Claims

[Scope of utility model registration request]

A rotating shaft having a central hole for oil supply along the central axis and oil supply holes branching radially from the central hole, a pair of bearing metal and the same bearing that can relatively slide along the outer peripheral surface of the rotating shaft. A floating ring having an oil supply chamber formed between metal parts and communicating with the oil supply hole, and a casing disposed outside the floating ring forming an annular auxiliary oil supply chamber. The casing is provided with a refueling port that communicates with the annular auxiliary refueling chamber, and the floating ring is provided with an oil hole that allows communication between the refueling chamber and the auxiliary refueling chamber, while a half-split is provided at both ends of the casing. A bearing casing with a mounting part at the lower end is joined,
A circumferential oil supply device characterized in that a bearing metal for rotationally holding the rotating shaft is attached to the inner circumferential surface of each bearing casing.
