Roller Pinion Gear Steps Up Rotopod Robot Motion

From Nexen Group, Inc.

Mikrolar's engineers found a way to achieve faster, quieter and more precise operation of the ring gear system. They found Nexen's Roller Pinion Gear (RPG), which replaces the traditional tooth spur gear design with a roller system that functions more smoothly. Instead of creating a slapping motion as gear and pinion teeth interleave, the roller gear system moves in a tangent path and rolls down the tooth face.

Linear Slides and Linear Stages
Linear slides are simple linear motion devices composed of a stationary base and a moving carriage. Linear stages are slides with a drive mechanism that provide controlled, precise positioning along a linear axis.
Rack and Pinion Drives
Rack and pinion drives use a rotational motor to affect linear motion via a rack and pinion combination. They are used frequently in long-travel applications, such as machine tool table positioning, that require high stiffness and accuracy.
