Planet row and assembly process thereof

Abstract

The invention relates to a planet row which comprises a sun wheel, a planet wheel and a planet frame, wherein the sun wheel is arranged in the cavity of the planet frame; the planet wheel is supported on the planet frame; a first thrust bearing is arranged between one end face of the sun wheel and the planet frame; a second thrust bearing is arranged on the other end face of the sun wheel; the excircle radius of the first thrust bearing and the second thrust bearing are more than the minimum distance from a tooth crest of the planet wheel to the central line of the planet frame; the thrust bearing is contacted with the surface of the planet wheel; therefore, the planet row can bear higher axial load; a screw passes through the planet frame, is inserted into the other end of a radial through hole and then is sealed; alignment communication of oil ways and the radial through hole is ensured; the planet row is more convenient to install and detach; a gear is arranged at one end of the planet frame; the gear can transmit power to a differential mechanism; the structure is compact; an axial space is saved; the gear and a terminal pad are in welded connection; the planet row is convenient to process; a planet axle is tightly pressed and fixed on the planet frame through the terminal pad; and the planet row is more convenient to install.

Description

technical field [0001] The invention relates to a power transmission device for a transmission, in particular to a planetary row and its assembly process, and belongs to the field of mechanical technology. Background technique [0002] The planetary transmission is mainly used to transmit power and is an important part of the planetary transmission, and its structure is relatively complicated. Due to the complex structure of the planetary row, the assembly sequence of each part is particularly important. A reasonable and effective assembly process can improve production efficiency, reduce costs, and provide a reliable guarantee for product quality. [0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art. Generally, thrust bearings are not provided at both ends of the traditional planetary row sun gear, and such a planetary row cannot bear axial loads; In many cases, the planetary row is r...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a planetary row and its assembly process in view of the above deficiencies, which overcomes the defects in the prior art that the planetary row cannot bear a large axial load, is not easy to disassemble and takes up a large space. After the planetary row and assembly process described above, the planetary row has a strong ability to withstand axial loads, is easy to disassemble, and saves axial space
