The function of a flexible coupling is to transmit torque from one shaft to another shaft the 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 Flexitech coupling is capable of transmitting high torques at maximum speeds. The flanges are manufactured with cast iron, grade 20. This type of coupling permits drive in direction and requires neither lubrication nor adjustment after fitting. The flexible bushes remain unaffected by water, dust and atmospheric conditions.
Machines which are to be coupled by flexible couplings should first be aligned with all possible accuracy. The capacity of the coupling will then deal with misalignments which occur by reason of temperature variations or heavy shaft loading. Setting of machine foundations or bearing wear will also cause extra loading to be imposed on the coupling. Any or all of these conditions can occur once the machines have been coupled.
Flanges are bored to suit requirements and are keyway to British standard specification, unless otherwise stated. They can also be supplied with the listed minimum bore to permit machining on site.
