Analysis of process parameters during press quenching of bevel gear parts
2012 (English)In: The 5th International Swedish Production Symposium: 6th-8th of November 2012 Linköping, Sweden / [ed] Mats Björkman, 2012, 251-259 p.Conference paper (Refereed)
Defining manufacturing tolerances is an important task for a process planner before starting production of a new product or introducing new processes. One of the more complex processes to handle is the heat treatment of gears. Press quenching is a heat treatment method where the gear is mechanically forced to keep or attain the desired geometry, with less geometrical distortions in comparison to oil bath quenching. The objective of this paper is to discover how design of experiments can be used to scrutinize press quenching of bevel gears. The first part of this investigation shows how different process parameter settings influence geometry of the bevel gear. Based on the results of the experiments, predictions and statistical simulations, the outcome of the press quenching process can be estimated. Estimations for the number of defect parts then form the basis for evaluating whether the proposed tolerances meet the quality requirements. The work is based on an industrial case where 55 bevel gear crown wheels for heavy trucks are carburized and then case hardened in a Gleason press quenching machine.
