具有局部选择的表面致密的被烧结的啮合式元件
摘要：
用于制造至少部分被表面致密的金属的啮合式元件的方法，该啮合式元件包括被致密的烧结材料，以便改善强度变化曲线，其中制造出啮合式元件的毛坯，该毛坯相对于啮合式元件的最终尺寸具有局部选择的加工余量(701)并且借助于至少一个滚轧刀具被滚轧到最终尺寸，其中至少在啮合式元件的一个齿的至少一个齿面(705；706)和/或齿根(704)的区域中局部变化地对啮合式元件进行致密加工以产生致密的表层。
摘要（英）：

Disclosed is a method for producing an at least partly surface-compressed metallic gear element that comprises a compressed sintered material in order to improve a strength curve. A blank of the gear element is produced with a locally selective oversize (701) relative to a final size of the gear element and is rolled by means of at least one rolling tool so as to obtain the final size. The gear element is compressed in a locally varied manner at least in the area of at least one flank (705; 706) and/or one root (704) of a tooth of the gear element in order to create a compressed surface layer.
