Patent ID: 7189183

Claim:
A stop washer ( 9 , 12 ) for planet gears of a planetary transmission, which stop washer ( 9 , 12 ) is arranged with a reception bore ( 9 . 1 , 12 . 1 ) on a planet gear axle ( 10 ) fixed in a planet gear carrier ( 1 ) and delimits said planet gears ( 6 ) in both axial directions, said planet gears ( 6 ) being mounted through a rolling bearing arrangement ( 11 ) for rotation about planet gear axles ( 10 ), a supply of lubricant to the bearing arrangement ( 11 ) being provided by an axial and a radial lubricant passage bores ( 10 . 1 , 10 . 2 ) of the planet gear axle ( 10 ) and by inner and outer axial openings of the stop washer ( 9 , 12 ), wherein each of the inner axial openings ( 9 . 2 , 12 . 2 ) communicates through a constriction ( 9 . 2 . 1 , 12 . 2 . 1 ) with the reception bore ( 9 . 1 , 12 . 2 ) of the stop washer ( 9 , 12 ), wherein the inner axial openings are arranged at least two equally spaced peripheral points of the stop washer ( 9 , 12 ), and wherein the outer axial openings ( 9 . 3 , 12 . 3 ) are arranged offset radially outwards between the inner axial openings ( 9 . 2 , 12 . 2 ), as viewed in radial direction, the inner axial openings ( 9 . 2 , 12 . 2 ) are situated in a region of rolling elements ( 11 . 1 ) of the bearing arrangement ( 11 ), while the outer axial openings (( 0 . 3 , 12 . 3 ) overlap at least a part of an end face of the planet gears ( 6 ).
