摘要:
A spacer designed for fitment between pairs of oblique rolling bearings (taper roller, ball bearings or similar) for enabling adjustable axial positioning of the same inside a support assembly, e.g. the hub-axle assembly of a vehicle suspension, the outer element of which presents a through hole for enabling adjustment of the spacer; which spacer consists of a pair of coaxial annular elements, the first engaged partially in sliding manner inside the second; a third annular element mounted externally and in axially mobile manner on the first element and designed to act as a shoulder for the second element; and locking mechanism for selectively securing the third element in a number of predetermined axial positions on and integral with the first element.

A sealing shield assembly for a rolling bearing has at least one ring with a seat comprising at least one essentially reinforcing member and an anchoring device made of an elastomeric material for securing the enforcing member in the bearing seat. The reinforcing member includes a peripheral annular sleeve portion shaped like a cylindrical sleeve, and an anchoring device which includes a radially elastically compressible sleeve section made of an elastomeric material. It is secured as a unit to the sleeve portion on a lateral coupling surface thereof, and is adapted to be interposed between the annular sleeve portion and the bearing seat. A plurality of axial grooves are on a separate lateral surface opposite the said coupling surface of the annular sleeve portion. The grooves extend from a continuous annular end portion of the elastomeric sleeve section to a point corresponding to a terminal rim of the annular sleeve portion interrupted by the grooves. The elastomeric sleeve section is capable of interacting radially with interference with the bearing seat.

A tight bearing suitable for exceptionally heavy duty conditions is supplied with side screens (14) made of a plate composition (16) which is restrained to the external ring (10) of the bearing and forms a labyrinth seal against the internal ring (11), and of plastic and elastomer materials (15) supplied with a lip (17) which creates friction on the internal ring (11); other plates (18) are assembled externally with respect to the screens (14) and are integral on the internal ring (11) and form a labyrinth seal (23) with the external ring (10) of the bearing; the internal face of the external plates (28) is lined with a layer of plastic and elastomer material (19) from which at least one lip (20) extends and forms an essentially axial seal against the external face of the plate (16) of the internal adjacent screen (14); the lip (20) of the layer (19) which lines the internal face of the external plates (18 ) slips and seals along a certain length (21) of bent conical converging internal plate (16) towards the internal ring (11) and towards the external part of the bearing.
摘要:
A taper roller bearing is described which has the particular feature of having the track of the inner ring capable of being inspected, such characteristic is obtained by means of a spacer cage the bridges of which extend both above and below the roller pitch circle identified by the axes of the rollers in such a way as to retain these latter in the pockets of the cage both on the outer ring side and on the inner ring side of the bearing; the cage in the pockets of which the rollers are snap-engageable, is removable together with the rollers of the track of the inner ring, being axially fixed to this latter by snap-engagement.

The hydraulic tappet comprises a cup-shaped body having a cylindrical side wall and a flat bottom wall, a piston element moving axially inside a cavity, formed in the said bottom wall and defining a first pressure chamber, an annular element of deformable material located on the outside of the said piston element and inside the said cylindrical wall, ducts for hydraulically connecting the said second chamber to the said first chamber and on which is fitted an on-off member, and a guide element moving axially inside the said cylindrical wall on the said cup-shaped body and having a side surface and a bottom wall.

A bearing designed to fit on a vehicle suspension of the "McPherson" type connects the vehicle wheels to the respective shock absorbers. The bearing is formed by an inner ring, an outer ring, and rolling bodies inserted between the rings, which are both provided with respective integral flanges. One of these flanges is provided with a projecting arm integral with the same and having a recess, able to be connected to a ball pin of a rocker arm of the suspension.

The process comprises at least a first phase for separating a plurality of particles of molten steel from a bath of molten steel, a second phase for subjecting these particles, while still in the fluid state, to a first system of forces acting on the outer surface of each of the said particles and to a second system of forces acting on each element of the body of each particle, the said two systems of forces being chosen in such a way that these forces tend to impart a substantially spherical form to each of the said particles, and a third phase for removing heat from the said particles sufficient to bring them substantially to the solid state.
摘要:
A protection and seal member for rolling bearings, arranged to be interposed between the inner race and the outer race of the bearing in order to isolate the rolling bodies from the surrounding ambient by providing a seal between the said races. The main characteristics of the protection member consists in that it is configured like a ring and is made of an elastomeric material so as to be capable of being snap-coupled with the outer race of the bearing on which it is mounted, and exerting on the outer surface of the inner race and on the inner surface of the outer race a sealing action between the outer ambient and the cavity formed between the said outer and inner races.
摘要:
A sealing device arranged to provide the seal for a fluid, in particular a liquid, between an ambient and the inside of a cavity comprised between a stationary member and a rotating member is described.The main feature of this sealing device is that it comprises two annular sealing elements, each of which has a plane annular surface substantially orthogonal to the axis of rotation of the rotating member and a cylindrical side surface orthogonal to the said plane annular surface, one of the said sealing elements being rigidly connected to the stationary member and the other to the rotating member, the said two plane annular surfaces being coupled and axial thrust means being provided which are arranged to keep coupled the said plane annular surfaces with a predetermined pressure, the said two cylindrical side surfaces of the two sealing elements having the same diameter and being substantially coincident.
