Abstract
The utility model discloses a sealed generator. The sealed generator comprises a rotor, a stator, shafts, a protection cover, front bearings, back bearings, an electric brush assembly and a capacitor, wherein a rotor shaft is fixedly connected with the rotor, a stator shaft is fixedly connected with the stator, the stator is fixed by a pin which is arranged axially, the stator shaft and the rotor shaft are internally provided with a through-shaft, the through-shaft is borne in the stator shaft through two front bearings in the stator shaft, the front bearings are respectively fixed through two snap rings axially, the rotor is respectively borne on the stator shaft through two back bearings in the rotor shaft, the electric brush assembly and the capacitor are arranged in the protection cover, the protection cover is internally provided with a rubber sealing pad, and the electric brush assembly is provided with a rubber protection sleeve. According to the sealed generator, when the sealed generator is at work, brush powder caused by electric brush friction on a collection ring is accumulated in a sealed chamber, so the electric brush powder is prevented from flowing onto other electric parts.
Description
Technical field
The utility model relates to a kind of generator, particularly relates to a kind of closed type generator.
Background technology
In the process of generator work, brush friction collector ring and the brush dust that forms can descend slowly and lightly on other electric components of automobile, thereby pollute other electric parts.The harm that sucks the carbon brush dust in the generating hood has: one, make slip ring insulation against ground variation, two, stator and rotor winding insulation are descended, three, stop up iron core and make wind duct temperature increase, four, the easy moisture absorption of generator.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of closed type generator is provided.
For achieving the above object, technical solution adopted in the utility model is as follows.
A kind of closed type generator, comprise rotor, stator, axle, over cap, fore bearing, rear bearing, brush assembly of electric and electric capacity, armature spindle is fixedly connected with described rotor, is fixedly connected with stator on stator axis, described stator is fixed by the pin of axial placement, is provided with axis in stator axis and armature spindle; Described axis is bearing in stator axis by two fore bearings in described stator axis, and described fore bearing is respectively by two jump ring axial restraints, and described rotor is bearing in respectively on described stator axis by two rear bearings in described armature spindle; Described brush assembly of electric and described electric capacity are arranged in over cap; Be provided with rubber gasket in described over cap, described brush assembly of electric is provided with rubber protecting jacket.
Further, the outside of described fore bearing and described rear bearing is equipped with fan.
Further, described brush is the extended type brush.
The beneficial effects of the utility model are: adopt closed type generator of the present utility model, in the process of generator work, because the brush dust that the brush friction collector ring forms can be hoarded in the closed chamber the inside, thereby prevented that the brush dust from descending slowly and lightly on other electric components.
Description of drawings
Fig. 1 is the structural representation of closed type generator of the present utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Closed type generator of the present utility model comprises rotor 7, stator 3, axle, over cap 12, fore bearing 6, rear bearing 9, brush assembly of electric 13 and electric capacity as shown in Figure 1.Armature spindle 8 is fixedly connected with rotor 7, is fixedly connected with stator 3 on stator axis 4, and stator 3 is fixing by the pin 5 of axial placement, is provided with axis 1 in stator axis 4 and armature spindle 8.Axis 1 is bearing in stator axis 4 by two fore bearings 6 in stator axis 4, and fore bearing 6 is respectively by two jump ring 2 axial restraints, and rotor 7 is bearing in respectively on stator axis 4 by two rear bearings 9 in armature spindle 8, and rotor 7 is fixing by the bolt 10 of axial placement.Brush assembly of electric 13 and electric capacity are arranged in over cap 12.Be provided with rubber gasket 11 in over cap 12, brush assembly of electric 13 is provided with rubber protecting jacket 14.
When assembling generator of the present utility model, first rubber gasket 11 is arranged in over cap 12, then brush assembly of electric 13 with rubber protecting jacket 14 is installed, over cap 12 is installed at last.Like this, make brush in complete totally enclosed sealing office work.The space of brush work has been totally enclosed closed chamber, in the process of generator work, because the brush dust that the brush friction collector ring forms can be hoarded in the closed chamber the inside, thereby has prevented that the brush dust from descending slowly and lightly on other electric components.
For lowering bearing working temperature, prolongation bearing life on every side, be equipped with fan (not shown) in the outside of fore bearing 6 and rear bearing 9.Built-in fans can reduce the temperature around front and back bearings effectively.
As preferably, the brush of closed type generator of the present utility model is the extended type brush, the steady quality of extended type brush, and its effective time significantly improves, thereby greatly extends the life-span of generator.
The above is only preferred embodiment of the present utility model, is not to limit practical range of the present utility model; If do not break away from spirit and scope of the present utility model, the utility model is modified or is equal to replacement, all should be encompassed in the middle of the protection range of the utility model claim.
