Problems solved by technology

[0003] When the prime mover cannot rotate in both forward and reverse directions, such as an internal combustion engine, but the working parts need to rotate forward and reverse, the planetary reduction mechanism without the function of forward and reverse two-way rotation cannot be applied to this working condition
[0004] If a planetary mechanism is used to achieve gear shifting, and the multi-gear gear shifting of the mechanism is realized through gear shifting, when the technical indicators are the same, the parallel shaft mechanism and the planetary mechanism have the same volume when the transmission power is small, and when the transmission power is the same, the volume is large , compared with the planetary transmission, the variable speed range of the variable motor is much smaller

Abstract

The invention provides a coaxial line planetary transmission gear ring output multi-gear speed change mechanism. The gearshift mechanism can adopt a planetary mechanism to realize gearshift in one direction, that is the gearshift mechanism is only provided with a forward gear, in addition, the gearshift mechanism can realize gearshift in two directions as needed, that is the gearshift mechanism is provided with both a forward gear and a reverse gear; the coaxial line planetary transmission gear ring output multi-gear speed change mechanism is provided with an input end and an output end; an input shaft inputs power; the final gear can be gear ring output and planet carrier output, and other gears are gear ring output; the rotating speed of the output end is low, so that compared with an input end gearshift mechanism, the output end gearshift mechanism is easier and more reliable in gearshift and higher in efficiency; and compared with a parallel-axis gearshift mechanism, the gearshift mechanism has the advantages of being small in occupied area, large in transmission ratio range, high in bearing capacity and capable of realizing speed change with a high speed ratio.

Description

technical field [0001] The invention relates to the field of speed reducers, in particular to a low-speed gearshift, that is, a planetary transmission forward and reverse bidirectional multi-speed gearshift mechanism for shifting gears at the output end of the gearshift mechanism. Background technique [0002] Planetary transmission is widely used in the slewing mechanism of construction machinery, traveling mechanism and power head of piling machinery, etc. The speed of these mechanisms is changed by shifting gears with the help of parallel shaft mechanisms, and some use variable motors to achieve speed change. [0003] When the prime mover cannot rotate in both forward and reverse directions, such as an internal combustion engine, but the working parts need to rotate forward and reverse, the planetary reduction mechanism without the function of forward and reverse two-way rotation cannot be applied to this kind of working condition. [0004] If a planetary mechanism is use...
