    摘要： A sleeve and a splined shaft are coupled for rotation in unison and for relative linear movement by trains of anti-friction balls which circulate in pairs of load and return grooves circumferentially spaced from one another around the sized surface of the sleeve. The return grooves are size to receive the balls with free running clearance, and the balls are always in an unloaded or free return condition while traveling in the return grooves, the same grooves serving as return grooves at all times regardless of the direction of rotation of either the sleeve or the shaft. The load grooves are smaller than the return grooves, and the balls in alternate ones of the load grooves are loaded and transmit torque in one direction of rotation while the balls in the other load grooves are loaded and transmit torque in the opposite direction of rotation. If desired, the balls may be sized to fit between the load grooves and the shaft with zero clearance to establish an anti-backlash fit between the shaft and the sleeve. Also, the sleeve may be preloaded on the shaft simply by using balls sufficiently large to be deformed plastically between the load grooves and the shaft.

    摘要： The rollers of a recirculating roller way bearing are crowned convexly to distribute the loading on each roller more uniformly across the entire length thereof and thereby increase the loadbearing capacity of the roller and to reduce skewing caused by excessive and unequal loading on the ends of the roller. Straptype retainers hold the rollers in the race of the bearing without guiding the rollers as they circulate so as to leave the bearings free to align themselves in the race.
