IMC Servo-Mechanical Drives combine the flexibility of a servomotor with the accuracy and reliability of a camdriven index drive. They can are ideal for dial, conveyor, or linkage applications. The drives are offered in several configurations
The Flex-i-Dex drive is a dedicated Servo-Mechanical package complete with servomotor and amplifier ideal for light duty applications or short, fast movements.
Constant Lead cam drives are standard RDM or Heavy Duty E-Series drives with constant lead (constant ratio) cams. Supplied with or without a reducer and servomotor package, they offer a large mounting surface, bearing support and thru-hole. Supply your own servo package or use ours.
The Servo-Mechanical Drive is a zero-backlash, high-efficiency, long-life, low-maintenance precision rotary actuator. The actuator consists of an IMC indexer with a constant ratio cam and a servomotor. A secondary reducer may be added for applications requiring a very slow movement, extra mechanical advantage or motor inertia matching. The Servo-Mechanical Drive features:
Large Output Flange and Bearing with metric or imperial tapped holes for fastening the load.
Large Center Hole for a stationary center post or to run air, hydraulic or electric lines.
Output shaft with precision cam followers meshes with a hardened and ground cam. The cam is made with a fixed ratio from 2:1 to 24:1. Low ratios are recommended for large angular movements while high ratios are used for small, fast movements.
Zero Backlash is produced by preloading the cam followers against the cam surface.
High Efficiency due to cam followers rolling (not sliding) on the cam while submerged in oil.
