Abstract:
1. A tapered roller bearing fabricating system comprising: a stock portion configured to stock a plurality of tapered rollers loaded from above in a stacked-up state in an inside of the stock portion; a tapered roller supply portion configured to separate a lowermost tapered roller from the other tapered rollers, which are positioned above the lowermost tapered roller in upstream and downstream directions, in the plurality of tapered rollers to be discharged from the stock portion so as to allow the tapered rollers to drop sequentially one by one when they reach a lowermost position, wherein the tapered roller supply portion includes: the plurality of tapered rollers are separated one by one in the upstream and downstream directions by the spiral grooves on the radial side surfaces of the pair of cylindrical members and the guides so as to allow the tapered rollers to drop sequentially one by one when they reach a lowermost position; and a cage; a rotation mechanism configured to rotate the cage disposed on the rotation mechanism; and wherein one revolution of one of the rotatable cylindrical members is synchronized with one pitch of the cage.
