The present invention can be used alone as bearing setting sleeve, also can use in conjunction with multiple coupling, and axis hole adopts Spielpassung easy for installation, and adopts without key connection, reduces the diameter of axle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is that the present invention dismantles the stifled cross section view of oil.
Embodiment
Below in conjunction with Figure of description, the present invention will be further described:
The present invention includes overcoat 1 and inner sleeve 2, and in order to make overcoat 1 and inner sleeve 2 easily deform under internal oil pressure effect generation magnitude of interference, described overcoat 1 and inner sleeve 2 are set to the different thin-wall circular ring structure of diameter respectively.In order to axially locating bearing inner race, one end of described inner sleeve 2 is provided with flange 10.Described overcoat 1 and inner sleeve 2 are by coordinating location, and described overcoat 1 is sheathed on the outside of inner sleeve 2 by coordinating location, and the two ends of its two ends and inner sleeve 2 are welded into one, form cavity 9 between inner sleeve 2 and overcoat 1.Weld seam between overcoat 1 and inner sleeve 2 is mainly subject to power that cavity 9 internal high pressure produces and the power that produces of bearing radial load, determines the size of weld seam by calculating weld strength.The welding of inner-outer sleeve adopts welding machine special, ensure the high-purity of weld metal, postwelding smooth surface zero defect, and heat affected zone is very little, ensures that workpiece postwelding only has small distortion, and obtains final products by postwelding fine finishing.
Flange 10 inner side surface of described inner sleeve 2 is provided with oilhole 3 and dismounting oilhole 8 are installed, described installation oilhole 3 is communicated with described cavity 9 respectively with dismounting oilhole 8, in the flange 10 of inner sleeve 2, described installation oilhole 3 is connected with on high pressure lubricating cup 4, dismounting oilhole 8 and is connected with dismounting oil stifled 7.Described high pressure lubricating cup 4 is provided with combination seal packing ring 5 with the joint of flange 10 outer side surface, to high pressure lubricating cup 4 screw thread, seal action is played at place, described dismounting oil stifled 7 is provided with O RunddichtringO 6 with the joint of flange 10 outer side surface, can effectively prevent the high pressure grease in cavity 9 from revealing.
Described dismounting oil stifled 7 is made up of plug screw 11, steel ball 12, interior hexagonal short cylindrical end Cock screw 14 and interior hexagonal flush end Cock screw 15, the upper side of described plug screw 11 is provided with oil drainage hole 13, discharges the high pressure grease of cavity 9 inside during for dismantling.
The present invention before the mounting, it is vertically set level, endoporus axes normal is in horizontal plane, first dismounting oil stifled 7 is opened, connect high pressure lubricating cup 4 by high-pressure oil gun and inject high pressure grease in cavity 9, until there is high pressure grease to extrude from dismounting oilhole 8, guarantee to fill it up with grease in advance in cavity 9, by the air emptying in cavity 9, then tighten dismounting oil stifled 7.During installation, first bearing is arranged on precalculated position, relies on bearing outer ring to coordinate location, then the present invention is arranged on the inner ring of bearing, the outer side surface of flange 10 near the inner ring of bearing, now bearing inner race and overcoat of the present invention 1 and be Spielpassung between inner sleeve 2 and axle.High-pressure oil gun connects high pressure lubricating cup 4, is pressed in cavity 9 by high pressure grease by installing oilhole 3, and along with the increase of cavity 9 internal high pressure grease, inner generation high pressure, forces inner-outer sleeve generation radial deformation to produce magnitude of interference and carry out radial support bearing; The inner ring of the flange 10 end face axial positioning bearing in inner sleeve 2.During dismounting, first dismounting oil is blocked up hexagonal flush end Cock screw 15 in 7 to back-out, again hexagonal short cylindrical end Cock screw 14 in inside is slowly unscrewed a few circle, high pressure grease now in cavity 9 holds up steel ball 12, high pressure grease is released by oil drainage hole 13, high pressure in cavity 9 is eliminated, and inner-outer sleeve resiliently deformable is recovered, and makes bearing inner race and overcoat 1 and produces gap between inner sleeve 2 and axle.After removing bearing and the present invention, interior hexagonal short cylindrical end Cock screw 14 and interior hexagonal flush end Cock screw 15 are tightened, prevent dust from oilhole turnover cavity 9.
The present invention is when installing and normally working, and dismounting oil stifled 7 is in locking state, and steel ball 12 is compressed by interior hexagonal short cylindrical end Cock screw 14, and interior hexagonal flush end Cock screw 15 compresses interior hexagonal short cylindrical end Cock screw 14 and plays locking effect.Steel ball 12 and the conical surface are formed and seal, and O type circle 6 pairs of plug screw 11 screw thread places seal, and steel ball 12 and O RunddichtringO 6 prevent the leakage of internal high pressure grease.
