Description

Novel thrust ball bearing

Technical Field

The utility model relates to a bearing, more specifically say, it relates to a novel thrust ball bearing.

Background

The thrust ball bearing adopts a design capable of bearing thrust load during high-speed operation and is composed of a washer-shaped ferrule with a raceway groove for rolling balls. Since the ferrule is seat cushion-shaped, the thrust ball bearing is classified into two types, a flat seat cushion type and a self-aligning spherical seat cushion type.

The thrust ball bearing is composed of a seat ring, a shaft ring and a steel ball retainer assembly, the shaft ring is matched with the shaft, and the seat ring is matched with the shell.

Wherein, because thrust ball bearing's seat circle, shaft ring and steel ball retainer subassembly are split type design for there is the clearance between holder and seat circle, the shaft ring, thereby make in thrust ball bearing use, the dust can get into inside and be stained with on the steel ball of holder through these clearances, influences the steel ball and rotates, thereby has reduced thrust ball bearing's life.

Therefore, a new solution is needed to solve this problem.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a dustproof effectual novel thrust ball bearing.

The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides a novel thrust ball bearing, includes seat circle, shaft ring and holder, set up a plurality of pilot holes that are used for assembling the steel ball on the holder, all be provided with dustproof flange along the circumferencial direction on the both ends face of holder, all offer the annular groove that is used for holding dustproof flange in the one side that seat circle and shaft ring are relative, set up a plurality of louvres that are linked together with the pilot hole on the holder periphery wall, be provided with the dust screen circle on the holder periphery wall.

Through adopting above-mentioned technical scheme, through setting up dustproof flange and the annular groove that is used for holding dustproof flange for the dust can be blockked by dustproof flange, thereby in the unable pilot hole that gets into the inside of holder, thereby on the unable steel ball of being stained with attaches, has guaranteed smooth and easy roll of steel ball, has prolonged thrust ball bearing's life.

The utility model discloses further set up to: a gap is formed between the dustproof flange and the annular groove.

By adopting the technical scheme, because a gap is formed between the dustproof flange and the annular groove, the annular groove is not contacted with the dustproof flange, so that no friction exists between the annular groove and the dustproof flange, and the smooth rotation of the shaft seat is ensured.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, a new thrust ball bearing includes a race 1, shaft ring 2 and holder 3 by the GCr15 steel system of making, a plurality of pilot holes 4 that are used for assembling the steel ball have been seted up on the holder 3, all be provided with dustproof flange 5 along the circumferencial direction on the both ends face of holder 3, all offer the annular groove 6 that is used for holding dustproof flange 5 on seat circle 1 and the relative one side of shaft ring 2, be formed with gapped 9 between dustproof flange 5 and the annular groove 6, set up a plurality of louvres 7 that are linked together with pilot hole 4 on the holder 3 periphery wall, the diameter of louvre 7 is dwindled gradually from inside to outside, detachably is connected with dustproof screen ring 8 on the holder 3 periphery wall, dustproof screen ring 8 includes screen panel 10, be provided with a plurality of fixture blocks 11 along the circumferencial direction on the screen panel 10 top internal perisporium, set up a plurality of draw-in grooves 12 that.

At thrust ball bearing during operation, because the both ends of holder 3 are provided with dustproof flange 5, annular groove 6 has all been seted up in the relative one side of seat circle 1 and pedestal ring 2, when assembling thrust ball bearing, dustproof flange 5 can get into in the annular groove 6, make external dust can be blockked by dustproof flange 5, thereby can't get into in the inside pilot hole 4 of holder 3, thereby on can't being stained with and attaching to the steel ball, guaranteed the smooth and easy roll of steel ball, prolonged thrust ball bearing's life.

Because a gap 9 is formed between the dustproof flange 5 and the annular groove 6, the annular groove 6 is not contacted with the dustproof flange 5, so that no friction exists between the annular groove 6 and the dustproof flange 5, and the smooth rotation of the shaft seat is ensured.

Owing to be provided with dustproof wire netting 8 for inside the dust can't get into the pilot hole 4 through louvre 7, both guaranteed the radiating effect of holder 3, also guaranteed that holder 3 is inside can't be infected with the dust, and because dustproof wire netting 8 can be dismantled, make dustproof wire netting 8 dismantle from holder 3 and get off to change the clearance after being infected with more dust, improved dustproof wire netting 8's life.

Because be provided with a plurality of fixture blocks 11 on dust screen circle 8, seted up a plurality of draw-in grooves 12 on retainer 3, go into in draw-in groove 12 through fixture block 11 card for screen panel 10 can be with retainer 3 joint, the joint has the convenient stable characteristics of being connected, makes the stable covering of screen panel 10 ability on louvre 7, and it is more convenient to dismantle.

Because the diameter of louvre 7 is dwindled by inside to outside gradually for the louvre 7 is kept away from the one end of pilot hole 4 and is for the tip end and communicate with the outside, makes in the dust is difficult for getting into louvre 7, and the one end of louvre 7 and pilot hole 4 intercommunication is the stub end, has increased the area of intercommunication with pilot hole 4, makes in the heat conduction that the heat in the pilot hole 4 can be better advances louvre 7, and outwards disperses in louvre 7.

Because the retainer 3 is made of GCr15 steel, GCr15 steel has higher hardness and wear resistance, so that the retainer 3 has higher hardness and is not easy to damage, and meanwhile, the retainer has better wear resistance and is not easy to wear, thereby greatly prolonging the service life of the retainer 3.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
