Description
Technical field
The utility model relates to the water rotating seal of a kind of development machine, coal winning machine cutter plate driver main shaft, particularly a kind of combination annulus of water rotating seal of development machine cutter plate driver main shaft.
Background technique
Axial water port is arranged in the drive main spindle of mining excavation machine or coal winning machine cutterhead, axially can feed the higher water of pressure in the water port, the higher water of pressure can be in the ejection of cutterhead place, cutterhead is cooled at work and makes the working surface depositing dust.For the axial water port water flowing in main shaft on frame, the radially water intake that communicates with axial water port is arranged on the drive main spindle, on the frame, the radially water inlet of the axial water port of main shaft is with water swivel, water swivel has the interior circular hole that matches with the excircle of main shaft, the circumference of circular hole has the groove along circumference in the water swivel, radially water port is arranged at the bottom of the groove, groove is to cover on the radially water intake of main shaft, the groove both sides of the interior circular hole of water swivel, lip ring groove along circumference is arranged, the water rotating seal ring is arranged in the lip ring groove, and the water rotating seal ring is used for main shaft at the higher water of rotation sealing load.In the prior art, a kind of compound seal ring of the water rotating seal ring useful being called " Glais ring " in the above-mentioned lip ring groove, " Glais ring " have the interior ring of teflon and the outer shroud of RUBBER O shape ring.Teflon is a rigid material, between the internal diameter of ring and the main shaft external diameter strict matching gap to be arranged in the teflon of this water rotating seal ring, just can make main shaft sealed high pressure water in rotation, though the teflon wear-resisting property is good, friction factor is little, but at development machine, under the more abominable working condition of coal winning machine, using is not that sealing surface can wear and tear behind the long time, behind the sealing surface wear, make the internal diameter and the gap between the main shaft external diameter of ring in the teflon become big, ring can not replenish the gap in the teflon of rigid material, high pressure water is revealed, some water swivel and lubricant oil swivel joint connect together, after revealing, can mix in water water and the performance and the working life that greatly influence lubricant oil after lubricant oil mixes with lubricant oil; Manufacturing has with main shaft that ring is very very difficult in the teflon of strict matching gap, it is higher to manufacture expense, if matching gap is big when manufacturing, short time will reveal, matching gap is little, and ring meeting lock ring is on main shaft in the teflon, and sealing surface changes, cause the friction between the outer shroud of the interior ring of teflon and RUBBER O shape ring, also can cause seal failure very soon; Even internal diameter that encircles in the teflon when manufacturing and main shaft have strict matching gap, also may be different with the thermal expansion coefficient of steel because of teflon, the gap between interior ring of teflon and main shaft is in use changed, the leakage of water takes place; In addition, the both sides of circular hole groove in the water swivel, twice " Glais ring " are arranged respectively, the water rotating seal ring uses under the more abominable working condition of development machine, coal winning machine and often need change in maintenance, pretty troublesome when changing the water rotating seal ring merely in maintenance, this water rotating seal ring is not the sealing that is well suited for as the radially water inlet water swivel of development machine, the axial water port of coal winning machine main shaft.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, propose a kind of manufacture easily, change convenient, the expense of manufacturing is lower, good seal performance, long service life, be suitable as the water rotary sealing assembly of the radially water inlet water swivel sealing of development machine, the axial water port of coal winning machine main shaft.
The utility model is realized with the following method.
It is the combination annulus of rectangle that single-ended water rotary sealing assembly has the cross section of rigid material, the combination annulus has continuous left and right two annulus that internal diameter is identical, have along the mounting groove of " F " shape rubber seal ring of circumference between the inner circumference of combination annulus, the adjacent annulus, " F " shape rubber seal ring is arranged in the mounting groove of " F " shape rubber seal ring, the spring ring in U-shaped cross section is arranged in the opening of " F " shape rubber seal ring, and the inner circumference of right annulus has the rubber seal ring mounting groove along circumference.
The utility model is installed between the inner circumference of the drive main spindle of development machine, coal winning machine cutterhead and the water swivel on the frame, in the both sides, radially water inlet of the inner circumference of water swivel the left and right mounting point of matching with the utility model will be arranged.During installation, in the rubber seal ring mounting groove of right annulus inner circumference, rubber seal ring is installed, in the left and right mounting point of water swivel a utility model is installed respectively, allow " F " shape rubber seal ring one side near the water inlet, after the utility model is installed in the left and right mounting point of water swivel, the opening of " F " shape rubber seal ring is relative, on the sealing limb of " F " shape rubber seal ring seal lip is arranged, then the both sides, radially water inlet of water swivel inner circumference have twice motive sealing pair respectively.
Between the excircle of drive main spindle of inner circumference of the present utility model and rotation at work twice motive sealing pair is arranged, the motive sealing pair has relative left and right " F " shape rubber seal ring, the spring ring that the U-shaped cross section is arranged in the opening of " F " shape rubber seal ring, the opening of " F " shape rubber seal ring is towards the high pressure side, and the spring ring in U-shaped cross section can support the sealing that helps high pressure water to the opening of " F " shape rubber seal ring.
During use, on high-tension side pressure can be the opening spreading of " F " shape rubber seal ring, and " F " shape rubber seal ring has the pressure good more selfsealings performance of high sealing more, and sealing is reliable; When the sealing pair of forming when " F " shape rubber seal ring and drive main spindle had wearing and tearing, the seal lip that the spring ring in U-shaped cross section can promote " F " shape rubber seal ring was affixed to the excircle of drive main spindle, the gap that compensation produces because of wearing and tearing, and working life is longer; The utlity model has left and right " F " shape rubber seal ring and drive main spindle and form initiatively sealing pair, secondary motive sealing pair has the rubber seal ring of left and right annulus inner circumference, and sealing is reliable; The utility model has the combination annulus, in the rubber seal ring mounting groove of inner circumference of combination annulus " F " shape rubber seal ring with selfsealings performance is arranged, can integral replacing, and it is convenient to change when maintenance.
Below in conjunction with accompanying drawing, the utility model is further described.
