At present, all adopt double-row conical bearing and pairing single row roller bearing on the crab rope sheave, this two class bearings requirement is installed and the adjustment rules are very complicated and be difficult for grasp, and attached positioning element is various during installation, the complete machine deadweight is increased, be unfavorable for the high lifting requirement of equipment.Therefore, at the shortcoming and defect part that above-mentioned technology exists, research and development are applicable to that the novel low-speed heave-load bearing of using on the crab rope sheave is very necessary.
Summary of the invention
The utility model is intended to the shortcoming and defect part that exists in above-mentioned technology, and provide not only reasonable in design, and compact structure, simple and practical, both be convenient to install, simplified the location component of bearing outer ring and rope sheave again greatly, saved the device space, and had and resistance to wear, anticorrosive, high-mechanic, high rigidity, the reliable and a kind of very easily roller Biserial cylindrical roller bearing of completely adorning of use of stable and safe in operation.
The purpose of this utility model is to adopt following technological scheme to realize: the described roller Biserial cylindrical roller bearing of completely adorning, comprise outer ring, inner ring and cylindrical roller, it is characterized in that: in outer ring with double raceway, two raceway inner rings of packing into and forming by two two rib list raceway inner rings, between the surface of contact of two two rib list raceway inner rings, be provided with oilhole, the several cylinders roller of filling arranged evenly in two raceways of inner ring; In the upper surface of outer ring outer circumferential face and lower surface, be arranged with two grooves parallel, that can hold stop ring, two stop rings of in two grooves, all packing into, the internal diameter of two stop rings is connected in the groove, the external diameter of two stop rings is suspended at respectively outside the outer ring, all installs labyrinth-type excluder in the upper-end surface between outer ring with double raceway and two raceway inner ring uncovered and lower end surface uncovered.
Spacing C1 between described two stop rings is the bearing fitted position, its maximum allowance+0.4mm.
Described each labyrinth-type excluder is made up of seal ring, stopper spring steel wire and the dual-purpose fat of anti-rust and lubrication, the installing seal ring concordant in end face between outer ring with double raceway and two raceway inner ring is uncovered with its end face, the surface of described seal ring imposes phosphatization and handles; Between outer ring and seal ring, be connected with the Spring Steel Wire of stop, fill with the dual-purpose fat of anti-rust and lubrication in the cavity between seal ring bottom surface and cylindrical roller.Compared with prior art, the utility model is not only reasonable in design, and compact structure is simple and practical, and has following advantage:
1, owing on the outer peripheral surface of the outer ring of bearing, be equiped with stop ring, rope sheave directly is assemblied between two stop rings location, has simplified the location component of bearing outer ring and rope sheave greatly, saved the device space.
2, the upper and lower end face of bearing is provided with labyrinth-type excluder, and wherein the phosphatization processing is carried out on the seal ring surface, and inner chamber is filled with the dual-purpose fat of anti-rust and lubrication in advance, makes bearing self possess antifouling antirust function, saves the seal arrangement of rope sheave equipment, has saved the device space; Not only have anti-pollution function, and have the effect that keeps the bearing zoarium, simplified the bearing self structure, be of value to the operational safety that improves bearing and use very convenient.
3, roller is completely adorned no retainer, is arranged in respectively in two inner ring raceways, the gap of strict control roller length direction, help to adjust after this bearing of circumgyration assembling of roller, carry and radially reach axial internal clearance, can simplify greatly to install and adjust rules, ensure the operational safety of bearing.
4, bearing adopts the double-row full-complement roller, has high-mechanic, high rigidity characteristics, and combined cover coil structures simultaneously makes it to bear and radially reaches axial connected load.
5, the rolling element surface reaches very high surface finishment and plain wire shaped through after the special processing, makes bearing have the characteristics of resistance to wearing.
