Abstract
A planetary gear system with a planetary carrier and a plurality of planetary gearwheels which are mounted on the planetary carrier by way of planetary gear bolts and planetary bearings. Each planetary gear bolt has at least one bore for supplying the planetary bearings with lubricating oil. The at least one bore is associated with an oil-catching element of a component fixed onto the planetary carrier, and the component is designed, in addition, to be a pulse generator for a rotational speed sensor. The pulse generator has a plurality of raised areas which are arranged around the circumference of the component and which extend in the axial direction.

A planetary gear system with a planetary carrier and a plurality of planetary gearwheels, which are mounted on the planetary carrier by way of planetary gear bolts and planetary bearings,
- each of the planetary gear bolts having at least one bore for a supply of lubricating oil to the planetary bearings,
- the at least one bore being associated with an oil-catching element of a component fixed on the planetary carrier,
- the component, in addition, being designed as a pulse generator for a rotational speed sensor,
- the pulse generator comprising a plurality of raised areas which are arranged around a circumference of the component and which extend in an axial direction,
- the raised areas, extending in the axial direction, are of a roof-shaped form and are arranged, in each case, obliquely or parallel relative to roof surfaces in a radial plane, and
- the raised areas, extending in the axial direction, form first openings, which are open inward in a radial direction.
A component for a planetary gear system with at least one planetary carrier and a plurality of planetary gearwheels, the component comprising:
- an oil-catching element,
- a pulse generator for a rotational speed sensor,
- the pulse generator being in a form of a plurality of roof-shaped raised areas arranged around a circumference of the component for the planetary gear system,
- the raised areas extend in an axial direction, and
- the raised areas, extending in the axial direction and constituting the pulse generator, form the oil-catching element.
A component for a planetary gear system with at least one planetary carrier and a plurality of planetary gearwheels, the component comprising:
- an oil-catching element,
- a pulse generator for a rotational speed sensor,
- the pulse generator being in a form of a plurality of roof-shaped raised areas arranged around a circumference of the component for the planetary gear system,
- the raised areas extend in an axial direction, and
- wherein when viewed in a radial direction, the component has, in addition to the raised areas forming the pulse generator, further raised areas around the circumference of the component, which extend in the axial direction and form a second pulse generator.
