Abstract
A pin which acts as a spring directly extends through an outer race without use of an outer-race casing and a pin holder and the central portion of the pin supports the outer race. Axial movement of the pin beyond a predetermined range is restricted by snap rings fitted on the both ends of the pin. An oil film is formed between the outer peripheral surface of the outer race and the inner peripheral surface of casings and oil reservoirs are also defined to damp axial movement of the outer race. That is, the pin which acts as a spring directly extends through the outer race of the bearing in parallel with a rotating shaft and the central portion of the pin elastically supports the outer race. The ends of the pin are supported by the casings through the snap rings. A space in which an oil film functioning as an oil film damper is formed is defined by the outer peripheral surface of the outer race and the inner peripheral surface of the casings. Furthermore, the oil reservoirs which act to damp the axial movement of the outer race are defined by the end faces of the outer race and the casings.
