Abstract
The utility model provides a prevent generator rotor of static corruption, include axle and the claw utmost point, field coil, the collecting ring that assemble with it, the wire that the collecting ring contains under sliding ring in sliding ring on collecting ring bakelite, the collecting ring, the collecting ring, the collecting ring sliding ring and is connected with them, when the axle was gone into in the collecting ring pressure equipment, it realized switching on through wire interference fit with the axle. The utility model discloses need not change except that the collecting ring other the motor component that sends out, adopt new collecting ring structure can realize that prevent static electricity corrodes, used collecting ring simple structure is reliable, and the cost change is little.
Description
Technical field
The utility model relates to a kind of generator amature, especially a kind of generator amature of antistatic corrosion.
Background technology
Most of automobile current generators on market do not possess antistatic corrosion function, and the electrostatic produced under some operating mode corrosion can damage dynamo bearing and then cause generator to run, and therefore need to provide a antistatic to corrode generator.
Most of generator rotor structures (as Fig. 1) on market, collector ring adopts two slip ring structures.Dynamo belt and belt pulley (5) fricative electrostatic charge by axle (4) passed to assemble with it fore bearing (6), back-up ring (7), pawl pole (2), collector ring bakelite (12), rear bearing (15).Wherein only have fore bearing (6), rear bearing 15) directly contact with generator housing (housing is equivalent to ground connection), back-up ring (7), pawl pole (2), collector ring bakelite (12) over the ground (or negative pole) nothing directly contact, and the electrostatic charge therefore produced only can reach generator housing (housing is equivalent to ground connection) by bearing.When generator runs up, lubricating grease (a) resistance on bearing ball surface is close to insulation (M Ω rank) very greatly, and the thin oil film of this one deck is very easily produced high temperature by electrostatic breakdown and produces harm to lubricating grease and ball working face, causes bearing damage.
Summary of the invention
For the problems referred to above, main purpose of the present utility model is the generator amature providing a kind of antistatic to corrode, and the generator mated with described rotor can prevent electrostatic corrosion phenomenon from occurring by release electrostatic.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of generator amature of antistatic corrosion, comprise axle and the pawl pole of assembling with it, field coil, collector ring, the wire that described collector ring to comprise on collector ring bakelite, collector ring in slip ring, collector ring slip ring under slip ring, collector ring and is connected with them, when described collector ring presses fit into axle, itself and axle interference fit realize conducting.
As further preferred, described collector ring is connected with brush E, F, and brush E is ground connection or negative pole.
As further preferred, described brush F connection adjustor.
As further preferred, described brush E contacts with slip ring in slip ring, collector ring on collector ring simultaneously, and brush F and collector ring downslide loop contacts, field coil circuit obtains closed loop conducting, does not affect former Generator Voltage Regulation.
As further preferably, when described collector ring presses fit into axle, realize conducting by wire described in its part and axle interference fit.
As further preferred, on described collector ring, slip ring and axle realize conducting by wire.
As further preferred, on described collector ring in slip ring, collector ring under slip ring and collector ring in slip ring three the slip ring spacing of any two be not more than 0.5mm, have enough air gaps, single rotor sensing chamber collector ring three slip rings can carry out normal Hi-pot test.
As further preferably, on described collector ring in slip ring, collector ring under slip ring and collector ring in slip ring three the slip ring spacing of any two be 0.5mm.
As further preferably, slip ring spacing 0.5mm in slip ring and collector ring on described collector ring.
The beneficial effects of the utility model are: compared with background technology, the utility model does not need to change other generator parts except collector ring, adopt new collecting ring can realize preventing electrostatic from corroding, collecting ring used is simple and reliable, and cost change is little.
