Patent number: 6981801Abstract: A roller bearing cage is disclosed in which a pair of semicircular cage halves is assembled with their mating ends thereof coming into abutment against each other. The mating ends are chamfered off to stave off bearing failure resulting from any deformation that might occur at the areas nearby the mating ends owing to large centrifugal force imposed by high-speed engines. The roller bearing cage may be completed by only joining together the semicircular cage halves with their diametral mating ends coming into engagement with one another. Each of the semicircular cage halves is composed of axially opposing semicircular rims and cage bars interposed between the rims, thus helping ensure stiffness with even weighing less. The chamfering operation is done to make even any outer peripheral areas nearby the mating ends, preparatory to cutoff operation to split a cylindrical cage stock into two halves. This helps the process management of material-removal work to make the chamfered even areas.Type: GrantFiled: October 20, 2003Date of Patent: January 3, 2006Assignee: Nippon Thompson Co., Ltd.Inventor: Yasunori Yokota

Patent number: 5184899Abstract: A needle roller bearing of a type empolying a generally cylindrical needle roller retainer of two-piece construction for supporting a plurality of needle rollers. The roller retainer is comprised of retainer segments each having opposite side edges. The retainer segments are connected together by means of at least one bond deposit filling up a gap between one of the opposite side edges of one of the retainer segments and a mating one of the opposite side edges of the other of the retainer segments, respectively. As a bonding material forming the bond deposit, a viscous material containing, as a principal component, vinyl acetate resin, or a hot-melt bonding material, both exhibiting a bondability lowering a high temperature, may be employed. When the needle roller bearing is in use, the bond deposit detaches from the gap or melt to separate the retainer segments from each other, allowing the separated retainer segments to function individually to minimize a fretting phenomenon.Type: GrantFiled: June 24, 1992Date of Patent: February 9, 1993Assignee: NTN CorporationInventor: Kazuyoshi Harimoto
