BEARING ASSEMBLIES, APPARATUSES, AND MOTOR ASSEMBLIES USING THE SAME

摘要

Bearing assemblies, apparatuses, and motor assemblies using the same are disclosed. In an embodiment, a bearing assembly 100 includes a plurality of superhard bearing elements 108 distributed circumferentially about an axis 124. At least some of the superhard bearing elements 108 may include a first end surface 118, a second end surface 120 generally opposite the first end surface 118, a first side surface 114 extending between the first end surface 118 and the second end surface 120, a second side surface 116 generally opposite the first side surface 114, and a bearing surface 122 extending between the first end surface 118, the second end surface 120, the first side surface 114 and the second side surface 116. Such superhard bearing elements 108 may also include a ramped feature 130 negatively sloping away from the bearing surface 122. The bearing assembly may further include a support ring 102 that carries the plurality of superhard bearing elements 108.
