PURPOSE:To reduce time required for the process and to save energy by forming the shaft and flange separately and by treating them by cementation at a specific temperature after brazing them with each other in a body. CONSTITUTION:The shaft 7 of the stator shaft 4 is made of a pipe, the flange 8 is formed by forging, the shaft 7 is put into the hole of the flange 8 and brazed with each other in a body. Next, it is cooled in the furnace down to a temperature slightly lower than the melting point of the solder 12, a cementation gas is injected into the furnace and the cementation treatment is performed to form the stator shaft. In this way, the stator shaft can be manufactred in a short time as compared with a process, in which the stator shaft is formed in a body from the beginning, to save energy. |
