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).
Claims2
A method for backing inside teeth of a sliding sleeve produced by way of powder metallurgy for a manual transmission, wherein backings of the teeth forming front-side pitches are formed with a rolling tool by back-rolling accompanied by plastic displacement of material from a backing region, wherein front-side tooth sections delimited by the backings are at the same time calibrated whilst forming and/or calibrating the front side pitches with the rolling tool for forming the backings.
