Coupling Design

Coupling Design

Flexible Spring Type Coupling with Exclusive Triple Wound Spring Design The Uniflex Coupling is an all steel, single piece coupling that solves a variety of application concerns including: high misalignment, space limitations, high temperature, and exceptionally low backlash/windup. The unique flexing center of the Uniflex consists of three opposingly wound square wire springs for forward or reverse operation. Two steel hubs are then brazed to the steel spring pack to create a durable one-piece flexible coupling.

Notes

Notes

OAL Tolerance + .19 inch. Total backlash is approximately 1/3 of windup at maximum torque – consult Lovejoy Engineering for more information.

This Lovejoy RRU steel coupling hub can be fastened with cap screws to both ends of a Uniflex double flange coupling for connecting rotating shafts and providing low backlash/windup.

The hub has a quick disconnect design to meet drop out requirements.

This hub is made of steel for strength and durability, has a rough stock bore for custom machining, and requires no lubrication.

It is resistant to oil, grease, dirt, and most industrial chemicals and can withstand temperatures up to 250 degrees F.

A keyway prevents the shaft from rotating in the hub.

This hub can be used with couplings suitable for applications such as printing and binding registration, robotics/positioning, conveyors, machine tools, centrifugal pumps, agricultural machinery, blowers, winding machines, and steering mechanisms.

Flexible couplings are used to link two rotating shafts that are not aligned in order to transmit the rotational power, known as torque, from one shaft to the other.

Most flexible couplings consist of two hubs and a middle assembly; each hub attaches to a shaft while the middle assembly flexes between the hubs to accommodate the misalignment of the two shafts.

Shaft misalignments are generally either parallel or angular and cause complications to transmitting rotational power from one shaft to another in the form of stresses, loads, vibrations, and other forces, which vary from one type of misalignment to another.

Flexible couplings are used in a broad range of applications, such as in motor vehicles, conveyors, escalators, agricultural, forestry and mining equipment, aeronautics, robotics and space exploration, among others.

Lovejoy manufactures flexible couplings, universal joints, variable speed drives, and other transmission and mechanical power products.

The company, founded in 1900, is headquartered in Downers Grove, IL.
