摘要： This disclosure relates to a method for controlling lubrication of a rotary shaft seal. The method involves providing an apparatus having a bulk lubricating oil reservoir, a rotary shaft that passes through the bulk lubricating oil reservoir, and a rotary shaft seal. The rotary shaft seal has a sealing edge in proximity with the rotary shaft creating a contact zone. The contact zone has a film of lubricating oil. The method also involves increasing the rate of heat flow along the rotary shaft to reduce temperature of the film of lubricating oil in the contact zone. Increasing the rate of heat flow along the rotary shaft is accomplished by using rotary shaft materials of construction having sufficient high thermal conductivity, rotary shaft coatings having sufficient high thermal conductivities, or increasing the surface area of the rotary shaft. This disclosure also relates to a method for controlling heat transfer in a contact zone, and a method for improving performance of an apparatus.

摘要： A flexure bearing includes an inner race, an outer race, and a plurality of substantially planar radially extending blades coupled between the inner and outer race. The blades have a thickness that is thinner than a thickness of the inner and outer races. The inner race, outer race, and blades have substantially the same height. At least one heating element is coupled to the inner race and/or the outer race. The heating element is configured to apply heat to the race that it is coupled to in order to tune the flexure bearing.

摘要： There is provided a sliding member that has sufficient wear resistance and good adhesion to a base formed of a sintered body. The sliding member includes a surface layer formed of a crosslinked fluoropolymer and a base that adheres closely to the surface layer. The base is a sintered body having a full density ratio in the range of 0.75 to 0.96 and is formed of a material having higher thermal conductivity than a fluoropolymer. The surface layer has a thickness in the range of 1 to 300 μm.
