TL;DR: In this article, the bearing seat between the roller bearing and the transmission-side stop is arranged to prevent the bearing from bumping against the stop during assembly and thereby to compensate for thermal expansion during operation to allow axial displacement of the rolling bearing.
Abstract: Connection arrangement (1) for connecting a motor to a transmission (2), with a housing (3) with a bearing seat for a roller bearing (6) and an adapter (5) rotatably mounted by the roller bearing (6) for receiving the motor shaft on the motor side and to drive the gearbox (2), the roller bearing (6) being axially displaceable in the bearing seat up to a stop arranged on the gearbox side in order to avoid mechanical overdetermination of the mounting of the adapter (5) and the mechanical tension associated therewith and in which Bearing seat between the roller bearing (6) and the transmission-side stop a resilient spacer (12) is arranged, which is sufficiently firm to prevent the roller bearing (6) from bumping against the stop during assembly and thereby to compensate for thermal expansion during operation to allow axial displacement of the rolling bearing (6) in the direction of the stop.

TL;DR: In this article, the authors proposed a method to prevent deterioration of accuracy based on thermal displacement of a main spindle, by a method wherein an inner and outer races, whose space between them is sealed, are made of a bearing material whose conductivity is poor and a lubrication hole and oil drain hole for lubricating oil are provided on the outer race.
Abstract: PURPOSE:To prevent deterioration of accuracy based on thermal displacement of a main spindle, by a method wherein an inner and outer races, whose space between them is sealed, are made of a bearing material whose conductivity is poor and a lubrication hole and oil drain hole for lubricating oil are provided on the outer race. CONSTITUTION:An inner and outer races 1, 2 are made of a bearing material, whose thermal conductivity is poor, such as fine ceramics, a roller 3 is arranged between the inner and outer races 1, 2, a lubrication hole 5 for lubricating oil is provided on one side out of both side inner circumferential surfaces adjoining to a raceway groove 4 of the outer race 2, an oil drain hole 6 is provided on the other side of the same, and an annular space between the inner and outer races 1, 2 is sealed by sticking annular shield plates 7 on the inner circumference of both ends of the outer race 2. In consequence of the above, heating of the inside of a bearing is hard to transmit to a main spindle and housing of a machine tool and, moreover, the inside of the bearing is cooled by the circulating lubricating oil or the lubricating oil and air.

TL;DR: In this article, a method of manufacturing a bearing device having a housing into which a bearing bush is press-fitted is described, which includes forming a tapered shape of a bearing hole, and fitting the bearing bush into a bore of the housing having a uniform inside diameter.
Abstract: A method of manufacturing a bearing device having a housing into which a bearing bush is press-fitted. This method includes forming a tapered shape of a bearing hole of a bearing bush, and press-fitting the bearing bush into a bore of the housing having a uniform inside diameter.

06 Jun 1995TL;DR: A flexural pivot bearing as mentioned in this paper consists of a pair of members with opposed close-spaced faces which are joined by a web of microscopic thickness in a plane intersecting the faces.
Abstract: A flexural pivot bearing includes a pair of members with opposed close-spaced faces which are joined by a web (29), of microscopic thickness, in a plane intersecting the faces. These members and the web are comprised of an integral body (27) of substantially uniform material, and the members are adapted for pivoted mutual flexure about a pivot axis aligned along the web.

TL;DR: There is insufficient clinical data to demonstrate the overall superiority of any one bearing couple for all total hip cases, so it is reasonable to individualize the choice of bearing surface.
Abstract: There is insufficient clinical data to demonstrate the overall superiority of any one bearing couple for all total hip cases. It is therefore reasonable to individualize the choice of bearing surface. The fundamental exercise in choosing a bearing surface is maximizing the benefit to risk ratio. There are at least 3 perspectives to consider: the patient's, the surgeon's, and that of the health care delivery system. The following question should be addressed on a patient-by-patient basis: what available bearing is most likely to meet the needs of this patient, with an acceptable risk of revision surgery during his or her lifetime, is accepted in my community, and is there a means to pay for it?
