Abstract

The invention discloses an assembly technology of a precise cycloidal speed reducer. The assembly technology of the precise cycloidal speed reducer mainly comprises the following steps of A detecting and grouping key parts, B installing a crankshaft into a coordinate hole of a cycloidal gear, C installing an output disk supporting shaft into an output disk, D assembling an inner gear, E placing the cycloidal gear and a crankshaft assembly into the inner gear, F installing a pin gear, G installing an input end disk, H adjusting the axial clearance of tapered roller bearings of the crankshaft and I installing a planet wheel and a center shaft. According to the assembly technology of the precise cycloidal speed reducer, the key parts are assembled in a grouped manner, the assembly difficulty is lowered, and the tolerance fit precision is improved; shrink fitting is applied to the pin gear, so that the problem that interference is prone to happen in the installation process of the pin gear is solved, the assembly technology is reasonably optimized, and the assembly quality of the whole machine is improved.

Description

technical field

[0001] The invention belongs to the field of mechanical assembly and relates to an assembly process of a precision circular reducer. Background technique

[0002] As a precision transmission mechanism with few teeth differences, the precision circular reducer is composed of the first-stage spur gear reduction part and the second-stage circular gear reduction part. The specific structure mainly includes a sun gear, a planetary wheel, a crankshaft, a circular gear driven by the crankshaft, an internal gear with an arc containing groove, and a supporting mechanism. Among them, the circular gear is mainly formed by rolling the circle based on the motion on the circle, similar to the cycloid gear. The reducer has outstanding characteristics such as compact structure, large transmission ratio, high transmission precision, and strong bearing capacity. It can be widely used in industrial robot joint drive systems, aerospace, CNC machine tools, national defense weapo...
