摘要： To solve both axial and rotational constraint problems in turbochargers with rolling element bearings (REBs), a REB sleeve or outer race is mounted to the bearing housing in a way that is not axially and radially rigid, thus allowing for oil damping films both radially and axially. At the same time, the REB sleeve or outer race is held so that the REB sleeve or outer race does not rotate relative to the bearing housing. This dual purpose is achieved using an anti-rotation ring and a damping ring. The anti-rotation ring includes at least one anti-rotation feature for engaging the bearing housing and at least one anti-rotation feature for engaging the REB cartridge, preventing rotation of the REB cartridge sleeve or outer race. The damping ring axially locates the REB cartridge and dampens axial movement and cushions axial thrust.

摘要： A halved sliding bearing (1) has a recess (7) formed in a circumferential direction from an outer peripheral edge of a mating surface (5) of a semi-cylindrical bearing main body (3). To prevent formation of a burr to an inside of the recess (7) during formation of the mating surface (5), an entirety of at least one edge segment of a peripheral edge of the recess (7) opening on a circumferential end surface of a semi-cylindrical member (23) as an unprocessed body of the bearing main body (3), the at least one edge segment intersecting with an axial direction of the member (23), is chamfered. The mating surface is formed by cutting the circumferential end surface such that a cutting blade (31) firstly reaches the chamfered edge in the peripheral edge of the recess (7). Thus, the bearing main body is produced.

摘要： To solve heat soak and reduced heat rejection capability problems in turbochargers with rolling element bearings (REBs), the REB cartridge is mounted to the bearing housing in a way that is not rigid, thus allows for an oil damping film, but, at the same time, the REB cartridge is held both axially, to transfer thrust loads to the bearing housing, and rotationally, so that the REB cartridge does not rotate relative to the bearing housing, using male or female features in the REB and corresponding female or male features associated with the bearing bore or the turbine face of the bearing housing closure.

摘要： Disclosed is a fluid dynamic bearing device in which it is possible to prevent detachment of the shaft member reliably and at low cost without involving any increase in the device size. In a thrust bearing portion T, the lower end surface of the shaft member is held in contact with a thrust plate, and the shaft member is rotatably supported in the thrust direction. Protrusions extending radially inwards are provided on a sealing portion attached to an opening of the housing, and these protrusions are engaged with a small diameter portion formed on the outer peripheral surface of the shaft member, thereby preventing the shaft member from coming off.

摘要： A motor includes a bearing having first and second end faces spaced along a longitudinal axis thereof. A longitudinal hole extends from the first end face through the second end face and includes a recessed portion having first and second peripheral edges respectively contiguous to the first end face and an inner periphery of the longitudinal hole. A retaining member is mounted to the first end face. A radial spacing between an inner periphery of a through-hole of the retaining member and the inner periphery of the longitudinal hole of the bearing in a radial direction is not greater than an axial spacing from the first end face to the second peripheral edge. The retaining member further includes a plurality retaining plates. The recessed portion provides a space sufficient to allow deformation of the retaining plates when inserting a shaft through the through-hole into the longitudinal hole of the bearing.

摘要： A sliding bearing shell is described, comprising at least one holding cam (4) which is provided in the region of the dividing surface (2), projects beyond the back (3) of the shell and forms a deformation section of the sliding bearing shell (1) which extends over only a part of the thickness of the shell. In order to provide advantageous constructional conditions it is proposed that the deformation section consists of a tongue (5) which is cut out and bent out partly from the sliding bearing shell (1) through an indentation (6) starting from the dividing surface (2).

摘要： In a bearing assembly, a shaft is inserted into a sleeve, and a lower end of the shaft is attracted to a magnet chip which is held by an auxiliary yoke. A retaining member and an auxiliary washer are sandwiched between a lower end surface of the sleeve and a contact portion of the auxiliary yoke so as to retain the shaft in the sleeve. The auxiliary washer has an inner diameter larger than that of the retaining member and a maximum diameter of the lower end of the shaft.
