본 발명은 시동모터용 샤프트의 제조방법 및 그에 의해 제조된 샤프트에 관한 것으로, 더욱 상세하게 설명하면, 차량의 시동모터에 사용되는 샤프트를 제조하되, 금속 환봉을 포밍기를 이용하여 다단으로 단차진 샤프트의 형태로 제작한 다음, 샤프트의 중앙부에 전조기를 통해 기어부를 형성시킨 후 열처리함으로써 제작공정이 단순화되어 생산성이 향상되고, 제작된 샤프트의 강도가 증대되는 시동모터용 샤프트의 제조방법 및 그에 의해 제조된 샤프트에 관한 것이다.The present invention relates to a method for manufacturing a shaft for a starting motor and a shaft manufactured by the present invention, which will be described in more detail, wherein a shaft used for a starting motor of a vehicle is manufactured, and a metal round bar is formed in multiple stages using a forming machine. After manufacturing in the form of, then by forming a gear portion through a rolling machine in the center of the shaft and heat treatment, the manufacturing process is simplified to improve the productivity, the manufacturing method of the shaft for the starting motor to increase the strength of the manufactured shaft and thereby To a manufactured shaft.

일반적으로 샤프트라 함은 구동축을 뜻하는 것으로, 특히 차량의 시동모터에 사용되는 샤프트에는 드라이브 샤프트와 아마추어 샤프트가 각각 구비되어 있어서 아마추어 샤프트의 회전력을 전달받은 드라이브 샤프트가 구동력을 발생시켜 차량 의 시동 휠을 구동시키도록 하는 것이다.In general, the shaft refers to a drive shaft. In particular, the shaft used for the starting motor of the vehicle is provided with a drive shaft and an armature shaft, respectively, so that the drive shaft that receives the rotational force of the armature shaft generates a driving force and generates the driving wheel of the vehicle. To drive it.

상기와 같은 샤프트는 그 형태가 차종에 따라 대동소이한 형태로 구성되되, 단차진 환봉의 중앙으로는 기어부가 형성되어 있으며, 끝단으로는 플랜지가 형성된 형태가 대부분인바, 종래의 샤프트의 제조방법을 살펴보면, 우선 환봉을 절삭가공하여 다단으로 단차진 형태로 제작한 다음, 환봉의 중앙부에 기어부를 절삭가공을 통해 형성시키며, 환봉의 일측단에 원판형태의 플랜지를 용접을 통해 고정시키고 열처리를 함으로써 제작을 완료하였다.Shaft as described above is composed of the same shape according to the type of vehicle, the gear part is formed in the center of the stepped round bar, most of the flange is formed in the end bar, the conventional manufacturing method of the shaft Looking at it, first, the round bar is cut and manufactured in multi-stepped form, and then the gear part is formed at the center of the round bar by cutting, and a disk-shaped flange is fixed to one side of the round bar by welding and heat treated. Completed.

상기와 같은 방법으로 제작된 종래의 샤프트는 환봉을 절삭가공을 통해 단차진 형태의 환봉으로 제작함으로써 제작속도가 현저히 떨어질 뿐만 아니라 절삭으로 버려지는 소재가 많아 제작비용을 상승시키는 요인으로 작용하였으며, 또한, 기어 부분도 절삭가공함에 따라 제작시간이 더욱 오래 소요될 뿐만 아니라 금속의 흐름이 끊기게 되어 샤프트의 강도가 현저히 낮아져 마모 혹은 파손이 잦은 문제점을 내포하고 있었다.The conventional shaft produced by the above method is not only the manufacturing speed is significantly reduced by cutting the round bar into a round bar of stepped shape through cutting, but also increases the production cost due to the large amount of material discarded by cutting. In addition, as the gear part is also cut, it takes longer to manufacture and the flow of metal is interrupted, which significantly lowers the strength of the shaft, causing frequent wear or breakage.

To form a gear part, and then heat treatment using a high frequency heat treatment machine, and by grinding the outer diameter, to increase the production speed of the shaft to improve productivity, and significantly reduce the waste of material due to cutting to reduce the manufacturing cost It is done.

또한, 종래의 절삭이나 용접으로 인한 금속의 흐름에 단절이나 변형 및 손상을 불식시켜 샤프트 전체의 강도를 증대시키며, 이로 인해 파손이나 고장 없이 장기간 사용할 수 있도록 함을 또 다른 목적으로 한다.In addition, it is another object to increase the strength of the entire shaft by eliminating breakage, deformation and damage to the flow of metal due to the conventional cutting or welding, thereby enabling long-term use without damage or failure.
