End cap ontology is fixed on casing, is easily installed.
The utility model is further arranged to：The mounting ear is set as three and uniform along the circumferencial direction of end cap ontology
Arrangement, the clamping block are set as three, and the end cap ontology offers stress slot between each adjacent clamping block, each
The stress slot is located between adjacent mounting ear.
By using above-mentioned technical proposal, when dismounting end cap ontology overhauls motor, work people can will tear open
The tool of unloading is caught in stress slot, easily facilitates the dismounting of end cap ontology, meanwhile, by the spatial arrangement of mounting ear and stress slot,
Avoid the interference between mounting ear and extracting tool in disassembly process.
In conclusion the utility model has the advantages that：
1. by the setting of mounting ring and sealing ring, compared with outside framework oil seal, easily facilitate between motor and gearbox
Sealing installation, and there is longer service life；
2. by the cooperation of o types sealing ring and arc-shaped annular groove, the damage of sealing ring during the installation process is reduced, is carried
The high service life of sealing ring；
3. bearing is set in mounting ring, bearing is enable to share the lubricating oil in gearbox, improves making for bearing
Use the service life.

Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing.
A kind of electric motor end cap of extended life seal, the electric motor end cap are the drive end bearing bracket of motor 8, as depicted in figs. 1 and 2, packet
Include end cap ontology 1.End cap ontology 1 axially penetrates through the through-hole 2 that 8 shaft 9 of power supply machine passes through, and it is axial that end cap deviates from the side wall in shop
It is connected with mounting ring 3, the internal diameter of the mounting ring 3 is more than the internal diameter of through-hole 2.Wherein, the lateral wall of mounting ring 3 is further opened with
Two annular grooves 4 are both provided with sealing ring 5 in each annular groove 4.It should be noted that annular groove 4 could be provided as it is multiple,
Two be only the present embodiment illustration.
Preferably, sealing ring 5 is o types sealing ring 5, and the rounded setting in section of sealing ring 5, the bottom wall of annular groove 4
It is arranged in arc-shaped, each sealing ring 5 agrees with 4 phase of corresponding annular groove.
It may further be preferable that the slot bottom of annular groove 4 is covered with solid lubricant layer 6, to improve sealing ring 5 in annular groove 4
Interior overturning ability reduces mounting ring 3 during being caught in gearbox to abrasion caused by sealing ring 5, improves close
The service life of seal 5.Wherein, which is made of graphite.
End cap ontology 1 also axially offers recessing groove 7 towards the side of mounting ring 3, and the internal diameter of the recessing groove 7 is more than through-hole
2 internal diameter and the internal diameter for being less than mounting ring 3.10 location and installation of bearing in shaft 9 in mounting ring 3, the outer ring of bearing 10 with
The inner wall of mounting ring 3 is interference fitted, and the side wall of 10 outer ring of bearing is inconsistent to realize to bearing 10 with the side wall of end cap ontology 1
Positioning, while the setting of recessing groove 7 then avoids side wall the interfering with each other between the inner ring of bearing 10 of end cap ontology 1.
By the way that bearing 10 to be installed in mounting ring 3, due to added with a certain amount of gear oil to gear set in gearbox
It is lubricated to improve the transmission performance of gear set, after mounting ring 3 is caught in gearbox, bearing 10 then can be total with gear set
The gear oil enjoyed in gearbox is lubricated, and is avoided staff to the intermittent oiling of bearing 10, is reduced staff's
Workload.Meanwhile 8 quantity of motor is often more in factory, can also there are problems that leakage plus lubricating oil, lead to making for bearing 10
Declined with the service life, and bearing 10 is installed in mounting ring 3 problem that then effectively prevents.
As shown in figure 3, the side wall of end cap ontology 1 is connected with along evenly distributed three of 1 circumferencial direction of end cap ontology
Mounting ear 11, running through between each mounting ear 11 and end cap ontology 1 has mounting hole 12.End cap ontology 1 deviates from the side of mounting ring 3
There are three the clamping block 13 in bending setting, three clamping blocks 13 to be located in the same circular trace for integrally connected.Wherein, the circle
Shape track is with end cap ontology 1 in coaxial arrangement.
End cap ontology 1 offers stress slot 14 between each adjacent clamping block 13, and each stress slot 14 is located at
Between adjacent mounting ear 11.By the setting of stress slot 14, staff can incite somebody to action when dismantling end cap ontology 1 on motor 8
Extracting tool is caught in stress slot 14, the dismounting in order to staff to end cap ontology 1.Meanwhile mounting ear 11 and stress slot
14 spatial arrangement then avoids the interference between mounting ear 11 and extracting tool, improves the operability in disassembly process.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel design concept, any modification, equivalent replacement, improvement and so on should be included in the protection of the utility model
Within the scope of.
