METHOD AND APPARATUS FOR BACKING THE INSIDE TEETH OF A SLIDING SLEEVE PRODUCED BY WAY OF POWDER METALLURGY FOR A MANUAL TRANSMISSION

摘要

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).
