Abstract

PURPOSE:To narrow a space between two ball bearings so sharply as well as to simplify the assembly of a bearing by inserting a nearly cylindrical rubber ring into an interval between these two ball bearings in a state of compression, and constituting it so as to apply preload to the ball bearing with reaction force by deformation of the rubber ring. CONSTITUTION:A cylindrical rubber ring 5 is inserted into a space between an outer ring 3a of a ball bearing 3 and another outer ring 4a of a ball bearing 4 in compression after the ring 5 is turned into a state of not being contacted with a turning center shaft 1, and preload is applied to these ball bearings 3, 4 with reaction force against elastic deformation of the rubber ring 5. Thus, as a preload means for these ball bearings 3, 4, it is changed to the rubber ring 5 from the conventional coil spring, so that a space between both ball bearings 3, 4 can be sharply narrowed as compared with the conventional one. In addition, since the rubber ring 5 is insertable into the space between these outer rings 3a, 4a from the side of the ball bearing 4 smaller in its diameter, the assembly of a bearing device can be remarkably simplified.
