On bearing pad stone, bearing includes the coaming plate that upper base plate and enclosing is located at bearing periphery, and described coaming plate is double-deck coaming plate, its nexine
For nonmetallic coaming plate, its outer layer is stainless steel coaming plate, and the top of stainless steel coaming plate is fixed on upper base plate by attachment screw, no
The base of rust steel coaming plate is bonded with bearing pad stone, makes to surround totally-enclosed space between stainless steel coaming plate, bearing pad stone and upper base plate.
The top of nonmetallic coaming plate described in the utility model is fixed on upper base plate by connecting bolt, nonmetallic coaming plate
Base be bonded with bearing pad stone.
The upper vertical of stainless steel coaming plate described in the utility model is set, and its underpart is bent to the periphery.
Bending angle between the top and bottom of stainless steel coaming plate described in the utility model is 100 ° -170 °.
The top of nonmetallic coaming plate described in the utility model and stainless steel coaming plate fit, and vertically set from top to bottom
Put.
Described stainless steel coaming plate described in the utility model is made up of four independent coaming plate substrates.
The utility model beneficial effect is：A kind of new all-closed spherical bearing, outside dust-proof sealing device is using double-deck
Coaming plate, nexine are made up of polyurethane coaming plate or rubber coaming plate, outer layer of stainless steel coaming plate, stainless steel coaming plate corrosion resistance and ageing-resistant
Excellent performance, avoids polyurethane coaming plate or rubber coaming plate is directly exposed to the open air in sunlight air, reduces by ultraviolet, ozone etc.
The material aging Problem of Failure brought, durability is more preferably.
Stainless steel coaming plate bottom processes flanging, stainless steel coaming plate height is can adjust within the specific limits, to adapt to prop up
Sphere rotates the needs of rear support height change in seat normal operation.Stainless steel coaming plate base is bonded with bearing pad stone, and
And flanging flexural loading so that be in close contact between lower section and bearing pad stone, can effectively prevent dust impurity from entering from rest base
Enter, realize hermetically sealed dust-proof effect.Nonmetallic coaming plate and stainless steel coaming plate are fixed on upper base plate surrounding end face, dismounting side
Just.Therefore, the utility model proposes a kind of new all-closed spherical bearing, have operation principle it is clear, it is simple in construction, installation
The advantages that convenient, excellent corrosion-proof performance, closure are good, service life is long, relative to existing spherical bearing in dust-proof sealing device
On realize upgrading, dust seal significant effect.

Embodiment
The utility model is illustrated with reference to the drawings and specific embodiments, still, the utility model is not limited to this
Embodiment.
A kind of new all-closed spherical bearing, bearing are arranged on bearing pad stone 5, and bearing includes upper base plate 1, the shape of bearing
Formula is a variety of, is set using structure type from top to bottom, and described coaming plate is double-deck coaming plate, and its nexine is nonmetallic coaming plate 3, its
Outer layer is stainless steel coaming plate 4, and material can select polyurethane coaming plate, rubber coaming plate or other materials, and stainless steel plate material can be with
From trades mark such as 0Cr18Ni9,1Cr18Ni9Ti, 316L, stainless steel coaming plate corrosion resistance and ageing-resistant performance are excellent, avoid poly-
Urethane coaming plate or rubber coaming plate are directly exposed to the open air in sunlight air, are reduced the material aging brought by ultraviolet, ozone etc. and are lost
