Description

회전자의 임펠라고정방법{a turning rotor of impeller fixing method}{A turning rotor of impeller fixing method}

본 발명은 핸드피스의 내부에 내장되는 모터를 구성하는 회전자의 저면에 결합되어 동시에 회전하면서 모터의 열을 외부로 방출하도록 하는 역활을 담당하는 임펠라를 회전자에 결합하기 위한 회전자의 임펠라고정방법에 관한 것으로 특히, 상기 회전자에 임펠라의 고정설치를 용이하게 함은 물론 고정설치된 임펠라가 회전자의 중심선과 편심되지 않고 정확하게 일치하도록 하여 회전자의 회전이 용이하도록 한 것이다.The present invention is coupled to the bottom of the rotor constituting the motor built into the handpiece, the impeller of the rotor for coupling to the rotor impeller that plays a role to release the heat of the motor to the outside while rotating at the same time In particular, the method is to facilitate the fixed installation of the impeller to the rotor, as well as to ensure that the fixed installed impeller is precisely matched to the center line of the rotor without eccentricity to facilitate the rotation of the rotor.

일반적으로 핸드피스의 내부에 내장되는 모터를 구성하는 회전자의 저면에 는 모터의 열을 외부로 방출하도록 임펠라를 고정설치하는데 종래에는 회전자에 임펠라를 고정설치하는 방법으로 첨부도면 도1에 도시된 바와 같이 회전자(10)의 코아(철심)(11)와 정류자(20)사이의 목부분에 실(30)등을 감은다음 임펠라(40)를 결합한후 에폭시수지로 몰딩하여서 임펠라(40)를 고정설치하였는바, 이와같은 임펠라고정방법은 임펠라(40)가 코아(철심)(11)와 정류자(20)사이의 목부분에 불규칙하게 실(30)등을 감은 다음 결합되는 관계로 회전자(10)의 중심축선과 임펠라(40)의 중심축선이 정확하게 일치되지 않을 뿐만 아니라 에폭시수지가 고르게 주입이 안됨으로서 무게중심이 일일측으로 치우치게 되는등 회전자(10)의 중심축선과 임펠라(40)의 중신축선이 정확하게 일치되도록 결합하기가 거의 불가능하였다.In general, the impeller is fixed to the bottom of the rotor constituting the motor embedded in the handpiece to discharge heat from the motor. Conventionally, the impeller is fixedly installed on the rotor as shown in FIG. As described above, the thread 30 is wound around the neck portion between the core 11 of the rotor 10 and the commutator 20, and then the impeller 40 is bonded and then molded with an epoxy resin to form an impeller 40. The impeller fixed method is such that the impeller 40 is wound around the core between the core (iron core) 11 and the commutator 20 irregularly wound around the thread 30 and then coupled to the rotor The center axis of the rotor 10 and the center axis of the impeller 40 are not exactly matched, and the center of gravity and the impeller 40 of the rotor 10 are biased toward one side due to the epoxy resin being not evenly injected. The central axis of It was almost impossible to combine as much as possible.

따라서 회전자에 임펠라(40)를 결합하기가 매우 까다로웠을 뿐만아니라 상기 회전자(10)의 회전시 떨림현상이 생겨 회전자(10)의 회전이 용이하지 않았음은 물론 회전자(10)와 임펠라(40)의 편심차를 보상하기 위해서 회전자(10)의 코아(11)표면을 여기저기 깍아내면서 편심을 보상하는 매우 어려운 작업을 병행하여야 하는 문제점이 있었다.Therefore, not only it was very difficult to couple the impeller 40 to the rotor, but also the shaking phenomenon occurred when the rotor 10 rotated, and the rotor 10 was not easily rotated as well as the rotor 10. In order to compensate for the eccentricity of the impeller 40, the core 11 of the rotor 10 was scraped up and down, and there was a problem that a very difficult task of compensating the eccentricity had to be performed in parallel.

본 발명은 상기와 같은 종래의 회전자에 임펠라를 결합하는 방법에서 발생하는 제반 문제점등을 감안 하여 안출한 것으로, 상기 회전자에 임펠라의 고정설치시 회전자의 중심축선과 이에 결합되는 임펠라의 중심축선이 정확히 일치하도록 임펠라고정방법을 제공하여 임펠라의 고정설치를 용이하도록 함은 물론 결함후 회전자의 중심축선과 일임펠라의 중식축선이 편심되지 않고 정확하게 일치하도록 하여 회전자의 회전이 용이하도록 하여 제품의 성능을 높히도록 함에 그 목적을 둔 것이다.The present invention has been made in view of various problems, such as occurring in the method of coupling the impeller to the conventional rotor as described above, the center axis of the rotor when the impeller is fixed to the rotor and the center of the impeller coupled thereto Impeller-fixing method is provided to make the axis coincide exactly, and the impeller can be fixed and installed easily. Also, the center axis of the rotor after the defect and the feeding axis of the impeller are not eccentric but precisely matched to facilitate the rotation of the rotor. The purpose is to increase the performance of the product.

상기와 같은 목적을 달성하기 위한 본 고안은 첨부도면 도2 내지 도3에 도시된 바와같이 고속회전하는 모터에서 발생하는 열을 방출하기 위해서 외주면에 적어도 2개이상의 날개(301)를 형성한 임펠라(300)를 회전자(100)에 결합함에 있어서,The present invention for achieving the above object is an impeller having at least two wings 301 formed on the outer circumferential surface in order to dissipate heat generated from a high-speed rotating motor as shown in the accompanying drawings In coupling 300 to the rotor 100,

상기 회전자(100)를 구성하는 코아(101)의 코일홈(101a)에 감겨있는 코일(102)을 보호하기 위하여 코일홈(101a)에 코일보호용 쐐기편(200)을 결합하되, 상기 코일보호용 쐐기편(200)의 하단을 전부 회전자(100) 하측으로 길게 돌출 되도록 결합한다음 임펠라(300)의 내주면을 코일보호용 쐐기편(200)의 외면에 결합한후에 에폭시수지를 주입하여서 이루어 진다.In order to protect the coil 102 wound around the coil groove 101a of the core 101 constituting the rotor 100, the coil protection wedge 200 is coupled to the coil groove 101a, but the coil protection The lower ends of the wedge pieces 200 are all combined to protrude to the lower side of the rotor 100, and then the epoxy resin is injected after the inner circumferential surface of the impeller 300 is coupled to the outer surface of the wedge piece 200 for coil protection.

여기서 상기 미설명 부호 103은 정류자이다.Here, the reference numeral 103 is a commutator.

상기와 같은 방법에 의해 회전자(100)에 임펠라(300)를 고정결합하게 되면, 회전자(100)의 중심축선과 임펠라(300)의 중심축선이 정확히 일치된다.When the impeller 300 is fixedly coupled to the rotor 100 by the above method, the center axis line of the rotor 100 and the center axis line of the impeller 300 are exactly matched.

따라서 상기 회전자(100)를 자성체인 고정자(도시하지 않음)의 내부로 삽입하여 모터를 구성하고 전원을 인가하면 임펠라(300)의 중심축선이 회전자(100)의 중심축선과 일치하기 때문에 회전자(100)의 떨림현상이 전혀 없어 회전자(100)의 회전이 용이하다.Therefore, when the rotor 100 is inserted into the stator (not shown), which is a magnetic body, and the motor is configured and power is applied, the center axis of the impeller 300 coincides with the center axis of the rotor 100. Rotation of the rotor 100 is easy because there is no vibration of the electrons 100.

상기와 같은 본 발명의 회전자에 임펠라를 고정하는 방법을 이용하게 되면 임펠라의 고정설치가 매우 간편하여 누구라도 손쉽게 회전자에 임펠라를 아주 간단하고 손쉬우며 빠르게 고정설치 할 수 있음은 물론, 무엇보다도 상기 회전자에 임펠라를 고정설치시 회전자의 중심축선과 이에 결합되는 임펠라의 중심축선이 편심되지 않고 정확하게 일치됨으로써, 회전자의 회전시 떨림현상이 전혀없어 회전자의 회전이 용이한등 전체적으로 고품질의 모터의 생산이 가능하여 실사용자의 편의를 도모할 수 있는 매우 획기적이며 신규유용한 발명이다.If the method of fixing the impeller to the rotor of the present invention as described above is very easy to install the impeller anyone can easily install the impeller on the rotor very simple, easy and fast, of course, what Rather, when the impeller is fixed to the rotor, the center axis of the rotor and the center axis of the impeller coupled thereto are not exactly eccentric, so that there is no tremor during rotation of the rotor, so that the rotor is easily rotated. It is a very innovative and useful invention that can produce high-quality motors, which can promote the convenience of real users.
