Publication number: 20090211681Abstract: A tire rim for a non-pneumatic tire. The tire rim has an outer hoop that slideably engages a mounting ring disposed on the non-pneumatic tire. The mounting ring is slideably engaged in a lateral direction on the outer hoop. The rim and mounting ring can be secured using one or more mounting plates. The rim allows for the non-pneumatic tire to be easily mounted and removed.Type: ApplicationFiled: February 25, 2008Publication date: August 27, 2009Inventors: Richard L.

Publication number: 20090110894Abstract: Polyurethane elastomer articles formed from prepolymer mixtures having free diphenylmethane diisocyanate (MDI) content from 2.0 to 5.0 wt %, based on the weight of the prepolymer mixture. The prepolymer mixtures comprise a polyester, polyether, or polycaprolactone (PCL) prepolymer and MDI. The polyurethane elastomer articles are formed by curing the prepolymer mixture with a chain extender, such as a curative comprising a methylenedianiline-sodium chloride complex. The articles have good physical properties that may weigh over 225 kg, and have a three-axis thickness greater than 10.2 cm.Type: ApplicationFiled: September 8, 2008Publication date: April 30, 2009Inventors: George H. Nybakken, Richard L. Palinkas, Ian Laskowitz, Thomas H. Peter

Patent number: 5605657Abstract: An industrial solid tire for heavy-load, off-road use having a cast polyurethane tire thereon is produced by a batch method. The tire is a heat cured polyurethane produced from a dispersion of a prepolymer, a curative and an amount of a silicone dispersing and lubricant agent. The amount of silicone is between 1.0 and 4.0 parts per hundred of the prepolymer. A method for manufacturing the tire is included.Type: GrantFiled: July 1, 1993Date of Patent: February 25, 1997Assignee: Uniroyal Chemical Company, Inc.Inventors: George H. Nybakken, Richard L. Palinkas, David M. Clonch

Patent number: 5107913Abstract: A wheel for a relatively slow vehicle used in industrial applications and incorporating a solid tire formed of dense elastomer material such as cast polyurethane, having a relatively large radial depth, for example six inches, a relatively large width, for example twelve inches, and a deep slot extending circumferentially around the tire and dividing the tire into sections separated by the slot with the ratio of the depth of the slot to the lateral width of each section being in the range of 0.65 to 1.75. The tire is bonded to the wheel rim and includes sidewalls containing concave surfaces terminating in relatively thin lips bonded to the outer edges of the rim, keeping stress in the edge of the tire relatively low which helps reduce tire failures from beginning in the edges of the tire along the rim edges.Type: GrantFiled: March 28, 1991Date of Patent: April 28, 1992Assignee: Simmons-Rand CompanyInventors: David M. Clonch, George H. Nybakken, Richard L. Palinkas

Patent number: 5023040Abstract: A non-pneumatic tire is disclosed having a polyether polyol urethane elastomeric body with a plurality of angular radial ribs interconnected by webbing. The urethane is formed of at least two isocyanate-end capped polyether polyols of differing molecular weights to yield a tire with improved highway life and good vehicle ride characteristics.Type: GrantFiled: May 25, 1990Date of Patent: June 11, 1991Assignee: Uniroyal Chemical Company, Inc.Inventors: Vincent J. Gajewski, Wallace I. Goddard, Richard L. Palinkas, George H. Nybakken

Patent number: 4784201Abstract: A non-pneumatic tire with an annular body of resilient elastomeric material and an outer cylindrical member supported by circumferentially spaced-apart ribs, is provided with four vibration-reducing features. First, the tire has an outer tread surface with a crown radius. Secondly, the tread has a pattern with a plurality of circumferential grooves and lateral grooves arranged to reduce uneven contact pressures caused by radial forces carried by the tire's ribs. Thirdly, the spacing of the ribs is randomly varied around the circumference of the tire to broaden a vibration spectrum caused by the ribs and reduce peak vibrations. Fourthly, a wheel rim that supports the annular body is provided with a structurally incorporated hoop to reduce deflection of the wheel rim during tire operation.Type: GrantFiled: May 13, 1986Date of Patent: November 15, 1988Assignee: The Uniroyal Goodrich Tire CompanyInventors: Richard L. Palinkas, Scott R. Pajtas, George H. Nybakken

Patent number: 4273177Abstract: A pneumatic radial tire has a two-ply tread reinforcing breaker wth cords of filamentary material. The breaker plies are of unequal widths and arranged symmetrically with respect to the median circumferential or equatorial plane of the tire, the overall width of the breaker being substantially the width of the overlying tread. In the region of each shoulder of the tread, the edges of one ply are folded back on themselves forming superimposed two-ply regions and three-ply regions enclosing the edges of a narrow, non-folded ply. Surrounding each two-ply region of the folded ply is a cushion rubber which is softer than the tread or breaker skimcoat rubbers. The breaker construction substantially eliminates breaker edge separation, resulting in a more durable radial tire which can be recapped to provide further service.Type: GrantFiled: March 31, 1980Date of Patent: June 16, 1981Assignee: Uniroyal, Inc.Inventor: George H. Nybakken
