Description
【０００１】[0001]
本考案は回転子コイルと回転子軸との絶縁を図る絶縁管を備えた電動機回転子 に関するものである。 The present invention relates to an electric motor rotor provided with an insulating tube for insulating a rotor coil from a rotor shaft.
【０００２】[0002]
従来の電動機回転子は、回転子コイル５と回転子軸２との電気絶縁を図るため に、図４に示すように回転子軸２に絶縁管６を固着している。該絶縁管６と整流 子７は接着剤を介して回転子軸２に固着されていた。 In the conventional motor rotor, an insulating tube 6 is fixed to the rotor shaft 2 as shown in FIG. 4 in order to electrically insulate the rotor coil 5 from the rotor shaft 2. The insulating tube 6 and the commutator 7 were fixed to the rotor shaft 2 with an adhesive.
【０００３】[0003]
従来の電動機回転子では、回転子軸２に絶縁管６及び整流子７を固着するのに 接着剤を用いていたため、作業性が悪く機械化に対応出来ないという問題があっ た。 本考案の目的は、回転子軸に絶縁管及び整流子を固着する際の作業性を向上さ せることである。 In the conventional motor rotor, since the adhesive is used to fix the insulating tube 6 and the commutator 7 to the rotor shaft 2, the workability is poor and the mechanization cannot be applied. An object of the present invention is to improve workability when fixing an insulating tube and a commutator to a rotor shaft.
【０００４】[0004]
上記目的は、絶縁管の回転子鉄心及び整流子に当接する端面に少なくとも１個 の溝を設けることにより達成される。 The above object is achieved by providing at least one groove in the end surface of the insulating tube that abuts the rotor core and the commutator.
【０００５】[0005]
上記のように構成された電動機回転子には、絶縁管の回転子鉄心及び整流子と の当接部に溝が形成されているため、該溝が回転子コイル巻回後のワニス処理時 に絶縁管内周部及び整流子内周部へのワニス侵入を促す。 Since the motor rotor configured as described above has a groove formed in the contact portion between the rotor core of the insulating tube and the commutator, the groove is formed at the time of varnish treatment after winding the rotor coil. Encourage the varnish to enter the inner circumference of the insulation tube and commutator.
【０００６】[0006]
図１〜図３を用いて本考案の一実施例を説明する。 図１に示す電動機回転子において、外周表面に突起１を形成する回転子軸２を 回転子鉄心３に圧入する。該回転子鉄心３の両端面には樹脂４が融着されており 、回転子コイル５と回転子鉄心３を電気的に絶縁している。絶縁管６は回転子鉄 心３を挾んで２個設けられており、回転子軸２を覆いながら回転子鉄心３の両端 面に当接し、一方の絶縁管６の回転子鉄心に当接しない端面には整流子７が当接 している。 An embodiment of the present invention will be described with reference to FIGS. In the electric motor rotor shown in FIG. 1, a rotor shaft 2 forming a protrusion 1 on the outer peripheral surface is press-fitted into a rotor core 3. Resin 4 is fused to both end surfaces of the rotor core 3 to electrically insulate the rotor coil 5 and the rotor core 3. Two insulating tubes 6 are provided sandwiching the rotor core 3, and contact the both end surfaces of the rotor core 3 while covering the rotor shaft 2 and do not contact the rotor core of one insulating tube 6. The commutator 7 is in contact with the end surface.
【０００７】 図１に示す実施例では、回転子コイル５を巻回後ワニス処理を行うことにより 、絶縁管６の両端面に設けた複数個の溝にワニスが入り込み、回転子鉄心３、絶 縁管６及び整流子７の内周面と、回転子軸２の表面との空隙部９にワニスが侵入 して絶縁管６を回転子軸２に固着する。In the embodiment shown in FIG. 1, by varnishing the rotor coil 5 after winding it, the varnish enters a plurality of grooves provided on both end surfaces of the insulating pipe 6, and the rotor core 3 and The varnish enters the space 9 between the inner peripheral surfaces of the edge tube 6 and the commutator 7 and the surface of the rotor shaft 2 to fix the insulating tube 6 to the rotor shaft 2.
【０００８】[0008]
本考案によれば、絶縁管の当接部に溝を設けたので、絶縁管及び整流子内周部 までワニスの侵入が促され、接着剤を使用せずに回転子コイル巻回後のワニス処 理を施すだけで、絶縁管及び整流子を回転子軸に固着することができる。 According to the present invention, since the groove is provided in the abutting portion of the insulating pipe, the varnish is promoted to reach the insulating pipe and the inner peripheral portion of the commutator, and the varnish after winding the rotor coil is used without using an adhesive. The insulating tube and the commutator can be fixed to the rotor shaft only by performing processing.
