planetary reduction mechanism

Abstract

The invention provides a planetary reduction mechanism which comprises a planetary reduction gearbox, a fixed connection cover and a belt wheel of a hollow structure. An output shaft of the planetary reduction gearbox stretches out of the first end of a shell of the planetary reduction gearbox. An input shaft of the planetary reduction gearbox stretches out of the second end of the shell and is provided with a locking hole. A fastening screw is arranged in the position of the input shaft in a penetrating mode. The hollow structure penetrates through the belt wheel, and a containing cavity with a reverse inlet and a forward opening is formed. The second end of the shell penetrates into the containing cavity from the reverse inlet, and the input shaft is exposed out of the forward opening. The belt wheel is further provided with an exposure operating opening which communicates with the containing cavity and is used for allowing the fastening screw to be exposed. The fixed connection cover comprises a column part and a cover part fixedly connected with the column part. The column part penetrates through the forward opening and is inserted into the locking hole. The cover part is overlapped with the belt wheel and fixed to the belt wheel. An operator makes the operating opening be exposed and screws the fastening screw so as to selectively lock the column part or release the column part, so that the thickness is smaller, the stability is better, and the precision is higher.

Description

technical field [0001] The invention relates to a manipulator, in particular to a planetary reduction mechanism for the manipulator. Background technique [0002] With the continuous development of the economy and the continuous progress of science and technology, it provides a strong economic and technical support for the development of the enterprise, and promotes the enterprise to move towards the direction of intelligence and high integration, and the manipulator is the intelligent machine developed by the enterprise. One of the products. [0003] Among them, in order to reduce the burden on the operator, or replace the operator to perform dangerous operations, the application of the manipulator is inseparable. The manipulator is used to replace the operation of the operator, thereby achieving the purpose of improving efficiency or protecting the operator. Therefore, the manipulator is widely used in automatic production, and effectively solves the problem of increasing...

Problems solved by technology

Since the swing arm is fixedly connected to the output shaft of the planetary gearbox, the input shaft of the planetary gearbox passes through the flange seat on the shell of the planetary gearbox, and the driven pulley in the pulley transmission is assembled on the input shaft, so that The flange seat is between the driven pulley and the housing, so the space occupied by the driven pulley and the planetary gearbox is increased along the axial direction of the input shaft, resulting in a bulky defect; correspondingly, the planetary The overall weight of the gearbox, thus affecting the smoothness and precision of the movement
