用于制造烧结齿轮的方法和烧结齿轮
摘要：
本发明涉及一种用于制造烧结齿轮(1)的方法，所述烧结齿轮具有齿轮体(2)，所述齿轮体沿轴向方向(3)由第一轴向端面(4)和第二轴向端面(5)限定，所述烧结齿轮还具有至少一个用于至少一个缠绕式传动机构的轨道(8、10、12)，所述轨道设置在径向周面(7)上，所述周面在第一轴向端面(4)和第二轴向端面(5)之间延伸，其中，齿轮体(3)由烧结材料按粉末冶金的方法制造，所述方法包括将粉末压制成坯料的步骤和烧结坯料的步骤，在压制期间在第二轴向端面(5)上或中构成用于设置密封元件(15)的密封面(14)，并且在烧结之后至少在密封面(14)的区域内对齿轮体(3)进行氧化处理。
摘要（英）：

The invention relates to a method for making a sintered gear (1). The sintered gear has a gear body (2) which is defined by a first axial end face (4) and a second axial end face (5) in the axial direction (3). The sintered gear also has at least one rails (8, 10, 12) used for at least one winding type transmission mechanism, the rails being arranged on a radial circumferential surface (7). The circumferential surface extends between the first axial end face (4) and the second axial end face (5). The sintered body (3) is made from sintering materials according to a powder metallurgy method which comprises a step of pressing powder into blanks and a step of sintering the blanks; during pressing, a sealing surface (14) used for arranging a sealing element (15) is formed on or in the second axial end face (5) and the gear body (3) is oxidized at least in the area of the sealing surface (14) after sintering.
