What is tilt pad bearing?
Tilting pad thrust bearings are designed to transfer high axial loads from rotating shafts with minimum power loss, while simplifying installation and maintenance. Each bearing consists of a series of pads supported in a carrier ring; each pad is free to tilt so that it creates a self-sustaining hydrodynamic film.
How do tilt pad bearings work?
Each bearing consists of a series of pads supported in a carrier ring (retainer). Each pad is free to tilt, resulting in a self-forming hydrodynamic film. The self-equalizing design balances the load between the pads and accommodates misalignment or deflection between the bearing and collar.
What is a tilted pad thrust bearing?
Definition. Tilting-pad thrust bearings (TPTB) are mechanical systems used mainly in heavy-duty rotating machinery to locate rotors and support axial loads. They are characterized by their greater load-carrying capacity compared with fixed-geometry thrust bearings (FGTB).
What is a Kingsbury bearing?
Kingsbury is most famous for his hydrodynamic thrust bearing which uses a thin film of oil to support weights of up to 220 tons. This bearing extended the service life of many types of machinery during the early 20th century. It was primarily outfitted on Navy ships during World War I and World War II.
What is Michell thrust bearing?
Thrust bearings were independently invented by Australian engineer George Michell (pronounced Mitchell) who patented his invention in 1905. These create wedge-shaped regions of oil inside the bearing between the pads and a rotating disk, which support the applied thrust and eliminate metal-on-metal contact.
What is the main purpose of the Kingsbury thrust?
Shoe Support The spherical pivot on Kingsbury thrust shoes allows the shoe to tilt not only in the direction of rotation but also in the radial direction, compensating for some misalignment between the thrust bearing face and the rotating thrust collar.
