A bearing module that supports adjacent ends of coaxial shafts, includes an outer ring having first and second axially adjacent raceways and first and second flanges located at the respective ends. A first group of rolling elements rolls on the first raceway, and a second group of rolling elements rolls on the second raceway. A first cage retains the first group of rolling elements circumferentially spaced apart from one another, and a second cage retains the second group of rolling elements. An axial bearing is retained axially between the first and second groups of rolling elements, and has axial bearing rolling elements that are configured for rolling contact with (a) facing axial side raceways on first and second inner rings supported respectively on the first and second groups of rolling elements, (b) the adjacent ends of the two coaxial shafts, or (c) integral washers of the axial bearing.

Bearing module for coaxial shaft ends

A planetary transmission assembly including a composite planetary staking pin is disclosed. The composite planetary staking pin fixes a planetary gear to a planetary carrier, and the planetary gear is supported on the composite planetary staking pin by rolling elements. The composite planetary staking pin includes an inner pin body having axial ends with circular grooves. The composite planetary staking pin is fixed to the planetary carrier via staking of the axial ends of the inner pin body. An outer sleeve of the composite planetary staking pin is fixed to the inner pin body. The outer sleeve defines a circumferentially extending helical channel that provides a lubricant flow path between an inlet defined by the planetary carrier and an outlet to the rolling elements.

Composite planetary staking pin with lubrication feed feature

A planetary pin used for staking in a planetary gear system is provided. The planetary pin comprises a cylindrical body, a first end having a first end surface, a second end having a second end surface, and a circular groove formed in at least one of the end surfaces concentric with the cylindrical body.

Staked planet pin

A planet pin for use in a planetary gear system and a gear system including a planet pin are disclosed. The inventive planet pin provides a plurality of radial passages in fluid communication with an axial passage which can advantageously eliminate, or substantially reduce, the need to orient a planet pin in a planetary gear system.

Orientation-free planetary pin for lubrication of planetary bearings

A machine element that has at least one rotationally symmetrical section which is configured like a hollow body. In the machine element at least the rotationally symmetrical section is formed from two elements of bowl-shaped design which close the machine element on the end side and in the process enclose at least one cavity.
