Description
Technical field
The utility model relates to a kind of motors, specifically set and are related to a kind of sealing structure of motor output shaft.
Background technique
Currently, the leakproofness of motor has an important influence the reliability and service life of motor.Existing design of electrical motor,
As shown in Figure 1, its pass through between drive end bearing bracket and output shaft increase in protect outside framework oil seal realize sealing, and within packet outside framework oil seal
Outer circle contacted with the contact of end cap oil sealing position and interior packet outside framework oil seal oil lip with output shaft surface perimeter direction realize sealing.
But this structure is in actual use, interior guarantor's outside framework oil seal is to be exposed to outer surface of motor, often because of muddy water and sandstone
Impact influence motor leakproofness lead to motor inner inlet or foreign matter, cause motor abnormal sound and burning machine, motor seal performance
Difference.
Utility model content
The purpose of the utility model is to provide a kind of sealing structures of better motor output shaft of motor seal performance.
What the purpose of this utility model was realized in.
A kind of sealing structure of motor output shaft, including drive end bearing bracket, motor output shaft, interior packet outside framework oil seal and axial plane oil
Envelope, the motor output shaft pass through drive end bearing bracket, and axial plane oil sealing and Nei Bao outside framework oil seal are arranged at motor output shaft and drive end bearing bracket
Between, axial plane oil sealing is arranged on the side of drive end bearing bracket outwardly, and interior packet outside framework oil seal is arranged on the side of drive end bearing bracket inwardly, and
There are gaps between axial plane oil sealing and Nei Bao outside framework oil seal.
The above technical solution can be further improved as follows.
Further, the drive end bearing bracket is equipped with the through-hole that power supply machine output shaft passes through, and extending internally on through-hole wall has
Through-hole is separated into leading portion and back segment by annular protrusion, annular protrusion, and the axial plane oil sealing is equipped in leading portion, is equipped in back segment
The interior packet outside framework oil seal, the gap between annular protrusion and motor output shaft constitute the gap.
Further, grease is filled in the gap.
The utility model simple structure and reasonable design, by increasing axial plane oil sealing, the effective muddy water and sandstone of completely cutting off is to electricity
The impact of machine internal seal structure, grease further completely cut off the entrance of muddy water and sandstone, axial plane oil sealing, grease and Nei Bao bone completely
Frame oil sealing triple seal structure substantially increases the operational reliability for improving motor and its service life.
Detailed description of the invention
Fig. 1 is the sealing structure diagrammatic cross-section of conventional motors output shaft.
Fig. 2 is the sealing structure diagrammatic cross-section of the motor output shaft in embodiment.
Fig. 3 is the schematic diagram of the section structure of drive end bearing bracket in embodiment.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments:
Embodiment one, referring to figs. 2 and 3 shown in, a kind of sealing structure of motor output shaft, including motor output shaft 1, preceding
End cap 2, interior packet outside framework oil seal 3 and axial plane oil sealing 4, drive end bearing bracket 2 are equipped with through-hole 20, and extending internally on 20 inner wall of through-hole has annular
Protrusion 6, through-hole 20 is separated into leading portion 21 and back segment 22 by annular protrusion 6, and the axial plane oil sealing 4, back segment are equipped in leading portion 21
The interior packet outside framework oil seal 3 is installed, wherein leading portion 21 refers to one section of the through-hole 20 on drive end bearing bracket 2 outwardly, and back segment 22 refers in 22
Through-hole 20 on drive end bearing bracket 2 inwardly one section.
Motor output shaft 1 passes through the through-hole 20 of drive end bearing bracket 2,1 outer wall of motor output shaft and axial plane oil sealing 4 and Nei Bao skeleton oil
Envelope 3 offsets, and the gap between annular protrusion 6 and motor output shaft 1 constitutes gap 5, is filled with grease in gap 5.
Utility model works process and working principle are as follows:
Interior packet outside framework oil seal 3 is encased in 2 back segment 22 of drive end bearing bracket first, is then assembled drive end bearing bracket 2 and output shaft, most
Axial plane oil sealing 4 is packed on 2 leading portion 21 of drive end bearing bracket afterwards, and fills oil in the gap 5 before outside framework oil seal and axial plane oil sealing 4
Rouge, is finally completed the sealing of output shaft Yu drive end bearing bracket 2, and motor assembly production is convenient, fast.Motor in actual operation, axial plane
Oil sealing 4 rotates together with motor shaft, can effectively prevent part muddy water and sandstone from entering inside motor, axial plane oil sealing 4 with it is interior
Grease between packet outside framework oil seal 3 can completely cut off completely the entrance of muddy water and sandstone, to improve motor reliability and use the longevity
Life.
