Worm-type gear is low-cost alternative to conventional designs

Paul Boughton
Dynamic Automation has developed an innovative precision gearing that works with standard machine screws or threaded studding and adapts to rotary or linear motion applications. According to design engineers at the McClellan Air Force Base, this gear solved one of their toughest mechanical engineering problems when space was restricted. This gear has been used to drive a sample carrier 100 inches deep under the water with very slow speed at 10 inches per minute. Without the screw-driven worm gear, the task would have been dangerous because of the high-radiation environment.
This precision gear is now available in a variety of standard sizes or can be made to order for custom needs. It is capable of fine adjustment and positive positioning, and at a cost considerably less than special-order mating worms.
