본 발명은 트윈기어 구조의 기어드 스텝핑 모터에 관한 것으로서, 보다 상세히는 스텝핑 모터의 기어열 구조를 기존 사출기어로써 기어의 강도 및 내구성을 향상시킨 트윈기어 구조의 기어드 스텝핑 모터에 관한 것이다.The present invention relates to a geared stepping motor of a twin gear structure, and more particularly, to a geared stepping motor of a twin gear structure that improves the strength and durability of the gear using the gear train structure of the stepping motor as an existing injection gear.

도 1을 참조하면, 종래의 기어드 스텝핑 모터의 기어열 구조는 로터기어(10)에 맞물리는 제1기어의 대기어(14)와, 제1기어의 소기어(12)에 맞물리는 제2기어의 대기어(18)와, 제2기어의 소기어(16)에 맞물리는 제3기어의 대기어(22)와, 제3기어의 소기어(20)에 맞물리는 출력기어(26)로 구성된다.Referring to FIG. 1, a gear train structure of a conventional geared stepping motor includes a standby gear 14 of a first gear engaged with a rotor gear 10 and a second gear engaged with a small gear 12 of a first gear. Air gear 18 of the third gear, the air gear 22 of the third gear meshing with the small gear 16 of the second gear, and the output gear 26 meshing with the small gear 20 of the third gear. do.

이와같은 종래의 기어드 스텝핑 모터의 기어열 구조는 로터기어(10)와 출력기어(26) 사이에 제1기어, 제2기어, 제3기어의 3개의 감속 기어가 포함되어, 감속비가 1/64가 된다. The gear train structure of the conventional geared stepping motor includes three reduction gears of the first gear, the second gear, and the third gear between the rotor gear 10 and the output gear 26, and the reduction ratio is 1/64. Becomes

그러므로, 종래의 기어드 스텝핑 모터의 기어열 구조는 감속기어의 수가 많아 기어 배치를 위한 공간 여유가 없으며, 좁은 공간에 감속기어를 배치하기 위해서는 기어가 작아지게 되고, 작은 기어 강도를 보강하기 위하여 철계 또는 소결 기어로 강도를 보강하여 왔으나 이는 부품 단가 인상을 초래하여 효과적이지 못하였다. Therefore, the gear train structure of the conventional geared stepping motor has a large number of reduction gears, so there is no space for gear arrangement, and the gears become smaller in order to arrange the reduction gears in a narrow space. Strength has been reinforced with sintered gears, but this has resulted in an increase in the cost of parts, which has not been effective.

본 발명은 상술한 종래의 문제점을 극복하기 위한 것으로, 본 발명의 목적은 트윈기어의 적용으로 기어의 재질을 철계, 동계, 소결 기어로 변경하지 않고 기존 사출기어로도 강도를 향상시키는 효과를 가진 트윈기어 구조의 기어드 스텝핑 모터를 제공하는데 있다.The present invention is to overcome the above-mentioned conventional problems, an object of the present invention is to apply a twin gear twin without having to change the material of the gear to iron, copper, sintered gear to improve the strength of the existing injection gear It is to provide a geared stepping motor with a gear structure.

본 발명에 따른 트윈기어 구조의 기어드 스텝핑 모터의 일예로서,As an example of a geared stepping motor having a twin gear structure according to the present invention,

제1기어의 소기어에 맞물리는 제2기어의 대기어와, The standby gear of the second gear meshing with the small gear of the first gear,

제2기어의 소기어에 맞물리는 출력기어로 구성되며,It consists of an output gear meshing with the small gear of the second gear,

상기 제 1 기어와 상기 제 2 기어는 상기 로터 기어를 중심으로 상호 대칭으로 배치된다.The first gear and the second gear are arranged symmetrically with respect to the rotor gear.

본 발명에 따른 트윈기어 구조의 기어드 스텝핑 모터는 2가지의 감속기어를 각각 대칭적으로 배치하여, 감속비를 1/32로 낮추었고, 감속기어 종류의 수를 감소시킴으로써, 기어가 배치될 공간의 여유를 확보할 수 있으며, 제1기어 및 제2기어 의 대칭적 구조로 인하여 기어 강도를 보강할 수 있으며, 제1기어 및 제2기어를 대칭적으로 배치하여 각 기어치에 받는 부하를 절반으로 감소시켜 재질을 철계, 동계, 소계 기어로 변경하는 것 없이 기어의 내구성을 향상시킬 수 있는 효과가 있다.In the geared stepping motor of the twin gear structure according to the present invention, two reduction gears are symmetrically arranged to reduce the reduction ratio to 1/32, and the number of reduction gear types is reduced, thereby allowing the space for the gear to be arranged. And the gear strength can be reinforced by the symmetrical structure of the first gear and the second gear, and the load applied to each gear tooth is halved by symmetrically placing the first gear and the second gear. It is possible to improve the durability of the gear without changing the material to iron-based, copper-based, sub-gear gear.

여기에서 설명한 것은 본 발명에 따른 트윈기어 구조의 기어드 스텝핑 모터를 실시하기 위한 하나의 실시예에 불과한 것으로서, 본 발명은 본 실시예에 한정되지 않고, 이하의 특허청구의 범위에서 청구하는 바와 같이 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능한 범위까지 본 발명의 기술적 정신이 있다고 할 것이다.What has been described herein is only one embodiment for implementing a geared stepping motor of a twin gear structure according to the present invention, and the present invention is not limited to this embodiment, as claimed in the following claims. Without departing from the gist of the invention, anyone of ordinary skill in the art to which the present invention will have the technical spirit of the present invention to the extent that various modifications can be made.

이하, 본 발명의 실시예를 첨부 도면을 참조하여 설명하기로 한다. Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

The small gear 63 of the second gear meshes with the output gear 70.

제1기어는 상호 대칭적으로 배치되어, 로터기어(50)에 제1기어의 대기어(52, 56)가 각각 맞물리게 할 수 있다. The first gears may be arranged symmetrically with each other so that the standby gears 52 and 56 of the first gear mesh with the rotor gear 50, respectively.

제2기어는 상호 대칭적으로 배치되어, 제1기어의 소기어(53, 57)에 제2기어의 대기어(61, 65)가 각각 맞물리게 할 수 있다. The second gears are arranged symmetrically to each other so that the standby gears 61 and 65 of the second gear mesh with the small gears 53 and 57 of the first gear, respectively.

제2기어의 소기어(63, 66)는 출력기어(70)에 각각 맞물린다.The small gears 63 and 66 of the second gear mesh with the output gears 70, respectively.

본 발명에 따른 기어드 스텝핑 모터의 트윈기어 구조는 2가지의 감속기어 즉 제1기어와 제2기어의 기어 치수를 짝수로써 대칭적으로 배치하여, 감속비를 1/32로 낮추었고, 감속기어 종류의 수를 감소시킴으로써, 기어가 배치될 공간의 여유를 확보할 수 있으며, 제1기어 및 제2기어의 대칭적 구조로 인하여 기어 강도를 보강할 수 있다.The twin gear structure of the geared stepping motor according to the present invention symmetrically arranges the gear sizes of two reduction gears, namely, the first gear and the second gear, to reduce the reduction ratio to 1/32, By reducing the number, it is possible to secure a space in which the gear is to be arranged, and to reinforce the gear strength due to the symmetrical structure of the first gear and the second gear.
