Parallel planetary reducer of novel structure

Abstract

The invention relates to a parallel planetary reducer of a novel structure. The parallel planetary reducer is characterized in that a series connection structure of a multi-stage planetary system of a traditional planetary reducer is changed into a parallel connection structure of the multi-stage planetary system, and the parallel planetary reducer comprises multiple stages of sun gears, multiple stages of planetary gears, multiple stages of planetary carriers, multiple stages of inner and outer gears and a gear ring. Each group of the sun gear, the planetary gear, the planetary carrier and the inner and outer gear form one stage of planetary gear train. Each inner and outer gear can be used as the output of the previous stage of planetary gear train and can also be used as the input of the next stage of planetary gear train, by the aid of the structure, the multiple stages of planetary gear trains are connected in parallel through the inner and outer gears, and the output of the reducer is achieved through the novel structure and the planetary transmission principle. According to the parallel planetary reducer, the axial size of the planetary reducer is shortened structurally, the application range of the planetary reducer is expanded, a theoretical foundation is laid for structural innovation of the planetary reducer of the novel structure, and more choices are provided for model selection of the reducer of a main machine in engineering machinery.

Description

technical field [0001] The invention relates to a planetary reducer in the mechanical field, in particular to a parallel planetary reducer with a new structure. Background technique [0002] The planetary reducer has the function of reducing the speed and increasing the output torque. It is widely used in various fields such as construction machinery, ship heavy industry, aerospace, and precision machine tools. Planetary reducers are needed. With the emphasis on the machinery manufacturing industry in the future, the demand for planetary reducers by major enterprises is constantly expanding, and the requirements for the structure and performance of reducers are also getting higher and higher. [0003] At present, most researchers are mostly based on the transmission principle of the existing planetary reducer, from improving the performance index, improving the material, sealing, lubrication and other aspects of each component, so as to improve its actual service life or mak...

Problems solved by technology

In some special working conditions, the radial size of the output end is very large, sometimes even tens of meters. If a planetary reducer with a series structure is used, more than a dozen or even dozens of reducers are required to be evenly distributed at the output end to achieve output. demanding, costly and bulky
