The structure of the corrosion resistant supporting roller bearing disclosed by the utility model ensures that the bearing has pretty high corrosion resistance and the precision of the raceways of the inner and outer rings and the precision of the inner peripheral surface of the inner ring can meet requirements, so that the service life of the bearing is prolonged in the case of not influencing the bearing reliability.
Description
Technical field
The utility model relates to the supporting rollern bearing.
Background technique
The supporting rollern bearing is because the radial load that bears is big, according to work and material behavior, the manufacturing of many employing Bearing Steels, this material does not have decay resistance, be only applicable to general work operating mode, and to corrosive environments such as the operating mode of specific (special) requirements such as diluted acid, alkalescence, seawater, this class bearing will be difficult to guarantee life-span and reliability requirement, and usability and the life-span of bearing reduce greatly.
The model utility content
The purpose of this utility model be to provide a kind of can be in the corrosivity working environment the corrosion-resistant supporting rollern bearing of reliably working.
The technical solution of the utility model is: a kind of corrosion-resistant supporting rollern bearing, comprise inner ring, outer ring and be arranged at needle roller between the raceway on the inside and outside circle, between the corresponding end at the axial two ends of described inside and outside circle loose rib is installed, the surface of the outer circumferential face of outer ring, end, front and back has chromium coating, the outer surface of described loose rib has chromium coating, and the raceway face of described outer ring and whole inner peripheral surface have the oxidation processes layer.
Described chromium coating one-tenth-value thickness 1/10 is 0.045mm.
Offer the oil hole that radially connects the inner and outer circumferential surfaces of inner ring along bearing on the described inner ring, offer the store oil groove on the inner peripheral surface of outer ring, the oil hole of offering on the notch of store oil groove and the inner ring upwards is oppositely arranged in the footpath of bearing; Described oil hole has more than two and evenly distributes along the circumferential of inner ring in the middle part of inner ring, and described store oil groove is the annular groove around the circumferential distribution of outer ring.
Roller bearing of the present utility model outer ring, the outer surfaces of loose rib has through chrome-plated process handles the chromium coating that forms, and can be according to the actual definite thickness of coating value of engineering, bearing has Corrosion Protection, improved usability and the life-span of bearing in corrosive environment, and bearing outer ring ball track and whole inner ring carry out oxidation processes, because for chromium coating, the thickness of oxidation processes metal surface that layer increases is less, this structure has guaranteed that namely the bearing whole outer surface has stronger corrosion resistance, in having guaranteed again, the precision of outer ring raceway and inner ring inner peripheral surface can meet the demands, thus the life-span of under the situation of the reliability that does not influence bearing substantially, having improved bearing.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
As shown in Figure 1, a kind of embodiment of corrosion-resistant supporting rollern bearing of the present utility model, comprise outer ring 01, inner ring 02 and be arranged at needle roller 04 between the raceway on the inside and outside circle, between the corresponding end at the axial two ends of inside and outside circle loose rib 08 is installed, outer ring 01 external diameter is the ball crown type structure, and SR is the radius of arc of ball crown type structure.The position of the corresponding raceway in the middle part on 01 inner peripheral surface of outer ring offers the store oil groove 012 of 01 annular that circumferentially distributes around the outer ring; On the position of the corresponding raceway in inner ring 02 middle part 4 uniform oil holes 022 are set, oil hole 022 connects the inner and outer circumferential surfaces of inner ring 02, and the oil hole of offering on the notch of store oil groove 012 and the inner ring 022 upwards is oppositely arranged in the footpath of bearing.Corrosion-resistant supporting rollern bearing outer ring 01, inner ring 02, needle roller 04 and loose rib 08 in the present embodiment have adopted the bearing steel material manufacturing, and jump ring 89 has adopted the metallic copper material manufacturing.And for corrosion-resistant, the surface of the outer circumferential face of outer ring 01, end, front and back has chromium coating, the outer surface of described loose rib 08 has chromium coating, and according to the actual definite thickness of coating value 0.045mm of engineering, the raceway face of described outer ring 01 and whole inner ring 02 surface are carried out oxidation processes and are had the oxidation processes layer; Because for chromium coating, the thickness of oxidation processes metal surface that layer increases is less, this structure has guaranteed that namely bearing has stronger corrosion resistance, the precision that has guaranteed inside and outside circle raceway and inner ring inner peripheral surface again can meet the demands, thus the life-span of under the situation of the reliability that does not influence bearing substantially, having improved bearing.
The installed position of the corresponding loose rib 08 in the end of described outer ring 01 is provided with in the outer ring indent step that 01 inner peripheral surface upper edge circumferentially distributes, the indent step has towards the ring surface of the also axial block cooperation of the end face of the loose rib 08 of correspondence and the facade of the 01 circumferential revolution distribution around the outer ring, offer the sealing gasket mounting groove 011 of annular on the described facade, be embedded with seal washer 68 in the described seal washer mounting groove 011, the material of sealing gasket 68 is engineering plastics, and seal washer 68 is connected in by cover shape body 680 and one, and the annular of radially turning up of overlapping shape body one end is outer to turn edge 681,682 formations turn edge in turning over radially, the external diameter of loose rib 08 is less than the internal diameter of the cover shape body 680 of seal washer 68, the outer circumferential face of loose rib 08 is squeezed on cover shape body 680 inner peripheral surfaces and is sealed and matched, the facade of the indent step on cover shape body 680 outer circumferential faces and the outer ring 01 compresses and is sealed and matched, turning edge outward 681 is inlaid in the seal washer mounting groove 011, in turn edge and 682 be attached on the ring surface of described indent step and be located between loose rib 08 and the described ring surface.The installed position of the corresponding loose rib 08 in the end of described inner ring 02 is provided with the ledge structure that circumferentially turns round the indent of distribution in the outer circumferential face upper edge of inner ring 02, this ledge structure has the annular table terrace 020 that cooperates with the end face axial block of corresponding loose rib 08 and around the circumferential conical surface 021 that distributes of revolution of inner ring 02, the small end of the described conical surface 021 bearing axially near step surface 020 and the big end of the conical surface 021 bearing axially on enlarged to the bearing outer end by bearing inside; Namely bearing axially on the conical surface 021 be that the big end of an end is little, the small end of the conical surface 021 than big end bearing axially on more close bearing inside, the big end of the conical surface 021 than small end bearing axially on the outer end of more close bearing.Be set with the jump ring that can radially actuate 89 between the inner peripheral surface that is located in the described conical surface 021 and corresponding loose rib 08 on the described conical surface 021, the cone shape hole wall that jump ring 89 inner peripheral surfaces are and the conical surface 021 coincide and cooperates, jump ring 89 is squeezed on the described conical surface 021 by the inner peripheral surface of loose rib 08 and makes jump ring 89 inner peripheral surface to loose rib 08 under the described conical surface 021 acts on apply radially outer elastic force.
