Abstract
The invention discloses a modular differential compliant displacement reducer with output in same direction or reverse direction of input. The modular differential compliant displacement reducer includes a forward motion module, a reverse motion module and an actuator, and two ends of the forward motion module are respectively connected to one end of the reverse motion module. Differential superposition of displacement is achieved through combination of the forward motion module and the reverse motion module, a large displacement reduction ratio can be obtained, and therefore the resolution ratio and precision of motion are greatly improved. The reducer can be matched with a macro-motion platform, and large-range and ultrahigh-precision motion positioning is achieved.
