Abstract
The friction and wear characteristics of hydraulic guide vane bearing, which was designed to be worthy to sever operation, were investigated with lead-free self-lubrication bearing using radial journal test apparatus in fresh water condition. The friction and wear behaviors were compared with that of conventional self-lubrication. Though the friction coefficient of lead-free self-lubrication bearing is slightly high tendency in the early tests, ratio of abrasion quantity is not influenced by surface state of bearing and shaft. Lead-free self-lubrication bearing influenced by Hardness of shaft, and
ratio of abrasion quantity of lead-free self-lubrication bearing is less than that of conventional self-lubrication. Lead-free
self-lubrication bearing is applicable to hydraulic guide vane bearing.
