Abstract

The invention discloses a variable stiffness coupling and a variable stiffness driving mechanism, and relates to the field of robot compliance control. Invented to simplify the structure of VSA and increase the adjustable range of transmission stiffness. A variable stiffness coupling and a variable stiffness drive mechanism provided by the present invention include a first half coupling and a second half coupling, and the first half coupling and the second half coupling pass through The elastic reed transmits torque and is supported by an elastic support body. One end of the elastic reed is fixedly connected to the first half-coupling, and the other end is slidably connected to the second half-coupling. The first half-coupling can The elastic reed is driven to slide axially relative to the second coupling half. The invention can be used in joint design of service robots.

Description

technical field [0001] The invention relates to the field of robot compliance control, in particular to a variable stiffness coupling and a variable stiffness drive mechanism. Background technique [0002] Variable Stiffness Actuator (VSA: Variable Stiffness Actuator) is an important subject of robot compliance control at present. It is mainly used in the joint design of service machines and the drive and perception of human-machine safety interaction electromechanical equipment. In recent years, the European Union, the United States, and Japan are actively developing various VSAs. [0003] The variable stiffness drives that have been implemented so far mainly include the following types: [0004] 1. An antagonistic VSA that adjusts the tension of two nonlinear springs through a pair of motors; [0005] 2. The VSA realized by compressing the nonlinear spring through the cam mechanism to change the rigidity of the drive connection; [0006] 3. Adjust the tension of the bel...
