also Figure 7. Figure 8, and Figure 12). Most systems described in …

Pulley configuration should be selected based on application load requirements, environmental conditions, the pulley position in the conveyor system (head/drive, tail, bend, etc.) as well as the …

In this system, the amount of force that must be applied to lift the object is equal to the weight of the object. The pulley systems labeled 2 and 3 below are compound pulley systems that use a …

Pulley systems do not have to be assembled as accurately as geared systems but they are also subject to the belts slipping which can affect reliability of the system.

The martin engineered class pulley (ECP) line is not limited to just high tonnage and extreme applications. This class of pulley can be used effectively in every industry to ensure optimum …
