Studies in hydronamic thrust bearings III. The parallel surface bearing

Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1975
Abstract The parallel surface bearing is interesting in that on first sight it completely contradicts the classical Reynolds lubrication theory. Secondly its mode of operation has only recently been capable of detailed explanation. The optical technique, described in the last section offered a precise method of proving that thermal ...

Bearing Surfaces for Total Hip Arthroplasty

Journal of the American Academy of Orthopaedic Surgeons, 2018
Metal-on–highly cross-linked polyethylene is considered the preferred bearing surface for conventional total hip arthroplasty because of its safety profile and excellent results in the first 10 to 15 years of use. However, with younger patient age, activity expectations increase, and the life expectancy of patients with total hip arthroplasty also has ...

(iii) Bearing surfaces

Orthopaedics and Trauma, 2013
Abstract Alternative bearings surfaces to polyethylene have reduced wear and have led to improved patient outcomes, allowing younger and more active patients to be considered for joint replacements. These bearing surfaces have been developed largely as a response to osteolysis and loosening associated with polyethylene particulate debris.

The Biomechanical Problems of Polyethylene as a Bearing Surface

Clinical Orthopaedics and Related Research, 1990
The metal backings of acetabular components can reduce the available polyethylene thickness, often to an alarming extent. This study indicated that the pitting and cracking of thin polyethylene surfaces have some similarities to tibial and patellar bearings and that creep-related deformation occurred more frequently in thin polyethylene components ...

Bearing Surface Contact

2016
Tribology is the science and engineering of interacting surfaces in relative motion. Solid surfaces (more specifically, interface of solid/gas or solid/liquid) have complex structures and features.

Alternative Bearing Surfaces

2006
The articulating joints of hip prostheses generate wear debris, and accumulation of wear particles in the local tissues can result in osteolysis, which may ultimately require replacement of the prosthesis. The purpose of new hip bearing materials is to extend implant life by substantially decreasing the amount of wear debris generated thus greatly ...

Polyethylene as a Bearing Surface

2000
Ultra-high molecular-weight polyethylene (UHM-WPE) is the most commonly used bearing material in total joint replacement. Wear of UHMWPE is a serious clinical problem that limits the longevity of orthopaedic implants. Excessive wear may lead to gross mechanical failure such as fracture and disas-sociation [3] and the release of particulate wear debris ...

Inspection of Bearing Surfaces

Aircraft Engineering and Aerospace Technology, 1942
WHEN man invented the wheel, bearings were introduced into civilization and every machine since devised incorporates, in some form, means of sustaining a loaded member in motion by another fixed member. It is not surprising, therefore, that examination of bearings forms a high proportion of all engineering inspection and the phrase “to look at the ...

Parallel Surface Thrust Bearing

A S L E Transactions, 1958
The theory for the thermal wedge thrust pad is given assuming (a) all the heat is taken away by the oil and (b) the viscosity is constant across the thickness of the film. The viscosity is allowed to vary in the direction of motion. Solutions are obtained by both analytical and relaxation methods for infinite and finite pads.
