project overview

Dynagrip Dual Duty Pulleys are equipped with 'Easy-Grip' taper bushes to achieve easy mounting and to eliminate reboring of pulleys. Easy-Grip bushes accommodate a wide range of tolerance variations found in commercial shaftings. The construction of 'Easy-Grip' is such that even an unskilled worker can mount the pulleys on to the bushes just with the help of anAllen wrench.

Grooves for the Dynagrip Dual Duty Pulleys conform to I.S. Specifications (I.S.3142:1993) and are suitable for both the conventional A, B, C, section Vbelts and wedge belts. Increased sheave strength for higher capacity is obtained through adequate changes in design to utilize the full benefits of modern improvements in belt.

Dual Duty Pulleys are made from high quality cast iron and are machined to fine limits, and are balanced statically wherever necessary. Dynamically balanced pulleys are also available at extra cost. About 300 sizes of standard pulleys made it possible to select the drives within ± 1.5% of required speeds with a maximum speed ratio of 1:7.

Normally, keyways are suitable for rectangular parallel keys as per I.S. 2048 1975. Some bushes can accommodate slightly larger shafts using thinner keys. Details are on Page 7.

It should be noted that life of belts and pulleys not only depend on quality but also on proper drive selection. Drive design facilities are also available without any obligation
