The utility model relates to a kind of permanent magnet synchronous motor bearing seal structure, comprise main shaft, support, end cap, clutch shaft bearing, the second bearing and draining sealing device, main shaft is positioned at support, clutch shaft bearing is arranged between main shaft and support, end cap is arranged on support one side, draining sealing device is installed on support opposite side, the second bearing is arranged between end cap and main shaft, described clutch shaft bearing one side is provided with outside framework oil seal, outside framework oil seal is arranged in draining sealing device, clutch shaft bearing opposite side is provided with bearing trim ring, between bearing trim ring and support, be provided with draining passage, described main shaft, the second bearing, end cap and support surround draining cavity, draining channel connection clutch shaft bearing and draining cavity, the utility model structural design advantages of simple, by by original useless cavity sealing, repack a draining cavity that can store waste oil into, then by the draining passage arranging on support, used waste oil is discharged in draining cavity, can store for a long time waste oil, and draining cavity seals, the possibility that does not also exist waste oil to spill.
Description
Technical field
The utility model relates to a kind of permanent magnet synchronous motor, is specifically related to the bearing seal structure of this permanent magnet synchronous motor.
Background technology
Existing outer rotor permanent magnet motor, is by the effect of bearing, main shaft to be turned round in support, but bearing in the process of running, friction can be increasing, and can produce larger heat, may cause bearing damage, and cause security incident; To the frictional force adding in bearing between rotating part and the inside and outside circle that grease injection can effectively reduce bearing, and can take away in time the heat of generation; But to how to discharge with the waste oil producing later, but become a troubling problem.
1 pair of existing permanent magnet synchronous motor bearing seal structure describes by reference to the accompanying drawings, the outside framework oil seal 1 on what existing permanent magnet synchronous motor bearing seal structure mainly worked be mounted in bearing 2 both sides and 16 and be arranged on the draining sealing device 9 of outside framework oil seal 1 outside, on draining sealing device 9, be provided with draining hole 14, and be provided with screw thread in draining hole 14, by draining screw 15 and the threaded engagement in draining hole 14, draining hole 14 is sealed.But such structure also has this very large weak point.The first point be holed and tapping on draining sealing device 9, and this can increase difficulty of processing and the manufacturing cost of production; Second point, because draining sealing device 9 is provided with draining hole 14, this can reduce the intensity of draining sealing device 9, and can affect the installation of draining sealing device 9.Thirdly, when after grease vaporization, may spill from the edge of draining sealing device 9, pollute.
Summary of the invention
It is a kind of clean that the purpose of this utility model is to provide, and can effectively reduce the permanent magnet synchronous motor bearing seal structure of processing cost and maintenance cost.
The utility model object is to realize like this.
A kind of permanent magnet synchronous motor bearing seal structure, comprise main shaft, support, end cap, clutch shaft bearing, the second bearing and draining sealing device, main shaft is positioned at support, clutch shaft bearing is arranged between main shaft and support, end cap is arranged on support one side, draining sealing device is installed on support opposite side, the second bearing is arranged between end cap and main shaft, clutch shaft bearing one side is provided with outside framework oil seal, outside framework oil seal is arranged in draining sealing device, clutch shaft bearing opposite side is provided with bearing trim ring, between bearing trim ring and support, be provided with draining passage, described main shaft, the second bearing, end cap and support surround draining cavity, draining channel connection clutch shaft bearing and draining cavity, make waste oil can enter draining cavity.
Technique scheme also can be made to the following further improve.
As scheme more specifically, described end cap is bolted on support, is also provided with sealing ring between end cap and support, makes draining cavity in sealing state, does not have oil leakage place.
As scheme more specifically, between draining sealing device and support, use bolt to be fixedly connected with.
As scheme more specifically, described draining passage is to be made up of the gap between bearing trim ring and support.
The utility model structural design advantages of simple, by original useless cavity is sealed, repack a draining cavity that can store waste oil into, then by the draining passage arranging on support, used waste oil is discharged in draining cavity, because the volume of draining cavity is larger, can store for a long time waste oil, and need not often discharge; And draining cavity seals, the possibility that does not also exist waste oil to spill, and need on draining sealing device, not establish draining hole, the intensity of draining sealing device is improved.
Brief description of the drawings
Fig. 1 is existing permanent magnet synchronous motor bearing seal structure schematic diagram.
Fig. 2 is the utility model permanent magnet synchronous motor bearing seal structure schematic diagram.
Fig. 3 is the enlarged diagram of A.
Embodiment
Be described further below in conjunction with the many utility model of drawings and Examples.
In conjunction with Fig. 2 to Fig. 3, embodiment is elaborated: a kind of permanent magnet synchronous motor bearing seal structure, comprise main shaft 7, support 4, end cap 6, clutch shaft bearing 2, the second bearing 8 and draining sealing device 9, main shaft 7 is positioned at support 4, clutch shaft bearing 2 is arranged between main shaft 7 and support 4, end cap 6 is arranged on a side of support 4, end cap 6 is bolted on support 4, between end cap 6 and support 4, be also provided with sealing ring 5, draining sealing device 9 is installed on support 4 opposite sides, the second bearing 8 is arranged between end cap 6 and main shaft 7, described clutch shaft bearing 2 one sides are provided with outside framework oil seal 1, outside framework oil seal 1 is arranged in draining sealing device 9, between draining sealing device 9 and support 4, use bolt to be fixedly connected with, clutch shaft bearing 2 opposite sides are provided with bearing trim ring 3, between bearing trim ring 3 and support 4, be provided with draining passage 11, the essence of draining passage 11 is the gap between support 4 and bearing trim ring 3, main shaft 7, the second bearing 8, end cap 6 and support 4 surround draining cavity 12, draining passage 11 is communicated with clutch shaft bearing 2 and draining cavity 12.
