Application number is that 200620070424.6 Chinese patent discloses a kind of commutator neck bush, comprises bush body, and the outer surface of bush body is provided with several groove, and the section of groove is swallow-tail form; Bush body is made by aluminium, and the angle of its groove floor and side is not less than 45 °.But this lining haves much room for improvement in processing characteristics, and easily mobile in commutator, thereby influences the serviceability of commutator.
Summary of the invention
The utility model mainly provides a kind of spiral bushing and commutator thereof, and its lining good processability can prevent lining axial and movement radially in commutator, and save cost.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: spiral bushing of the present utility model comprises the spiral bushing body that is formed by some spiral coils, and described spiral bushing body is provided with the some boss that form the gap between the adjacent described spiral coil that makes on the spiral bushing body.Traditional copper sheathing and iron cover are owing to can not use cutting fluid processing, so precision only can reach copper sheathing H6 level, iron cover H7 level by numerically controlled lathe, the utility model is compared with the bush structure of traditional copper, steel, good processability, namely just can reach the H6-H7 class precision by returning the hole reamer, make a power of going into of commutator stablize, when not destroying the commutator mechanical characteristic, can bear and go into a power requirement more greatly, thereby commutator and motor shaft assembling are played a protective role; And traditional copper sheathing and steel lining are that thunder silk or online article by outer round surface prevents that lining from radially rotating in commutator, control the axial displacement of lining by cannelure, this can't fundamentally be avoided lining under the effect of external force, takes place axially and displacement radially; Have again, spiral bushing of the present utility model can and the abundant combination of bakelite, lining integral body is covered by phenolic moulding powder fully, himself structure is also highly stable, fundamentally stopped under bigger external force effect, lining in commutator axially with radially movement.
As preferably, described spiral coil is made by wire, and described cross section wiry comprises the side of two convex arc wire.The utility model adopts the side of convex arc wire, and when commutator injected phenolic moulding powder, this physical efficiency of spiral bushing was wrapped in the phenolic moulding powder fully like this, do not come out from the commutator inner hole wall, cause wearing and tearing, and when adopting rectilinear side, the spiral bushing body easily comes out, and is easy to generate wearing and tearing.Wire can adopt steel wire and copper wire etc.
As preferably, described wire also comprises plane upper surface and lower surface.
As preferably, described boss is arranged on the described upper surface, and described boss comprises plane boss upper surface and two vertical planar boss side surfaces.
As preferably, the adjacent described spiral coil contact that described boss upper surface is relative with it.Make that like this gap is very little, only caused by the boss that forms, simultaneously boss contacts with adjacent spiral coil again, overall structure is stable, the intensity height, can guarantee in the distance between adjacent spiral bushing under the high pressure 28-30Mpa axial compressive force constantly, can avoid spiral bushing in commutator, to move radially like this.
As preferably, be provided with three boss on each described spiral coil at least.
As preferably, described spiral bushing is whole coil structures.Whole coil structures is that spiral bushing first lap spiral coil adds that the last lap spiral coil constitutes a complete helix circle, thereby make that the number of turns of spiral coil is integer on the spiral bushing, as can being that spiral bushing first lap spiral coil and last lap spiral coil are the semi-annular shape circle, whole coil structures is not limited to enclose up and down two half-turns, as long as can constitute whole circle; Adopt whole coil structures to make that commutator radial direction quality is even, good dynamic balance adopts the spiral bushing of this whole coil structures to make commutator realize dynamic balancing when commutator rotates at a high speed.
Commutator of the present utility model comprises the commutator body and is arranged on the intrinsic described spiral bushing of described commutator that at least one end of the intrinsic described spiral bushing of commutator is provided with the positioning step that some and described spiral bushing matches.Positioning step of the present utility model plays the effect that holds up spiral bushing, bears the concentric force of spiral bushing, makes spiral bushing obtain firm support, has strengthened the integral rigidity of commutator.
As preferably, described positioning step is projection cube structure.
As preferably, described commutator body comprises commutator segment and phenolic moulding powder, and described positioning step is along the axle center circumferential arrangement of commutator body.
The beneficial effect that the utility model brings is, the utility model good processability can bear and go into a power requirement more greatly, prevents lining axial and movement radially in commutator, and reduced cost, cost of the present utility model only be copper lining 1/8, iron cover 1/6.
