Power Transmission, Actuators & Mechanics
Power transmission systems can be built around one or multiple, synchronized actuators that turn input energy into output movement. Mechanical actuators convert the rotary motion of a control handle or knob into linear motion through attached gears or other configurations. Ball screw or lead screw actuators produce motion by rotating a nut and moving a shaft linearly, wheel and axle actuators rotate a wheel in order to move a cable, rack, chain, or belt. Other types include pull-oriented actuators like hoists or chain drives and push-only ones like cam actuators that rotate a wheel-like cam to deliver thrust at a shaft’s base.
Within mechanical power transmission systems, torque is additionally transformed through belts that reduce slippage, shafts and the couplings that join them, and related moving components, from chains to sprockets to gears. Drive components include clutches, brakes, gears, and variable speed motors, gearboxes or speed reducers.
Also included in this product category are positioning stages and slides that are used in motion control systems to hold down a work piece or position it for some operation.
Finally, industrial robots are included as they are automatically controlled, multipurpose manipulators programmable in three or more axes that perform a variety of tasks in automation systems.
