Problems solved by technology

Although the cantilevered pin shaft can compensate the assembly error when the sun gear and the planetary gear are meshed, this compensation will cause the actual deformation of the pin shaft to be uneven, resulting in uneven load distribution on the sun gear and planetary gear, thereby increasing Eliminates the risk of cantilever pin breakage

Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing.

[0018] figure 1 A carrier mechanism 50 for a planetary gear train according to the invention is shown. The bearing mechanism 50 includes a first bearing member 5 and a second bearing member 4 connected to the first bearing member 5 in a spaced manner and capable of elastic deformation. The second carrier 4 should be made of a rigid metal material, preferably a high-strength metal material, so that it has better rigidity and better elastic deformation ability. In order to facilitate the assembly of the sun gear 1 , a circular hole 15 larger than the outer circumference of the sun gear 1 may be provided at the center of the second carrier 4 .

[0019] According to the invention, the intermeshing sun gear 1 and planet gears 2 of the planetary gear train are mounted between a first carrier 5 and a second carrier 4 . The planetary gear 2 is connected between the first carrier...

Abstract

The invention discloses a bearing mechanism for a planetary gear train. The bearing mechanism comprises first bearing pieces arranged on the two sides of a sun gear and a planetary gear of the planetary gear train respectively and engaged with one another and second bearing pieces connected with the first bearing pieces and capable of being elastically deformed. According to the bearing mechanism for the planetary gear train, the assembly error caused when the sun gear and the planetary gear are engaged can be effectively compensated to balance the loads of the sun gear and the planetary gear and ensure that the planetary gear is safe to use.

Description

technical field [0001] The invention relates to a planetary gear train, in particular to a bearing mechanism for bearing the planetary gear train. Background technique [0002] As we all know, in a planetary gear train, the planetary gears are usually mounted and fixed by pin shafts. In the actual operation process, the sun gear and planetary gear usually need to compensate the assembly error at the meshing point through the deformation of the pin shaft. In order to enhance the compensation capability of the pin shaft, the pin shaft is designed as a cantilever pin shaft, that is, one end of the pin shaft is fixed and the other end is freely suspended. Although the cantilevered pin shaft can compensate the assembly error when the sun gear and the planetary gear are meshed, this compensation will cause the actual deformation of the pin shaft to be uneven, resulting in uneven load distribution on the sun gear and planetary gear, thereby increasing The risk of cantilever pin f...
