    Abstract: A thrust collar is provided for preventing and limiting the axial movement of a rotating shaft and/or related bearing arrangement, principally in heavy engineering applications. The thrust collar (10) comprises first and second generally semi-circular body members (12,14), each body member having a first end (16) and a second end (20). A hinge arrangement pivotably connects the first ends (16) of the body members (12,14) to one another. The collar also includes a locking mechanism which has a locking member (40), and a locking rod (44) having a first rod end (46) pivotably attached to the second end (20) of the first body member (12), and a second rod end (50) pivotably attached to the locking member (40). A locking recess (42) is located adjacent the second end (20) of the second body member (14), with the locking member (40) being engageable in the locking recess so as to lock the second ends of the first and second body members (12,14) together.

    Abstract: A seal for a bearing (100) includes an annular retaining ring (12) defining a first radially innermost portion (12A) and a first radially outer end (12C); and a resilient ring (14) defining a second radially innermost portion (14A) and a second radially outer end (14C). The first radially innermost portion and the second radially innermost portion are aligned with one another and together define a securing root of the seal. The root is adapted to seat in a groove (22) of an inner ring of the bearing. The resilient ring projects radially outward from the annular retaining ring. The resilient ring is more flexible than the annular retaining ring. The second radially outer end defines a sealing surface adapted to slidingly engage an inner bearing surface of an outer ring of the bearing. The first radially outer end of the retaining ring terminates between the first radially innermost portion and the second radially outer end of the resilient ring.

    Abstract: A speed reducer is proposed which can maintain high efficiency by stably and inseparably keeping roller guiding bearings press-fitted on two eccentric disks of an input shaft. The input shaft (7) is provided coaxially with a stationary internal gear (3). The input shaft (7) carries the two eccentric disks (9) so as to be rotatable in the internal gear (3). The roller guiding bearings (11) are press-fitted on the radially outer surfaces of the respective eccentric disks (9). An output shaft (12) is provided coaxially with the input shaft (7) and has at the end thereof a cage (15) which is rotatable between the internal gear (3) and the eccentric disks (9). The cage (15) has roller receiving pockets (18) in two rows, each row of pockets being fewer in number than the internal teeth (4) of the internal gear (3). Rollers (19) are received in the respective roller receiving pockets (18). When the eccentric disks (9) rotate together with the input shaft (7), each roller (19) is adapted to mesh with the internal teeth (4) of the internal gear (3) one after another such that every time the input shaft (7) rotates once, each roller (19) moves circumferentially by a distance equal to one internal tooth (4), thereby rotating the output shaft (12) at a reduced speed. An annular protrusion (21) is provided between the two eccentric disks (9), and crimped protrusions (22) are formed on the ends of the respective eccentric disks (9) opposite to the axially facing ends of the respective eccentric disks (9). The crimped protrusions (22) and the annular protrusion (21) prevent axial movement of the bearings (11).

    Abstract: The purpose of the present invention is to provide a ball joint dust cover with good sealability that is able, even in low temperature environments, to limit the occurrence of gapping of the so-called small diameter opening and to effectively prevent infiltration of sediment and dust into the dust cover from the outside due to reduction in sealing performance at the small diameter opening. A ball joint dust cover made of a rubber-like elastic material in which: the ball head section formed on one end of a ball stud is held in a socket; the shaft of the other end of the ball stud is tightened and fixed to a knuckle; the large diameter opening of one end is fixed and held on the outer circumferential surface of the socket; the small diameter opening at the other end, to which a hard ring is integrally molded, is held on the shaft; and a membrane section, which connects the large diameter opening of the one end to the small diameter opening of the other end, is provided. The ball joint dust cover has a configuration wherein the inner circumferential surface of the hard ring is mated with the outer circumferential surface of a retainer, which has a cylindrical portion that is fitted and held on the outer circumferential surface of the shaft.
