Abstract:
A method for producing a planet carrier for a planetary gear which has one sun gear, at least one ring gear, at least one planet gear and one input shaft, wherein said planet carrier has one spider shaft (1) and two guide plates (2, 3) interconnected in parallel and disposed spaced apart and parallel to each other, the method comprising the steps of:producing said guide plates (2, 3) as precision blanked parts with each of two guide plates (2, 3), situated upon said spider shaft (1), being interconnected by a press during a one stroke pressing process, with a number of rivets (4) equaling a number of planets to be supported by the planet carrier such that in shoulders (9) of said rivets (4) defined by tappets (5), annular projections (8) are integrated which concentrically surround a longitudinal axis of said rivets (4) and impinging the guide plates (2, 3), via a tool (6) of the press, in a direction of said shoulders (9) which are provided with an annular projection (7) having a similar geometry as the annular projection (8) and is disposed exactly opposite to the annular projection (8) of said shoulders (9) so that during the riveting step inadmissible deformation of said guide plates (2, 3), radially outside said annular projections (7, 8), is prevented from occurring.
