Abstract
The utility model discloses the B-mode long loop seals circle of bearing mazy type, it comprises L-type skeleton (55) and is wrapped in the caulking gum (51) outside L-type skeleton, one end of described caulking gum is provided with bending part, it is the lip (53) at 10-20 ° of inclination angle that the other end is provided with caulking gum width direction, caulking gum side between described lip and L-type skeleton is provided with outer groove (52), and opposite side is provided with inner groovy (54).The beneficial effects of the utility model achieve the state lower seal of bearing in running, effectively discharges the pressure of Bearing inner, the pressure in bearing internal external portion is consistent.
Description
Technical field
The utility model relates to seal ring, particularly relates to the B-mode long loop seals circle of bearing mazy type.
Background technique
Bearing is in mechanical transmission course, play parts that are fixing and reduction load friction factor.Alternatively, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor in power transmission process and retainer shaft central position.Bearing is a kind of very important component in contemporary machinery.Its major function is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.By the difference of motor element frictional property, bearing can be divided into rolling bearing and sliding bearing two class.The general operating mode more complicated of electric motor car output shaft bearing, the factor such as season, temperature all can bring very large impact to electric motor car bearing, brings huge test to the sealing of bearing.Existing bearing seal adopts integral seal dustproof design mostly, although this design sealability is superior, the starting torque of bearing not only can be caused large, and integrated type dust-proof seal ring can cause the pressure difference in bearing internal external portion, cause the stuck inefficacy of bearing, working life is short.
Model utility content
The technical problems to be solved in the utility model is that existing electric motor car bearing seal form causes starting torque large, and bearing internal external portion exists pressure difference, and bearing is stuck, reduces bearing working life, provides bearing mazy type B-mode long loop seals circle for this reason.
The technical solution of the utility model is: the B-mode long loop seals circle of bearing mazy type, it comprises L-type skeleton and is wrapped in the caulking gum outside L-type skeleton, one end of described caulking gum is provided with bending part, it is the lip at 10-20 ° of inclination angle that the other end is provided with caulking gum width direction, caulking gum side between described lip and L-type skeleton is provided with outer groove, and opposite side is provided with inner groovy.
Lip described in such scheme and caulking gum width direction are 14 ° of inclination angles.
The beneficial effects of the utility model achieve the state lower seal of bearing in running, effectively discharges the pressure of Bearing inner, the pressure in bearing internal external portion is consistent.

Fig. 2 is the utility model scheme of installation;
In figure, 1, outer ring, 2, inner ring, 3, steel ball, 4, retainer, 5, seal ring, 51, caulking gum, 52, outer groove, 53, lip, 54, inner groovy, 55, L-type skeleton.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the caulking gum 51 that the utility model comprises L-type skeleton 55 and is wrapped in outside L-type skeleton, one end of described caulking gum is provided with bending part, it is the lip 53 at 10-20 ° of inclination angle that the other end is provided with caulking gum width direction, caulking gum side between described lip and L-type skeleton is provided with outer groove 52, and opposite side is provided with inner groovy 54.
As shown in Figure 2, rolling bearing comprises outer ring 1, inner ring 2, steel ball 3, retainer 4 and seal ring 5.When seal ring is installed seal ring 5 to be placed between Internal and external cycle and to be positioned at outside described steel ball, in the dustproof groove that the bending part of seal ring embeds outer ring, realizing reliable sealing, in lip radial direction embeds in collar dustproof groove and the degree embedded is designated as magnitude of interference e.
Seal ring entirety in B-mode structure, when being installed on rolling bearing, just defines B-mode sealed circuit when bearing rotary works, bearing heating expansion, and internal pressure increases gradually and edge along sealed circuit spreads.When pressure spreads along inner groovy 54 to lip 53, because lip 53 exists 10 °, 12 °, 14 °, 16 °, 18 ° or 20 ° of oblique angles, so more larger toward external diffusion pressure, just lip 53 can be backed down, pressure is discharged from Bearing inner, the pressure in bearing internal external portion is consistent, and preferred lip and caulking gum width direction are that at this moment effect is best at 14 ° of inclination angles.
Achieved the self-unloading internal pressure function of bearing by above structure, avoid integral seal and cause bearing internal external portion to there is pressure difference, make bearing locking and early failue.
Claims (2)
1. the B-mode long loop seals circle of bearing mazy type, it is characterized in that it comprises L-type skeleton (55) and is wrapped in the caulking gum (51) outside L-type skeleton, one end of described caulking gum is provided with bending part, it is the lip (53) at 10-20 ° of inclination angle that the other end is provided with caulking gum width direction, caulking gum side between described lip and L-type skeleton is provided with outer groove (52), and opposite side is provided with inner groovy (54).
2. the B-mode long loop seals circle of bearing mazy type as claimed in claim 1, is characterized in that described lip and caulking gum width direction are 14 ° of inclination angles.
