Tilting Pad Thrust Bearing Calculation Method for Steady-State Hydrodynamic Design, Part 1
Tilting Pad Thrust Bearing Calculation Method for Steady-State Hydrodynamic Design, Part 1
This calculation method guides the design of oil-lubricated hydrodynamic plain thrust bearings with tilting pads. A lubricant film fully separates the thrust collar from the bearing surfaces, and a wedge-shaped clearance gap forms on its own during operation. The pad width-to-length ratio can be varied between 0,5 and 2.
The method also covers other gap shapes, such as parabolic clearances, and other slider types, such as circular blocks, provided numerical solutions of Reynolds' equation exist. It assumes steady operation with constant load and speed on all rotating parts, and it does not apply to heavily loaded designs. Intended for ventilation fans, geared drives, pumps, turbines, electric motors, compressors and machine tools.
