() I (1) (2) (3) (4) (5) (6) II Abstract This design is the design of the lower limb rehabilitation robot device mixed rigid flexible. Here mainly include: Design of ball screw drive system, the graduation design on the design of the basic skills training, enhancing the analysis and to solve engineering problems, and create a certain condition for general mechanical design. The structure is mainly produced by the motor power through the coupling will need to transfer the power to the screw rod, the screw rod drives the screw rod nut, thereby driving the movement, improve labor productivity and automation level of production. But also show its superiority, there are broad prospects for the development. The research of this thesis: (1) the rigid flexible hybrid lower limbs rehabilitative robot device structure design. (2) analysis of lower limbs rehabilitation robot device performance mixed rigid flexible. (3) the choice of motor. (4) transmission system, execution unit and frame design of rigid flexible hybrid lower limbs rehabilitative robot. (5) the design of components for the design calculation and check. (6) to draw the assembly drawing and parts assembly diagram and parts diagram design. Key words: rigid flexible hybrid lower limbs rehabilitative robot device, coupling, ball screw III IV 1 1 1.1 1 1
