General

J Trans-part Series Introduction:

The Stelron TRANS-PART has been developed to provide smooth, positive, cam controlled Linear-Rotary motions to an external output shaft. A compact housing encloses the internal parts and provides for mounting on any five different surfaces to suit a wide variety of installations. Four different standard output motion types are available.


Size & Range

The J Series TRANS-PART is offered in six standard sizes with output shaft diameters ranging from ½” up to 3″, and linear strokes up to 10″  maximum. Most size units are available in a wide variety of standard output rotation periods. Each model size includes four basic types of standard motions. Non standard output rotations and linear strokes can be designed as special.

Capacity:

The engineering and example guide section (ref. pages 24 & 25) contains the necessary information to determine the proper size and cam requirements for most applications. Speeds, strokes and cam timing can have a marked effect on both the dynamic loads generated and the capacity of the TRANS-PART. Stelron engineers are experts in the field of cam design and will provide assistance in determining the best motion for your application.

Accuracy & Repeatability:

The accuracy and repeatability are variable depending upon the size of the TRANS-PART selected, see table on (page 3 of the catalog).

Construction:

The cast aluminum housing design provides for a rigid enclosure. The Stelron TRANS-PART utilizes large diameter cams for low wear and maximum motion flexibility. Cams are hardened and ground. A cam follower attached to the rack carriage block directly engages the rotate cam. The “Y” linear axis operates through a lift lever and flange mechanism. The output shaft is supported by high quality linear guide bearings. Stelron TRANS-PART features all rolling contact throughout the mechanism and incorporates the latest advances in linear and rotary bearing design.
