Abstract
An idler gear ( ) is mounted in a variable speed gear transmission ( ) on a rolling bearing crown ring ( ) whose first and second rolling elements ( ) are guided in a cage ( ) and have different diameters. The first and second rolling elements ( ) are of a same type, size ratios between the first and second rolling elements are defined so that, in an unloaded state, the larger diameter of the second rolling elements ( ) is such as to become equal to a diameter of the first rolling elements ( ) in an engaged state under radial loading, whereby a limit of elasticity of the second rolling elements ( ) having the larger diameter in the unloaded state is not exceeded.
