Abstract

A reduction gear with a multistage speed reducing function comprises a spindle, planet wheels, crankshafts, a shell and cycloidal-pin wheels. The shell is of a hollow barrel-shaped structure, and thespindle is coaxially arranged in the geometric center of the shell. The two crankshafts are parallel to the spindle, and are arranged on a circle with the spindle as the center at an equal radian. Theplanet wheels are fixedly arranged at the lower ends of the crankshafts, and a gear is fixedly arranged at the lower end of the spindle. The gear is engaged with the two planet wheels. The spindle issleeved with the two cycloidal-pin wheels, holes are formed in the positions, on the crankshafts, of the cycloidal-pin wheels, and the crankshafts penetrate through the holes. Outer ring ball bearings are arranged on openings in the two ends of the shell correspondingly, the outer rings of the outer ring ball bearings are fixedly connected with the inner side walls of the ends of the shell, and end covers are fixedly arranged on the inner rings of the two outer ring ball bearings. According to the reduction gear, output force is evenly distributed, the structure is simpler and more efficient,and the assembling process is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of speed reducers, in particular to a multi-stage speed reducer. Background technique [0002] Existing RV reducers are mainly used in industrial robots, machine tools, medical testing equipment, satellite receiving systems and other fields. However, the existing RV reducer is easily affected by excessive impact load, and the bearing life is short. In addition, it is heavy and has a large external dimension. At the same time, the structure of the reducer is complex, disassembly and assembly are time-consuming and labor-intensive, and maintenance or inspection is inconvenient. Contents of the invention [0003] The object of the present invention is to provide a multi-stage speed reducer to solve the above problems. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A multi-stage deceleration reducer, including a main shaft, a planetary wheel, a ...
