Title:
VARIABLE-IMPEDANCE SHAFT COUPLING
Document Type and Number:
Japanese Patent JP2015096734
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a shaft coupling that makes a spring constant and an attenuation coefficient variable.SOLUTION: Relative rotational displacement between input and output axes is separated from axial rotation by using a mechanism for compensating for the rotational displacement. The relative rotational displacement is converted to linear displacement by a rack-and-pinion mechanism. Sliding resistance is exerted by a spring-damper system. Thus, mechanical impedance is adjusted. When an existing variable spring constant spring or a variable attenuation coefficient damper is utilized, a variable impedance mechanism is obtained without component replacement.
