Abstract
Displacement reduction mechanisms using leverages consisting of elastic leaf springs are widely used due to capability of linear motion. One application of the reduction mechanism is to provide a precise motion as a standard of a displacement of nanometers. However, large reduction rate exceed 1/1000 has not been yet achieved because the fulcrum of the leverage cannot endure a large stress of leverage in the mechanisms. Therefore, a displacement reduction mechanism over 1/1000 reduction rate is newly proposed here where twisting hinges using elastic leaf springs are applied as leverage fulcrums. The twisting hinge can provide an accurate twisting motion without a leverage fulcrum deformation. This paper describes the performance of the displacement reduction system.
