Abstract
The utility model discloses the end cap of a kind of three-phase water-pump motor, including end cap body, the middle part of end cap body arranges the rotating shaft connecting hole of multi-ladder pore structure, aperture inside end cap for the rotating shaft connecting hole sequentially increases and forms grease chamber and bearing mounting groove, bearing mounting groove arranges the bearing for positioning rotating shaft, being provided with oil filler point in described end cap body, the import of oil filler point is arranged on end cap bodies top, and the bottom of oil filler point turns on described grease chamber.The utility model design adds grease chamber's topping-up structure on the basis of existing end cover structure, can be that grease chamber adds lubricating oil according to service condition, remain the lubricity of bearing, can effectively extend the service life of bearing, it is ensured that the normal operation of rotating shaft.
Description
Technical field
Basis is practical relates to a kind of water pump three phase electric machine, the end cap of specially a kind of three-phase water-pump motor.
Background technology
At present, general end cap such as Fig. 1 institute of existing water pump three phase electric machine, end cap body 1 ' middle part is provided with one for even
Switching through the connection 11 ' hole of the multi-ladder pore structure of axle 2 ', aperture inside end cap for the connecting hole 11 ' sequentially increases and forms grease chamber
12 ' and bearing mounting groove 13 ', the middle bearing 3 ' arranging for positioning rotating shaft 2 ' of bearing mounting groove 13 '.Here, for ensureing to turn
The normal operation of axle 2 ' and minimizing abrasion, must store a certain amount of lubricating oil to ensure the profit of bearing 3 ' in upper chamber 12 '
Sliding, but in above structure, position, grease chamber 12 ' does not arrange corresponding Refuel structure, and this makes as user is long
Using the high loaded process with motor, the lubricating oil in grease chamber 12 ' will gradually decrease, and its result will seriously reduce bearing 3 '
Lubricity, causes bearing 3 ' abrasion to increase and shorten the life-span, and affects the service behaviour of rotating shaft 2 ' to a certain extent.
Utility model content
For the problems referred to above, the utility model devises the end cap of a kind of three-phase water-pump motor, and it is at existing end cover structure
On the basis of add grease chamber's topping-up structure, can according to service condition be grease chamber add lubricating oil, remain the lubricity of bearing,
Can effectively extend the service life of bearing, it is ensured that the normal operation of rotating shaft.
For achieving the above object, the utility model is by the following technical solutions:
The end cap of a kind of three-phase water-pump motor, including end cap body, the middle part of end cap body arranges multi-ladder pore structure
Rotating shaft connecting hole, aperture inside end cap for the rotating shaft connecting hole sequentially increases and forms grease chamber and bearing mounting groove, bearing pacify
Tankage arranges the bearing for positioning rotating shaft, it is characterised in that: described end cap body is provided with oil filler point, oil filler point
Import is arranged on end cap bodies top, and the bottom of oil filler point turns on described grease chamber.
Further, the import of above-mentioned oil filler point is provided with plug.
The utility model is provided with the topping-up device being made up of oil filler point in end cap, in use, and can be by this oiling
Hole, toward adding lubricating oil in grease chamber, prevents lubricating oil in grease chamber very few and the lubricity that affects bearing, can effectively extend bearing
Service life, it is ensured that the behavior in service of rotating shaft.
Here, when not being lubricated oil adding set, the import of above oil filler point is sealed by plug closure, it is to avoid motor
Use middle because lubricating oil pressure raise and the phenomenon that leaks.
Brief description
Fig. 1, the planar structure schematic diagram of existing three phase electric machine end cap；
Fig. 2, planar structure schematic diagram of the present utility model.
Detailed description of the invention
As in figure 2 it is shown, the end cap of a kind of three-phase water-pump motor, including end cap body 1, the middle part of end cap body 1 is arranged
The rotating shaft connecting hole 11 of multi-ladder pore structure, aperture inside end cap for the rotating shaft connecting hole 11 sequentially increases and forms grease chamber 12 He
Bearing mounting groove 13, arranges the bearing 3 for positioning rotating shaft 2 in bearing mounting groove 13.Described end cap body 1 is provided with note
Oilhole 14, the import of oil filler point 14 is arranged on end cap body 1 top, and the bottom of oil filler point 14 turns on described grease chamber 12.
In actual use, when the lubricating oil in grease chamber 12 reduces, so that it may added in grease chamber by this oil filler point 14
Lubricating oil, prevents lubricating oil in grease chamber 12 very few and the lubricity that affects bearing 3, can effectively extend the service life of bearing 3, protects
The behavior in service of card rotating shaft 2.
Here, affected by the high-speed rotation of rotating shaft 2, the oil pressure in grease chamber 12 can raise at work, to this end, this practicality is new
Type is provided with plug 141 for blocking sealing in the import of oil filler point 14, prevents motor from using, leaking of lubricating oil occurring, keeps away
Exempt from lubricating oil waste and pollute motor housing.
The above, be only better embodiment of the present utility model, not makees the utility model any pro forma
Limit, every to any simple modification made for any of the above embodiments, equivalent variations or repair according to know-why of the present utility model
Decorations, in the range of still falling within technical solutions of the utility model.
