Embodiment Construction

[0029] figure 1 A longitudinal section through a first shaft 10 and a second shaft 20 of a transmission, not further shown here, is shown. The central axis 11 of the shaft 10 and the central axis 21 of the second shaft 20 extend parallel to each other. Arranged on the first shaft 10 is a first gear wheel 30 which meshes with a second gear wheel 40 seated on the second shaft 20 .

[0030] exist figure 1 In the embodiment, the first gear 30 and the first shaft 10 are integrally constructed. The first gear wheel 30 has toothing 32 on a circumference 31 . image 3 The individual teeth 33 of the toothing 32 can be seen in the figure. as from figure 1 As can be seen in , the tooth portion 32 has a dedendum circle diameter d F and addendum circle diameter d K .

[0031]The first gear wheel 30 surrounds in the radial direction a shaft cavity 12 for receiving a guide bearing (not shown here). Beside the first gear wheel 30 in the axial direction, a coupling ring or plug cone 5...

Abstract

The present invention relates to a transmission which is provided with a first gear (30) and at least one second gear (40). The first gear is provided on one shaft (10). The second gear is matched with the first gear (30) through engaging, wherein, oil or analog is used as lubricant between the engaged gears (30,40), wherein, an oil guiding-out device is provided. At least one part of the oil is guided out radially from the engaged gears (30,40) inwards to a central axis (11) of the shaft (10) through the oil guiding-out device. According to the invention, a sealing device is provided at one axial side surface (34) of the first gear (30). The oil guiding-out device comprises at least one oil channel (60) which is radially closed outwards. The oil channel is provided in the axial side surface (34) or at the axial side surface (34). The oil which is provided in front of the sealing device (5) or at the sealing device (52) can be guided out through the oil channel.

Description

technical field [0001] The invention relates to a transmission having a first gear disposed on a shaft and at least one second gear in meshing engagement with the first gear, wherein in these meshing Oil or the like is used as lubricant between the gears, wherein an oil discharge device is provided through which at least a portion of the oil is discharged radially inwards from the meshing gears in the direction of the central axis of the shaft. Background technique [0002] A motor vehicle transmission is known from DE 2918601 A1, in which an input shaft carries a first gear which meshes with a second gear on the drive shaft of the transmission. The output shaft of the transmission is arranged coaxially with respect to the input shaft and is supported on the input shaft via a guide bearing at the end facing the input shaft. The guide bearing is seated here in a shaft cavity which is open at the end and which is surrounded in the radial direction by the first gear wheel. Oi...
