Abstract

본 발명은 정밀 소형 스텝모우터(Step Moter)의 백스프링(Back Spring)부위의 변경을 통하여 모우터와 회전자의 센터링(Centering)을 좋게하면서도 조립성을 향상시켜서 편심등에 기인하여써던 소음과 진동 또는 위치결정 에러(Error)등의 단점을 보완하여 모우터의 성능을 향상시키도록 하는 스텝모우터 회전축 지지장치에 관한 것으로, 이는 회전축(140)의 일측단에 중심축선상으로 설치홈(141)을 구비하여 이의 설치홈(141)내에 회전축(140)과 동일축선상으로 힘을 작용할 수 있는 코일형의 백스프링(170)을 구비하고, 상기 백스프링(170)의 탄성력에 의해 지지되는 가이드불(160)을 브라켓트(110)의 안착홈(111)에 지지되도록 구성하여서 된 것이다.The present invention improves the centering of the motor and the rotor through the modification of the back spring portion of the precision small stepmotor, and improves the assembling property, The present invention relates to a step motor rotating shaft supporting apparatus which improves the performance of a motor by compensating for disadvantages such as an installation error, Shaped back spring 170 capable of exerting a force in the same axial direction as the rotation shaft 140 in the mounting groove 141. The guide spring 160 is supported by a guide spring 160 supported by the elastic force of the back spring 170, (160) is supported by the seating groove (111) of the bracket (110).

Claims (1)

스텝모우터의 일측에 백스프링을 구비하여 회전축에 작용하는 예압(P)에 대항한 반력(F)을 가지도록 하는 것에 있어서, 상기 회전축(140)의 일측단에 중심축선상으로 설치홈(141)를 구비하여 이의 설치홈(141)내에 회전축(140)과 동일축선상으로 힘을 작용할 수 있는 코일형의 백스프링(170)을 구비하고, 상기 백스프링(170)의 탄성력에 의해 지지되는 가이드볼(160)을 브라켓트(110)의 안착홈(111)에 지지되도록 구성하여서 된 것을 특징으로 하는 스텝모우터의 회전축 지지장지.Wherein a step spring is provided at one side of the step motor so as to have a reaction force F against a preload P acting on the rotary shaft, Shaped back spring 170 capable of exerting a force in the same axial direction as that of the rotary shaft 140 in the mounting groove 141. The back spring 170 is supported by an elastic force of the back spring 170, And the ball 160 is configured to be supported by the seating groove 111 of the bracket 110.
