Claims (1)

[Claims for Utility Model Registration] (1) A mounting flange is fixed to the end of a rotating shaft that is rotatably supported via a plurality of rolling elements inside an outer ring that is fixed to a mounting support part. In the rotary shaft unit with a mounting flange, the end of the rotary shaft is inserted into the circular hole formed in the center of the mounting flange without wobbling, and the inner peripheral surface of the circular hole and rotation 1. A rotary shaft unit with a mounting flange, characterized in that an outer circumferential surface of an end of the shaft engages with a concave-convex surface to prevent at least the mounting flange from moving away from the outer ring. (2) The mounting flange moves away from the outer ring due to the engagement between the edge of the large diameter portion formed at the end of the rotating shaft and the small diameter portion formed on the inner peripheral edge of the circular hole closer to the outer ring. A rotating shaft unit with a mounting flange according to claim 1 of the utility model registration, which prevents the above. (3) The relationship between the outer circumferential surface of the tapered part formed at the end of the rotating shaft, whose outer diameter increases toward the end, and the inner circumferential surface of the tapered circular hole, whose inner diameter decreases toward the outer ring. The rotating shaft unit with a mounting flange according to claim 1, wherein the mounting flange is prevented from moving in a direction away from the outer ring. (4) The mounting flange is prevented from moving away from the outer ring by engagement between the groove formed on the outer peripheral surface of the end of the rotating shaft and the protrusion provided on the inner peripheral surface of the circular hole. , a rotating shaft unit with a mounting flange according to claim 1 of the registered utility model claim. (5) a concave hole formed on the outer peripheral surface of the end of the rotating shaft;
The rotating mounting flange according to claim 1 of the patent registration claim, wherein the mounting flange is prevented from moving away from the outer ring by engagement with a protrusion protruding from the inner circumferential surface of the circular hole. axis unit. (6) The rotating shaft unit with a mounting flange according to any one of claims 1 to 5 of claims 1 to 5 of the utility model registration, in which the end face of the rotating shaft and the peripheral edge of the circular hole formed in the center of the mounting flange are welded. . (7) The end of the rotating shaft and the circular hole formed in the center of the mounting flange are connected by shrink fitting;
A rotating shaft unit with a mounting flange according to any one of claims 1, 3, 4, and 5 of the utility model registration claim.
