Patent number: 6688768Abstract: A dry bearing (102, FIG. 2(f)) for a hinge pin or the like comprises a bush 402 mounted in a radially supportive housing (16), the bush being formed by a circumferentially discontinuous tubular form made by rolling a strip of steel-backed, bearing material having a filled polymer infiltrated sintered bronze (ISB) lining about a mandrel (FIG. 32, 2(c)). The tubular form is, after mounting and to provide a more uniform inside diameter, burnished by pushing therethrough a burnishing tool (50), having a cylindrical portion (51), of larger diameter than the mounted form. The bearing (and method of manufacture) differ from the art in that a minor part of the lining surface is, prior to passage of the burnishing tool and conveniently when still in strip form, compressed in part as depressions (troughs 442) arrayed over the surface.Type: GrantFiled: May 15, 2001Date of Patent: February 10, 2004Assignee: Glacier Garlock Bearings Inc.Inventor: Kenneth Macleod McMeekin

Patent number: 6478468Abstract: A plain bearing comprises a metal backing, a layer of a porous matrix of sintered metal on the backing and a filled PTFE infiltrated into the interstices of the sintered layer and standing proud of the sintered layer, wherein the PTFE is filled with 1-20% by volume fibrillated aramid fibres and 10-30% by volume glass. The glass is preferably E-glass present as milled filaments of length 0.05-0.30 mm and diameter 0.010-0.020 mm and coated with a silene sizing agent. The fibrillated aramid fibres provide reinforcement and improved load bearing capacity and the glass provides an abrasive filler which abrades asperities on a body and creates a smooth polished surface against which to bear, thereby improving its life. The PTFE preferably also includes ferric oxide and carbon black to about 1.5% and 1.2% by volume respectively which both pigment the polymer and act as fine abrasive and lubricant respectively. The carbon black content may be increased to about 10% to provide electrical conductivity.Type: GrantFiled: May 18, 2001Date of Patent: November 12, 2002Assignee: Glacier Garlock Bearings Inc.Inventors: Kenneth Macleod McMeekin, Janette Johnston

Patent number: 6461679Abstract: A bearing material and a method for the production thereof are described. The bearing material comprising a matrix of polytetrafluoroethylene having dispersed therein in volume %: a melt-processable fluoro-polymer in the range from 2 to 10; an inorganic particulate filler material in the range from 10 to 30; and, up to 5 of a ceramic particulate material.Type: GrantFiled: February 5, 2001Date of Patent: October 8, 2002Assignee: Glacier Garlock Bearings, Inc.Inventors: Kenneth MacLeod McMeekin, Johnston Janette

Patent number: 6390682Abstract: A plain bearing comprises a metallic backing, a sintered porous metal layer bonded to the backing and a lining layer infiltrated into the pores of the porous metal layer and overlying the sintered metal layer, said lining layer comprising PTFE containing 10-30% by vol. of particulate wear-resistant filler, 2-10% by vol. fibrillated aramid fibers and 2-10% by vol. of a melt processable fluoropolymer. The melt processable fluoropolymer is a copolymer of the group tetrafluoroethylene-hexafluoropropylene, tetrafluoroethylene-perfluoroalkylvinylether and monofluoroalkoxy. Such a bearing exhibits superior cavitation erosion resistance and may, by increasing the temperature and/or duration of the sintering operation that is normally performed after the mixture of ingredients has been applied to a backing material, be made to exhibit significantly improved fatigue strength.Type: GrantFiled: August 21, 2000Date of Patent: May 21, 2002Assignee: Glacier Garlock Bearings, Inc.Inventors: Kenneth Macleod McMeekin, Janette Johnston

The bearing (and method of manufacture) differ from the art in that a minor part of the lining surface is, prior to passage of the burnishing tool and conveniently when still in strip form, compressed in part as depressions (troughs 442) arrayed over the surface.Type: ApplicationFiled: May 15, 2001Publication date: March 14, 2002Inventor: Kenneth Macleod McMeekin
