The product is formed by punching a precision rolling steel strip, various precision indexes meet the requirements of working conditions, the production efficiency is very high, and the production cost is greatly reduced. The plastic protection structure is more accurately guided, and the working noise is reduced; the thrust roller path is formed by precise high-speed punch forming, the production process is very stable, the punching speed reaches 300 pieces/minute, the production cost is very low and is 30 percent of the production cost of the original grinding product. The plastic protection structure reduces the working noise of a product worker and improves the customer experience.

Description

Lightweight thrust bearing

Technical Field

The utility model relates to a bearing especially relates to a lightweight thrust bearing.

Background

The traditional product adopts metal to make and keeps ware weight big, keeps the wearing and tearing of ware and cooperation hole axle big when using, leads to the product to become invalid and easily produces serious noise. The retainer made of composite material is changed, the weight is reduced, the abrasion between the nylon retainer and the matching hole shaft is small, the probability of product failure can be effectively reduced, the noise is reduced, and a better mute box is provided for an automobile.

SUMMERY OF THE UTILITY MODEL

The utility model aims at: each precision index satisfies the operating mode requirement, but production efficiency is very high, and manufacturing cost greatly reduced adopts punching press thrust raceway to replace and grinds processing thrust raceway to reach the purpose that improves production efficiency, reduction in production cost a lightweight thrust bearing.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a thrust bearing of lightweight, includes the holder, sets up the steel ball group in the holder and establishes the outside thrust raceway circle subassembly of steel ball group, its characterized in that: the retainer is by cyclic annular board component and set up a plurality of steel ball pockets that set up in cyclic annular board component ring circumference, ball pocket in be equipped with the interior clamping face of ball contact, the upper and lower extreme of interior clamping face respectively be equipped with an oiling groove, the inner circle of thrust raceway ring subassembly in set up with the thrust joint recess between the axle.

And a thrust clamping groove between the thrust raceway ring assembly and the shaft is formed in the inner ring of the thrust raceway ring assembly.

An inner connecting groove is arranged in the inner ring of the retainer.

The utility model has the advantages that: the product is formed by punching a precision rolling steel strip, various precision indexes meet the requirements of working conditions, the production efficiency is very high, and the production cost is greatly reduced. The plastic protection structure is more accurately guided, and the working noise is reduced; the thrust roller path is formed by precise high-speed punch forming, the production process is very stable, the punching speed reaches 300 pieces/minute, the production cost is very low and is 30 percent of the production cost of the original grinding product. The plastic protection structure reduces the working noise of a product worker and improves the customer experience.

The present invention will be described in more detail with reference to the accompanying drawings and examples.

Detailed Description

The terms "upper", "lower", "inner", "outer", "front", "rear", "both ends", "one end", "the other end", and the like in the specification indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, and for example, "connected" may be either fixedly connected or detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Embodiment 1, as shown in fig. 1 to 4, a thrust bearing with reduced weight includes a cage 1, a steel ball group 2 disposed in the cage 1, and a thrust race assembly 3 disposed outside the steel ball group 2, and is characterized in that: retainer 1 is by cyclic annular board component and set up a plurality of steel ball pockets 4 that set up in cyclic annular board component ring circumference, ball pocket 4 in be equipped with the interior clamping face 5 of ball contact, interior clamping face upper and lower extreme respectively be equipped with an oiling groove 6, the inner circle of thrust raceway ring subassembly 3 in set up with the thrust joint recess 7 between the axle. An inner connecting groove 8 is arranged in the inner ring of the retainer 1.

The thrust raceway ring component 3 is formed by precisely rolling an SAE1074 steel strip in a high-speed stamping mode, the processing speed can reach 300 pieces/minute, after quenching and shaping tempering, the product has the roughness of less than Ra0.1, the wall thickness difference of less than 0.01mm and the planeness of less than 0.03mm, and when the bearing rotates, the thrust raceway ring component 3 and the retainer 1 are guided to work through a shaft, so that grinding of the thrust raceway ring is replaced; the stamping process is adopted for production, the thickness of the thrust ring can meet the requirement when being 0.8-1 mm, and the production cost can be reduced by 70%; the retainer adopts PA66 injection moulding, and is high because of moulding the guarantor shaping precision, and the guide is accurate, and the pocket is convenient for the oil storage, and noise at work is low.
