The high-temperature resistant deep groove ball bearing has the advantages of fine stability, long service life and fine sealing effect.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of bearing, particularly a kind of high temperature resistant deep groove ball bearing.
Background technique
Deep groove ball bearing is simple in structure, and working service is convenient.Be mainly used to bear radial load, also can bear certain axial load, when the radial internal clearance of bearing strengthens, have the performance of angular contact ball bearing, can bear bigger axial load.This class bearing frictional resistance is little, and the limit speed height is adapted to run up.
But, the adaptation running temperature-30 of present deep groove ball bearing ℃ between+120 ℃, non-refractory.At high temperature, the ball of present deep groove ball bearing often under the heat expansion effect, can be stuck in Internal and external cycle and can not use or the life-span extremely short, this has obviously hindered the more extensive utilization of deep groove ball bearing.
For this reason, someone begins to research and develop a kind of deep groove ball bearing that can at high temperature work, for example, application number is: 99252851.8, notification number is: the Chinese patent of CN2392027 discloses a kind of High-temperature Deep-furrow Ball Bearing, comprise the outer ring, steel ball, inner ring and Steel Cable Baffle Ring, suit inner ring in the outer ring, inner round wall face along the outer ring respectively has a circle corresponding rolling arc groove mutually with the intermediate portion of the cylindrical wall of inner ring, loading a circle steel ball between two grooves, and on Internal and external cycle one side wall surface, have a ball-loading hole, and the round wall of the inner ring of that side of ball-loading hole or outer ring has draw-in groove, and inlay card has Steel Cable Baffle Ring in the draw-in groove.But this still can not satisfactorily resolve the problem of deep groove ball bearing continuous operation at high temperature.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, the high temperature resistant deep groove ball bearing that proposed a kind of long service life, the energy long-time continuous turns round under high temperature condition.
The purpose of this utility model can realize by following technical proposal: a kind of high temperature resistant deep groove ball bearing, comprise bearing inner race, bearing outer ring and have the ball of retainer, be provided with raceway between described bearing inner race and the bearing outer ring and above-mentioned ball is positioned at this raceway, it is characterized in that, described bearing inner race and both sides, bearing outer ring junction are equipped with annular dust cover and O-ring seal, described seal ring is filled with high temperature-resistant grease in the cavity between described seal ring and the ball between dust cover and ball.
The high temperature-resistant grease of filling in the cavity between seal ring and the ball plays self-lubricating function, can improve the flexibility and the load carrying power of rotation greatly, can not kill at high-temperature condition lower bearing inner ring and bearing outer ring, can also long-time continuous turn round, prolong the working life of bearing.Dust cover and seal ring not only can be in case the dust soiling solution enter into bearing inside, but also can prevent that the grease in the bearing is penetrated into the external world.
In above-mentioned high temperature resistant deep groove ball bearing, described retainer is formed by fixedly connecting by two annular retaining sheets.Two annular retaining sheets forming retainer are fixed together, like this deep groove ball bearing in running, with regard to can not take place because of the operation that two annular retaining sheets come off or problem such as become flexible is brought undesired.
In above-mentioned high temperature resistant deep groove ball bearing, described bearing inner race outer wall all offers annular slot one on the two ends, all offer on the described bearing outer ring inwall two ends and annular slot one corresponding annular slot two, above-mentioned dust cover and seal ring fix between annular slot one and annular slot two.Dust cover and seal ring just can not spin off in bearing like this.
In above-mentioned high temperature resistant deep groove ball bearing, described seal ring adopts the fluorine rubber material to make.
Compared with prior art, the high temperature-resistant grease of filling in the cavity of this high temperature resistant deep groove ball bearing between seal ring and ball plays self-lubricating function, can improve the flexibility and the load carrying power of rotation greatly, can not kill at high-temperature condition lower bearing inner ring and bearing outer ring, can also long-time continuous turn round, prolong the working life of bearing, good stability.Simultaneously dust cover and seal ring not only can be in case the dust soiling solution enter into bearing inside, but also can prevent that the grease in the bearing is penetrated into the external world, good sealing effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1, bearing inner race; 11, annular slot one; 2, bearing outer ring; 21, annular slot two; 3, ball; 4, retention tab; 5, raceway; 6, grease; 7, seal ring; 8, dust cover.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this high temperature resistant deep groove ball bearing comprises bearing inner race 1, bearing outer ring 2 and has the ball 3 of retainer, be provided with raceway 5 and ball 3 and be positioned at this raceway 5 between bearing inner race 1 and bearing outer ring 2, wherein retainer is formed by fixedly connecting by two semi-circular retention tabs 4.Two annular retaining sheets 4 forming retainer are fixed together, like this deep groove ball bearing in running, with regard to can not take place because of the operation that two semi-circular retention tabs 4 come off or problem such as become flexible is brought undesired.Bearing inner race 1, bearing outer ring 2 and ball 3 are all for handling bearing inner race 1, bearing outer ring 2 and the ball of making 3 by Bearing Steel and through high-temperature tempering and stabilization.
