摘要:
The present disclosure provides a cage for bearings. The cage includes a pocket (2) for accommodating a rolling element of the bearing. The pocket (2) completely encloses the corresponding rolling element on a cylindrical surface where a pitch circle of the cage is located. The pocket has a roughly ellipsoidal shape. The ellipsoidal shape of each pocket (2) has a major axis L1 and a minor axis L2. The major axis L1 and the minor axis L2 satisfy the following relationship: L2

A double-row one-way bearing includes a bearing outer ring and a bearing inner ring coaxially arranged around a central axis. Spherical rollers are arranged between the bearing outer ring and the bearing inner ring. Wedges are radially arranged between the bearing outer ring and the bearing inner ring relative to the central axis, and spaced apart from the spherical rollers in the axial direction. Each wedge is provided with a groove at the side away from the bearing inner ring. A cage is coaxially arranged with the bearing outer ring and the bearing inner ring and provided with roller holding portions and wedge holding portions. The spherical rollers are respectively held in the roller holding portions and the wedges are respectively held in the wedge holding portions. An elastic limit ring passes through the groove of each wedge to apply a radially inward force to each wedge.

A rolling element bearing having a first ring element, a second ring element (3), a plurality of rolling elements arranged in a space between the first and the second ring elements such that the first and the second ring elements can rotate relative each other around a rotational axle. The bearing further includes a sealing ring for sealing off a circumferential opening of the space between the first and the second ring element. The sealing ring is connected to the first ring element and further arranged to rotate relative the second ring element of the rolling element bearing. The sealing ring provides a power generating system that provides at least one pick-up element arranged to generate electrical power when the rolling element bearing rotates. The power generating system is located completely within the circumferential opening of the space.

A method for producing a cage having a body with multiple pockets for rolling elements, the method providing: a) defining a cage basis geometry that provides a radial outer and/or inner surface for contacting a bearing ring and multiple surfaces of the pockets for contacting the rolling elements; b) defining a part of the radial outer and/or inner surfaces as being unalterable surfaces; c) calculating the cage stress distribution when applying a defined stress force from a mathematical model; d) defining cage volume sections where the stress is below a defined threshold; e) removing a part of the volume sections defined according to step d) taking into account the unalterable surfaces according to step b) and the surfaces of the pockets that are unalterable surfaces; f) defining the cage geometry with the removed volume sections; g) manufacturing the cage according to the geometry as defined according to step f).
摘要:
A rolling bearing includes an inner ring, an outer ring, a plurality of balls, and an annular cage. The cage has an annular portion provided on a first side in an axial direction with respect to the balls and a plurality of cage bars. Pockets that house the balls are each formed between the cage bars adjacent to each other in a circumferential direction. An axially-first-side side surface of the annular portion has a first surface that is inclined toward the first side in the axial direction as the first surface extends outward in a radial direction and a second surface provided outward of the first surface in the radial direction and positioned on the second side in the axial direction with respect to an extended virtual plane of the first surface.
摘要:
A bearing retainer for use in a bearing is provided. The bearing includes an inner ring, rolling elements and an outer ring. The bearing retainer includes a body. The body defines an inner periphery and an outer periphery of the body. The body further defines a plurality of inner walls. Each inner wall defines an opening extending from the inner periphery to the outer periphery of the body. The plurality of openings are adapted to receive one of the rolling elements. The inner walls are adapted to keep the rolling elements in a spaced apart relationship. At least one of the inner walls defines a aperture through the body. The aperture is adapted for storing lubrication therein.
摘要:
The invention relates to a rolling element bearing having at least one inner bearing inner and at least one outer bearing ring. Rolling elements are arranged between the inner ring and the outer ring, and the rolling elements are guided by a cage. To improve the lubrication of the bearing the invention proposes that the cage includes at least one opening, preferably a bore. The opening penetrates the cage from a radial inner surface to a radial outer surface.

A sealed compressor of the present invention comprises a sealed container (101) accommodating an electric component (105) and a compression component (106) and storing lubricating oil (102); wherein the compression component (106) includes a shaft (110) including a main shaft section (111), a main bearing unit (120), and a thrust ball bearing (132); wherein the main shaft section (111) is provided with a first oil feeding passage (150) to transport the lubricating oil (102); the thrust ball bearing (132) includes a cage (133), balls (134), an upper race (135) and a lower race (136), and the thrust ball bearing (132) is provided with a second oil feeding passage (160) communicated with the first oil feeding passage (150) and configured to feed the lubricating oil (102) to the raceway groove provided in at least one of the upper race (135) and the lower race (136), and a discharge passage (180) through which the lubricating oil (102) is discharged.
摘要:
A cage for a bearing for electric steering for a motor vehicle. The cage is designed to provide circumferential spacing of a row of roller elements, including an annular heel axially extended by separating portions that define cavities for the roller elements therebetween. The cavities radially extending from either side of the cage. The inner diameter of the separating portions is greater than the inner diameter of the annular heel.
