摘要： The object is to reduce the contact surface pressure between the balls and the retainer of a thrust ball bearing at slide contact positions, thereby suppressing the wear of the retainer. By increasing the depth of drawing of inner and outer portions embracing the balls received in pockets of the retainer, when the balls roll on the raceways of the outer ring and the inner ring, the balls and the retainer are adapted to slidably contact each other at three portions, i.e. the peripheral edge of each pocket, and the outer portion and the inner portion of the retainer. Thus, it is possible to reduce the contact surface pressure at the respective slide contact positions compared to the prior art. Thus, it is possible to suppress the wear of the retainer.

The radially extending section of the first race and the axially extending section of the second race define a first annular gap. The radially extending section of the second race and the axially extending section of the first race define a second annular gap. Preferably, the inlet is in fluid communication with the first annular gap and the outlet extends axially through the cage and is aligned with the second annular gap.

摘要： A support structure carries a thrust load of a transmission which includes a torque converter having an impeller and a turbine opposite to each other with a stator therebetween. A thrust needle roller bearing having needle rollers arranged in two rows is provided at, at least one of places respectively between the stator and the impeller and between the stator and the turbine. The support structure carrying a thrust load of the transmission, a method of manufacturing the support structure and the thrust needle roller bearing are thus obtained, with an improvement in inflow and outflow of a lubricating oil, a reduction of the differential slip of the needle rollers, and an improvement in strength durability.

摘要： 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.
