Abstract
The utility model discloses a motor end cap valve oil seal comprising an air seal cap shell, wherein the end part of the air seal cap shell is provided with an installation seal part with the diameter being larger than that of the air seal cap shell; the installation seal part of the air seal cap shell is internally and fixedly provided with a seal lip; the upper and lower end surfaces of the seal lip are respectively provided with a first washer and a second washer; and the air seal cap shell is also internally provided with a decompression groove which is provided with a through hole communicated with an air conduit. The oil seal has simple structure and convenient processing, is provided with the seal lip which can be firmly fixed no matter how the work environment changes, has good stationarity and sealing performance, and can reduce the negative pressure generated in the motor, thus preventing oil leakage and being capable of effectively prolonging the service life.
Description
Technical field
The utility model relates to a kind of oil sealing, specifically a kind of motor end cover type valve oil seal.
Background technology
At present, the end cover type sliding bearing that motor is used, the motor that generally is used for higher rotation speed, because motor internal is easy to generate negative pressure, so that oil in the bearing and oil gas pass through sealing gland lid easily, suck motor internal, thereby cause electrical fault, existing leakproof oil seal technology, the general oil sealing that adopts, disc, hermetically-sealed constructions such as Oil Guide screw thread, wherein, oil sealing is the structure of using always, but existing oil sealing in use, because with input, the output shaft Long contact time is so unavoidably cause aging, wearing and tearing, thus the phenomenon of leakage of oil caused, need so often to change oil sealing, increase working strength of workers.In addition, because generally being shell and the sealing lip sheet by metal, existing oil sealing combines, generally pass through adhesive bond, or a nylon liner is set on the inwall of metal shell, fix by interference fit between nylon liner and the metal shell inwall, making the sealing lip sheet is that step is fixed in the oil sealing housing, still with the nylon liner, no matter be the fixing mode of bonding or interference fit, its principle is to fix by frictional force, can't guarantee strong bonded like this, and especially operating ambient temperature is higher, and difference variation is bigger, friction is serious, thus fixing not firm, damage easily, not only increase cost, and increased working strength of workers.
Summary of the invention
It is a kind of simple in structure, easy to process that the purpose of this utility model is to provide, and stationarity and good airproof performance can reduce the negative pressure that produces in the motor, thereby prevent leakage of oil, and can effectively improve the motor end cover type valve oil seal in useful life.
In order to reach above purpose, the technical scheme that the utility model adopted is: this motor end cover type valve oil seal, comprise sealing gland lid housing, it is characterized in that: the end of described sealing gland lid housing is provided with the installation sealing of diameter greater than described sealing gland lid diameter of the housing, the installation sealing internal fixation of described sealing gland lid housing is provided with the sealing lip sheet, the upper and lower end face of described sealing lip sheet is respectively equipped with first pad and second pad, also be provided with relief groove in the described sealing gland lid housing, described relief groove is provided with the through hole that is communicated with air conduit.
The utility model is also implemented by following measure: described installation sealing comprises convex shoulder and stop portion, and described convex shoulder and stop portion surround the cavity that is used to place described sealing lip sheet, first pad and second pad.
Described sealing lip sheet, first pad and the coaxial setting of second pad, and with the coaxial setting of described sealing gland lid housing.
The beneficial effects of the utility model are: by on sealing gland lid housing the installation sealing being set, and the sealing lip sheet is set at installation sealing internal fixation, and the sealing lip sheet is arranged between first pad and second pad, the sealing lip sheet is through the clamping of first pad and second pad like this, be fixed on then and install in the sealing, no matter how operational environment changes, the sealing lip sheet all the time can be firm be fixed in the sealing gland lid housing, thereby effectively improved the useful life of oil sealing, and good sealing effect; In addition, by in sealing gland lid housing, relief groove being set, and relief groove is provided with through hole, through hole is connected with air conduit, because air conduit is connected with outside atmosphere, can effectively reduce the negative pressure that produces in the motor swabbing action by relief groove like this to oil in the bearing and oil gas, thereby prevented the leakage of the inner fluid of bearing, effectively improved the sealing of input and output axles, reduced the frequency of oil seal replacement, thereby prolonged the useful life of oil sealing, not only saved cost and maintenance cost, and reduced working strength of workers.
Description of drawings
Fig. 1 is a structure cross-sectional schematic of the present utility model;
Among the figure: 1. sealing gland is covered housing; 2. sealing lip sheet; 3. convex shoulder; 4. stop portion; 5. through hole; 6. first pad; 7. second pad; 8. relief groove; 9. air conduit.
Embodiment
Make the utility model with reference to accompanying drawing 1.This motor end cover type valve oil seal comprises sealing gland lid housing 1 and sealing lip sheet 2, and sealing lip sheet 2 is to be made by polytetrafluoroethylmaterial material, adopts this material, can improve the heat-resisting quantity and the resistance to wear of sealing lip sheet 2, increases the service life.Be provided with the installation sealing of diameter in the end of sealing gland lid housing 1, can prevent effectively that by this structure sealing lip sheet 2 is in use loosening, it is fixed in the sealing gland lid housing 1 greater than the diameter of described sealing gland lid housing 1.
Wherein, above-mentioned installation sealing comprises convex shoulder 3 and stop portion 4, be placed with sealing lip sheet 2, first pad 6 and second pad 7 in the cavity that convex shoulder 3 and stop portion 4 surround, sealing lip sheet 2 can be arranged between first pad 6 and second pad 7 by this structure, like this through the clamping of first pad 6 and second pad 7, can be fixed between convex shoulder 3 and the stop portion 4, so no matter how operational environment changes, sealing lip sheet 2 all the time can be firm be fixed in the sealing gland lid housing 1, thereby effectively improved the useful life of oil sealing, and good sealing effect.
In sealing gland lid housing 1, also be provided with relief groove 8, described relief groove 8 is provided with the through hole 5 that is communicated with air conduit 9, because air conduit 9 is connected with outside atmosphere, can effectively reduce the negative pressure that produces in the motor swabbing action by relief groove 8 like this to oil in the bearing and oil gas, thereby prevented the leakage of the inner fluid of bearing, effectively improved the sealing of input and output axles, reduced the frequency of oil seal replacement, thereby prolonged the useful life of oil sealing, not only save cost and maintenance cost, and reduced working strength of workers.
The utility model is simple in structure, and is easy to process, and no matter how operational environment changes, and the sealing lip sheet all can be fixed firmly, and stationarity and good airproof performance, can reduce the negative pressure that produces in the motor, thereby prevent leakage of oil, can effectively improve the useful life of oil sealing.
