Embodiment Construction

[0014] figure 1 A partly shown planetary pin 1 is shown, which is arranged in a bore 2 of a likewise only partly shown guide plate 3 of a not shown planetary carrier. The planetary pin 1 has a longitudinal axis 1 a and an end face 1 b which, prior to final assembly, is approximately flush with the outer face 3 a of the guide disk 3 . A longitudinal bore 4 extending in the longitudinal direction 1 a and a transverse bore 5 are provided in the planetary pin 1 for supplying oil to the bearing points (not shown) of the planetary carrier. A groove 6 extending transversely to the longitudinal axis 1 a is formed in the end face 1 b and is penetrated by the longitudinal bore 4 . The arrangement shown to the left of the longitudinal axis 1 a in the figure shows the initial position of the planetary pin 1 , and the arrangement shown in the figure to the right of the longitudinal axis 1 a shows the initial position of the planetary pin 1 after being crimped by means of a caulking tool f...

Abstract

The invention relates to an arrangement of a pin (1) in a bore (2) of a disc (3), in particular a planetary gear pin (1) in a guiding disc (3) of a planet carrier, wherein the pin (1) is secured against turning by caulking with the disc (3). It is proposed that the pin (1) has at the extreme end at least one depression (6), in which material (3b) of the disc (3) can be caulked.

Description

technical field [0001] The invention relates to an arrangement of a pin in a hole according to the preamble of claim 1 and a method for positioning and fixing the pin according to the preamble of claim 8 . Background technique [0002] In the case of planetary gear carriers of planetary gears, it is known to insert pins, in particular planetary pins or riveting pins (for maintaining the distance), into bores of guide discs and caulk the discs. The pins of the planet gears have longitudinal and transverse holes, from which oil is supplied to the bearing points of the planet gears. The planet pin must therefore be calibrated in its angular position relative to the direction of rotation of the planet carrier before it is secured by caulking. Recesses are therefore provided in the respective bores of the planet carrier, into which grooves the material of the planet pins is caulked against rotation. A disadvantage in this case is that the inclination and deflection of the bore ...
