Planet carrier with crank, planetary gear and method for producing a cranked planet carrier

摘要

The invention relates to a planet carrier (1) with a first planet carrier cheek (2) made of sheet metal and a second planet carrier cheek (3) made of sheet metal, which are connected to one another in a rotationally fixed and axially fixed manner, the first planet carrier cheek (2) at least one tab (4) protruding on the outside. possesses, which protrudes into a through hole (9) of the second planet carrier cheek (3) and is deformed at the free end (8) without cutting in order to produce a bead (10) there, which has a larger cross-section than at least one axial dismantling the through hole (9), wherein the tab (4) has a crank (6) which aligns a surface (12) on the tab (4) so that it is on a contact surface (16) facing the first planet carrier cheek (2) second planet carrier cheek (3) is applied. The invention also relates to a planetary gear (27) with such a planetary carrier (1), with bolts / planetary bolts (23) being inserted into the planetary carrier (1), each of which supports at least one planetary gear (24). The invention also relates to a manufacturing method a planet carrier (1), in which a first planet carrier cheek (2) is punched out of a sheet metal plate in such a way that at least one tab (4) protrudes radially, which is bent in such a way that an axially protruding part (5) of the tab (4 ) set two bent areas (14 and 15) with a radially aligned contact area (13) in between, which together define a crank (6) which is supplemented by an integral rivet area (7) at the free end (8), the rivet area (7) is plastically deformed in order to have a bead (10) which is larger than the diameter of a through hole (9) of a second planet carrier cheek (3) into which the rivet region (7) is inserted.
