Description

The subject of the present invention is an axial fixation.

  gnons satellites by displacement of a body in the axis.

  By German patent DE-OS 25 03 518, an axial fixing of the pinion pinion axes is known in

  which, the ends of the axes are fixed to the holder

  satellite gnons by displacement of a body.

  Paï the German patent DE-PS 26 52 652, one knows an axial fixation of axes of planet gears,

  ge, and on the other hand, to improve the supply of lubricant

  In this. Indeed, the present invention provides a fi

  rise in that the satellite pinion axes are

  provided at both ends with transverse slots of a -

  depth equal to 2/3 the diameter of a ball and in at least one end of which an expansion ball is

  introduced, in a manner known per se, after mounting.

  The planet pinion axes being shaped as deep-drawn hollow axes the ends of which are provided

  transverse slots and one of the ends of which

  after assembly, an expansion ball, the manufacture of the door-satellite axis makes it possible to save material and labor, and for fixing, it is advantageous to use balls coming from the production of bearings with bil .the. The hollow satellite gear axes in connection with the transverse slots

  of their ends allow a good arrival of lubricant

  trusting to the bearings of the planet gears, without the need for drilling

transverse in the axis.

  The satellite pinion axes being spun at

  cold and provided in the area of their transverse slots

  blind holes, manufacturing is simpli-

  improved fixing and lubrication.

  The invention will be described below in more detail with reference to the accompanying drawings for which: - Figure 1 is a vertical section through a planet gear carrier with axial attachment according to the invention, and - Figure 2 is a representation enlarged by

  the axial fixing according to the invention of a carrier axis

  satellite pinions, - Figure 3 is a side view of a first embodiment of a pinion pinion axis obtained by deep drawing, - Figure 4 is a view of the axis of Figure 3 in the direction of arrow IV, - Figure 5 is a partial view of another embodiment of a cold-spun pinion pinion axis and, - Figure 6 is a view of the axis of Figure 5

in the direction of arrow VI.

  Satellite pinions 5 are mounted in rotation by means of a bearing 6 on an axis 4 of a satellite pinion carrier 1, between the side walls 2 and 3 thereof. The bearing 6 can preferably be

a needle bearing.

  The satellite pinion axes 4 are axes

  hollows obtained by deep drawing, the ends of which

  tees are provided with transverse slots 7.

  The tolerances of the receiving holes of the planet pinion axes 4 in the side walls 2

  and 3 of the satellite pinion carrier 1 are fixed in the

  next lesson: one end of the 4xe 4, on the left in the figure, is fixed, in a known way, by tight adjustment, while the other end of the axis 4, - on the right

  in the figure, is housed -in the hole in the wall la-

  plate 3 of the planet gear carrier by sliding adjustment

  be fitted by sliding adjustment at the two ends

  When the planet gears 5 with their rolls

  elements 6 and the usual wear washers 8 are mounted

  in the satellite pinion carrier l, a ball 9 is in-

  troduit in the right end of the hollow axis 4. the dimensions of the ball 9 are chosen in conjunction with the internal bore lO of the hollow axis 4, so that a tight fit of the right end of the 'axis

  hollow 4 is provided in the side wall 3 of the holder

satellite gnons 1.

  The depth of the transverse slots 7 reaches

  gaining about 2/3 of the diameter of the ball 9, it is ensured that the lubricant penetrating the hollow axis 4 will reach the bearing 6 by the radial elements of the slots

7.

  According to the embodiment shown in FIGS. 5 and 6, the planet pinion axis 4 ′ is a

  cold-drawn spindle provided in the area of its transverse slots

  versals 7 'of blind holes 10 sufficiently deep

  so that we can perfectly introduce the ball.
