Description
Technical field
The utility model relates to a kind of bearing, especially a kind of ball bearing with seals.
Background technique
Present bearing, in order to adapt to rugged environment, simultaneously in order to obtain good sealing effect, all needs to take contact seal usually.But contact seal friction torque is large, sealing material loss distortion is fast, reduces working life.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of good sealing effect, the ball bearing with seals of long service life.For addressing these problems, the utility model by the following technical solutions:
A kind of ball bearing with seals, comprise inner ring, outer ring, ball, retainer and seal ring, it is characterized in that: described outer ring is provided with seal groove one, described inner ring is provided with stepped multiple arc seal groove two, the top of described seal ring is arranged in seal groove one, the different sealing lip of multiple height is extended in the bottom of described seal ring, described multiple sealing lips are the corresponding position being arranged on the arc seal groove two of inner ring respectively, wherein be in sealing lip and arc seal groove two interference fit in outside, matching gap between other sealing lips and arc seal groove two, ecto-entad increases successively.
Technical characterstic of the present utility model is also: the top of described seal ring is provided with C shape rebate.
It is the stop wall of 60 ° of angles that described seal groove one is provided with bearing sagittal plane.
The top of described seal ring is provided with the back timber horizontal by-7 ° of angles.
Adopt above technological scheme, the utility model has the following advantages:
1, seal ring of the present utility model is provided with C shape rebate, adds the elastic strain ability of seal ring, facilitates the installation of seal ring.
2, while the outboard seal lip of the utility model seal ring and arc seal groove two interference fit of inner ring, certain gap is kept between other sealing lips and arc seal groove two, like this, when there is wearing and tearing or deformation in outboard seal lip, due to the elasticity of seal ring and the effect of C shape rebate, the sealing lip of inner side can carry out interference fit with corresponding annular seal groove two successively, thus ensures the sealing of bearing, extends the working life of bearing sealed ring.
3, described seal groove one is provided with bearing sagittal plane is the stop wall at 60 ° of angles, compares with the 45° angle of conventional design, and easy to operate, press-in facilitates, does not come off, do not reveal oil.
4, the top of described seal ring is provided with the back timber horizontal by-7 °, when using special Die for pressing cap to be pressed into, and the instantaneous tensioner of back timber, with lasso seal groove one inwall drive fit, meanwhile, instantaneous bending with lasso seal groove one inner wall space, there is special locking effect.
Accompanying drawing explanation
Fig. 1 is generalized section of the present utility model.
Fig. 2 is the enlarged diagram (band seal ring) of the utility model seal groove position.
Fig. 3 is the enlarged diagram (without seal ring) of the utility model seal groove position.
Fig. 4 is the generalized section (first half position is only shown) of the utility model seal ring.
Number in the figure: the sealing lip outside 1 seal groove one, 2 arc seal groove two, 3 seal ring, 31 sealing lips 311,4C shape rebate, 5 stop wall, 6 back timbers, 7 inner rings, 8 outer rings, 9 balls, 10 retainers.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Embodiment 1: as shown in Figure 1, a kind of ball bearing with seals, comprises inner ring 7, outer ring 8, ball 9, retainer 10 and seal ring 3.
As shown in Figure 1, Figure 2 and Figure 4, the top of described seal ring 3 is provided with C shape rebate 4, the top of described seal ring is provided with the back timber 6 horizontal by-7 ° of angles, and the different sealing lip of multiple height 31 is extended in the bottom of described seal ring, and the material of described seal ring generally selects nitrile butadiene rubber.
As shown in Figure 3, described outer ring 8 is provided with seal groove 1, and it is the stop wall 5 at 60 ° of angles that described seal groove 1 is provided with bearing sagittal plane.
Described inner ring is provided with stepped multiple arc seal groove 22.
As shown in Figure 1 and Figure 2, the top of described seal ring is arranged in seal groove 1, described multiple sealing lips 31 are the corresponding position being arranged on the arc seal groove 22 of inner ring respectively, wherein be in sealing lip 311 and arc seal groove two interference fit in outside, have matching gap between other sealing lips and arc seal groove two, and this matching gap ecto-entad increases successively.
During actual assembled, first inner ring 7, outer ring 8 and ball 9 are coordinated, then retainer 10 is installed.That seal ring 3 is installed with that, use special Die for pressing cap by seal ring indentation sealing groove, the instantaneous tensioner of back timber of seal ring, with outer ring seal groove 1 inwall drive fit, meanwhile, the back timber of seal ring is instantaneous to be bent with outer ring seal groove 1 inner wall space, has special locking effect, the deformation and the C shape rebate of seal ring also can bend, produces elastic stress.After bearing uses a period of time, may deformation be there is in the sealing lip 311 outside bearing owing to rubbing, sealing effect can reduce, now, the C shape rebate of seal ring can attempt to reply shape due to the effect of elastic stress, thus be pressed on arc seal groove by the inner seal lip of seal ring, thus ensure sealing effect.
Adopt the technical solution of the utility model, the working life of bearing sealed ring can be extended, and good sealing effect, installation is easier to.
