Features

Features

Versus Traditional Keyed Connections No Backlash due to fit tolerances No impact effect from reversing loads Ability to adjust axial position and angular timing No fretting corrosion due to movement at the fit interface Versus Traditional Interference Fits Easier and quicker to install Higher contact pressures can transmit greater torques Easy and quick to remove without damaging the shaft or hub – even after years of service Design Benefits Eliminate cost of machining keyways or splines Reduce the shaft stress by removing keyways or splines Eliminating keyways often allows the use of a smaller diameter shaft Can place anywhere on shaft, and allows for easy angular timing Easy removal without damaging the shaft or hub means easier maintenance for your customer

Lovejoy 1750 Series Shaft Locking Device 1-15/16 In shaft diameter

 

This Lovejoy SLD 1750 Series internal shaft locking device connects a hub to a shaft in power transmission applications.

Screw tension is converted into radial pressure to create an interference fit for zero backlash and high contact pressure for transmitting greater torque. It is self-centering for even, concentric tightening.

It expands to fill the gap between shaft and hub for easy installation and removal, and the friction fit eliminates damage to the shaft caused by hub movement.

This high-torque shaft locking device is suitable for use with compressors, conveyors, flywheels, gearboxes, reducers, and mixer shafts, among others.

Shaft collars are ring-shaped devices primarily used to secure components onto shafts. They also serve as locators, mechanical stops, and spacers between other components.

The two basic types of shaft collars are clamping (or split) collars, which come in one- or two-piece designs, and setscrew collars. In both types, one or more screws hold the collars in place on the shaft.

In setscrew collars, screws are tightened through the collar until they press directly against the shaft, and in clamping collars, screws are tightened to uniformly compress the collar around the shaft without impinging or marring it.

Whereas setscrew collars and one-piece clamping collars must be installed by sliding the collar over the end of the shaft, two-piece clamping collars separate into two halves and can be installed between components on the shaft.

Shaft collars are made from a wide range of materials including zinc-plated steel, aluminum, nylon, and neoprene.

Found in nearly every type of machinery and industry, shaft collars are used in applications including gearbox assemblies, motor bases, machine tools, drive shafts, agricultural implements, medical equipment, and paper and steel mill equipment.

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.
