Abstract
The utility model relates to an ultra -thin plane thrust bearing, including bearing inner race, bearing inner race, holder, steel ball, the steel ball setting is in the mounting hole of holder, and the holder is formed by the combination of two and half holders and overlaps the outside of establishing at the steel ball, and half holder includes semi -circular snap ring and the connecting portion adjacent semi -circular snap ring between of a plurality of settings in the mounting hole, and two and half holders are connected through the spring, and the both ends of this spring are connected with the connecting portion of two and half holders respectively. The steel ball of bearing is in normal situation lower time, two and half holders are laminated each other, the mounting hole size that two and half holders are constituteed does not change, when expanding because be heated at the steel ball, the opposite outer expansion of two and half holders of steel ball extrusion, the spring of connecting between two and half holders is tensile gradually, the mounting hole of holder gradually the grow till the size with the steel ball suits, the steel ball can not produce wearing and tearing with the holder at the pivoted in -process, the life that the noise has also prolonged steel ball and holder had both been reduced.
Description
Technical field
The utility model relates to a kind of bearing, especially a kind of super-thin plane thrust-bearing.
Background technique
Thin-wall bearing precision is high, very quiet and bearing capacity is very strong, the bearing capacity of existing super-thin plane thrust-bearing is inadequate on the market, and after bearing uses a period of time, expanding can appear because of being seriously heated in steel ball, present retainer is all the whole installation with fixed size mounting hole, when steel ball volume becomes large, and the size of mounting hole does not change on retainer, cause retainer and steel ball to cause wearing and tearing because of transition friction, have a strong impact on the working life of super-thin plane thrust-bearing.
Model utility content
The purpose of this utility model is the defect in order to solve in prior art existing for super-thin plane thrust-bearing, the super-thin plane thrust-bearing of adjustable mounting hole size when providing a kind of retainer to coordinate with steel ball.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of super-thin plane thrust-bearing, comprise bearing outer ring, bearing inner race, retainer, steel ball, described retainer is arranged between bearing outer ring and bearing inner race, described steel ball is arranged in the mounting hole of retainer, described retainer is combined by two and half retainers and is set in the outside of steel ball, half retainer comprises some joints be arranged between semicircle snap ring in mounting hole and adjacent semicircle snap ring, two and half retainers are connected by spring, and the two ends of this spring are connected with the joint of described two and half retainers respectively.
Above-mentioned a kind of super-thin plane thrust-bearing, the contact wall of described mounting hole and steel ball is coated with wearing layer.
Above-mentioned a kind of super-thin plane thrust-bearing, the joint of described two and half retainers is equipped with corresponding groove, the two ends of described spring are connected with the groove on two and half retainers, spring in the raw time, described two and half retainers are bonded to each other.
Above-mentioned a kind of super-thin plane thrust-bearing, the quantity of described steel ball is 20-25.
The beneficial effects of the utility model are: two and half retainers of this bearing are connected by spring, the two ends of this spring are connected with the joint of two and half retainers respectively, the steel ball of bearing at nominal conditions time, two and half retainers are bonded to each other, the mounting hole size that two and half retainers form does not change, when steel ball expands because of being heated, steel ball extrudes two and half retainers and relatively expands outwardly, the spring connected between two and half retainers stretches gradually, the mounting hole of retainer becomes large gradually until adapt with the size of steel ball, steel ball can not produce with retainer and wear and tear in the process of rotating, both the working life that noise also extends steel ball and retainer had been reduced.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the schematic diagram of the utility model retainer;
Fig. 3 is the A district enlarged view in Fig. 2.
Embodiment
Further understand for making to have structure characteristic of the present utility model and effect of reaching and be familiar with, coordinate detailed description in order to preferred embodiment and accompanying drawing, be described as follows:
As Fig. 1, Fig. 2, shown in Fig. 3, a kind of super-thin plane thrust-bearing, comprise bearing outer ring 1, bearing inner race 2, retainer 3, steel ball 4, retainer 3 is arranged between bearing outer ring 1 and bearing inner race 2, steel ball 4 is arranged in the mounting hole 5 of retainer 3, retainer 3 is combined by two and half retainers and is set in the outside of steel ball 4, half retainer comprises some joints 6 be arranged between semicircle snap ring in mounting hole 5 and adjacent semicircle snap ring, two and half retainers are connected by spring 7, the two ends of this spring 7 are connected with the joint 6 of two and half retainers respectively, the joint 6 of two and half retainers is equipped with corresponding groove 8, the two ends of spring 7 are connected with the groove 8 on two and half retainers, spring 7 in the raw time, two and half retainers are bonded to each other.
Further, mounting hole 5 and the contact wall of steel ball 4 are coated with wearing layer, and the quantity of steel ball 4 is preferably 20-25.
Two and half retainers of this bearing are connected by spring 7, the two ends of this spring 7 are connected with the joint 6 of two and half retainers respectively, the steel ball 4 of bearing at nominal conditions time, two and half retainers are bonded to each other, mounting hole 5 size that two and half retainers form does not change, when steel ball 4 expands because of being heated, steel ball 4 extrudes two and half retainers and relatively expands outwardly, the spring 7 connected between two and half retainers stretches gradually, the mounting hole 5 of retainer 3 becomes large until adapt with the size of steel ball 4 gradually, steel ball 4 can not produce with retainer 3 and wear and tear in the process of rotating, both the working life that noise also extends steel ball 4 and retainer 3 had been reduced.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and specification; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
