Sd Oscillator

Camfield Engineers offers the SD Oscillator, developed to provide smooth, positive, cam controlled rotary-linear combined motions to an external output shaft. A compact housing encloses the internal parts and provides (6) different mounting surfaces to suit a wide variety of installations. The modified construction avoids the necessity of providing openings in the mounting base plate for clearance purposes. Three types are available: Type A – oscillating-linear output movement wherein the output shaft reverses its rotation after each complete linear stroke; Type B – intermittent-linear output permitting rotary indexing after each complete linear cycle, both types allow input shaft rotation in either direction with the corresponding output rotation; and Type C – rotation only-no linear movement. Operation: rotation of the input drive shaft (cw or ccw) causes a track cam and lever to produce linear movement of the output shaft. Positive angular positioning is obtained by the engagement of a pair of needle type cam rollers with a hardened and ground guide key(s). A suitable fitting rib cam follower keeps rotational backlash to the minimum necessary for high speed operation and exact angular stopping. Specials: since the rotational motion is a direct function of the cam stroke, any angular movement less than 180 degrees is obtainable with the addition of a special cam and positional locking rollers. Non standard linear strokes and shaft extensions are also available. Additional features: The oscillators may be mounted in any position with (6) different mounting surfaces provided. Optional mount bases are available, the output shafts are unhardened to permit customer drilling or reaming operations, an optional tubular linear output shaft is available to provide pneumatic, vacuum or electrical accessibility to output tooling.
