Background

A bearing is an important component of modern mechanical equipment, and a thrust roller bearing is one of them, and generally includes a shaft ring, a race, a cage, and rollers.

Thrust roller bearing especially thrust bearing, inconvenient direct and the less axial positioning lasso of wall thickness or retaining ring cooperation use in the use, because its race or the not enough yielding bearing failure that leads to of shaft circle intensity, even whole system can not normal operating, consequently, in order to avoid this kind of condition under the many situations, directly replace thrust roller bearing with the axle sleeve, but the relative motion of axle sleeve terminal surface and other work piece terminal surfaces is sliding friction this moment, it is all bigger to the axle sleeve and the work piece wearing and tearing that its contacted, the grit that sliding friction produced also can further influence the cleanliness of whole system, it is of a long time, can influence the life of whole system.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides a thrust roller bearing which is convenient to carry out axial positioning.

In order to realize the purpose, the utility model discloses a technical scheme is: the utility model provides a thrust roller bearing, includes race, seat circle, holder and roller, be equipped with annular rib on the terminal surface that the race kept away from the race, rib and the coaxial setting of race and the internal diameter of rib are unanimous with the internal diameter of seat circle, be equipped with on the outer wall of rib with seat circle terminal surface mutually perpendicular's reinforcing plate.

Among the above-mentioned technical scheme, the setting of rib and reinforcing plate can effectively solve the inconvenient direct and less axial positioning lasso of wall thickness or the retaining ring complex condition of thrust roller bearing especially thrust bearing, and the rib plays axial positioning's effect, makes the operation of system more stable, more smooth and easy, and has effectively prolonged the life of this system.

As a further setting of the utility model, the holder includes two annular support bodies and a plurality of pillars of connection support body, the roller is located between the double-phase adjacent pillar, and is adjacent it is protruding to be equipped with at least a set of locking on the opposite face of pillar respectively, it is protruding including setting up two locking on the opposite face corresponds both sides limit for a set of locking, the protruding face towards the roller of locking is the inclined plane tangent with the outer wall of roller.

Among the above-mentioned technical scheme, the locking is protruding can prevent that the holding from breaking away from at the roller between two adjacent pillars, makes roller steady operation, makes things convenient for the bearing equipment simultaneously, and the setting on inclined plane can play the effect of frizing, and it is even to guarantee the oil film on the roller, makes the bearing operation more smooth and easy.

As a further arrangement of the present invention, the reinforcing plate is at least three, and is rotationally symmetrical along the axis of the reinforcing portion.

Among the above-mentioned technical scheme, the reinforcing plate along reinforcing part rotational symmetry guarantees the reinforcing plate to the supporting effect of reinforcing part to make each part of reinforcing part receive balanced holding power, make the reinforcing part be difficult to produce the crack because of the atress inequality in the use.

As a further setting of the utility model, the reinforcing plate is right triangle, and two right-angle sides are located the terminal surface of seat circle and the outer wall of rib respectively.

Among the above-mentioned technical scheme, the shape of reinforcing plate guarantees the support effect when reducing whole quality, and can not exert an influence to the installation and the dismantlement of bearing.

As a further provision of the invention, the wall thickness of the reinforcement is less than the wall thickness of one half of the seat ring.

The present invention will be further described with reference to the accompanying drawings.

Detailed Description

When terms such as "upper" and "lower", "right" and "left" or similar relative expressions are used in the present embodiment, these refer only to the accompanying drawings and are not necessarily actual usage.

The specific embodiment of the present invention is shown in fig. 1-6.

The first embodiment is as follows: the embodiment is a plane thrust needle roller bearing, which comprises a shaft ring 01, a seat ring 02, a retainer 03 and rollers 04, wherein the rollers 04 are needle rollers, an annular reinforcing part 05 is arranged on the end surface of the seat ring 02 far away from the shaft ring 01, the reinforcing part 05 and the seat ring 02 are coaxially arranged, the inner diameter of the reinforcing part 05 is consistent with that of the seat ring 02, the wall thickness of the reinforcing part 05 is smaller than the wall thickness of one half of the seat ring 02, a reinforcing plate 06 which is perpendicular to the end surface of the seat ring 02 is arranged on the outer wall of the reinforcing part 05, the arrangement of the reinforcing part 05 and the reinforcing plate 06 can effectively solve the problem that the embodiment cannot be conveniently matched with an axial positioning ring or a check ring with smaller wall thickness, the reinforcing part 05 plays a role in axial positioning, so that the system runs more stably and smoothly, the service life of the system is effectively prolonged, at least three reinforcing plates 06 are rotationally symmetrical along the, guarantee the supporting effect of reinforcing plate 06 to reinforcing part 05, and make each part of reinforcing part 05 receive balanced holding power, make reinforcing part 05 be difficult to produce the crack because of the atress inequality in the use, reinforcing plate 06 is ten in this embodiment, reinforcing plate 06 is right triangle, and two right-angle sides are located the terminal surface of seat circle 02 and the outer wall of reinforcing part 05 respectively, the shape of reinforcing plate 06 guarantees the supporting effect when reducing whole quality, and can not exert an influence to the installation and the dismantlement of bearing, holder 03 includes a plurality of pillars 032 of two annular support bodies 031 and connection support body 031, roller 04 is located between two adjacent pillars 032, be equipped with at least a set of locking arch 0321 on the opposite face of adjacent pillar 032 respectively, in this embodiment, be equipped with a set of locking arch 0321 on the opposite face of adjacent pillar 032 respectively, a set of locking arch 0321 is including setting up two locking archs 0321 on the opposite face corresponding both sides, the protruding 0321 of locking is for the inclined plane 03211 tangent with roller 04's outer wall towards the face of roller 04, and the protruding 0321 of locking can prevent that the holding from breaking away from at the roller 04 between two adjacent pillars 032, makes roller 04 steady operation, makes things convenient for the bearing equipment simultaneously, and the setting of inclined plane 03211 can play the effect of frizing, guarantees that the oil film on the roller 04 is even, makes the bearing operation more smooth and easy.
