Patent number: 11976251Abstract: 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.Type: GrantFiled: November 19, 2020Date of Patent: May 7, 2024Assignee: EXXONMOBIL TECHNOLOGY AND ENGINEERING COMPANYInventors: Gary Christensen, David A. Racke, Mark Sitko
