Description
Technical field
The utility model relates to motor bearing lubrication technical field, is specifically related to a kind of motor bearings structure with oil baffle disc.
Background technology
Middle-size and small-size threephase asynchronous bearing is generally grease lubrication, and in bearing, the consumption of lubricating grease should be appropriate, can affect the lubrication of motor bearings very little, the bearing of motor heating that also can cause too much; Although traditional motor bearing lubrication system has oiling and defuelling system, but owing to there is gap between front and back shaft-cup and axle, when motor runs up, lubricating grease can get rid of on motor bearings lid or motor internal stator and rotor winding, not only make bearing of motor oiling cycle time, waste lubricating grease, and motor internal environment can be polluted, cause insulation to decline, affect motor performance.More seriously bearing oil starvation or lubricating grease can be caused to dry up, and directly affect the motor bearings life-span, because bearing fault causes the overheated of motor, or stator rubs mutually with rotor core, causes burn-down of electric motor.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of motor bearings structure with oil baffle disc, and structure is simple, can ensure that bearing lubrication is effective, save lubricating grease, and motor bearings useful life can be ensured, reliability is high.
The motor bearings structure of band oil baffle disc described in the utility model, comprise motor shaft, motor shaft is set with bearing, bearing is equipped with bearing holder (housing, cover), enclosing cover is equipped with in the side of bearing holder (housing, cover), outer oil baffle disc is provided with in the inner chamber that enclosing cover, bearing holder (housing, cover), bearing are formed, outer oil baffle disc motor shaft is that interference fit is installed, outer oil baffle disc fits in bearing inner race, bearing holder (housing, cover) opposite side is equipped with inner cap, be provided with interior oil baffle disc in the inner chamber that inner cap, bearing holder (housing, cover), bearing are formed, interior oil baffle disc and motor shaft are that interference fit is installed, and interior oil baffle disc fits in bearing inner race; Cover outward and be provided with greasing mouth, bearing holder (housing, cover) is provided with oil duct, and greasing mouth is communicated with oil duct.
When motor runs, the inside and outside oil baffle disc of bearing both sides rotates together with motor shaft with bearing inner race, lubricating grease cannot be thrown away in bearing race, the inside and outside oil baffle disc of bearing both sides is firmly enclosed in lubricating grease in bearing, when ensure that high speed operation of motor, bearing lubrication is neither run off oil starvation, also can not consumption too many, completely avoid motor bearings and cause the faults such as motor bearings heating, abnormal sound because of insufficient lubrication or lubricating grease oiling problem, avoid bearing damage, even motor damage.
Sealing ring is provided with between described enclosing cover and motor shaft.
Described bearing is deep groove ball bearing.
The beneficial effect that the utility model is compared with prior art had is:
Motor bearings structure with oil baffle disc is reasonable in design, can ensure that bearing lubrication is effective and can save lubricating grease, avoiding secondary pollution, and this structure can ensure motor bearings useful life effectively, and reliability is high, has very strong economy and practicality.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, motor shaft; 2, inner cap; 3, interior oil baffle disc; 4, sealing ring; 5, enclosing cover; 6, outer oil baffle disc; 7, bearing; 8, greasing mouth; 9, bearing holder (housing, cover); 10, oil duct.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, with the motor bearings structure of oil baffle disc, comprise motor shaft 1, on motor shaft 1, two ends are all set with bearing 7, bearing holder (housing, cover) 9 bearing 7 is equipped with, enclosing cover 5 is equipped with in the side of bearing holder (housing, cover) 9, enclosing cover 5, bearing holder (housing, cover) 9, outer oil baffle disc 6 is provided with in the inner chamber that bearing 7 is formed, outer oil baffle disc 6 and motor shaft 1 are interference fit installation, outer oil baffle disc 6 fits in bearing inner race, bearing holder (housing, cover) 9 opposite side is equipped with inner cap 2, inner cap 2, bearing holder (housing, cover) 9, interior oil baffle disc 3 is provided with in the inner chamber that bearing 7 is formed, interior oil baffle disc 3 and motor shaft 1 are interference fit installation, interior oil baffle disc 3 fits in bearing inner race, enclosing cover 5 is provided with greasing mouth 8, and bearing holder (housing, cover) 9 is provided with oil duct 10, and greasing mouth 8 is communicated with oil duct 10.
Sealing ring 4 is provided with between enclosing cover 5 and motor shaft 1.
Bearing 7 is preferably deep groove ball bearing.
Lubricating grease enters in the inner chamber of inner cap 2 side by greasing mouth 8 and oil duct 10, be assigned in bearing 7 through rolling, when motor runs, in bearing 7 both sides, outer oil baffle disc 3, 6 rotate together with motor shaft 1 with bearing inner race, in bearing 7 both sides, outer oil baffle disc 3, 6 and bearing inner race laminating, lubricating grease is firmly enclosed in bearing, lubricating grease cannot be thrown away in bearing race, when ensure that high speed operation of motor, bearing 7 lubricates the oil starvation that neither runs off, also can not consumption too many, completely avoid motor bearings causes motor bearings to generate heat because of insufficient lubrication or lubricating grease oiling problem, the faults such as abnormal sound, avoid bearing damage, even motor damage.
