Patent number: 11365810Abstract: A bearing isolator capable of operating under flooded conditions is disclosed. The bearing isolator can include a stator, a rotor, a unitizing element and a sealing element, the stator and rotor form a cavity in which the unitizing element is disposed, and features of the unitizing element with features of the stator and rotor to ensure the stator and rotor stay together while still maintaining a gap between the two components to avoid metal on metal contact. The sealing element resides against a surface of the stator and includes a radially-inward extending lip seal that rides against a running surface of the rotor for improved sealing.Type: GrantFiled: June 24, 2020Date of Patent: June 21, 2022Assignee: Garlock Sealing Technologies, LLCInventors: Christopher Tones, Christopher Fink

Patent number: 10753478Abstract: A bearing isolator having a simple design and made from low-cost materials but which performs comparably to other higher-cost bearing isolators is described. The bearing isolator generally includes a rotor having a snap fit feature protruding from a radially-oriented flange and a stator having a snap fit feature recess for receiving the snap fit feature to thereby join together the stator and rotor without need for, e.g., a separate unitizing element. Furthermore, the rotor and/or stator can be made from lost cost material, such as a nylon/moly material. In some embodiments, the stator further includes a lip seal biased against the radially-oriented flange of the rotor, which, when combined with the labyrinth passage formed at least in part by the snap fit feature and snap fit feature recess, helps to prevent egress and ingress of lubricant and/or contaminates.Type: GrantFiled: November 7, 2017Date of Patent: August 25, 2020Assignee: Garlock Sealing Technologies, LLCInventors: Christopher Tones, Christopher Fink

Patent number: 9987577Abstract: A kammprofile gasket is provided. The kammprofile gasket forms a flow aperture into which an object, such as a strainer or orifice plate, may be machined into the gasket to provide additional functionality. The gasket has a core material with a sealing material overlaying a portion of the core material such that a seal is formed between opposing flanged surfaces. The core material may be machined such that a base plate for an orifice or a plurality of support beams extend into the flow aperture. The plurality of support beams may provide support for a filter or strainer coupled upstream to the core material. The base plate may provide an inclined surface, such as a cone, to an orifice where the cone functions to direct excess flow away from the orifice to self flush.Type: GrantFiled: September 4, 2013Date of Patent: June 5, 2018Assignee: Garlock Sealing Technologies, LLCInventors: Chad Yoder, Matthew Tones, Christopher Tones

Patent number: 7900933Abstract: A seal is disclosed for use on the tapered section of a roll neck in a rolling mill. The seal comprises a flexible circular seal body having a central axis and at least one radially outwardly extending flange joined by a hinge to an angularly extending lip. The hinge has a reduced thickness as compared to the thicknesses of the flange and the lip, and the lip has converging first and second sides leading to an enlarged rim. The rim has first and second peripheral faces that converge to an outer edge contained in a reference plane parallel to the central axis of the seal body.Type: GrantFiled: November 19, 2008Date of Patent: March 8, 2011Assignee: Siemens Industry, Inc.Inventors: Christopher Tones, Peter N. Osgood

Patent number: 7604239Abstract: An assembly for sealing a rotating shaft and a bearing housing which has a stator, a rotor, and a unitizing element. The stator has at least two portions and an annular engagement flange extending in an axial direction having a groove on a radial side thereof. The rotor has at least two portions and an annular engagement flange extending in an axial direction having a groove on the radial side thereof. The annular unitizing element has at least two portions, a stator engaging member that engages the stator groove, a rotor engaging member that engages the rotor groove, and a rear member having a side edge that engages the stator. A radially outer surface of the unitizing element has two areas of differing diameter, one corresponding to the rotor engaging member and the other corresponding to the rear member.Type: GrantFiled: June 19, 2007Date of Patent: October 20, 2009Assignee: Garlock Scaling Technologies LLCInventors: Elizabeth Chitren, Christopher Tones
