Embodiment Construction

[0029] specific implementation plan

[0030] figure 1 A partial longitudinal sectional view of the planetary gear 1 according to the invention is shown. The planetary gear 1 has two planetary gear sets, which are constructed from a planetary carrier with a plurality of planetary gears 4 or 5, the planetary carrier comprising two planetary carrier halves 2, 3, the planetary wheels are respectively connected via planetary pins 6 is connected to the respective planetary carrier halves 2 and 3 in a rotatable manner. In this case, the planet gears 4 mesh with the sun gear 7 and the planet wheels 5 mesh with the sun gear 8 . Sun gears 7 , 8 are radially inward relative to planetary gear 1 compared to planet gears 4 , 5 . The drive wheel 9 in the form of an external ring gear 10 is radially further outward than the planet wheels 4 , 5 , which is fixedly connected to the respective planet carrier half 2 , 3 via welds 11 or 12 , by means of This enables torque transfer.

Abstract

The invention relates to a spur gear differential (34) with a planetary carrier (2, 3) which is fixedly connected to the bearings (13, 14) in a rotationally fixed manner and which has and connecting rivets for the planetary pins (6) ( 38) holes (39, 40), wherein the hole soffits (41) completely surrounding each hole (39, 40) are formed from the material of the planet carrier (2, 3), wherein the bearings (13, 14) have Bearing ring (35), wherein at least one region of the inner edge of the planet carrier (2, 3) is arranged radially further outward than the outer edge of the toothing of the sun gear (7, 8).

Description

technical field [0001] The invention relates to a spur gear differential having a planetary carrier which is fixedly connected to bearings in a rotationally fixed manner and which has holes for planetary pins and connecting rivets, wherein each hole is completely surrounded by the material of the planetary carrier A bore soffit in which the bearing has a bearing ring. Background technique [0002] An improved bearing inner ring for centering a planet carrier is known from DE 10 2012 206 449 A1. This publication discloses a planetary transmission, such as a differential transmission, which has a planetary carrier, on which planetary gears are rotatably connected, the planetary gears mesh with at least one sun gear, wherein the planetary carrier Can be connected to a drive wheel, such as an externally toothed ring gear, wherein a bearing (such as a rolling bearing) with an inner bearing ring and an outer bearing ring also positions the planet carrier axially and / or radially i...
