Shaft coupling can double as a machined
spring

Abssac is well known for supplying the Heli-Cal beam style shaft coupling, but it is not widely known that the same product can be utilised as a machined spring.

Machined Wrap Spring Clutch Abssac is well known for supplying the Heli-Cal beam style shaft coupling, but it is not widely known that the same product can be utilised as a machined spring Combining the flexure concept with any form of end attachment has always been one of our greatest advantages

Abssac has recently successfully completed a wrap spring application combining a lever arm, bearing mount with a retaining ring groove and positional mechanical stops.

The application called for incrementally rotating a six-position carousel using a pneumatic cylinder.

The wrap spring is supported on a bearing, which is mounted on one end of the spring and is held in place by a retaining ring.

A lever arm extends from the spring, which attaches to a pneumatic cylinder.

A notch in the wrap spring encompasses a stop pin, which limits rotational travel to the required sixty degrees.

The carousel support shaft is concentric within the wrap spring and is gripped by it.

As the pneumatic cylinder is extended, it rotates the wrap spring in the ball bearing and the carousel rotates with it to the next position.

When the pneumatic cylinder retracts, the wrap spring releases its grip and rotates without the carousel to the original position.

The clutching action of the wrap spring provides incremental unidirectional rotational motion and it's all achievable from one piece of material.

Machined springs provide an excellent foundation for integrating several useful features and functions into a single spring part.

Applications range from deep space instrumentation to medical apparatus on earth. Request a free brochure from Abssac ...
