Powder Metal Technology Tested for Production of Transmission Gears
01 Jun 2005
Hoganas AB has been cooperating with Scania, a leading manufacturer of heavy trucks, to test the potential of various powder metal (P/M) manufacturing routes for high-performance gears. The tests on a gear for a heavy truck show how far P/M technology has come.
The latest research in this area is presented in a paper, "Highperformance Gears", by Sven Bengtsson and Linnea Forden of Hoganas AB and Magnus Bergstrom of Scania. The paper compares the performance of gears produced by three different P/M manufacturing routes - cold compaction, warm compaction and surface densification.
Tests were carried out on a 20tooth, 700-gramme planetary gear used in the hub reduction unit of Scania heavy trucks. D.AB and Astaloy 85Mo were used as base materials for the P/M prototype gears, which were tested at the Scania Technical Centre in Sodertalje, Sweden.
Warm compaction and surface densification are two performanceenhancing processes that are helping to push P/M technology towards the high strength and fatigue properties required for transmission gears.
