Method of manufacturing a double-headed tapered roller for double-headed tapered roller bearing

摘要

PPROBLEM TO BE SOLVED: To inexpensively provide a both-head tapered roller type rolling bearing of low friction, high rigidity and high durability in a thrust receiver, as to durability and energy-saving of a compression and expansion machine of scroll type. PSOLUTION: A both tapered roller is manufactured by making rod-likely connected both-head tapered rollers and by separating those to be used, and a posture and direction of a rolling element are held by a head part tip. The both-head tapered roller type rolling bearing is constituted to engage head part protrusions of the both-head tapered roller with pin holes of two races, to make an outer circumference of the rolling element slide-contact with an inner wall of a holding hole in a trochoid locus, and to prevent thereby the races from being separated.
