Abstract
The utility model relates to a leakage proof sealing gland, particularly a packing sealing gland used for rotating shafts. The utility model belongs to the technical field of packing seal, and solves the technical problem that the utility model provides the leakage proof sealing gland to avoid environment pollution and to avoid the trouble of frequent maintenance. The utility model has the technical proposal that the leakage proof sealing gland is provided with a gland body, the center of which is provided with a shaft hole; the inner surface of the shaft hole is provided with a packing sealing groove, and the outer end face of the gland body is additionally provided with an annular oil return chamber, the diameter of which is larger than the diameter of the groove bottom of the packing sealing groove; the bottom part of the oil return chamber is provided with an oil return hole. The utility model can solve the problem of leakage which can not be avoided by the existing sealing gland by using simple structure. The utility model can be used without the problem of the environment pollution caused by leakage, can prolong the use period, can avoid the trouble of frequent maintenance and replacement of sealing wearing parts, and simultaneously has the characteristics of easy processing and convenient operation. The utility model is suitable for use in the sealing gland of the rotating shafts, especially the sealing gland of the rotating shafts on large type driving devices.
Description
Technical field
The utility model relates to the sealing of running shaft, and specifically the packing seal gland of using for a kind of running shaft belongs to the packing seal technical field.
Background technique
In various mechanical facility devices, running shaft normally by the rolling bearing swivel bearing in casings such as speed reducer etc., with the running shaft that motor or actuating device link to each other, its axle head stretches out outside the casing, usually the rotary seal by sealing gland realization external part.Sealing gland can adopt multiple seal form such as the seal with elastometic washer of O shape, lip-type packing sealing, packing seal, mechanical seal, no matter which kind of sealing, the branch that all has only sealability quality, leakage rate size, user cost height, installation and maintenance whether to make things convenient for etc. all can't be accomplished the sealing of zero leakage.In the use; because of multiple reasons such as wearing clearance increases; leakage rate shows a rising trend; not only oil consumption increases, and main is befouling environment, and frequent shutdown is changed seal ring also than trouble in addition; particularly for some the large-scale speed reducers in the smelting industry, gear drive etc.; shut down the maintenance seal arrangement, changing easily damaged parts is a height consuming time, the maintenance operation that labor intensity is big.The oil liquid leakage amount prolongs the seal arrangement life cycle when taking which kind of sealing means to reduce sealing, reduces maintenance load, is the problem that mechanical industry, particularly metallurgy industry institute faces and wish solution jointly.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of inclusion seal gland, to avoid befouling environment and to reduce frequent trouble of overhauling.
The alleged problem of the utility model realizes with following technical solution:
A kind of inclusion seal gland, it has a gland body, there is axis hole at the gland body center, the packing seal groove is arranged on the axis hole internal surface, its improvement is, set up the oil return chamber of annular on the gland body exterior edge face, the diameter of oil return chamber is greater than the groover rot diameter of packing seal groove, and the oil return cavity bottom is provided with spill port.
Above-mentioned inclusion seal gland, the quantity of described packing seal groove are two, and described annular oil return chamber is between two packing seal grooves.
The utility model is warded off the easy structural design in new footpath with other, has solved the leakage problem that sealing gland can't be avoided.Adopt the utility model, do not have and leak the environmental pollution that causes, can prolong the seal arrangement life cycle, reduce the trouble of frequent maintain and replace sealing easily damaged parts; In addition, the utility model also has the characteristics processing, implement of being easy to, and adopts on the rotation axis seal gland in rotation axis seal gland, particularly relatively large transmission device of suiting.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Consult Fig. 1, in the diagram, gland body is the flange plate-like, and the quantity of packing seal groove can be one or more, specifically decides on sealability requirement etc.When the packing seal groove was 1, the oil return chamber can be positioned at the outside of packing seal groove, promptly on the exterior edge face of gland body; When the packing seal groove was two, the oil return chamber can be between two grooves; When a plurality of, can be between two last packing seal grooves.In the illustrated embodiment, the quantity of packing seal groove is two, packing seal groove 4 and outer packing seal groove 5 in being respectively, filling sealed filler in the groove, because the diameter of oil return chamber 3 is greater than the groover rot diameter of packing seal groove, so the minimum point of oil return chamber is lower than the bottom land of packing seal groove, after the lubricant oil that leak at interior packing groove seal groove place enters the oil return chamber, can be recovered in the deceleration box at running shaft place through oil pipe by the spill port 6 of bottom, thereby prevented that fluid is to external leakage.Among the figure, 1 is the lubricant oil oil supply hole, and 2 is the fuel feeding chamber, and 7 is flange, is used for and being located by connecting of casing.
Claims (2)
1. inclusion seal gland, it has a gland body, there is axis hole at the gland body center, the packing seal groove is arranged on the axis hole internal surface, it is characterized in that, set up the oil return chamber of annular on the gland body exterior edge face, the diameter of oil return chamber is greater than the groover rot diameter of packing seal groove, and the oil return cavity bottom is provided with spill port.
2. inclusion seal gland according to claim 1 is characterized in that, the quantity of described packing seal groove is two, and described annular oil return chamber is between two packing seal grooves.
