Patent number: 11384792Abstract: A slewing bearing includes an inner annular body formed of unhardened stainless steel and coupleable with a fixed member and having an inner race with an unhardened race surface. An outer annular body is disposed about the inner body and is formed of unhardened stainless steel, is coupleable with a rotatable member, and has an outer bearing race with an unhardened race surface and a plurality of gear teeth engageable by a drive pinion to angularly displace the outer body. Rolling elements are disposed between and rotatably couple the inner and outer annular bodies. An annular seal is coupled with the outer annular body and has two opposing axial ends, an axial thickness defined between the ends, a sealing lip engageable with the inner body and an outside diameter and is sized such that the ratio of the outside diameter to the axial thickness is greater than fifty.Type: GrantFiled: August 31, 2020Date of Patent: July 12, 2022Assignees: AKTIEBOLAGET SKF, KAYDON S DE R.L. DE C.V.Inventors: Raymond Lee Chaplin, Reinhard Messner, Joel Eduardo Quintanilla López, Roberto Ricardo Rodriguez, David J VanLangevelde

Patent number: 9897209Abstract: A sleeve, rotary seal, rotary seal assembly, shaft with an integrated primary surface, rotary seal assembly component, and/or any combination thereof which preferably results in rotary seals having a higher tolerance for radial eccentricity (static eccentricity and/or dynamic eccentricity). Related methods of manufacturing, using, and/or providing same are also set forth.Type: GrantFiled: March 26, 2015Date of Patent: February 20, 2018Assignee: AKTIEBOLAGET SKFInventors: Raymond Lee Chaplin, III, Tyler James Ryther

Publication number: 20160377182Abstract: A rotary seal and rotary machine incorporating such a rotary seal. The rotary seal includes a first race defining a plurality of grooves, and a second race defining a plurality of sealing lips. The plurality of sealing lips are disposed in the plurality of grooves such that a compound seal is formed between the first and second races, and the first race and the second race are relatively rotatable.Type: ApplicationFiled: June 24, 2015Publication date: December 29, 2016Applicant: AKTIEBOLAGET SKFInventors: Mark K. Zitting, Daniel Paul Hurst, Raymond Lee Chaplin

Patent number: 9383018Abstract: A cartridge seal for sealing a space between a housing and a rotatable shaft includes a rotary sealing member having an inner surface defining a bore for receiving the shaft and a circular outer flange extending radially outwardly from and circumferentially about a central axis, the outer flange having a radial sealing surface. A static seal assembly is disposed about the rotary member and includes an annular casing coupleable with the housing and an annular static sealing member disposed within the casing and having a radial sealing surface engageable with the rotary member sealing surface to form a sealing interface. A biasing member axially biases at least a portion of the static sealing member toward the rotary member flange. An annular collar is disposed within the casing and axially retains the rotary member within the casing such that the seal assembly is mountable on a shaft as a single unit.Type: GrantFiled: March 15, 2013Date of Patent: July 5, 2016Assignee: AKTIEBOLAGET SKFInventors: Tyler James Ryther, Raymond Lee Chaplin

Patent number: 9360115Abstract: A seal assembly includes an annular static sealing member disposed within an annular channel in a housing or shaft. An annular dynamic sealing member is disposed coaxially within or about the static member and has a circumferential sealing surface engageable with the shaft or housing. An annular biasing member is disposed radially between the static and dynamic sealing members and is configured to bias the dynamic sealing member radially to maintain engagement of the sealing surface and the shaft or housing. The static member is configured to prevent relative angular displacement between the static and biasing members and the dynamic member is configured to prevent relative angular displacement between the dynamic and biasing members. As such, the dynamic sealing member, the biasing member and the static sealing member angularly displace within the channel as a single unit when torque above a particular magnitude is applied to the dynamic sealing member.Type: GrantFiled: October 28, 2013Date of Patent: June 7, 2016Assignee: AKTIEBOLAGET SKFInventors: Raymond Lee Chaplin, Tiberio J. Gonzalez, Tyler James Ryther
