Flexible Jaw Type Couplings

A jaw coupling consists of two metal hubs and an elastomer (spider). The two metal hubs are generally 45-gauge steel, but the aluminum alloy is also used in cases where sensitive loads are required. The elastomeric jaw coupling uses the elastic element placed between the two halves of the coupling hubs to realize the coupling of the two halves of the coupling.

Description

Flexible Jaw Type Couplings

The jaw coupling is a universal power transmission coupling. Design it to transfer torque by connecting two shafts while damping system vibrations and regulating misalignment. Thereby protecting other components from damage. A jaw type coupling consists of three parts: two metal hubs and an elastomeric insert called a jaw coupling element, often referred to as a jaw coupling “spider.” These three parts are pressed together, and the jaws of each hub are mounted alternately with the impeller of the star wheel. Transmit the torque of the flexible jaw coupling through the compressed elastomer lobes.
