Patent ID: 8555738

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 roller bearing ( 4 ), supported by a housing ( 23 ), supporting at least one of the plurality of loose gearwheels ( 3 ) of the variable-speed transmission for rotation about the main shaft ( 1 ), a gap ( 6 ) radially separating the roller bearing ( 4 ) from the housing ( 23 ) to provide radial movement between the at least one roller bearing and the housing ( 23 ), and the roller bearing ( 4 ) being axially braced, relative to the housing ( 23 ), by at least one spring element ( 5 ) which applies an axial force on the roller bearing ( 4 ) for dampening radial movement of the at least one bearing; and an inner bearing ring of the roller bearing ( 4 ) being located adjacent to and only directly engaging with the loose gearwheel ( 3 ) such that the inner roller bearing ring, of the roller bearing, is free from direct contact with any other support means for the roller bearing ( 4 ) while permitting axial movement of the loose gearwheel ( 3 ) relative to the roller bearing ( 4 ) during operation of the variable-speed transmission.
