The sealing device preventing the shaft seal of the mechanical shaft from leaking the oil has the advantages of being scientific and reasonable in technical scheme, simple and practical in structure, convenient to operate, easy to manufacture, low in use cost, capable of thoroughly solving the problem that the oil of the mechanical shaft which adopts thin oil to lubricating is leaked and obvious in use effect.

Description

A kind of seal arrangement that prevents the leakage of oil of mechanical axis shaft seal
Technical field
The utility model relates to a kind of input of machinery, device of output shaft shaft seal leakage of oil administered, and belongs to mechanical shaft seal device technique field.
Background technique
The input of machinery, the leakage of oil of output shaft shaft seal are ubiquitous problems, especially the equipment of thin oil lubricant, the sealing of axle and casing relies on the shaft seal sealing, since input and output shaft when rotation can with the shaft seal friction, long-time running is so that journal wearing, the gap increases, and thin oil can leak along the diameter of axle in the fuel tank.Oil-leakage from mechanical equipment is befouling environment not only, and causes waste and accident potential.Work as journal wearing, only change shaft seal and can not solve Leakage, not only expense height but also maintenance workload are large and change mechanical axis.Therefore how to solve quickly and easily the leakage of oil of machinery shaft seal is maintenance man institute problems of concern always.
The model utility content
Technical problem to be solved in the utility model provides a kind of seal arrangement that prevents the leakage of oil of mechanical axis shaft seal, this seal arrangement is without parts such as dismounting couplers, the grease that can be quickly and easily former shaft seal inefficacy, journal wearing be caused leaks and carries out Efficient software patching, thereby solves the difficult problem of mechanical axis shaft seal leakage of oil.
The technological scheme that solves the problems of the technologies described above is:
A kind of seal arrangement that prevents the leakage of oil of mechanical axis shaft seal, it is comprised of jig, sealing joint strip, jig is the annulus of two body structures of two semicircles up and down, two semicircular ring are connected or are sticked with glue by bolt and connect, the internal diameter of jig annulus and the diameter of axle of mechanical axis are complementary, and there is circumferential groove the inboard of jig annulus along inner circumference, and sealing joint strip embeds in the groove, be evenly equipped with connecting screw hole on the jig circular planes, the connecting screw hole of connecting screw hole and mechanical shaft seal gland is complementary.
The above-mentioned seal arrangement that prevents the leakage of oil of mechanical axis shaft seal, the external diameter of the circumferential groove of described jig annulus inboard is greater than the external diameter of mechanical shaft seal circle.
The above-mentioned seal arrangement that prevents the leakage of oil of mechanical axis shaft seal, the filling screw is arranged at described jig annulus excircle top, fill screw between jig annulus two planes, fill screw along the jig circle diameter, the lower end is connected with the circumferential groove of jig annulus inner circumference, filling screw is 4-6, along jig annulus circumference uniform distribution.
The beneficial effects of the utility model are:
1, do not destroy original sealing, only the failure site of former sealing is done effective compensation.
2, fixture structure is designed to split-type, and is easy for installation, short to the equipment installation time of online use, do not need to shut down for a long time to stop production, and do not need the original coupling of equipment, and the devices such as coupler are removed and can be implemented.
3, in use can fill sealing material at any time, simple to operate, be easy to grasp, do not need special tool and equipment.
4, save the repair and maintenance time, reduce fluid consumption.
The utlity model has that technological scheme is scientific and reasonable, simple structure is practical, easy to operate, be easy to make and characteristics that user cost is low, can thoroughly solve and adopt thin oil lubricant to have machinery input, the output shaft Leakage of sound friction pair, using effect is fairly obvious.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the front view of jig;
Fig. 3 is the A-A sectional view of Fig. 2.
Mark is as follows among the figure: seal case 1, mechanical axis 2, sealing 3, jig 4, sealing joint strip 5, groove 6, connecting screw hole 7, connecting bolt 8, filling screw 9.
Embodiment
The utility model is comprised of jig 4, sealing joint strip 5.
Show among the figure, jig 4 is the annulus of two body structures of two semicircles up and down, the internal diameter of jig 4 annulus and the diameter of axle of mechanical axis 2 are complementary, two semicircular ring are connected or are sticked with glue by bolt and connect, join and process, sealing joint strip 5, easy-to-operat can be changed, be filled up to this design under the prerequisite of not removing the transmission device such as coupling.
Show among the figure that there is circumferential groove 6 inboard of jig 4 annulus along inner circumference, the external diameter of groove 6 is greater than the external diameter of mechanical axis 2 seal rings, can block original sealing behind the sealing joint strip 5 and leaks outside in order to insert in the groove 6, forms effective sealing.Sealing joint strip 5 embeds in the grooves 6.An embodiment of the present utility model adopts the fluorine adhesive tape, the characteristic of, easy-formation high temperature resistant, corrosion-resistant according to fluorine, and fluorine adhesive tape and mechanical axis 2 fit tightly, and form sealing, and easily change.
