Abstract
The utility model relates to a shaft following sealing device, in particular to a movable seal suitable for a shaft. The shaft following sealing device comprises a sealing box (1), a sealing pad base (2), a sealing pad (3), a movable shaft (4), sealing padding (5), a pressing sleeve (6), a gland (7) and the like. The shaft following sealing device has the advantages that due to the fact that the sealing padding is of an elastic particle shape or an elastic strip shape and is mixed through a lubricating agent, under the pressure of the pressing sleeve, the sealing padding moves along with the center of the movable shaft, and leakage, caused by eccentricity of the movable shaft or vibration abrasion, of the padding is avoided; due to the fact that the lubricating agent is contained in the sealing padding, friction resistance of the movable shaft is reduced; after the sealing padding is abraded, new sealing padding only needs to be added, and sealing materials are prevented from being wasted.
Description
Technical field
The utility model relates to a kind of axle servo sealer, is especially applicable to the motive sealing of axle.
Background technique
The shaft sealer using at present, the inner chamber of general sealing case is cylindrical, stuffing box packing is round sheet, due to bias and the vibration of axle, thus the wearing and tearing of stuffing box packing can be caused, thereby produce leakage, and stuffing box packing needs integral replacing, cause the waste of sealing material.
Summary of the invention
The purpose of this utility model is to design a kind of center that can make the servo-actuated tracking axis of stuffing box packing, and stuffing box packing only needs to add, and does not need the axle servo sealer of integral replacing.
The utility model comprises sealing case 1, gasket base 2, sealing gasket 3, moving axis 4, stuffing box packing 5, gland 6 and gland 7 etc.The inside of sealing case 1 is that cylinder is cup-shaped, and there is circular hole in its bottom centre, so that moving axis 4 passes, the outside of sealing case 1 is cylindrical, and there is screw thread its outer end, to be connected with gland 7.Gasket base 2 is frustoconic shape, and there is circular hole at Ta center, so that moving axis 4 passes, has disc-shaped groove on its small end face, to install and fixing seal pad 3.Sealing gasket 3 is tubulose, and there is round flange its one end, to be arranged in gasket base 2, sealing gasket 3 can prevent that stuffing box packing 5 from spilling.Moving axis 4 is cylindrical, can rotate or motion vertically.Stuffing box packing 5 is for having flexible granular or strip, and mix with lubricator, to increase its mobility and lubricated to moving axis 4.Gland 6 is cylindrical, and there is circular hole at Ta center, so that moving axis 4 passes, the interior edge face of gland 6 has frustoconic shape groove, to stuffing box packing 5 is applied axially and radial pressure, there is cylindrical boss the exterior edge face of gland 6, so that gland 6 is from the interior taking-up of sealing case 1.There is circular hole at the center of gland 7, so that moving axis 4 passes, the outside of gland 7 is regular prism shape, so that load and unload and tighten, the inside of gland 7 is that cylinder is cup-shaped, and there is screw thread its inner side, matches with the screw thread of sealing case 1.
This axle servo sealer, first passes sealing case 1 by moving axis 4 in use, and gasket base 2 and sealing gasket 3 are inserted in to moving axis 4, advances the bottom of sealing case 1.Then, stuffing box packing 5 is packed in sealing case 1, gasket base 2 and sealing gasket 3 are installed.Finally, gland 6 and gland 7 are installed, are tightened gland 7, just can use.
The utility model has the advantage of this axle servo sealer, because stuffing box packing is for having flexible granular or strip, and mix with lubricator, so under the pressure of gland, stuffing box packing meeting is with the center of motion tracking moving axis, can not produce leakage because of moving axis bias or vibration abrasion.Because stuffing box packing contains oiling agent, so reduced the surface friction drag of moving axis.After stuffing box packing wearing and tearing, only need to add, avoided the waste of sealing material.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1
The present embodiment as shown in Figure 1, comprises sealing case 1, gasket base 2, sealing gasket 3, moving axis 4, stuffing box packing 5, gland 6 and gland 7 etc.The inside of sealing case 1 is that cylinder is cup-shaped, and there is circular hole in its bottom centre, so that moving axis 4 passes, the outside of sealing case 1 is cylindrical, and there is screw thread its outer end, to be connected with gland 7.Gasket base 2 is frustoconic shape, and there is circular hole at Ta center, so that moving axis 4 passes, has disc-shaped groove on its small end face, to install and fixing seal pad 3.Sealing gasket 3 is tubulose, and there is round flange its one end, to be arranged in gasket base 2, sealing gasket 3 can prevent that stuffing box packing 5 from spilling.Moving axis 4 is cylindrical, can rotate or motion vertically.Stuffing box packing 5 is for having flexible granular or strip, and mix with lubricator, to increase its mobility and lubricated to moving axis 4.Gland 6 is cylindrical, and there is circular hole at Ta center, so that moving axis 4 passes, the interior edge face of gland 6 has frustoconic shape groove, to stuffing box packing 5 is applied axially and radial pressure, there is cylindrical boss the exterior edge face of gland 6, so that gland 6 is from the interior taking-up of sealing case 1.There is circular hole at the center of gland 7, so that moving axis 4 passes, the outside of gland 7 is regular prism shape, so that load and unload and tighten, the inside of gland 7 is that cylinder is cup-shaped, and there is screw thread its inner side, matches with the screw thread of sealing case 1.
