<p>#CMT# #/CMT# The unit (1) has two guide disks (2, 3) arranged parallel to one another and provided with perforations for receiving pins e.g. planetary pins (4) and riveted bolt pins, which have shoulders and pivots (5, 6), where the pivots are arranged on a front-side. The shoulders are provided with peripheral cutting edges (11, 12), and the pins are cut into the guide disks by the cutting edges. Circular-grooves formed concentric to holes are arranged in the guiding disks. #CMT# : #/CMT# An independent claim is also included for a method for manufacturing a planetary gear unit. #CMT#USE : #/CMT# Planetary gear unit. #CMT#ADVANTAGE : #/CMT# The planetary gear unit is designed in such a manner that it achieves a precise centering and arrangement of the pins. The shoulders are provided with peripheral cutting edges, and the pins are cut into the guide disks by the cutting edges, thus ensuring a play-free seating and a smooth surface for transmission of forces between the pins and the guiding disks. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a planetary gear unit. 1 : Planetary gear unit 2, 3 : Guide disks 4 : Planetary pins 5, 6 : Pivots 11, 12 : Peripheral cutting edges.</p> |
