The U Type is the basis for all Uniflex couplings. It is a shaft-to-shaft flexible coupling with a simple one-piece design, making it ideal for indexing, robotic, or positioning applications. The U Type consists of a triple-wound flexible steel spring brazed to a steel hub at each end. This all-steel design ensures optimum equipment protection in severe environments and/or high-temperature applications. Regular and short versions are available for most sizes to accommodate different overall length requirements. Special hub or bore modifications are also possible. These units can be supplied with either pinholes or with keyways and set screws. Lovejoy does not recommend the reboring of uniflex couplings by customers due to potential damage to the brazed joint.
This is a durable one-piece flexible coupling for general-purpose shaft-to- shaft applications. It is the basis for all Uniflex coupling types.
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
- Total backlash is approximately 1/3 of windup at maximum torque – consult Lovejoy Engineering for more information.
- OAL Tolerance: + 1/8-in.
