Abstract
The invention discloses a rotor, comprising a rotor shaft and an iron core; and an insulation layer is arranged between the rotor shaft and the iron core. The insulation layer as a scheme I is formed by a plurality of uniformly distributed arc pieces which are spiral; the rotary direction of the rotor can meet the condition of enabling air flows to enter the spiral shapes. When entering into the arc pieces, the air flows can carry the heat away to reduce the temperature in the rotor, particularly the temperature of the arc pieces, thus further improving the insulation performance of the insulation layer. The include angle A between the spiral shapes and the rotary shaft is 15-30 degrees. The insulation layer is a hollow cylinder. A plurality of through slots are formed at the circumferential face of the hollow cylinder. The insulation layer is made of epoxy glass fibers. The invention also provides a starter of a motor, and the starter comprises a starter shell internally provided with a stator and an end cover as well as a carbon brush assembly and the rotor. The rotor with the insulated rotor shaft and iron core and the starter of the relevant motor have the beneficial effects of simple structure, low cost, convenience in machining, high-temperature resistance and long service life.
Description
Technical field
The present invention relates to a kind of rotor, between the armature spindle of this rotor and iron core, insulating barrier is set, also relate to the starter of the engine that uses this rotor, also relate to and used the motor vehicle that the engine starter of insulating barrier is set between armature spindle, iron core.
Background technology
in prior art, the armature spindle of automotive engine starter rotor is directly to be connected with iron core, armature spindle, the shell of iron core and starter is electrically connected to the automobile frame and as the negative pole of battery, automotive engine starter is when igniting, for various reasons as winter temperature low, the duration of ignition is too short, oil circuit is not smooth, cell voltage is on the low side etc., the situation that there will be continuous several times starting ignition or long-time starting ignition, starter can produce the pulsating current greater than 500A while starting, make coil windings produce vibrations, produce simultaneously high temperature, can reach more than 300 ℃, usually, the coil windings of starter armature and the insulating barrier between iron core adopt C class F insulation paper, the highest can only bearing temperature 220 ℃, under the double action of vibrations and high temperature, insulating paper is softening, damaged, coil windings and iron core short circuit finally appear, at this moment, the coil windings that the positive pole of power supply is connected by commutator segment is directly linked armature spindle and the shell as power cathode, current surge, in addition, we know, the contact resistance of commutator segment is relatively large, the performance of holding heat is also relatively poor, during short circuit current process commutator segment, produce large spark, make commutator segment softening, wherein, always having a or two commutator segment takes the lead in damaging, cause that the row of jumping is that the commutator segment perk breaks away from commutator, damage commutator, the final starter that damages.
Summary of the invention
The present invention, according to above deficiency, provides a kind of rotor, and by armature spindle and iron core mutual insulating, electric flowing through coil winding, iron core, the armature spindle short circuit of having stopped anode are back to battery cathode.
Technical scheme of the present invention is:
A kind of rotor comprises: armature spindle, iron core are provided with insulating barrier between armature spindle, iron core.
For this insulating barrier can be set, between armature spindle, iron core, leave gap, can reduce the diameter of armature spindle, or, can enlarge the aperture of iron core, or the diameter that namely reduces armature spindle enlarges again the aperture of iron core, thereby reserve gap.
Insulating barrier can be the form acquisition by injection moulding, also can first insulating barrier be processed, and refills and is fitted between armature spindle and iron core.
As one of scheme, described insulating barrier is comprised of some uniform arc plates.
Further, twist, the direction that rotor rotates meets can make air-flow enter in spirality to described arc plate.In the time of in air-flow enters spiral arc plate, heat can be taken away, reduce the internal temperature of rotor, particularly reduce the temperature of arc plate, further improve the insulation property of insulating barrier.
As preferably, the axial included angle A of described spirality and armature spindle is the 15-30 degree.
As one of preferred version, described insulating barrier is hollow cylinder.This scheme is easy to process, processing cost is low.
Further, on the periphery of described hollow cylinder, offer some grooves.Can increase the heat radiation gap.
As preferably, described insulating barrier is made by epoxy glass fiber.
The present invention also provides a kind of starter of engine, comprises starter housing, the carbon brush component of stator and end cap, also comprises described rotor.
That the present invention has is simple in structure, cost is low, the beneficial effect of easy to process, high temperature resistance, long service life.
The accompanying drawing explanation
Fig. 1 is cutaway view of the present invention.
Fig. 2 is the end view that insulating barrier of the present invention adopts circular arc sheet.
Fig. 3 is the end view that insulating barrier of the present invention adopts the spirality circular arc sheet.
Fig. 4 is the end view that insulating barrier of the present invention adopts hollow cylinder.
Fig. 5 is that insulating barrier of the present invention adopts the end view with the hollow cylinder of groove.
Embodiment
Now the present invention is further illustrated by reference to the accompanying drawings:
As shown in the figure, a kind of rotor comprises: commutator 1, iron core 2 coil windings 4, armature spindle 5 are provided with insulating barrier 3 between armature spindle 5, iron core 2.
Insulating barrier 3 can be comprised of some uniform arc plates 31.
Arc plate can also be selected spirality 32, and the direction C that rotor rotates meets can make air-flow B enter in spirality.
Spirality 32 is the 15-30 degree with the axial included angle A of armature spindle 5.
Insulating barrier 3 can also be selected hollow cylinder.
As one of embodiment, on the periphery of hollow cylinder, offer some grooves 33.
Insulating barrier 3 can select epoxy glass fiber to make.
A kind of starter of engine, comprise starter housing, the carbon brush component of stator and end cap and above-mentioned rotor.
With starter of rotor assembling of the present invention, no-load running on testing stand, after having moved 5 minutes, spark has strengthened a little, but starter or normal operation; After continuing to run until 10 minutes, starter or normal operation, but the starter temperature is very high.Out of service, take starter apart, find that rotor, commutator turn black, but commutator cylindrical or normal does not damage.
With starter of the rotor of prior art assembling, no-load running on testing stand, moving more than 4 minutes after clock, spark is very large, and starter can not run well.Take starter apart, find the row of jumping of commutator segment.
The present invention is insulated between armature spindle 5 and iron core 2, rotor integral body can not be short-circuited when certain of the coil windings 4 in iron core 2 and iron core 2 are short-circuited, only have rotor integral body when at least two place's coil windings 4 in iron core 2 are short-circuited with iron core 2 just can affect, the particular location of two place's coil windings 4 is also depended in the impact of this moment, if two very approaching place's coil windings 4 of path be short-circuited also affect very little, therefore, the present invention greatly reduces the short circuit probability, has extended useful life.
The foregoing is only preferred embodiment of the present invention, with this, do not limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
