Abstract
The invention relates to a manipulator transmission device. The manipulator transmission device comprises a ball screw and a guide rail which are arranged in parallel. A screw nut is sleeved on the screw, the ball screw is connected with a driving motor, and the ball screw and the guide rail are arranged on a support in parallel. The manipulator transmission device is characterized in that a support plate connecting seat is sleeved on the guide rail which is slidingly connected with the guide rail, and the screw nut is connected with the support plate connecting seat through a nut connecting seat in a floating mode. Even when the ball screw or the guide rail is deformed during application, the manipulator transmission device can also achieve adjustment of transmission errors, structurally reduce the assembly precision requirements of the ball screw and the guide rail and meanwhile reduce the noise.
