Method for producing a shaft
A method for producing a shaft, in particular a balance shaft, crankshaft and the like, having at least one substantially annular bearing seat and at least one unbalance portion. The method includes the steps: provision of a shaft blank; formation of the at least one unbalance portion and of at least two opposite bearing seat side members by a forming process; and deformation of the at least two opposite bearing seat side members by a shell tool such that the bearing seat side members are bent together, whereby the at least one substantially annular bearing seat is formed.
BEARING OF A LEVER, WHICH IS PROVIDED WITH A PIVOT ARM, IN RELATION TO A PRESSURE PIECE
The proposal is for a bearing of a lever (1), which is provided with a pivot arm (1A), in relation to a pressure piece (7), having a race (45) on the lever side, said race being curved in a partially cylindrical manner, a race (35) on the pressure-piece side, said race being curved in a partially cylindrical manner, rolling elements (37), which roll on both races (45, 35) and are grouped together in a bearing cage (36), and having a radial projection (34), which is fixed in terms of rotation relative to one race (35) and forms a stop which limits the mobility of the bearing cage (36) in one circumferential direction. In order to refine the bearing in terms of assembly, the bearing comprises a pocket (50) or opening, which is arranged in the other race (45) or extends partially into said race, said pocket or opening extending only over a part of the race width and, at the transition to the curvature plane (E) of the race (45), forming a stop edge (52) which limits the mobility of the bearing cage (36) in the other circumferential direction.
METHOD OF LOCATING A BALANCER SHAFT BEARING
A method of locating a balancer shaft bearing of an engine, the method comprising the steps of: attaching a bearing retention clip to a balancer shaft bearing cap thereby defining a balancer shaft bearing cap assembly, the bearing retention clip comprising one or more retaining elements that extend at least partially across an opening of the balancer shaft bearing cap in an installed configuration; assembling the balancer shaft bearing cap and the balancer shaft bearing such that a portion of the balancer shaft bearing is received in the opening of the balancer shaft bearing cap; and restricting the movement of the balancer shaft bearing relative to the balancer shaft bearing cap upon engagement of the balancer shaft bearing with one or more of the retaining elements of the bearing retention clip.
FRICTION MINIMIZED SLIDING BEARING ARRANGEMENT
The present invention relates to a sliding bearing arrangement for supporting a shaft in a support element, comprising an inner bearing part with a sliding surface and comprising an outer bearing part with a sliding surface, whereas when the shaft is rotating around an axis, the sliding surface of the inner bearing part performs a sliding movement relative to the sliding surface of the outer bearing part. According to the invention, at least one of the sliding surfaces features at least one recess area which is extending in a circumferential direction of the surface over a circumferential angle (1, 2) and which is extending over at least 50% of the axial length of the sliding surface, and the recess area is dimensioned in such a way that over the recess area the clearance distance between the inner bearing part and the outer bearing part is increased.
SPHEROIDIAL JOINT FOR COLUMN SUPPORT IN A TUNED MASS DAMPER SYSTEM
A spheroidal joint for a tuned mass damper system includes a base having a concave seat and a lubricious liner secured thereto. The base defines a first mounting portion under the concave seat and a circumferential rim opposite the first mounting portion. The concave seat tapers radially outward to define a chamfer which terminates at a radially inner edge of the rim. The spheroidal joint includes an inner member that has a convex seat. The inner member has a second mounting portion extending from the convex seat and an indentation circumferentially extending around the inner member between the convex seat and the second mounting portion. The indentation cooperates with the chamfer for misalignment of the inner member relative to the base. The convex seat slidingly engages the lubricious liner.
Thrust sliding bearing
A thrust sliding bearing 1 includes: a synthetic resin-made upper casing 3 which has a vehicle body-side seat surface 10 for a mounting member 8 on a vehicle body side and an annular lower surface 2; a synthetic resin-made lower casing 5 on which an annular upper surface 4 opposed to the annular lower surface 2 and a spring seat surface 25 for a suspension coil spring 7 are integrally formed, and which is superposed on the upper casing 3 so as to be rotatable about an axis O of the upper casing 3 in an R direction; and a synthetic resin-made thrust sliding bearing piece 6 which is disposed in an annular gap 9 between the annular lower surface 2 and the annular upper surface 4, and has an annular thrust sliding bearing surface 51 which slidably abuts against at least one of the annular lower surface 2 and the annular upper surface 4.
Split bearing cage for rolling element bearing
A rolling-element bearing cage includes two axially spaced-apart side rings extending in a circumferential direction. Each side ring is split in the circumferential direction along at least one cutting line, thereby defining bordering surfaces on first and second bearing cage sections. A plurality of connecting bridges connects the side rings in an axial direction. First and second pairs of mutually-opposing first projections and corresponding first openings are disposed on the side rings along the bordering surfaces of the first and second bearing cage sections and fix the bordering surfaces to each other in at least first and second directions that are perpendicular to each other. A pair of a second projection and a corresponding second opening is disposed axially between the first and second pairs of first projections and first openings and fixes the bordering surfaces to each other in a third direction perpendicular to the first and second directions.
Synthetic resin-made sliding bearing
A synthetic resin-made sliding bearing 1 includes a synthetic resin-made upper casing 2 which is fixed to a mounting member on a vehicle body side; a reinforced synthetic resin-made lower casing 3 which is superposed on the upper casing 2 so as to be rotatable about an axis O in a circumferential direction R relative to the upper casing 2; a metallic reinforcing member 4; and a synthetic resin-made sliding bearing piece 5 disposed in a space S between the upper casing 2 and the lower casing 3.
Synthetic resin-made sliding bearing
A sliding bearing includes: an upper casing; a synthetic resin-made lower casing which is superposed on the upper casing so as to be rotatable about an axis in a circumferential direction relative to the upper casing; a synthetic resin-made sliding bearing piece disposed in an annular space between the upper casing and the lower casing; and a synthetic resin-made seal member for sealing respective other annular end portions, communicating with the outside, of a gap on an inner peripheral side and a gap on an outer peripheral side in a radial direction between the upper casing and the lower casing, the gap and the gap respectively communicating with the annular space at their one annular end portions.
Synthetic resin-made sliding bearing
A synthetic resin-made sliding bearing 1 includes a synthetic resin-made upper casing 2 which is fixed to a mounting member on a vehicle body side through a mounting member; a synthetic resin-made lower casing 3 which is superposed on the upper casing 2 so as to be rotatable about an axis O in a circumferential direction R relative to the upper casing 2; and a synthetic resin-made sliding bearing piece 5 disposed in a space 4 between the upper casing 2 and the lower casing 3.
