Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in fig. 1:
the planet wheel 3 is arranged on the pin shaft 2 inside the planet carrier 1 through two planet wheel bearings 5, a space ring 4 sleeved on the pin shaft 2 is arranged between the two planet wheel bearings 5, namely, the two planet wheel bearings 5 are separated by the space ring 4.
The space ring 4 is provided with a plurality of radial through holes which are uniformly distributed in a circle and are used as a space ring oil path 40.
The pin shaft 2 is provided with an axial blind hole 21, the axial blind hole 21 is a frustum-shaped opening 211, namely a V-shaped opening, on the end surface of the pin shaft 2, the pin shaft 2 is provided with a circle of radial through holes 22 which are uniformly distributed circumferentially, each radial through hole 22 is communicated with a spacer ring oil way 40, each radial through hole 22 is communicated with the spacer ring oil way 40 and the axial blind hole 21, and the axial blind hole 21 and the radial through holes 22 form a pin shaft oil way 20.
An oil stirring hole 10 is formed in the end face of the planet carrier 1, and the oil stirring hole 10 is communicated with an axial blind hole 21 of the pin shaft 2.
