Patent ID: 8225688

Claim:
An assembly for reducing rattling noises in a variable-speed transmission, the assembly comprising: a main shaft ( 1 ); two countershafts; a plurality of loose gearwheels ( 3 ) being supported for rotation about the main shaft ( 1 ) and each of the plurality of loose gearwheels ( 3 ) being spaced radially relative to the main shaft ( 1 ); a transmission gear being engaged when a respective loose gearwheel ( 3 ) is rotationally fixed to the main shaft ( 1 ), at least one of the plurality of loose gearwheels ( 3 ) of the variable-speed transmission being supported on the main shaft ( 1 ) by at least one roller bearing ( 4 ), a gap ( 6 ) radially separating the roller bearing ( 4 ) from the main shaft ( 1 ), and the roller bearing ( 4 ) being axially braced, relative to the main shaft ( 1 ), by at least one spring element ( 5 ) which applies an axial force on the roller bearing ( 4 ); and an outer bearing ring ( 4 b ) of the roller bearing ( 4 ) being located adjacent to and only engaging with the loose gearwheel ( 3 ) so as not to be in contact with any other support means while still permitting relative axial movement of the loose gearwheel ( 3 ) relative to the roller bearing ( 4 ).
