Abstract
The utility model relates to a motor end cap, including end cover, set up bearing frame, its characterized in that in the end cover center: the bearing frame includes inner circle and outer lane, is the bearing groove between inner circle and the outer lane, the bearing inslot is filled to have and is soaked the felt that has lubricating oil, lubricating oil has still been annotated to the bearing inslot. The utility model discloses adopt simultaneously that felt flooding system lubrication and filling are lubricated to have a lubrication, moreover in the use of reality lubricated have can not reveal from inside and outside bearing end plate, also need not set up the oil filler point and draining hole manufacturing cost is relatively low.
Description
Technical field
The utility model relates to the parts on a kind of motor, particularly relates to a kind of end cap be arranged on motor.
Background technology
Existing motor, its end cap is except carrying out except sealing function to motor internal, and also need to carry motor bearings, motor bearings is fixed on the bearing pedestal of end cap central.When motor assembles, bearing is loaded the bearing pedestal of end cap central.What the lubrication of bearing adopted is lubricate with the felt being soaked with lubricating oil, and this lubrication deficiencies is: in the process used, the lubrication of felt has and can dry up, and bearing just no longer includes lubrication lubrication, and bearing will be killed, and motor cannot rotate.In order to overcome the defect because felt flooding system lubrication exists, the mode of felt immersion oil is just no longer adopted to lubricate, but directly lubrication is had filling when assembling in end cap, then in fixing, outer bearing cover seals, but because its sealing is incomplete sealing, in use, bearing temperature raises, lubrication has Yin Wendu rising and viscosity diminishes, lubricating oil can run off from the gap between interior outer bearing cover and end-cover axle bearing, easily cause bearing lubrication not enough and damage bearing, in order to overcome this defect, just need not timing take apart interior outer bearing cover to end cap inject lubricating oil, very inconvenient.
Authorization Notice No. is CN201515275U, authorized announcement date is that the Chinese utility model patent on June 23rd, 2010 discloses a kind of electric motor end cap noting lubricating oil, as shown in Figure 1, comprise end cover body 1, the center of described end cover body 1 is provided with bearing pedestal 2, described end cover body 1 is also provided with oil filler point 4, and described bearing pedestal 2 is through by oil filler point 4 and end cap outer peripheral face.Described end cover body 1 is also provided with oil leak hole 5, and described bearing pedestal 2 is through by oil leak hole 5 and end cap outer peripheral face.Described oil filler point 4 and oil leak hole 5 are positioned at end cap outer peripheral face one end and are provided with oilhole lid.Have employed the electric motor end cap noting lubricating oil of the present utility model, when not dismantling bearing end cover or internal bearing cover, oil filling can be carried out to motor bearings 3 by oil filler point, by oil leak hole, the lubricating oil in bearing pedestal can also be discharged, the lubricating oil in bearing pedestal is changed in timing, simple and convenient.
But this utility model also has the following disadvantages:
The oil filler point arranged and oil leak hole reduce the rigidity of end cap, in use, end cap may be out of shape, and causes oil filler point and inclined oil hole of air distortion cannot complete oiling and draining action normally, the setting of oil filler point and oil leak hole too increases the manufacture difficulty of end cover die, improves manufacturing cost.When reality uses, the lubricating oil in end cap is subject to the effect of centrifugal force, and lubrication has can enter into oil filler point and oil leak hole, decreases the amount with the lubricating oil of bearing touch in end cap, affects lubricant effect.
Utility model content
In order to overcome the defect that above-mentioned prior art exists, the utility model provides a kind of electric motor end cap, this electric motor end cap adopts felt flooding system lubrication and filling lubrication to have lubrication simultaneously, and lubrication has and can not reveal from inside and outside bearing (ball) cover in the use procedure of reality, also oil filler point need not be set and oil leak hole manufacturing cost is relatively low.
The utility model for solving the problems of the technologies described above adopted technical scheme is:
A kind of electric motor end cap, comprises end cover body, arranges bearing pedestal in end cover body center, it is characterized in that: described bearing pedestal comprises inner ring and outer ring, be bearing groove between inner ring and outer ring, in described bearing groove, be filled with the felt being soaked with lubricating oil, in described bearing groove, be also marked with lubricating oil.
In described bearing groove, lubricating oil steel ring is also installed, in lubricating oil steel ring, fills lubricating oil, lubricating oil steel ring is provided with oil outlet.
Also be provided with cooler in described bearing groove, cooler is the cooling water pipe of coil pipe dress, and cooling water pipe enters to be attached on the madial wall of described outer ring, and cooler one end is water inlet, and the other end is delivery port.
Compared with prior art, the utility model has following beneficial effect:
The utility model comprises end cover body, arranging bearing pedestal in end cover body center, it is characterized in that: described bearing pedestal comprises inner ring and outer ring, is bearing groove between inner ring and outer ring, be filled with the felt being soaked with lubricating oil in described bearing groove, in described bearing groove, be also marked with lubricating oil.The utility model had both been placed felt and had been marked with lubricating oil in bearing groove, due to the existence of the lubricating oil in bearing groove, the lubrication of felt has and would not dry up, also just avoid because felt lubricating oil dries up the defect brought, and due to the existence of felt, although lubricating oil viscosity when being heated reduces, also can not reveal in interior outer bearing cover, both interact, and have both extended the service time of bearing (ball) cover, and it also avoid the leakage of lubricating oil.Owing to not adopting oil filler point and oil leak hole, also would not occur that end cap is out of shape, manufacturing cost improves and affect the defect of lubricant effect.
In the utility model bearing groove, lubricating oil steel ring is also installed, in lubricating oil steel ring, fills lubricating oil, lubricating oil steel ring is provided with oil outlet.By the effect of lubricating oil steel ring, in the use procedure of reality, due under the effect of centrifugal force, lubricating oil is thrown out of, and enters in bearing groove and lubricates bearing, throws away lubricating oil at any time like this in the process used, avoid drying up the defect brought due to lubricating oil, by such setting, also significantly reduce the more frequency of oil change, reduced the use cost of motor.
Also be provided with cooler in the utility model bearing groove, cooler is the cooling water pipe of coil pipe dress, and cooling water pipe enters to be attached on the madial wall of described outer ring, and cooler one end is water inlet, and the other end is delivery port.By the effect of cooler, cool bearing groove, lubricating oil cools, and viscosity would not reduce, and also cools bearing by lubricating oil, the object that lubricating oil not only plays lubrication also serve cooling effect that, extend the useful life of bearing.
