Abstract
The utility model discloses a motor shaft seal structure which comprises a motor cover plate and a motor output shaft; the motor output shaft extends out through the center of the cover plate; the outer side of the cover plate is provided with a seal sliding sleeve; the seal sliding sleeve is made of polyfluortetraethylene, and is sleeved onto the output shaft; one end of the seal sliding sleeve extends into the motor cover plate; the inner wall of the seal sliding sleeve is provided with a throttle groove; and lubricating grease is arranged in the throttle groove. By adopting the technical scheme, the outer side of the cover plate is provided with the seal sliding sleeve; because the seal sliding sleeve is made of polyfluortetraethylene, the service life of the sleeve is long and the sealing effect of the sleeve is good; and the inner wall of the seal sliding sleeve is provided with the throttle groove, and the lubricating grease is arranged in the throttle groove, so that the seal sliding sleeve has a lubricating function, and the output shaft and the seal sliding sleeve do not produce severe friction and heat.
Description
Technical field
The utility model relates to a kind of motor shaft hermetically-sealed construction, belongs to the electromechanics technical field.
Background technology
In order to improve the degree of protection of motor, between the output shaft of motor and the motor cover plate that leaves standstill, hermetically-sealed construction must be arranged.In the prior art, the general seal that adopts three types of the hermetically-sealed construction of motor shaft, first kind of seal adopts rubber throw rijng structure, and be affected by environment easily and lost efficacy, and useful life is short.Second kind of seal is outside framework oil seal, and its shortcoming is that radial location is loaded down with trivial details, the installing/dismounting difficulty, and easy and output shaft rubs, and burns output shaft thereby produce heat.The third seal is the axial plane oil sealing, and the difficult control of its axial location of this seal is the same with second kind of seal, the installing/dismounting difficulty, and easy and output shaft rubs, and burns output shaft thereby produce heat.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of motor shaft hermetically-sealed construction, its long service life and good sealing effect.
The technical solution of the utility model is as follows: a kind of motor shaft hermetically-sealed construction, comprise motor cover plate and motor output shaft, the centre bore that described motor output shaft passes cover plate stretches out, one sealing sliding sleeve is set between the aperture of the middle part of described motor output shaft and motor cover plate one side, described sealing sliding sleeve is made by polytetrafluoroethylene, described sealed sliding cover is sleeved on the output shaft, and the one end stretches in the motor cover plate, the inwall of described sealing sliding sleeve is provided with the throttling groove, in the described throttling groove lubricating grease is housed.
Adopt technique scheme, arranged outside one sealing sliding sleeve at cover plate, because the sealing sliding sleeve adopts polytetrafluoroethylene to make, its long service life, good sealing effect, the inwall of sealing sliding sleeve is provided with the throttling groove, in the throttling groove lubricating grease is housed, makes the sealed sliding cover have lubricating functions, output shaft can not produce serious frictional heat with the sealing sliding sleeve.
In technique scheme, a circle edge is set on the excircle of the other end of described sealing sliding sleeve, described edge is by being bolted on the motor cover plate.
In order to make sealing effectiveness better, be interference fits between described sealing sliding sleeve and the output shaft, and under tighter situation,, also be difficult for producing serious friction between output shaft and the sealing sliding sleeve because polytetrafluoroethylene has self-lubricating function.
Beneficial effect: the utility model is reasonable in design, simple in structure, enforcement is easy, seal is the sealing sliding sleeve that adopts polytetrafluoroethylmaterial material to make, output shaft and the matching design that seals sliding sleeve are become interference fits, fit clearance is very little like this, the throttling groove is arranged in addition, reach good sealing effectiveness, because polytetrafluoroethylene has self-lubricating function, under tighter cooperation, axle can not produce serious frictional heat with sliding sleeve yet.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of the utility model sealing sliding sleeve.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As illustrated in fig. 1 and 2, the utility model is made up of motor cover plate 1, motor output shaft 2 and sealing sliding sleeve 3, the centre bore that described motor output shaft 2 passes cover plate 1 stretches out, one sealing sliding sleeve 3 is set between the aperture of the middle part of described motor output shaft 2 and motor cover plate 1 one sides, described sealing sliding sleeve 3 is made by polytetrafluoroethylene, described sealing sliding sleeve 3 is sleeved on the output shaft 2, and and output shaft 2 between be interference fits; One end of sealing sliding sleeve 3 stretches in the motor cover plate 1, one circle edge 3a is set on the excircle of the other end, described edge 3a is by being bolted on the motor cover plate 1, and the inwall of described sealing sliding sleeve 3 is provided with throttling groove 4, in the described throttling groove 4 lubricating grease is housed.
