Compared with prior art, it has the advantages that:
Sealing ring clamping described in the utility model is more secured, and deformation not easily to fall off can be very good to block dust, prevent
Dust enters in bearing, greatly reduces bearing wear damage, improves service life.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is the utility model ring structure schematic diagram.
The utility model is described in further detail below in conjunction with the accompanying drawings.
Specific embodiment
As depicted in figs. 1 and 2, a kind of bearing with special sealing circle, including inner ring 1 and outer ring 2, the inner ring 1 with
Rolling element 3 is equipped between outer ring 2, the rolling element 3 is spherical shape, and the rolling element 3 is cased with retainer 31, and the retainer 31 draws
Guide roll kinetoplast 3 is maintained in bearing, and the retainer 31 is isolated by rolling element 3 with rolling element 3, and the material of retainer 31 has one
Determine intensity, and thermal conductivity is good, friction factor is small, wearability is good, impact flexibility is strong, density is smaller and linear expansion coefficient and rolling element 3
It is close.
Described 1 one end of inner ring extends outwardly, and the extended segment of the inner ring 1 is equipped with top wire hole 11, and the top wire hole 11 is installed
There is a jackscrew 12, in inner ring 1 after installation axle, jackscrew 12 is withstood on axis, can play fixed function;2 outer wall of outer ring is equipped with and leads
Oil groove 21,21 slot bottom of oil guide groove are equipped with oilhole 22, and the oilhole 22 penetrates through 2 inner wall of outer ring, can facilitate addition lubricating oil
Or lubricating grease, bearing is maintained, reduces wear damage, extends bearing service life.
The outside of the rolling element 3 is equipped with sealing ring 4, and the sealing ring 4 includes skeleton 5, sealing lip 6 and rubber bodies 41,
The skeleton 5 is to include top 51, middle part 52 and bottom 53, and the top 51 is hook, and 2 inner wall of outer ring is equipped with fitting groove
23,23 cell wall of fitting groove is equipped with limiting slot 24, and the top 51 is installed in limiting slot 24 so that sealing ring 4 assembles more
Add securely not easily to fall off, while the middle part 52 tilts from inside to outside, and the bottom 53 extends downward close to inner ring 1, in dust
After product overflow on skeleton, it can outward skid off, be not easily accessible in bearing along 52 outer wall of middle part, the rubber bodies 41 are fixed on skeleton
