Abstract

The invention relates to a roller bearing assembly. The invention also relates to a housing and a device with a rotary shaft. The device comprises a static structure, a rotor assembly, and a bearing assembly. The bearing assembly includes a first static race connected to the static structure, a first rotary race connected to the rotor assembly, a first rolling bearing element positioned between the first static structure and the first rotary race in a contact mode, a support member connected with the first static race, a second static race placed in the support member and connected to the support member, and a second rotary race placed in the support member. A second rolling bearing element is located between the second static race and the second rotary race.

Description

technical field [0001] The subject matter generally relates to rolling bearing element assemblies. Background technique [0002] Rolling bearing element assemblies such as ball bearings or roller bearings may generally include cages or other static structures separating the rolling bearing elements from each other. Such a configuration can generally result in energy losses at the bearing assembly. Such energy losses may result in heat buildup (such as heat generation), which may generally require increased cooling fluid (such as lubricant). Such energy loss can further reduce the structural life of the bearing assembly. Still further, a cage or other structure surrounding the rolling bearing element may have a low resistance to foreign matter, such as hard particles, between the cage and the rolling bearing element. [0003] Accordingly, there is a need for a bearing assembly that reduces energy loss, reduces heat buildup, reduces required cooling fluid or lubricant, prol...
