Shaft locking devices for rigid shaft connections with high alignment accuracy

Ameriloc internal and external locking devices and shaft couplings are custom-engineered, manufactured, and tested to precise tolerances to meet specific customer requirements and provide years of trouble-free service.

Quality materials and state-of-the-art manufacturing processes ensure high reliability. Units eliminate the need for keyways, splines, or hydraulic hubs, allowing for unlimited shaft positioning. Installation and removal is easy using standard tools. Features include zero backlash, reduced shaft stress, and high contact pressure for greater torque. Tight contact prevents contamination in high dust and moisture environments.

Ameriloc locking devices are suited for use on test stands, printing presses, ski lifts, mining crushers, meat processing, drilling, milling, compressors, pulp & paper, cranes, fans, and steel mills.

All units are pre-assembled, ready to install. Torque range is from 25,000 to 4,303,675 ft-lb (34 to 5,835 kNm). A range of standard sizes is available with outer diameters from 12.5 to 53 in. (320 to 1,350 mm), and shaft diameters from 6.5 to 29.5 in. (165 to 750 mm). Additional sizes and custom designs are available upon request.

Candy Coup-link Line of Zero Backlash Flexible Shaft Couplings

Coup-Link is a full line of zero backlash flexible shaft couplings including Beam, Bellows, Jaw, Disc and Oldham.  All are available in a variety of mounting options including set screw, keyway, clamp, conical and shrink disc configurations.

Beam, Disc, Jaw, Bellow, Encoder and Oldham couplings

Motors, reducers, encoders, shafts and other rigid elements often fail prematurely. Many times this is from misalignment, which often leads to bearing, shaft or seal failure. Zero backlash, flexible shaft couplings  accommodate parallel and angular misalignment and shaft endplay.

Properly selecting a Candy Coup-Link provides the flexibility to handle many types of misalignment and may offset problems such as minor design errors or improper assembly.

Floating Shaft Couplings Span Long Distances

Floating Shaft CD® Couplings are a torsionally stiff, no backlash option for connecting long distances between shaft ends. They can often be a zero-backlash alternative to Cardan Shafts. The flex element made of composite material makes it possible to have zero-backlash, high torsional stiffness and low bearing loads simultaneously.

The composite material is flexible in one plane and stiff in another plane. It is not prone to fatigue and will perform longer than stainless steel. Custom designs are available with torque ranges from 270 in.-lbs (30 Nm) to 550,000 in.-lbs (63,000 Nm) and with speed ranges from 500 rpm to 15,000 rpm. They are available in custom lengths from 46 in. to 196 in. and with outside hub diameters of 2.25 to 12 in.

Things to Consider When Choosing Flexible Shaft Couplings

T.E.A Transmissions says machine designers should consider torsional stiffness, backlash, torque and attachment style when looking to specify flexible shaft couplings.

According to T.E.A Transmissions, its bellows couplings have high torsional stiffness and can be used in any drive system where high levels of motion integrity are essential.

The company says bellow couplings are backlash free and capable of speeds up to 10,000Rpm.

T.E.A Transmission claims helix couplings are manufactured as one piece therefore achieving its flexibility in angular, radial and axial modes. The couplings are capable of speeds up to 8000Rpm.

Bellows and helix couplings are typically used for encoder drives in closed-loop servo system applications.
