Description
본 발명은 차량 등에 설치되어 전력을 제공하는 발전기로터의 중심부에 압입되어 설치되는 축을 제조함에 있어서, 이 축의 강도와 경도를 향상시키고 제조공정을 줄이면서 용이하게 제조할 수 있도록 한 발전기축의 제조방법에 관한 것이다.The present invention provides a method of manufacturing a generator shaft that can be easily manufactured while improving the strength and hardness of the shaft and reducing the manufacturing process in manufacturing a shaft that is pressed into the center of the generator rotor for providing electric power installed in a vehicle, etc. It is about.
일반적으로 차량용 발전기에 설치되는 축(1)은 도 2에서와 같이 중앙에 폴압입부(2)를 형성하고 이의 양측에는 베어링 조립부(3)(4)를 형성하고 양단에 슬립링 압입부(5)와 체결부(6)를 형성하도록 구성되어 있었다.In general, the shaft (1) installed in the vehicle generator forms a pole indentation (2) in the center as shown in Figure 2 and the bearing assembly (3) (4) formed on both sides thereof and slip ring indentation ( 5) and the fastening part 6 were comprised.
상기와 같은 구조를 갖는 축을 제조하는 종래의 방법은, 환봉으로 된 소재를 가공부에 공급하고 이의 양센터와 길이를 가공한 다음, 이의 폴압입부와 베어링조립부 및 체결부를 1차로 선삭가공 하며 이 1차선삭된 소재를 슬립링 압입부가 형성되도록 하면서 상기 1차선삭된 부분을 재가공하는 2차선삭가공을 하고 이 2차선삭가공후 상기 각부를 3차에 걸친 전조공정에서 전조하여 축의 형상을 가공하며 이 상태에서 슬롯홈의 가공, 베어링 조립부의 연마공정을 거쳐 상기 축의 제조를 완료하도록 되어 있었다.In the conventional method of manufacturing a shaft having the structure as described above, the raw material of the round bar is supplied to the processing part, and the center and the length thereof are machined, and then the pole press part, the bearing assembly part, and the fastening part thereof are first turned. The primary-turned material is subjected to secondary turning processing to rework the first-turned portion while the slip ring press-fitting portion is formed, and after the second-turning processing, the respective parts are rolled in three rolling processes to form the shape of the shaft. In this state, the slot groove was processed and the bearing assembly was polished to complete the manufacturing of the shaft.
그러나, 상기와 같은 종래의 것은 축의 제조공정이 많아 축의 제조가 난해하게 되었고 또, 축의 가공상태가 일률적으로 이루어지지 못하여 불량품 발생률이 높게 되는 폐단이 있었으며, 상기 많은 공정에 의하여 제조공수가 많이 들게 되었고 상기 공정에 있어서, 플랜지부와 슬립링 압입부를 단조하는 공정이 매우 번거롭게 되는 등의 문제점이 있었다.However, such a conventional one has a lot of manufacturing process of the shaft, the manufacturing of the shaft is difficult, and the processing state of the shaft is not uniformly made, there is a closed end of the high occurrence rate of defective products. In the process, there has been a problem that the process of forging the flange portion and the slip ring press-fit portion becomes very cumbersome.
본 발명은 상기와 같은 종래의 제반 문제점을 감안하여 안출한 것으로 발전기에 설치되는 축을 제조함에 있어서, 축의 플랜지부와 슬립링 압입부를 단조하는 단조공정을 간단히 하고 상기 단조공정에 의하여 상기 축의 완성도와 정밀도를 향상시키면서 제조공수를 크게 절감시킬 수 있도록 구성한 것인바, 이를 이하에서 첨부한 도면과 실시예에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned conventional problems, and in manufacturing a shaft installed in a generator, the forging process for forging a flange portion and a slip ring press-fitting portion of the shaft is simplified, and the completeness and precision of the shaft by the forging process. It will be configured to greatly reduce the manufacturing labor while improving the bar, which will be described in detail based on the accompanying drawings and examples below.

실시예Example
발전기의 축을 제조함에 있어서, 단조소재를 가공부에 공급하고 센터와 길이를 가공한 다음, 단조부위인 플랜지부와 슬립링 압입부를 형상단조로 가공하고 상기 플랜지부의 폭과 외경을 크게 형성하여 경도를 향상시키도록 하며 상기 단조를 한 번의 공정으로하여 단조상태에서 외경을 결정하고 상기 축을 제조하도록 구성한 것이다.In manufacturing the shaft of the generator, the forging material is supplied to the processing part, the center and the length are processed, and the flange part and the slip ring press-in part are forged into the forging part, and the width and the outer diameter of the flange part are made large so that the hardness is increased. The forging is performed in one process to determine the outer diameter in the forging state and to manufacture the shaft.
이상과 같이하여 단조시키는 본 발명의 축은 상기 단조후 폴압입부(2)와 체결부(6)를 전조가공하고 이를 탈연마공정에서 탈연마하며 상기 가공이 완료된 축의 선단에 슬롯홈을 가공하여 상기 축을 완성하도록 한 것으로 상기 단조공정의 형상단조로써 가공되는 슬립링 압입부와 플랜지부의 경도를 향상시킬 수 있게 되는 것이다.The shaft of the present invention forging as described above is forging the pole indentation part 2 and the fastening part 6 after the forging and de-polishing it in the de-polishing process and by processing the slot groove at the end of the shaft is completed By completing the shaft, it is possible to improve the hardness of the slip ring indentation and the flange to be processed by the shape forging of the forging process.
이상과 같은 본 발명은 상기와 같이 형상단조의 공정을 거쳐 축을 제조하도록 하므로써 축의 제조공정을 크게 줄일 수 있고 또, 이에따른 제조공수를 줄이면서 생산성을 향상시킬 수 있으며 상기 축의 정밀도와 완성도를 향상시켜 불량품 발생률을 크게 저감시킬 수 있게 되는 등의 특징을 지닌 것이다.As described above, the present invention can reduce the manufacturing process of the shaft by reducing the manufacturing process of the shaft by manufacturing the shaft through the forging process as described above, thereby improving productivity while improving the precision and completeness of the shaft. It is possible to greatly reduce the rate of defective products.
