Coupling

In pump design, a spacer coupling is a cylindrical shaped piece introduced between the pump shaft coupling hub and motor shaft coupling hub. It gives enough space to remove the pump mechanical seal when doing maintenance, without moving either the pump body or the driver.

he 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.

The rigid shaft couplings are completely interchangeable to other industry standard rigid couplings. Raydafon offers these as a rigid single piece set screw clamp design, a one-piece single split clamp design, and a two-piece double split clamp design.

our couplings consist of 3 separate parts. Each set includes two coupling halves and one flexible insert (also known as a "spider"). Each coupling half can have either the same shaft size or two different shaft sizes.

Gear flexible coupling are typically the flexible mechanical devices which are used for total power transmission. They in fact use a hub with gear teeth on the outer diameter of the input shaft.

Flexible couplings are used to transmit torque from one shaft to another when the two shafts are slightly misaligned. Flexible couplings can accommodate varying degrees of misalignment up to 3° and some parallel misalignment.
