Bush Type Flexible Couplings • Simple & compact in construction • Transmits torque through high tensile steel bolts • 26 sizes-power rating from 0.81 kW to 2069 kW at 100 rpm The function of a flexible coupling is to transmit torque from one shaft to another in cases where limited misalignment may occur and also to absorb shock loads. The Fenner Bush Type Flexible Coupling of the cushioned drive type, transmits the torque through high tensile steel bolts to the machine input shaft. Highly developed rubber compounds are used in bushes to absorb shock loads, torsional vibrations and slight misalignments. Simple and compact in construction, the Fenner Coupling is capable of transmitting high torques at maximum speeds. The flanges are manufactured with cast iron, grade 20 of IS. 210. This type of coupling permits drive in either direction and requires neither lubrication nor adjustment after fitting.The flexible bushes remain unaffected by water. dust and atmospheric conditions.
