Abstract

The invention discloses a 90-degree reversing transmission structure. The 90-degree reversing transmission structure comprises a mounting bracket, a synchronous belt assembly, a driving mechanism, an output shaft and an idle wheel assembly, wherein the idle wheel assembly comprises a shaft piece and an idle wheel; the shaft piece is connected with the mounting bracket; the idle wheel is rotatably arranged on the periphery of the shaft piece in a sleeving manner; the synchronous belt assembly comprises a synchronous belt, a driving belt wheel fixed with a driving shaft of the driving mechanism and a driven belt wheel fixedly connected with the output shaft; a rotating shaft of the driving belt wheel is perpendicular to a rotating shaft of the driven belt wheel; one end of the synchronous belt is wound on the periphery of the driving belt wheel, the other end of the synchronous belt is wound on the periphery of the driven belt wheel, and the middle part of the synchronous belt is wound on the periphery of the idle wheel; and the synchronous belt is supported by the idle wheel to change the direction and is finally distributed in an L shape. According to the 90-degree reversing transmission structure provided by the invention, a bevel gear transmission structure in the prior art is changed into a synchronous belt transmission structure, so that 90-degree transmission of power is realized.

Description

technical field [0001] The present application relates to the technical field of power transmission equipment, and more specifically, relates to a 90° reversing transmission structure. Background technique [0002] There are many elbow joints and wrist joint transmission structures of industrial robots, which often require a 90-degree angle between the power input and output to achieve 90-degree power transmission. At present, the commonly used transmission structure is the matching structure of spur gears and bevel gears. However, for certain requirements (such as space requirements), it is difficult to use the traditional transmission structure to meet the requirements. Installation, installation of bevel gears, and adjustment of bearing clearance are difficult. The machining accuracy of gears and bevel gears is high, the cost is high, and problems such as abnormal noise are prone to occur. [0003] Therefore, how to provide a solution to the above technical problems is a...
