Patent number: 6929402Abstract: An apparatus for rotatably mounting and axially fixing a gear on a shaft comprises a bushing fixed within a bore of the gear. A sleeve is received on and fixed relative to the shaft. The sleeve is surrounded by and journalled for rotation within the bushing. A thrust ring is fixed relative to and projects radially from the shaft on one side of the gear. A retainer on the one side of the gear defines a circular channel within which the annular thrust ring is axially confined.Type: GrantFiled: March 17, 2003Date of Patent: August 16, 2005Assignee: Morgan Construction CompanyInventor: David G. Titus

Patent number: 6880426Abstract: A parking brake for a motor vehicle includes an actuating lever supported rotatably about an axis, a catch element, a pawl element connected to a release device and capable of being brought into engagement with the catch element, a pull cable connected to the actuating lever, two support plates, and a bearing device. The catch element is formed on the actuating lever, and the actuating lever and the pawl element are held between the support plates. In addition, the bearing device is placed between the support plates, the actuating lever being mounted by the bearing device in a manner such that it can rotate about the axis. The bearing device includes steps and is secured between the support plates by the steps in a manner such that the bearing device does not overhang on an outside of said support plates.Type: GrantFiled: July 16, 2002Date of Patent: April 19, 2005Assignee: Edscha AGInventors: Markus Gross, Michael Lorenz, Ulf Braker, Markus Boehm, Markus Feise, Juergen Gropp

Patent number: 6702468Abstract: A sliding bearing is provided for a magnetically driven centrifugal pump with an outer stationary tubular bearing housing within which lie antirotationally mounted bearing bushings and with a rotationally mounted hollow bearing shaft, lying coaxially in the bearing housing to accommodate the pump impeller shaft, having bearing sleeves, lying within the bearing bushings. Contacting the end faces of the bearing bushings on the outer side lie axial bearing rings which are in each case held by an outer axial disc arranged on or alongside the bearing shaft at both ends. The sliding bearing constitutes a preassembled unit, the parts of which are captively mounted to one another. The two axial discs at the end faces are fastened to or alongside the bearing shaft and hold the bearing shaft with its bearings within the bearing housing.Type: GrantFiled: November 28, 2001Date of Patent: March 9, 2004Assignee: ITT Manufacturing Enterprises, Inc.Inventor: Ulrich Rennett

Patent number: 6619758Abstract: There is disclosed herein an improved and simplified wheel and bearing assembly, such as for skates and the like comprising a bearing inner race preferably formed of a plastic material such as polyurethane. A pair of bearing outer races, preferably of a relatively strong material such as titanium, are coupled with outer surfaces of the bearing inner race. Mating surfaces of the bearing inner race and the bearing outer races are configured and are coated with a lubricant to provide bearing surfaces for the wheel.Type: GrantFiled: February 25, 2002Date of Patent: September 16, 2003Inventor: Amara Ross

Publication number: 20030118259Abstract: A bearing assembly having integral molded bearing surfaces. Each bearing surface is molded within its respective inner and outer race. The use of plastic injection molded parts enables high precision with low cost to achieve a reliably rotating caster wheel. The use of integral molded bearing surfaces within the respective races eliminates the problem of having to remove flash from the molding process or concern about indentations made by ejection pins if a separate bearing part were used. The use of a split spanner bushing with the openings of the inner race members permits the bearings to be more easily assembled as well provides greater strength and integrity to the bearing assembly once it is molded into a hub and wheel.Type: ApplicationFiled: September 26, 2002Publication date: June 26, 2003Inventors: Thomas E. Denner, Michael Kidd

Publication number: 20010014189Abstract: A bearing assembly for use with a wheel having an outer circumferential tire portion and an opening formed through a central portion. The bearing assembly includes a male member and a female member, each having a flange portion extending around its circumference at one end thereof and means for securing the members axially together at opposite ends thereof. Bearings are provided upon the male and female members and are sandwiched between the flanges and the wheel. The bearings are of a single piece construction and are formed to provide arcuate surfaces around the periphery of the bearing which provide the contact between the associated parts.Type: ApplicationFiled: December 22, 2000Publication date: August 16, 2001Inventor: Richard C.

Patent number: 6030127Abstract: A guider assembly for a rotary component idles about a given point on a shaft, and the shaft has a race at both sides of an idling space in which the rotary component is turned. A guider of the assembly has tension ribs held in the race for allowing the rotary component to idle about a predetermined point on the shaft. In addition, in the inventive guider assembly, the shaft has a race formed at both sides thereof and on a part of its outer surface, and the guider has a shaft hole into which the shaft fits, and tension ribs formed at one side of the shaft hole and held in the race.Type: GrantFiled: June 15, 1998Date of Patent: February 29, 2000Assignee: SamSung Electronics Co., Ltd.Inventor: Nae-Wan Kang
