Title:
粉末冶金で製造される変速機用滑りスリーブの内歯の製造方法
Document Type and Number:
Japanese Patent JP5360624
Kind Code:
B2
Abstract:
A method for backing the inside teeth (2) of a sliding sleeve (3) produced by way of powder metallurgy for a manual transmission is described where the backings (1) of the teeth (4) forming the front-side pitches (9) are formed with the aid of a rolling tool (5) by back rolling accompanied by plastic deformation of material from the backing region. In order to prevent burr formation, it is proposed that the front-side tooth sections (8) delimited by the backings (1) are simultaneously calibrated whilst forming and/or calibrating the relevant pitches (9) with the aid of the rolling tool (5) for forming the backings (1).
