The invention belongs to the technical field of
mechanical transmission, and particularly relates to a split
planet carrier
assembly facilitating positioning of a
planet wheel shaft. The
assembly comprises a main
planet carrier, an auxiliary planet carrier, a planet wheel, the planet wheel shaft, a needle bearing, a bearing spacer ring, an anti-wear pad and positioning steel balls. In order to ensure that an oil passage hole on the planet wheel shaft is aligned with an oil passage hole on the auxiliary planet carrier so that lubricating
oil can smoothly enter an inner hole of the planet wheelshaft and provide
lubrication for the needle bearing of the planet wheel, it must be ensured that the planet wheel shaft does not rotate circumferentially or move axially in the working process. According to the split planet carrier
assembly facilitating positioning of the planet wheel shaft, the
steel ball positioning type is adopted, the steel balls are arranged in the planet wheel shaft and themain planet carrier, and are matched with a cylindrical groove on the planet wheel shaft and a semi-cylindrical groove on the main planet carrier respectively, so that the planet wheel shaft can be positioned, the structure is simple and compact, the assembly and the repeated disassembly are easy, and the
steel ball positioning type has higher reliability compared with the
modes of fixing screw positioning, end face mortise
punching and the like.
