Planetary gear, has planetary wheel carrier along with axial bearing provided at side of lubricant guiding region, which is designed with diameter enlarged at both sides as V- or U-shaped radial groove when viewed in cross-section

摘要

The gear (1) has an internal gear (4) mounted in a housing (2). Planetary wheels (5) are mounted at a planetary wheel carrier (7). A lubricant guiding region (15) is formed at the internal gear. Lubricant i.e. oil, from the housing drops into the guiding region. A roller bearing (3) i.e. inclined ball bearing, is provided at a side of the guiding region. The wheel carrier along with an axial bearing (8) is provided at another side of the guiding region. The guiding region is designed with a diameter enlarged at both sides as a V- or U-shaped radial groove when viewed in a cross-section.
