Publication number: 20090190870Abstract: An outer needle bearing race and thrust washer assembly provides improved lubrication for a pinion gear of a planetary gear assembly. The bearing race and thrust washer assembly are used in pairs with the bearing races disposed within the planet or pinion gear and the thrust washers disposed adjacent the end faces of the planet or pinion gear. Each assembly includes a cylindrical bearing portion having a crowned, i.e., convex, inner surface which is secured at one end to a thrust washer. The outside face of the washer includes a plurality of shallow radial channels or grooves. A plurality of oil passageways extend from the grooved surface of the washer to its opposite surface inside the cylindrical bearing portion.Type: ApplicationFiled: January 25, 2008Publication date: July 30, 2009Applicant: GM GLOBAL TECHNOLOGY OPERATIONS, INC.Inventors: Joseph Young-Long Chen, Jack M. Gayney, Angela P. Willis, Hun J. Kim

Publication number: 20090103843Abstract: A number of machines such as gas turbine engines have asymmetric axial loading along a shaft (2, 3, 4). In order to accommodate for this asymmetric loading, known as an end bearing load, a load share bearing (103) is typically provided. However, specifying the fixed bearing (11, 12) becomes increasingly difficult as space and weight considerations are taken into account. In such circumstances providing a combination of a fixed bearing (11, 12) and a load share bearing (103) to achieve an acceptable bearing end load capacity is more acceptable. The proportion of the combination provided respectively by the fixed bearing and the load share bearing can be varied dependent upon operational stage in order to achieve more efficient operation.Type: ApplicationFiled: September 19, 2008Publication date: April 23, 2009Applicant: ROLLS-ROYCE PLCInventor: Alan R.

Publication number: 20090052818Abstract: One embodiment of a hybrid vertical axis rotating load carrying bearing with continuously variable operating conditions able to carry surprisingly heavy weight, and occasionally easily able to carry drastically more weight than that; The preferred embodiment has 3 different types of bearings combined to form one ideal bearing. The first type of bearing is a half ball and female sliding bearing. The second type of bearing is a floating bearing that surrounds the sliding bearing. The third type of bearing is rolling bearings. In this preferred embodiment with 3 different types of bearings, the rolling bearings are partially engaged under ideal load weight conditions, and nearly fully engaged under severe load weight conditions. The sliding and floating bearings are always fully engaged into the vertical weight load no matter what the vertical weight load may be. Another embodiment is the hybrid bearing containing two types of bearings; a floating bearing and rolling bearings.Type: ApplicationFiled: July 10, 2008Publication date: February 26, 2009Inventor: Jason Matthew Mitmesser

Publication number: 20090028481Abstract: A double row thrust roller bearing includes a pair of inner and outer cages arranged radially in two rows in separate coaxial relation, each cage including an annular inner peripheral wall, an annular outer peripheral wall, a plurality of pillar portions interconnecting the annular inner and outer peripheral walls at intervals in a circumferential direction thereof, and a plurality of pockets each formed between the adjacent pillar portions. Rollers are rotatably held and retained respectively in the pockets. The annular inner peripheral wall of the inner cage is guided by an annular flange formed at an inner peripheral edge of one race, and the annular inner peripheral wall of the outer cage is guided at an inner periphery thereof by the annular outer peripheral wall of the inner cage.Type: ApplicationFiled: July 23, 2008Publication date: January 29, 2009Applicant: JTEKT CORPORATIONInventor: Yoshitaka Waseda
