Abstract
The utility model discloses a motor output shaft does not have lubrication sealing of leakage structure relates to the electromechanical device field, and the left end of this motor output shaft does not have lubrication sealing of leakage structure's motor output end cover is equipped with the seal cover, and the seal cover is equipped with the screw, and seal cover and the mutual screw -thread fit of motor output end cover, and seal cover inside is equipped with a plurality of annular oil storage annulars, and the cross -section of oil storage annular is arc, and feeds through together through a plurality of cylindrical communicating pipe between the adjacent oil storage annular. The seal cover can ensure sufficient leakproofness with the screw -thread fit of motor output end cover, and the cross -section is convex oil storage annular can store sufficient lubricating oil, and communicating pipe can help lubricating oil free flow in the oil storage annular, the lubricated effect of lowering the temperature of improvement.
Description
Technical field
The utility model relates to field of electromechanical equipment, particularly a kind of motor output shaft No leakage lubrication sealing structure.
Background technology
Must hermetically-sealed construction be had between the output shaft of motor and standing motor cover plate, not only can prevent dust from entering motor internal, but also outflow of lubrication oil motor cover plate can be prevented, improve the greasy property of motor.
The hermetically-sealed construction of existing motor output shaft adopts grease baffle or sealing sliding sleeve, however grease baffle or the equal radial location of sealing sliding sleeve loaded down with trivial details, installing/dismounting difficulty, easily rubs with output shaft, generation heat thus burn output shaft.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of motor output shaft No leakage lubrication sealing structure, by arranging some oil storage annular grooves at sealing shroud inwall, and be interconnected by connecting pipe, to store lubricating oil, and be conducive to the circulation of lubricating oil, prevent that output shaft is overheated to be burnt.
For achieving the above object, the utility model provides following technical scheme: a kind of motor output shaft No leakage lubrication sealing structure, it is characterized in that: described motor output shaft No leakage lubrication sealing structure comprises the motor output end lid being arranged on motor output shaft right-hand member, motor output end lid inside is provided with bearing, the right-hand member of motor output end lid is provided with ring cowling, ring cowling is fixedly connected with motor output end lid by some screws, the left end of motor output end lid is provided with sealing shroud, sealing shroud is provided with screw thread, and sealing shroud and the mutual threaded engagement of motor output end lid, sealing shroud inside is provided with the oil storage annular groove of some annulars, the cross section of oil storage annular groove is circular arc, and be connected together by some cylindrical connecting pipes between adjacent oil storage annular groove.
Preferably, described motor output end lid and ring cowling are by carbon structure steel making, and surface is all coated with one deck kirsite.
Preferably, described sealing shroud inwall is provided with the sealant that one deck rubber manufactures.
Preferably, the radius of described oil storage annular groove inner section is not less than 16mm.
The beneficial effect of above technical scheme is adopted to be: the left end of the motor output end lid of this motor output shaft No leakage lubrication sealing structure is provided with sealing shroud, sealing shroud is provided with screw thread, and sealing shroud and the mutual threaded engagement of motor output end lid, sealing shroud inside is provided with the oil storage annular groove of some annulars, the cross section of oil storage annular groove is circular arc, and is connected together by some cylindrical connecting pipes between adjacent oil storage annular groove.The threaded engagement of sealing shroud and motor output end lid can ensure enough sealings, and cross section is that the oil storage annular groove of circular arc can store enough lubricating oil, and connecting pipe can help lubricating oil free flow in oil storage annular groove, improves the effect of lubrication cooling.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is the cutaway view of a kind of motor output shaft No leakage of the utility model lubrication sealing structure.
Wherein, 1-motor output shaft, 2-sealing shroud, 3-motor output end lid, 4-ring cowling, 5-bearing, 6-oil storage annular groove, 7-connecting pipe, 8-screw, 9-screw thread.
Embodiment
The preferred implementation of a kind of motor output shaft No leakage of the utility model lubrication sealing structure is described in detail below in conjunction with accompanying drawing.
Fig. 1 shows the embodiment of a kind of motor output shaft No leakage of the utility model lubrication sealing structure: this motor output shaft No leakage lubrication sealing structure comprises the motor output end lid 3 being arranged on motor output shaft 1 right-hand member, motor output end lid 3 inside is provided with bearing 5, the right-hand member of motor output end lid 3 is provided with ring cowling 4, ring cowling 4 is fixedly connected with motor output end lid 3 by some screws 8, the left end of motor output end lid 3 is provided with sealing shroud 2, sealing shroud 2 is provided with screw thread 9, and sealing shroud 2 and motor output end lid 3 threaded engagement mutually, sealing shroud 2 inside is provided with the oil storage annular groove 6 of some annulars, the cross section of oil storage annular groove 6 is circular arc, and be connected together by some cylindrical connecting pipes 7 between adjacent oil storage annular groove 6.
Motor output end lid 3 and ring cowling 4 are by carbon structure steel making, and surface is all coated with one deck kirsite, corrosion resistance and good, can effectively prevent lubricating oil from corroding.Sealing shroud 2 inwall is provided with the sealant that one deck rubber manufactures, and increases its sealing property.The radius of oil storage annular groove 6 inner section is not less than 16mm, ensures that can store enough lubricating oil in oil storage annular groove 6 lubricates.
With the threaded engagement of motor output end lid 3, sealing shroud 2 can ensure that sealing structure has enough sealings, cross section is that the oil storage annular groove 6 of circular arc can store enough lubricating oil, and connecting pipe 7 can help lubricating oil free flow in oil storage annular groove 6, improve the effect of lubrication cooling.
Above is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
