The function of a flexible coupling is to transmit the torque from one shaft to another in cases where limited misalignment may occur and also to absorb shock loads.
ESCO straight 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, which can transmit the high torque at maximum speed and permits drive in either direction and requires neither lubrication not adjustment after fitting. The flexible bushes remain unaffected by water, dust and atmospheric condition.
