Abstract
The utility model relates to a lubricating oil pipe sealing structure which comprises a shaft, a needle bearing and a conical sleeve. The inner race of the needle bearing is sleeved on the shaft, and the outer race of the needle bearing is connected with the conical sleeve; the conical sleeve is provided with a lubricating oil hole communicated with the part between the inner race and the outer race of the needle bearing; the inner race of the needle bearing is longer than the outer race of the needle bearing; the conical sleeve is connected with a conical sleeve cover; the extension parts of both ends of the inner race of the needle bearing are respectively in clearance fit with the conical sleeve and the conical sleeve cover; and the fitting positions among the conical sleeve, the inner race of the needle bearing and the inner race of the needle bearing are both provided with a plurality of annular grooves, and adjacent annular grooves are communicated with each other through axial grooves. The utility model has the technical proposal that the conical sleeve and the conical sleeve cover are in clearance fit with the inner race of the needle bearing, the fitting positions among the conical sleeve, the conical sleeve cover the inner race of the needle bearing are provided with the annular grooves for storing lubricating oil, and the adjacent lubricating grooves are communicated with each other through the axial grooves, so that the lubricant leakage is avoided when a roller spindle rotates and slides, the favorable lubricating seal effect is guaranteed, and the lubricating leakage and bad lubrication are avoided.
Description
Technical field
The utility model belongs to the sealed member field, particularly relates to a kind of oil circuit sealing configuration that is used to realize the sealing of spindle oil road.
Background technique
On the existing drum-type grinding and polishing machine, drum shaft is when rotating, also to axially move, therefore adopt and on drum shaft, be arranged with two needle bearing inner rings, the outer ring of needle bearing is fixed on the taper sheath, and taper sheath is fixed on the frame, and taper sheath is provided with oilhole, logical lubricant oil is to lubricating needle bearing two outer end blow-by in the oilhole between the Internal and external cycle of needle bearing.In use there are problems such as oil impregnate, insufficient lubrication in such structure.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model provides a kind of oil circuit sealing configuration, and taper sheath is provided with distinctive oil circuit sealing at the needle bearing two ends, guarantee oil sealing effect preferably, has avoided oil impregnate and insufficient lubrication.
To achieve the above object, the utility model has adopted following technological scheme:
A kind of oil circuit sealing configuration, comprise axle, needle bearing and taper sheath, the bearing inner race of described needle bearing is set on the axle, the bearing outer ring of described needle bearing connects taper sheath, described taper sheath is provided with the oilhole that is communicated with between the Internal and external cycle with needle bearing, described bearing inner race is longer than bearing outer ring length, described taper sheath is connected with the taper upper shield, the two ends extension of described bearing inner race respectively with taper sheath, taper upper shield Spielpassung, described taper sheath and taper upper shield are equipped with some circular grooves in the cooperation place with bearing inner race, and the adjacent annular groove is communicated with by axial groove.
Be arranged with the bearing inner race of 4 needle bearings on the above-mentioned axle, be provided with spacer ring in the middle of sheathed 2 bearing outer rings on the bearing inner race, two bearings outer ring, spacer ring is provided with annular groove, annular groove bottom is evenly equipped with several radial holes, and described annular groove is communicated with oilhole on being located at taper sheath.
Above-mentioned taper sheath and taper upper shield are equipped with seal ring in the cooperation place with bearing inner race, and seal ring is located at the outside of described circular groove.
The utility model is owing to adopted above technological scheme, taper sheath is set and the taper upper shield is limited in bearing outer ring in the taper sheath, bearing inner race is prolonged setting, make bearing outer ring on bearing inner race, to endwisely slip, with taper sheath and taper upper shield and bearing inner race Spielpassung, and the circular groove of oil storage is set in the cooperation place, adjacent lubrication groove is communicated with by axial groove, avoid drum shaft the oozing out of lubricant oil when rotating and endwisely slipping, guarantee oil sealing effect preferably, avoided oil impregnate and insufficient lubrication.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is made a detailed explanation.
Embodiment 1:
A kind of oil circuit sealing configuration as shown in Figure 1, comprise axle 3, needle bearing, taper sheath 2 and taper upper shield 4, be arranged with the bearing inner race 7 of 4 needle bearings on the above-mentioned axle 3, sheathed 2 bearing outer rings 8 on the bearing inner race 7, taper upper shield 4 is connected on the taper sheath 2 by fastening piece, and two bearings outer ring 8 is limited in the taper sheath 2, can rotating on bearing inner race 7 and endwisely slip in two bearings outer ring 8, is provided with spacer rings 6 in the middle of the above-mentioned two bearings outer ring 8; As shown in Figure 2, above-mentioned spacer ring 6 is provided with annular groove 61, annular groove 61 bottoms are evenly equipped with 8 radial holes 62, and described annular groove is communicated with oilhole 21 on being located at taper sheath 2, and described spacer ring 6 skies are enclosed within on axle or the bearing inner race 7 and have bigger oil storage space; Above-mentioned taper sheath 2 be provided be located at frame 1 on the oilhole 21 that is communicated with of oil hole 11, be communicated with between the Internal and external cycle of oilhole 21 and needle bearing; The two ends extension of above-mentioned bearing inner race 7 respectively with taper sheath 2, taper upper shield 4 Spielpassung, described taper sheath 2 and taper upper shield 4 are equipped with 3 circular grooves 22 in the cooperation place with bearing inner race 7, adjacent annular groove 22 is communicated with by axial groove 41, is provided with seal ring 5 in the outside of above-mentioned circular groove 22.
Lubricant oil is in oil hole 11, oilhole 21 enter the annular groove 61 of spacer ring 6, enter the space of spacer ring 6 and axle or bearing inner race again via radial hole 62, and enter between bearing inner race and the bearing outer ring lubricated, in drum shaft 3 rotations and the process that endwisely slips, lubricant oil infiltrates the gap of bearing inner race 7 and taper sheath 2 and taper upper shield 4, the existence of circular groove 22 can be played the effect of oil storage and similar labyrinth seal, the existence of axial groove 41 can be played the effect of oil return in axial sliding at axle 3 in the process, and seal ring 5 plays the auxiliary seal effect.Thereby this oil circuit sealing configuration can effectively be avoided drum shaft the oozing out of lubricant oil when rotating and endwisely slipping, and has guaranteed oil sealing effect preferably, has avoided oil impregnate and insufficient lubrication.
