Abstract
The utility model relates to a pressure control thick-wall bearing, in particular relates to a pressure control thick-wall bearing with a double-barb external buckle type sealing check ring, and belongs to the field of bearings. The pressure control thick-wall bearing comprises an outer ring, an inner ring, and a retainer arranged between the inner ring and the outer ring, wherein a roller is arranged in a containing hole of the retainer and is in contact with the inner ring and the outer ring in a rolling manner; a flat check ring is arranged outside the inner ring; the sealing check ring is arranged between the flat check ring and the outer ring; an oil injection hole is formed in the inner ring; an oil outlet hole is formed in the flat check ring; lubricating oil with oil pressure flows into the bearing through an inner-diameter oil hole of the bearing and flows out through an oil slot in the flat check ring on the end face of the bearing; the outer ring of the bearing is tightly connected with the sealing check ring through buckles, so that the sealing check ring can be prevented from moving along the axial direction of the bearing when bearing the oil pressure; and therefore, the sealing check ring falls off and is loosened from the outer diameter of the bearing after bearing the pressure.
Description
Technical field
The utility model relates to a kind of pressure control heavy wall bearing, specifically relates to a kind of pressure control heavy wall bearing with the outer seizing type Sealing shield ring of two hangnail types, and it belongs to field of bearings.
Background technique
Highi degree of accuracy constant voltage back lining bearing for Si Dierluolin rolling mill, not only to meet the working condition of high-speed overload, also must meet the constant voltage requirement of the inner 0.3MPa-0.4MPa of rolling machine system, thereby stop bearing foreign matter, cutting fluid etc. to enter bearing inside, and ensure the charge oil pressure of mill lubrication system, prevent bearing oil the outflow loss and the pollution that cause, thereby Sealing shield ring is the important component part of bearing, its performance to Sealing shield ring has very high requirement.
Model utility content
In view of the defect that prior art exists, the purpose of this utility model is that a kind of pressure control heavy wall bearing with the outer seizing type Sealing shield ring of two hangnail types will be provided.
For achieving the above object, the technological scheme that the utility model adopts is a kind of pressure control heavy wall bearing with the outer seizing type Sealing shield ring of two hangnail types, it comprises: outer ring, inner ring, be loaded into the retainer between inner ring and outer ring, described retainer pocket is equipped with roller in hole; Roller contacts with the rolling that Internal and external cycle forms, and described inner ring is equipped with loose rib outward, between loose rib and outer ring, Sealing shield ring is housed; Oil hole on inner ring, loose rib is provided with oil outlet, flows into through bearing bore diameter oilhole with the lubricant oil of oil pressure, from bearing face loose rib oil groove, flows out; It is characterized in that: described Sealing shield ring comprises: sealant layer and Steel Skeleton; Described Steel Skeleton external diameter is provided with thick sealant layer, and Steel Skeleton end is provided with boss; It is characterized in that: described rubber seal is provided with two hangnail sealing lips, is respectively the first hangnail sealing lip and the second hangnail sealing lip; Distance between described the first hangnail sealing lip and the second hangnail sealing lip is 1.5mm, and the width of the lip bottom surface of the first hangnail sealing lip is 0.9mm, and the width of the lip bottom surface of the second hangnail sealing lip is 1.2mm.
The sealant layer thickness of described Steel Skeleton external diameter is 0.8mm.
Described Steel Skeleton is seizing type, the high 0.1mm of its boss, wide 1.5mm.
Described sealant layer adopts butyronitrile rubber material.
The magnitude of interference of described sealant layer and outer ring is 0.3mm.
Magnitude of interference between the described pair of hangnail sealing lip and loose rib external diameter is 0.7mm～0.75mm.
Pressure control heavy wall bearing with the outer seizing type Sealing shield ring of two hangnail types as above, its working principle is as follows: Sealing shield ring is arranged on bearing, in the time that bearing internal lubrication oil pressure is no more than 0.3MPa, the first sealing lip and the second sealing lip are all in normal state, in packing state; When bearing internal pressure is during in 0.3MPa～0.4MPa, the first seal lip is turned up, in pressure release state, second lip of seal is in packing state, in the time that bearing internal pressure exceedes 0.4MPa, the first lip and second lip of seal all turn up, in pressure release state.
The utility model has the advantage of:
1, between bearing outer ring and Sealing shield ring, be closely connected by buckle, can prevent that Sealing shield ring from moving axially along bearing in the time bearing oil pressure; Thereby prevent that Sealing shield ring from coming off and becoming flexible from bearing outside diameter after bearing pressure;
2, bearing adopts special oil circuit, lubricant oil with oil pressure flows into through bearing bore diameter oilhole, from bearing face loose rib oil groove, flow out, in meeting bearing lubrication requirement, can stop foreign matter, cutting fluid etc. to enter bearing inside, ensure that bearing turns round in clean environment high speed.
3, bearing internal lubrication oil pressure is controlled, there is the permanent lubrication pressure of 0.3 MPa ~ 0.4MPa, when the lubricating oil pressure providing when oil supply system exceeds standard, the sealing lip of the outer seizing type Sealing shield ring of two hangnail types will turn up, thereby reach the object of pressure release, can avoid because of the bearing internal lubricating system pressure stopping accident causing that exceeds standard;
4, bearing install simple, plain bearing due to seal lip outwardly, in the time installing loose rib, easily cause Sealing shield ring lip to turn up, and be difficult for observing, thereby cause bearing pressure instability in the running, seal ring earlier period damage.And this bearing can first be installed Sealing shield ring, along lip, loose rib is being pushed, install very convenient.
