On the Bearing Performance of Cu-Pb alloys (Kelmet)

Tadao Satô, Toshio Saitô and Kazuo Ôyama


Abstract:

The material and the bearing performance of Cu-Pb alloys (Kelmet) were studied and the following results have been obtained. For Diesel engines mounted on motor cars, Kelmet of Copper dendritic structure has been often used. In the present experiment, the alloys of lead granular structure were tested. The former is generally hard with B. H. N. 35∼40, while the latter is soft with B.H.N.28∼32.8. Casting and lining operation of these alloys were comparatively easy, and large bearing were manufactured without great difficulty in casting. In this experiment Kelmet showed adequate ability of lubrication, antifriction and endurance under the present practice of lubrication as half-bearing used on the axle boxes of cars. So, Cu-Pb alloy may be substituted for white metal (WJ 6,7,8 and 9) from the sandpoint of saving tin consumption and on account of its excellent endurance.
