Abstract
The utility model relates to a lubricating oil labyrinth seal device for preventing the lubricating oil of an outwards extended shaft of a machine from leaking, and belongs to the technical field of a moving seal device. A sealing ring is arranged on a shaft sleeve which is sheathed on a shaft. A sealing seat is arranged on the shaft sleeve, and is fastened with a basal body. An outer shaft of the shaft sleeve is provided with a special-shaped spring sheet. An oil baffle ring is arranged on the shaft sleeve. A press cover is fastened with the shaft. The structure is simple, compact and reasonable. As a double sealing system composed of the sealing ring and the oil baffle ring is used, good sealing effect is achieved. As the sealing seat is provided with a transverse oil return hole and a longitudinal oil return hole, and the inside of the sealing seat is provided with an oil flowing groove, the lubricating oil is not outwards leaked. The high temperature is resistant, the service life is long, the utility model has no need of frequently changing and the use cost is saved.
Description
Technical field
The utility model relates to a kind of lubricant oil labyrinth gland, is used to prevent the leakage of machine outrigger shaft lubricant oil, belongs to the dynamic seal apparatus technical field.
Background technique
Before the utility model is made, in prior art, be used to prevent the leakage of machine outrigger shaft lubricant oil, normally adopt the gearbox output shaft sealing, and employing be the rubber skeleton seal arrangement.The seal arrangement of this kind structure can not be used for high temperature to be used, and rubber is easily aging, and working life is short, and often replacing, and lubricant oil easily leaks, and sealing effect is poor.
Technology contents
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provides a kind of simple, compact and reasonable for structure; High temperature resistant, long service life, do not need frequent replacing and can guarantee that lubricant oil does not leak, the lubricant oil labyrinth gland of good sealing effect.
Main solution of the present utility model is achieved in that
The utility model mainly adopts seal ring 5 to be contained on the axle sleeve 15, and axle sleeve 15 is enclosed within on the axle 11, and sealing seat 3 is installed on the axle sleeve 15, sealing seat 3 is fastening with matrix 7, on axle sleeve 15 outer shafts 11 deformed spring sheet 6 is housed, flinger ring 12 is installed on the axle sleeve 15, and gland 4 is fastening with axle 11.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Owing to adopted seal ring, flinger ring to form the double seal system, reached extraordinary sealing effect; Be provided with and drop down oil groove owing to be provided with the spill port of both direction anyhow and inboard, can guarantee that lubricant oil does not leak at sealing seat; High temperature resistant, the long service life of energy does not need frequent replacing, has saved user cost greatly.
Description of drawings
Fig. 1 is the utility model structural front view
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly by nut 1, bolt 2,16, sealing seat 3, gland 4, seal ring 5, deformed spring sheet 6, matrix 7, spill port 8, seal ring 9,10, axle 11, flinger ring 12, pad 13, drop down oil groove 14, axle sleeve 15, etc. form.Adopt seal ring 5 to be contained on the axle sleeve 15, seal ring 10 is housed on axle 11, axle sleeve 15 is enclosed within on the axle 11, is provided with saw tooth structure on axle sleeve 15 surfaces and is used for throwing oil, and adopt Spielpassung between the axle 11, guarantees to install simple.Sealing seat 3 is installed on the axle sleeve 15, and sealing seat 3 and matrix 7 are fastening by nut 1, bolt 2, pad 13, and seal ring 9 also is housed on the sealing seat 3.Under sealing seat 3, be provided with the spill port 8 of both direction anyhow and inboard and be provided with and drop down oil groove 14, can guarantee further that lubricant oil does not leak.Abnormity (corrugated) spring sheet 6 is housed on axle sleeve 15 outer shafts 11, when installing, only needs a gland 4 that itself and axle sleeve 15 are together compressed vertically and get final product, needn't adjust with pad at the hot-rolling rear portion.Flinger ring 12 is installed on the axle sleeve 15, and gland 4 is contained in and adopts bolt 16 fastening on the axle 11.
