Abstract

PURPOSE:To increase the allowable number of revolution and obtain an antifriction bearing which endures high-speed revolution by installing at least one rotary intermediate ring between the outer and the inner rings and arranging each plurality of rolling bodies between the rings. CONSTITUTION:At least one rotary intermediate ring 12 is installed between an outer ring 10 and an inner ring 11, and each plurality of outer and inner rolling bodies 13 and 14 are arranged between the rings 11-12. A rotary shaft is inserted into the inner ring 11, and the outer ring 10 is fixed onto a casing. The inner rolling body 14, intermediate ring 12, and the outer rolling body 13 are revolved through the revolution of the inner ring 11. Therefore, the allowable number of revolution can be increased, and an antifriction bearing which endures high-speed revolution can be obtained.
