Optimize your automation budget with our professional Intermittent Rotary Drive Based On Cylinder drawing. In many assembly and packaging applications, a full servo-driven rotary table is an over-engineered and costly solution. This technical CAD resource provides a robust mechanical alternative: a conversion mechanism that transforms the linear stroke of a standard pneumatic or hydraulic cylinder into controlled, incremental rotary steps. By downloading this file, you gain access to a proven “ratchet and pawl” or “index pin” architecture that provides reliable 90-degree, 180-degree, or custom-angle indexing with high holding torque.

The engineering focus of this design is the conversion linkage and the unidirectional clutch mechanism. The drawing includes detailed schematics for the rack-and-pinion or bell-crank assembly that drives the rotary hub, along with the essential secondary locking pin that ensures the table remains rigid during the “dwell” phase. By utilizing this blueprint from MechStream, you can build a rotary station that is powered by simple factory air, making it ideal for explosion-proof environments or low-cost automation cells where electrical complexity needs to be minimized.

Our technical documentation prioritizes timing and shock absorption. The assembly features integrated hydraulic cushions or pneumatic snubbers at the end of the cylinder stroke to prevent “bounce” and ensure a soft landing at each index point. Whether you are designing a rotary assembly carousel or a parts-feeding dial, this drawing provides the exact geometric relationships, bearing tolerances, and material specifications required to ensure a smooth, repeatable, and long-lasting indexing solution.

Caractéristiques principales :

  • Linear-to-Rotary Conversion: Efficiently transforms standard cylinder strokes into precise angular increments.
  • Positive Mechanical Locking: Includes a secondary shot-pin or wedge design to guarantee zero-drift during machining or assembly operations.
  • High Torque Output: Leverages the high force of fluid power to rotate heavy loads that would stall comparable electric motors.
  • Adjustable Indexing Angles: The design allows for modifications to the stroke length or gear ratio to achieve different rotational steps.
  • Shock-Dampened End Stops: Features integrated damping zones to reduce mechanical stress and noise during high-speed indexing.
