Linear Motion Mechanisms for Fine Position Adjustment of Heavy Weight Platforms

Abstract

This paper describes the design, development and experimentation of the linear motion mechanisms for very fine position adjustment of heavy weight platforms. It is proposed the concept that includes the precise electric motor/actuator, the ball-screw motion transducer and the no-backlash motion reducer based on compliant/elastic mechanism. The design, experimental equipment and results from measurements are presented. Such configuration enables to use available ball-screw mechanisms and to reduce the cost of the whole positioning system.
