Rolling bearing and spindle apparatus for machine tool
A rolling bearing includes an inner ring having an outer surface, an outer ring having an inner surface, a plurality of rolling elements rotatably disposed between the inner ring and the outer ring, and a retainer for retaining the rolling elements. The retainer is made of a resin material and is positioned with respect to the inner surface of the outer ring or the outer surface of the inner ring. The retainer includes a pair of annular portions axially arranged in parallel and a columnar portion coupling the annular portions. Then, the rolling bearing satisfies the following expression: .[.AI=LH.sup.3/dm≥0.025.]. .Iadd.LH.sup.3/dm.sup.2≥0.025 mm.sup.2 .Iaddend.in which H is a radial length of a section of the annular portion, L is an axial length of the same, and dm is PCD of the rolling element.
SPRING DAMPER BEARING AND SPRING DAMPER BEARING ASSEMBLY
A spring damper bearing includes a bearing cap, a guide ring and a thrust bearing. The bearing cap and the guide ring are connected together and surround the thrust bearing. The bearing cap includes an annular main body portion and a barrier part which is located on an inner circumferential side of the main body portion. The barrier part has an annular shape and includes an outer circumferential end connected to the main body portion and an inner circumferential end which extends out from the outer circumferential end and is away from the main body portion. The inner circumferential end is nearer than the outer circumferential end to the lower axial side and the inner radial side of the spring damper bearing.
METHOD FOR PRODUCING A BALL JOINT AND/OR A CHASSIS COMPONENT, AND CHASSIS COMPONENT OF THIS TYPE
A method for producing a ball joint (18) and/or a chassis component (19), in which a joint ball (1) is made, in which the joint ball (1) is placed in an injection-molding die, in which the joint ball (1) is partially overmolded with a plastic material, and in which the plastic material is hardened to form an injection-molded joint housing (2) for the joint ball (1). A joint housing (2) is formed using the joint ball without a joint pin (10), and the joint ball (1) has respective pole surfaces (3, 4) on two sides remote from one another.
Ball-and-socket joint for chassis parts of a motor vehicle
A ball joint including a ball stud which has a spherical portion, two bearing shells that are arranged on the spherical portion such that there is a small gap between the two bearing shells, and a housing that is made from plastic in one piece and encloses the two bearing shells such that the two bearing shells are urged against the spherical portion by the housing.
Assembly for a bearing and methods of making and using the same
An assembly comprising: a core in the form of a toroid; and at least one washer overlying the core, the washer comprising a polymer, wherein the washer has an arcuate cross-section so as to have a shape complementary to the core.
Reinforced casing for food applications
Casing of a bearing unit for food applications, made of polymeric material and provided internally with a spherical seat for housing the bearing unit, the casing having a reinforcement in the form of a metal ring co-moulded inside the casing and accommodated around the spherical seat of the casing.
LENGTH-ADJUSTABLE STEERING SHAFT FOR A MOTOR VEHICLE, AND PROFILED SLEEVE FOR A STEERING SHAFT
A length-adjustable steering shaft for a motor vehicle may include a hollow outer shaft with an unround inner cross section, in which an inner shaft is received in a torque-locked and axially movable manner. A profiled sleeve may be arranged between the inner shaft and the outer shaft, and the profiled sleeve may have a fastening portion connected to the inner shaft. The inner shaft may be configured at least in part as a hollow shaft that has an interior that is open towards the end that is inserted into the outer shaft. To reduce the outlay in terms of production and assembly, the fastening portion may extend from the end into the interior of the inner shaft and is connected to an inner surface of the interior.
Insert for a ball joint in a motor vehicle, ball joint or link having an insert of this type, and method for producing an insert of this type, a ball joint of this type or a link of this type
An insert for a ball joint (19) in a motor vehicle. The insert having a first part-structure (6) for making at least partial slide-bearing contact with a joint ball (2). The first part-structure (6) can be connected, by over-molding, to a joint socket (17) and/or to a joint housing (18). The insert (1) can be positioned and/or handled to cover a pole surface, to increase the extraction force, the insert (1) has an open part-structure (20) such that a cage-like configuration can be produced for surrounding the joint ball (2).
Polymer joining ring for a bearing assembly
The present disclosure discloses a polymer joining ring for a bearing assembly and is configured to retain a first inner ring and a second inner ring together to the bearing assembly. The polymer joining ring includes an outer surface and an inner surface. The outer surface includes a W or E shaped geometry throughout and includes a pair of flanges extending radially outwards at corners from outer surface, and a semi-circular protrusion extending at middle of the polymer joining ring. The pair of flanges are placed in tapered narrow grooves of the first inner ring and the second inner ring, and the semi-circular protrusion is placed in a triangular shape space produced between the first inner ring and the second inner ring can be tightly connected to each other. The joining ring is made of a polymer material that facilitates ease in assembling and accurate positioning of the inner rings.
Sliding bearing
Provided is a sliding bearing capable of reducing the number of components and reducing costs. This sliding bearing (1) is provided with; an upper case (2); a lower case (3) combined with the upper case (2); and an annular dust seal-integrated center plate (8) that has a dust seal part (6) for covering a gap between the upper case (2) and the lower case (3), is disposed between the upper case (2) and the lower case (3), and enables relative rotation between the upper case (2) and the lower case (3). The dust seal-integrated center plate (8) is integrally formed with the lower case (3).
