Description
Technical field
The utility model relates to a kind of swivel joint, particularly a kind of swivel joint for natural lustre finishing machine that can work under the environment of high temperature and high speed.
Background technique
What current swivel joint sealing means majority on the market adopted is end face seal or the ball face sealing of graphite annulus.High-revolving time, the wearing and tearing of graphite annulus are more serious, reduced greatly the working life of swivel joint.Meanwhile, the residue major part that graphite annulus wears away all can be fallen in conduction oil, affects the quality of conduction oil.When operating temperature is higher, the sealing effect of swivel joint on the market neither be fine in addition.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of reasonable in design, the swivel joint for natural lustre finishing machine of long service life.
Technical problem to be solved in the utility model is to realize by following technological scheme, the utility model is a kind of swivel joint for natural lustre finishing machine, comprise the oil outlet tube being connected with iron finishing roller of iron finishing machine, oil outlet tube is set with housing outward, the front end of oil outlet tube is provided with the adpting flange being connected with oil pipe, described adpting flange is bolted on housing, between the rear portion of housing and oil outlet tube, be provided with bearing, the outside of bearing is provided with bearing hold-down ring, bearing hold-down ring is fixed by bolt and housing, be characterized in: the front portion between oil outlet tube and housing is provided with stuffing box packing, at the rear of stuffing box packing, be provided with and be sleeved on oil outlet tube and the backup washer being connected with housing, outside being provided with, be enclosed within the oil-sealing sleeve on oil outlet tube between backup washer and above-mentioned bearing, between oil-sealing sleeve outside and housing, be provided with outside seal, between oil-sealing sleeve inner side and oil outlet tube, be provided with at least one outside framework oil seal, on oil-sealing sleeve, be provided with oil outlet, housing is provided with the leak oil line being connected with oil outlet.
Technical problem to be solved in the utility model can also further realize by following technological scheme, and described bearing is provided with two, between two bearings, is provided with spacer, and spacer is provided with pouring orifice, and housing is provided with the grease nipple being connected with pouring orifice.
Technical problem to be solved in the utility model can also further realize by following technological scheme, and described stuffing box packing is comprised of several Expanded graphite rings, and the length of stuffing box packing is 30-40mm.
Technical problem to be solved in the utility model can also further realize by following technological scheme, and described outside seal is O RunddichtringO.
Technical problem to be solved in the utility model can also further realize by following technological scheme, and the front end of described stuffing box packing and adpting flange connecting part are provided with copper washer, can improve sealing.
Technical problem to be solved in the utility model can also further realize by following technological scheme, and described adpting flange and housing connecting part are provided with sealing gasket.
Compared with prior art, the utility model adopts being used in conjunction with of stuffing box packing and outside framework oil seal, directly seals the leakage oil of oil outlet tube generatrix direction, and stuffing box packing is front, and outside framework oil seal is rear.Stuffing box packing adopts Expanded graphite ring, and the seal length of stuffing box packing has influence on and from stuffing box packing to outside framework oil seal, leaks oily flow and pressure.By increasing the number of graphite annulus, can reduce leakage rate and leak oily pressure.Because the oily pressure after leaking is very little, through outside framework oil seal, sealing effect is better, and has improved working life.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, further describe concrete technological scheme of the present utility model, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
With reference to Fig. 1, a kind of swivel joint for natural lustre finishing machine, comprise the oil outlet tube 8 being connected with iron finishing roller of iron finishing machine, the outer housing 6 that is set with of oil outlet tube 8, the front end of oil outlet tube 8 is provided with the adpting flange 1 being connected with oil pipe, described adpting flange 1 is bolted on housing 6, and described adpting flange 1 is provided with sealing gasket 2 with housing 6 connecting parts.Between the rear portion of housing 6 and oil outlet tube 8, be provided with bearing 10, on oil outlet tube 8, can be provided with the back-up ring that blocks bearing 10, the outside of bearing 10 is provided with bearing hold-down ring, bearing hold-down ring is fixing by bolt and housing 6, and described bearing 10 can be provided with two, is disposed between housing 6 and oil outlet tube 8, between two bearings 10, be provided with spacer 9, spacer 9 is provided with pouring orifice, and housing 6 is provided with the grease nipple 7 being connected with pouring orifice, injects butter lubricated to bearing 10 by grease nipple 7.
Front portion between oil outlet tube 8 and housing 6 is provided with stuffing box packing 13, described stuffing box packing 13 is comprised of several Expanded graphite rings, the length of stuffing box packing 13 is 30-40mm, the front end of stuffing box packing 13 and adpting flange 1 connecting part are provided with copper washer 14, by adpting flange 1, withstand stuffing box packing 13.At the rear of stuffing box packing 13, be provided with and be sleeved on oil outlet tube 8 and the backup washer 3 being connected with housing 6, outside being provided with, be enclosed within the oil-sealing sleeve 12 on oil outlet tube 8 between backup washer 3 and above-mentioned bearing 10, between oil-sealing sleeve 12 outsides and housing 6, be provided with outside seal 4, described outside seal 4 is O RunddichtringO, and O RunddichtringO can play the effect of certain auxiliary seal.Between oil-sealing sleeve 12 inner sides and oil outlet tube 8, be provided with at least one outside framework oil seal 5, on oil-sealing sleeve 12, be provided with oil outlet, housing 6 is provided with the leak oil line 11 being connected with oil outlet.If there is a small amount of oil to leak out from outside framework oil seal 5, oil can be thrown on housing 6 by the oil outlet on oil-sealing sleeve 12, by leak oil line 11, is drawing in oil sump tank.
Due to the self-lubricating property of Expanded graphite ring, can guarantee that oil outlet tube 8 rotates freely in Expanded graphite ring and bearing 10 inner rings.Radial clearance between stuffing box packing 13 and oil outlet tube 8 is an annulus, selects suitable matching gap, and pressure and flow after can making conduction oil by stuffing box packing 13 are very little.Because the pressure of the leakage oil by stuffing box packing 13 is very little, lower than the working pressure of outside framework oil seal 5, make to be reduced to less numerical value by the conduction oil flow of outside framework oil seal 5.The conduction oil that this leakage rate is less can draw in oil sump tank by the oil outlet on oil-sealing sleeve 12 and leak oil line 11, makes that system is more clean, safety.
