Abstract
The hermetically sealed single row full-filling roller bearing of a kind of king post system, comprises outer ring, inner ring, main shaft, roller, loose rib and elastic seal ring.Inner ring and loose rib are contained in main shaft one side that is provided with shoulder block successively, and fastening by bolt, the packing ring of spindle nose side, make outer ring, L-type inner ring and loose rib form cavity structure full-complement cylinder roller.Two groups of elastic seal rings of every side are contained in respectively sealing in the set o-ring groove in outer ring and inner ring and loose rib.Described inner ring internal diameter has oil groove, and in the middle part of inner ring raceway width, diametric(al) is provided with two oilholes, and distribution in 90 °, communicates to two oily lines that are provided with main shaft diameter respectively.The utlity model has high-mechanic, sealing is reliable, lubricated simple and easy, is convenient to the installation and removal of bearing, has improved the working life of bearing.
Description
Technical field
The utility model relates to bearing manufacturing technology field, particularly relates to the hermetically sealed single row full-filling roller bearing of a kind of king post system.
Background technique
Along with industrial development, machinery industry also has larger development prospect in every field, and this has just caused the demand of kinds of bearings more diversified.At present, state's inner bearing mostly is open bearing, often can be subject to the erosion of extraneous dust, impurity etc., and sealability is bad, has accelerated the damage of bearing.In addition, in the occasion of High Rotation Speed or high temperature, oil lubrication is more suitable compared with grease lubrication, and conventional oil lubrication mode is for to be lubricated from bearing outside, and so not only fuel consumption is large, and cost is high, and also higher to the quality requirement of lubricant oil.
Model utility content
The technical problems to be solved in the utility model is, provides one to have high-mechanic, and sealing is reliable, the lubricated hermetically sealed single row full-filling roller bearing of easy king post system.
The technological scheme adopting is:
The hermetically sealed single row full-filling roller bearing of a kind of king post system, comprises outer ring, inner ring, main shaft, roller, loose rib, elastic seal ring and packing ring.Described outer ring external diameter flanged pin and rib internal diameter are provided with groove, inner ring is L-type, inner ring and loose rib are contained in main shaft one side that is provided with shoulder block successively, and fastening by bolt, the packing ring of spindle nose side, make to form cavity structure between outer ring, L-type inner ring and loose rib full-complement cylinder roller in the cavity of described formation.The external diameter of described inner ring and loose rib is equipped with o-ring groove, and the outer ring corresponding with inner ring peace retaining ring sealing circle groove is also provided with o-ring groove, and two groups of elastic seal rings of every side are contained in respectively in the set o-ring groove in outer ring and inner ring and loose rib.Described inner ring internal diameter has oil groove, and in the middle part of inner ring raceway width, diametric(al) is provided with two oilholes, and distribution in 90 °, communicates to two oily lines that are provided with main shaft diameter respectively.
The utility model, compared with existing bearing, has following advantages:
1. the utility model is provided with flange in one end, outer ring, has both met main frame bearing portion is installed
Certain space requirement axially and radially, facilitate again the installation of bearing, do not affect host part work simultaneously yet.
2. the utility model outer ring flange internal diameter band is fluted, L-type inner ring rib external diameter be provided with groove same with loose rib external diameter, in the middle of the corresponding upper low groove of outer ring and loose rib, inner ring, sealed by two groups of elastic seal rings of every side, have advantages of effectively prevent bearing internal lubricant leak outside and the harmful matter such as external dust, moisture, foreign matter is invaded bearing inside.
3. the utility model adopts without the design of retainer, and the inner full-complement cylinder roller of bearing effectively raises the bearing capacity of bearing.
4. the utility model main shaft is provided with oily line, inner ring internal diameter has oil groove, and inner ring raceway width middle part diametric(al) is provided with two oilholes, distribution in 90 °, respectively with main shaft diameter to two oily lines communicate, can improve its lubrication effect, add the elastic seal ring of upper bearing (metal) both sides, can effectively carry out oil storage.
5. the utility model has adopted the separable roller bearing structure of NUP type, is convenient to the installation and removal of bearing.
