摘要： A shaft rotates within a housing on a double row tapered roller bearing and remains extremely stable at all temperatures, even though the housing is formed from a light weight metal having a significantly greater coefficient of thermal expansion than the metal of the bearing. To this end, the housing contains a bore defined by a cylindrical surface and a conical surface which flares away from the cylindrical surface and opens out of one face of the housing. The bearing has two cones which surround the shaft, a unitary or double cup which fits into the bore of the housing, and tapered rollers arranged in two rows between the cones and cup. The double cup on its exterior has a cylindrical surface which fits into the cylindrical surface of the housing bore and a flange provided with a beveled face which is against the conical surface of the housing bore. In addition, the cup has a threaded end which projects axially beyond the cylindrical surface of the cup engages a nut that is on the housing at the end of the cylindrical surface of the bore. The nut draws the beveled surface of the cup flange tightly against the conical surface of the housing bore. With an elevation in temperature, the housing expands axially and causes the flange to seat even more tightly against the conical surface of the housing, so that the cup remains firmly positioned, both radially and axially, in the housing, even though the cylindrical surface of the housing bore enlarges with respect to the cylindrical surface on the housing.
摘要翻译：轴在双列圆锥滚子轴承内的壳体内旋转，并且在所有温度下保持非常稳定，即使壳体由具有比轴承的金属显着更大的热膨胀系数的轻质金属形成。为此，壳体包含由圆柱形表面和圆锥形表面限定的孔，锥形表面从圆柱形表面张开并且从壳体的一个表面开口。该轴承具有围绕轴的两个锥体，一个装配到壳体的孔中的整体或双杯，以及在锥体和杯之间布置成两排的锥形辊。其外部的双杯具有圆柱形表面，其配合到壳体孔的圆柱形表面中，并且具有凸缘，凸缘设置有抵靠着壳体孔的圆锥形表面的斜面。此外，杯具有轴向突出超过杯的圆柱形表面的螺纹端接合在孔的圆柱形表面的端部处在壳体上的螺母。螺母将杯形凸缘的斜面紧紧地压靠在壳体孔的锥形表面上。随着温度升高，壳体轴向膨胀并且使得凸缘更紧密地抵靠壳体的锥形表面，使得杯子在径向和轴向上保持牢固地定位在壳体中，即使圆柱形表面壳体相对于壳体上的圆柱形表面增大。

摘要： The present invention provides a bearing device reliable of shielding any material or fluid from moving between a fluid passage within a fluid system housing and an outside of the housing. In the above bearing device, a roller bearing (12) equipped with sealing plates (17) is fitted into a coupling bore (11) in an intake pipe (1) serving as the housing so that the roller bearing (12) can bear a shaft (6) of a butterfly valve disposed in a fluid passage (2) within the intake pipe (1). The outer race (13) and the inner race (14) of the roller bearing (12) are formed with annular grooves (21, 22), respectively, and O-rings (23, 24) are engagingly arranged on the interior of the annular grooves (21, 22), respectively. With the bearing device having this structure, the O-rings (23, 24) can prevent air, etc. from permeating into the intake passage (2) even though clearance (a, b) occurs in the engaged sections due to a dimensional error, difference in thermal expansion, etc.

摘要： A vehicle transmission is provided having a housing that includes a support with an opening. The transmission also has a shaft with an axis of rotation and an end portion disposed within the support opening. A floating bearing assembly is arranged between the housing and the end portion so that the bearing assembly supports the end portion within the support opening thereby permitting the shaft to rotate about it axis within the support opening. The bearing assembly is movable along the axis of rotation relative to the housing to permit the shaft to move along the axis of rotation. An expansion member is arranged between the end portion and the housing to expand and contract with changing temperatures and maintain a desired end play tolerance between the end portion and the housing.

摘要： Method and apparatus for automatically dynamically adjusting prestressed bearings of shaft are provided. The apparatus comprises a sleeve assembly having outer and inner sleeves sandwiched between the bearings. An inner diameter of outer sleeve is smaller than an outer diameter of inner sleeve. Hence, outer and inner sleeves are fitted together after cooling. Further, inner sleeve is compressed by the outer sleeve to extend axially. During rotation of shaft, the axial extension of inner sleeve is reduced because the radial expansion of outer sleeve is larger than that of inner sleeve due to an thermal expansion coefficient of outer sleeve larger than that of inner sleeve. This can reduce prestress of bearings without degrading a rigidity thereof.
摘要翻译：提供了自动动态调节轴预应力轴承的方法和装置。该装置包括套筒组件，其具有夹在轴承之间的外套筒和内套筒。外套筒的内径小于内套筒的外径。因此，冷却后将外套筒和内套管装配在一起。此外，内套筒被外套筒压缩以轴向延伸。在轴的旋转期间，由于外套筒的热膨胀系数大于内套筒的热膨胀系数，外套筒的径向膨胀大于内套筒的径向膨胀，所以内套筒的轴向延伸减小。这可以减少轴承的预应力而不降低其刚度。

摘要： A unit consisting of a bearing equipped with a data sensor device and a housing in which the bearing is coupled. The bearing consists of an inner turning collar designed to be attached to a turning body, an outer fixed collar coupled to the housing, and rolling bodies positioned between them. The data sensor device consists of a coder that generates magnetic impulses attached to the turning collar and, attached to the fixed collar, a sensor equipped with at least two sensitive components capable of detecting such impulses. The housing is designed to permit said bearing to be locked radially and to lock the bearing axially in one direction. The sensor is made in monoblock construction and configured such that the bearing is locked at least in the other direction.

In one embodiment, a bearing assembly (10) includes first and second bearing members (12, 14) adapted for movement relative to each other. The first bearing member includes an outer layer (24) that is adapted to wear in response to the relative movement between bearing members, and an inner layer. The inner layer includes a base portion (28) having a first hardness and a plurality of spaced apart wear indicating regions (30) having a second hardness, whereby the first hardness and second hardness are different. The wear indicating regions are adapted to produce a vibration after sufficient wear of the outer layer.
