Title Influence of gear modification on noise emissions by gear pumps
Original title Einfluss der Zahnkopfrücknahme auf die Geräuschemissionen beim Betrieb von Aussenzahnradpumpen [in German]
Bibliographic information 1990, Vol.96, No.38, p.262-264, 266, 268. Illus. 8 ref.
Abstract The noise of gear pumps is mainly caused by interaction of the gear wheels. The benefits of tooth modification on noise emission were theoretically investigated. Noise measurements were carried out on three pumps with different designs. The pump with teeth shortened by 10µm was found to emit less noise than the other two pumps with either polished or abraded full-length teeth.
