一、开发的概念 汽车传动装置用的行星支座,传统的制造方法是用造型铸造成毛坯后经金加工而成。 而今,在国外是采用粉末成形烧结技术,不用金加工的方法来制造,工艺简单,零件质量好,强度高。 这种行星支座(见图)是个台阶差别很大的零件,因此,采用粉末金属成形技术,以及在烧结同时使用添加焊剂(料)的方法,来寻求四轮驱动车用行星支座的高机能和低成本。
First, the concept of development Planetary bearings used in automotive transmission, the traditional method of manufacturing is cast into a rough cast by the metal. Now, in foreign countries is the use of powder sintering technology, not the method of manufacturing gold, simple process, parts of good quality and high strength. This planet carrier (see photo) is a very different part of the step, so the use of powder metal forming techniques, and sintering at the same time using the flux (material) method to find the four-wheel drive planetary carrier high Function and low cost.
