摘要： This application describes a motor that includes a housing, an output shaft, a conductive bearing, and a conductive component. The output shaft is disposed in the housing. A positioning hole is disposed on an end face of a first end of the output shaft, and the positioning hole is disposed coaxially with the output shaft. The conductive bearing is disposed in the positioning hole, and includes an inner ring, and an outer ring that is fixedly connected to the output shaft. One end of the conductive component is fixedly connected to the inner ring of the conductive bearing, and the other end is connected to the housing. In this application, the motor can output, by using the conductive bearing and the conductive component, charges accumulated in the output shaft, to eliminate a generated common-mode voltage.

摘要： A method of forming a bearing assembly includes providing a bearing unit configured to support a rotatable component relative to a stationary component, the bearing unit including a stationary bearing ring and a rotatable bearing ring, and overmolding a material onto a portion of a radial surface of the stationary bearing ring, the portion being less than an entire radial surface of the stationary bearing ring, for example less than 75% of the entire radial surface of the stationary bearing ring, to form the stationary component.

摘要： A non-locating bearing assembly includes a bearing unit configured to support a rotating component relative to a stationary component, and the bearing unit includes a first stationary bearing ring and a second rotatable bearing ring that is fixedly connectable to the rotating component. The bearing assembly also includes a bearing carrier to which the stationary bearing ring is attached in a rotationally fixed but axially displaceable manner, and the bearing carrier is configured to be fixedly connected to the stationary component.

摘要： An outer ring (26) for a bearing assembly includes an annular backing member (54) having a body, and an annular race member (50). The body has a first portion defining a radial inner surface (98) and a radial outer surface, and a second portion defining an axially-facing base surface (110) and a radially-facing end surface (118). The annular race member has a radial outer face (58) and a radial inner face, and a first axial end face and a second axial end face (70) that both extend between the radial outer face and the radial inner face. The annular backing member is in press-fit engagement with the annular race member such that the radial outer face of the annular race member engages the radial inner surface of the annular backing member and the second axial end face of the annular race member engages the axially-facing base surface of the annular backing member such that the members are unitized.

摘要： A bearing arrangement (30) comprises an inner support annulus (33), an outer support annulus (31), and a plurality of rollers (34) therebetween. At least one of the inner and the outer support annulus (33, 31) comprises one or more radially extending rigid supports (37) and one or more damping sectors (38a, 38b, 38c). The one or more rigid supports (37) are circumferentially interposed between one or more damping sectors (38a, 38b, 38c). Each damping sector (38a, 38b, 38c) comprises at least one damping member (39) comprising an elongate flexible member held rigidly at one or both ends thereof, such that vibrational movement of the inner or outer support annulus (33, 31) causes bending of the elongate flexible members (39).
