Description
Technical field
The utility model relates to a kind of seal arrangement, is specifically related to a kind of for the output shaft sealing device on rig swivel gear.
Background technique
Under coal mine, in drilling process, the output shaft of rig swivel gear is connected with drilling rod, and drilling rod is hollow, when probing, there is the water of certain pressure to be transported to drilling rod by swivel gear, be transported to drill bit again, wash away drilling cuttings by the hole of drill bit, water also plays the effect into drill bit cooling simultaneously.Swivel gear use a period of time just can be because of the wearing and tearing generation water leakage phenomenon of seal ring at present.
Model utility content
The utility model is to solve the problem that existing rig swivel gear leaks because of the wearing and tearing of seal ring, and then provides a kind of for the output shaft sealing device on rig swivel gear.
Of the present utility modelly a kind ofly comprise housing for the output shaft sealing device on rig swivel gear, spring, bearing cap, nut, back-up ring, two stationary rings, two rotating rings, two bearings, two the first rubber rings, two trim rings and two the second rubber rings, the center hole right-hand member of housing is provided with dome, spring is arranged in housing center hole, two rotating rings are separately positioned on the two ends of spring, the inboard end face of each rotating ring arranges first rubber ring, on each the first rubber ring, be set with a trim ring, outside and the stationary ring of rotating ring join, second rubber ring of radially-outer surface suit of each stationary ring, back-up ring and dome lay respectively at the left and right end in two stationary ring outsides, two bearings are separately positioned on the two ends in back-up ring and dome outside, bearing cap is arranged on the right side of housing, nut is arranged in housing, and be positioned at the bearing outside of left end.
The utlity model has following beneficial effect:
The utility model is arranged on the output shaft of rig swivel gear, by the precession of nut, stationary ring, rotating ring is compressed the surface of contact a of stationary ring and rotating ring by spring force, between rotating ring and output shaft, pass through the first seal with elastometic washer.Between stationary ring and housing, by the second seal with elastometic washer, finally reach the sealing purpose of output shaft and housing water flowing position.

Embodiment
Embodiment one: present embodiment is described in conjunction with Fig. 1, present embodiment comprises housing 1, spring 2, bearing cap 3, nut 4, back-up ring 5, two stationary rings 6, two rotating rings 7, two bearings 9, two the first rubber rings 10, two trim rings 11 and two the second rubber rings 12, the center hole right-hand member of housing 1 is provided with dome 1-1, spring 2 is arranged in housing 1 center hole, two rotating rings 7 are separately positioned on the two ends of spring 2, the inboard end face of each rotating ring 7 arranges first rubber ring 10, on each the first rubber ring 10, be set with a trim ring 11, the outside of rotating ring 7 and stationary ring 6 join, second rubber ring 12 of radially-outer surface suit of each stationary ring 6, back-up ring 5 and dome 1-1 lay respectively at the left and right end in two stationary ring 6 outsides, two bearings 9 are separately positioned on the two ends in back-up ring 5 and dome 1-1 outside, bearing cap 3 is arranged on the right side of housing 1, and bearing cap 3 is connected with housing 1 by connecting element, nut 4 is arranged in housing 1, and be positioned at bearing 9 outsides of left end.Between rotating ring 7 and output shaft 13, seal by the first rubber ring 10.Trim ring 11 makes the first rubber ring 10 fit closely with output shaft 13.Between stationary ring 6 and housing 1, seal by the second rubber ring 12.Rotating ring 7 and stationary ring 6 are under the effect of spring 2 pressure, and a face sealing being in contact with one another at rotating ring 7 and stationary ring 6, finally reaches the sealing purpose of output shaft 13 and housing 1 water flowing position.
When installation, first a stationary ring 6 is installed to the right-hand member of housing 1 from the left end of housing 1, then right-hand member bearing 9 is installed to the right-hand member of output shaft 13, then output shaft 13 is inserted from the right-hand member of housing 1; Pack successively a rotating ring 7, spring, another rotating ring 7, another stationary ring 6 into from the left end of housing 1, then pack back-up ring 5, right-hand member bearing 9 into, nut 4 and output shaft 13 are screwed.
Working principle: when the utility model uses, between stationary ring 6 and housing 1,, by rubber sealing, rotating ring 7 seals by cushion rubber and output shaft 13, rotating ring 7, stationary ring 6 seal at a face by the pressure of spring 2.Finally reach the sealing purpose of output shaft 13 and housing 1 water flowing position.
