Description

Thrust bearing

Technical field

The utility model belongs to machinery manufacturing technology field more particularly to a kind of thrust bearing.

Background technique

Bearing is the part of carrying axle, referred to as " mechanical joint ", is indispensable one kind in present mechanical equipment Basic components.The major function of bearing is support rotary shaft or other movable bodies, guides rotational motion or moving movement and bears The load being transmitted to by axis or parts on shaft.

Normal thrust bearing, theoretically upper and lower two bearing surfaces and steel ball friction.But reality is in machinery equipment operation In the process, thereon, fork etc. of the lower axle bearing surface often with contact two sides have friction, lead to bearing surface or contacted with bearing surface The serious wears such as fork, it is often necessary to replace.And major part machinery equipment Replacement procedure is very complicated, replaces time-consuming expense Power often results in loss to vast user friend.

Utility model content

For the defects in the prior art, the utility model provides a kind of thrust bearing, can be limited when receiving thrust, Not with contact surface friction.Reduce mechanical disorder, extends service life.

The thrust bearing of the utility model, including seat ring, blowout patche and ball retainer are equipped on ball retainer multiple Steel ball, seat ring and the opposite side of blowout patche are respectively equipped with the raceway for steel ball rolling, it is characterised in that: the lateral surface of the seat ring Equipped with the blocking position limiting structure for engaging with shift fork, shift fork contacts the lateral surface of seat ring and applies thrust, seat to thrust bearing The lateral surface of circle is the contact surface of itself and shift fork, stops position limiting structure by being arranged in seat ring lateral surface, can be in pushing course In limit is engaged between shift fork, avoid relatively rotating between seat ring and shift fork, eliminate contact friction, reduce it is mechanical therefore Barrier.

Further, the blocking position limiting structure is limit card slot or limited block, the quantity of limit card slot or limited block It is designed as needed with shape.

Further, the blocking position limiting structure is limit card slot, and limit card slot is by the way of removing material in seat ring table Face is process, easy to process, and manufacturing cost is low, does not influence the normal use of thrust bearing.

Further, the width of the limit card slot contacts the width of part not less than shift fork, makes shift fork and thrust The part of bearing touch is stuck in limit card slot, realizes that the engaging between seat ring and shift fork limits.

Further, the outer circle of the seat ring is equipped with annular groove, and the transverse shape of the annular groove is semicircle.

The beneficial effects of the utility model are: the thrust bearing of the utility model, for the contact surface abrasion of thrust bearing And design, the improvement of contact surface is essentially consisted in, the protrusion or recess for not influencing normal use are reserved in contact surface production and processing Position, so that thrust bearing be allowed to be limited when receiving thrust, not with contact surface friction.Reduce mechanical disorder, extending makes Use the service life.

Detailed description of the invention

It, below will be right in order to illustrate more clearly of specific embodiment of the present invention or technical solution in the prior art Specific embodiment or attached drawing needed to be used in the description of the prior art are briefly described.In the accompanying drawings, similar element Or part is generally identified by similar appended drawing reference.In attached drawing, each element or part might not be drawn according to actual ratio.

Fig. 1 is the main view of the utility model；

Fig. 2 is the left view of Fig. 1.

Specific embodiment

It is described in detail below in conjunction with embodiment of the attached drawing to technical solutions of the utility model.Following embodiment is only For clearly illustrating the technical solution of the utility model, therefore it is only used as example, and it is originally practical to cannot be used as a limitation limitation Novel protection scope.

It should be noted that unless otherwise indicated, technical term or scientific term used in this application should be this reality The ordinary meaning understood with novel one of ordinary skill in the art.

The thrust bearing of the present embodiment as shown in Figure 1:, including seat ring 1, blowout patche and ball retainer, on ball retainer Multiple steel balls are installed, the side opposite with blowout patche of seat ring 1 is respectively equipped with the raceway for steel ball rolling, it is characterised in that: described The lateral surface of seat ring 1 is equipped with the blocking position limiting structure for engaging with shift fork, and shift fork contacts the lateral surface of seat ring 1 and to thrust axis Application thrust is held, the lateral surface of seat ring 1 is the contact surface of itself and shift fork, stops limit knot by being arranged in 1 lateral surface of seat ring Structure can engage limit between shift fork, avoid relatively rotating between seat ring 1 and shift fork, eliminate and connect in pushing course Wiping is touched, mechanical breakdown is reduced.

In the present embodiment, the blocking position limiting structure is limit card slot 3 or limited block, limit card slot 3 or limited block Number and shape design as needed.

In the present embodiment, the blocking position limiting structure be limit card slot 3, limit card slot 3 by the way of removing material 1 surface of seat ring is process, and easy to process, manufacturing cost is low, does not influence the normal use of thrust bearing.

In the present embodiment, the width of the limit card slot 3 contacts the width of part not less than shift fork, make shift fork with The part of thrust bearing contacts is stuck in limit card slot 3, realizes that the engaging between seat ring 1 and shift fork limits.

In the present embodiment, the outer circle of the seat ring 1 is equipped with annular groove 2, and the transverse shape of the annular groove 2 is semicircle.

Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new The range of each embodiment technical solution of type, should all cover in the claim of the utility model and the range of specification.
