This document specifies a calculation method for oil-lubricated hydrodynamic plain bearings with complete separation of the thrust collar and tilting pad thrust bearing surfaces by a film of lubricant.<\/p>\n

This document applies to plain thrust bearings with tilting-type sliding blocks (tilting pads), where a wedge-shaped lubrication clearance gap is automatically formed during operation. The ratio of width to length of one pad can be varied in the range B\/L<\/i> = 0,5 to 2.<\/p>\n

This document is not applicable to heavily loaded tilting pad thrust bearings.<\/p>\n

\n
\n NOTE\n <\/div>\n

Equivalent calculation procedures exist that enable operating conditions to be estimated and checked against acceptable conditions. The use of them is equally admissible.<\/p>\n<\/div>\n
