Abstract
The oiliness bearing being sleeved on motor output shaft is provided with the utility model discloses a kind of direct current generator output shaft end waterproof construction, including the bearing chamber with opening and the motor output shaft for being arranged in the opening, in the bearing chamber；Also include the bearing end cover and internal bearing cover for being respectively arranged on oiliness bearing axial direction both sides, the bearing end cover is close to oiliness bearing and is fixed on above-mentioned opening, and oil sealing is provided between the internal bearing cover and oiliness bearing；The intersection at the axial both ends of the oiliness bearing and above-mentioned motor output shaft surface is respectively equipped with annular chamfer chamber, and each annular chamfer intracavitary is marked with lubricating oil.A kind of direct current generator output shaft end waterproof construction of the utility model, its is rational in infrastructure, can effectively prevent direct current generator output shaft end from seeping water, so as to improve the service life of direct current generator.
Description
Technical field
It the utility model is related to a kind of direct current generator output shaft end waterproof construction.
Background technology
The easy watered and wetting inside wet environment or the direct current generator of outwork, causes electric motor short circuit to burn；And in electricity
More gap be present between outside inside machine, can not only cause to damage because of water inlet, can also enter motor internal because of dust
And it is bad to cause to radiate, and finally makes burn-down of electric motor；And direct current generator output shaft end is that motor is integrally easiest to position into water,
Therefore it is particularly important to the water-proofing treatment at direct current generator output shaft end.
Utility model content
The purpose of this utility model is to provide a kind of direct current generator output shaft end waterproof construction, and its is rational in infrastructure, can have
Effect prevents direct current generator output shaft end from seeping water, so as to improve the service life of direct current generator.
To achieve the above object, the technical solution of the utility model is a kind of direct current generator output shaft end waterproof knot of design
Structure, including the bearing chamber with opening and the motor output shaft for being arranged in the opening, interior be provided with of the bearing chamber are sleeved on
Oiliness bearing on motor output shaft；Also include being respectively arranged in the bearing end cover and bearing of oiliness bearing axial direction both sides
Lid, the bearing end cover are close to oiliness bearing and are fixed on above-mentioned opening, be provided between the internal bearing cover and oiliness bearing
Oil sealing；The intersection at the axial both ends of the oiliness bearing and above-mentioned motor output shaft surface is respectively equipped with annular chamfer chamber,
Each annular chamfer intracavitary is marked with lubricating oil.In such scheme, the intersection of oiliness bearing and motor output shaft is filled with lubrication
Oil, preferably non-hydrophilic lubricating oil；Due to the presence of lubricating oil, moisture is difficult to by between oiliness bearing and motor output shaft
Gap leak into the inside of direct current generator.By using such scheme, it can effectively prevent direct current generator output shaft end from seeping water, from
And improve the service life of direct current generator.
Preferably, the lateral surface of the bearing end cover is provided with the annular groove on the outside of above-mentioned motor output shaft, should
Waterproof grommet is provided with annular groove, the waterproof grommet is fitted close with the motor output shaft.By using above-mentioned side
Case, strengthen waterproof effect.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and can not limit protection model of the present utility model with this
Enclose.
The utility model specific implementation technical scheme be：
As shown in figure 1, a kind of direct current generator output shaft end waterproof construction, including the bearing chamber 1 with opening and wear
In the motor output shaft 2 of the opening, the bearing chamber 1 is interior to be provided with the oiliness bearing 3 being sleeved on motor output shaft 2；Also wrap
The bearing end cover 4 and internal bearing cover 5 for being respectively arranged on the 3 axial both sides of oiliness bearing are included, the bearing end cover 4 is close to oil-containing axle
Hold 3 and be fixed on above-mentioned opening, oil sealing 6 is provided between the internal bearing cover 5 and oiliness bearing 3；The axle of the oiliness bearing 3
Intersection to both ends and the above-mentioned surface of motor output shaft 2 is respectively equipped with annular chamfer chamber, and each annular chamfer intracavitary is marked with profit
Lubricating oil 7.In such scheme, the intersection of oiliness bearing 3 and motor output shaft 2 is filled with lubricating oil 7, preferably non-hydrophilic
Lubricating oil, due to the presence of lubricating oil 7, moisture is difficult to leak into directly by the gap between oiliness bearing 3 and motor output shaft 2
Flow the inside of motor.By using such scheme, it can effectively prevent direct current generator output shaft end from seeping water, so as to improve direct current generator
Service life.
To further enhance waterproof effect, set on the lateral surface of above-mentioned bearing end cover 4 positioned at the outside of motor output shaft 2
Annular groove, is provided with waterproof grommet 8 in the annular groove, the waterproof grommet 8 is fitted close with motor output shaft 2.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvements and modifications can also be made, these change
Enter and retouch and also should be regarded as the scope of protection of the utility model.
