Claims

[Scope of utility model registration request]

(1) A flange consisting of a pair of opposing bearing surfaces and protruding in the radial direction with a width smaller than the bearing width formed on either of the bearing surfaces, making the bearing gap in this part smaller than in other parts; an annular groove formed on one of the bearing surfaces on both axial sides of the flange; and an annular groove formed on one of the bearing surfaces within the bearing width and on the axial outside of each annular groove.
A dynamic pressure type radial bearing comprising a plurality of grooves in the shape of an ``eight''.

(2) The motion according to claim 1 of the utility model registration claim, characterized in that one or more grooves are formed on either of the receiving surfaces so that the annular grooves located on both sides in the axial direction of the flange communicate with each other. Pressure type radial bearing.

(3) The dynamic pressure type radial bearing according to Claim 1 of the Utility Model Registration Claim, characterized in that the approximately "eight" shaped groove is configured with a left-hand thread and a right-hand thread.

(4) A practical use characterized in that cavities that function as lubricant retainers are formed on both sides of the collar portion in the axial direction, and a further collar that protrudes in the radial direction is located outside of each cavity in the axial direction. Dynamic pressure type radial bearing according to claim 1 of patent registration claim.

(5) Dynamic pressure according to claim 4 of claim 4, characterized in that the radial clearance in the further flange is larger than that in the first-mentioned flange, and (1) smaller than that in the void space. type radial bearing.
