Embodiment Construction

[0039] The invention includes upper and lower boxes, internal gears, planetary frames, planetary gears, sun gears, upper and lower support plates, support shafts, sliding bearings, dust covers, nuts, steel balls, bearing collars, upper and lower boxes Body cover, bolt, input shaft, positioning sleeve, rolling bearing, sleeve, output shaft, bevel gear, key, positioning circlip.

[0040] The upper and lower boxes are cylindrical. After the upper and lower boxes are sealed and fixed by screws, there is a cylindrical cavity inside. The upper surface of the upper box and the lower box along the longitudinal centerline of the upper and lower boxes There are cylindrical bosses and conical bosses on the bottom surface respectively. There is a blind hole in the cylindrical boss. The bottom of the blind hole has a circular hole communicating with the cylindrical cavity in the upper box. The end surface of the cylindrical boss There is a dust-proof cover on the top, and there is a round ...

Abstract

A planet gear speed reducer comprises upper and lower boxes, an inner gear, a planet support, a planet gear, a sun wheel, upper and lower support plates, a sliding bearing, a steel ball, an input axle, an output axle, a rolling bearing, a muffle, upper and lower box end covers. The invention has strong carrier and overload abilities with compact structure and reduced noise.

Description

technical field [0001] The invention relates to a planetary gear transmission reducer, in particular to a planetary gear transmission reducer with a large transmission ratio in space, which is widely used in metallurgy, mining, chemical industry, engineering machinery and other mechanical equipment, and is especially suitable for joint drive of manipulators of industrial robots. Background technique [0002] Commonly used reducers mainly include ordinary cylindrical gear reducers, worm gear reducers and planetary gear reducers. However, in the face of increasingly diverse transmission forms and power requirements, it can no longer meet the needs of production, and the exposed problems are becoming more and more obvious. Ordinary cylindrical gear reducer, although the structure is relatively simple, but the coincidence degree is not high, often need to use gear displacement modification to meet the transmission requirements, for large transmission ratio ordinary cylindrical g...
