Permanent visual indicator and diametrical to axial relation gage and method of using same
A system and method for mounting a bearing assembly on a shaft includes an internal flange, external flange, and a sleeve. The internal flange is securable to the bearing assembly and has a displacement pin extending outward that defines an initial position of the bearing assembly relative to the shaft. The external flange is secured to the internal flange via fasteners passing through elongated holes. The external flange has an opening configured to receive the displacement pin. The external flange may be rotated when coupled to the internal flange with the fasteners between a first position where the external flange opening is not in register with the displacement pin and a second position where the external flange opening is in register with the displacement pin. A sleeve has a tapered outside diameter and is engageable with the external flange.
1. A method comprising:
accessing a bearing kit comprising an internal flange, an external flange, a tapered sleeve and a bearing assembly, wherein the internal flange has a displacement pin extending axially outward from a surface of the internal flange by a pin dimension, the internal flange is axially secured to a bearing assembly, the external flange is mounted to the internal flange with a plurality of fasteners such that the external flange is spaced from the internal flange by the pin distance, the external flange has elongated holes configured to receive the plurality of fasteners, the external flange has an opening configured to receive the displacement pin;
engaging the tapered sleeve with the external flange to position the tapered sleeve at an initial position relative to the bearing assembly and the shaft;
placing the tapered sleeve over a shaft;
rotating the external flange relative to the internal flange with the fasteners in the elongated holes such that the external flange opening aligns with the displacement pin; and
engaging the plurality of fasteners between the external flange and the internal flange to move the internal flange toward the external flange and draw the bearing assembly over the sleeve such that the tapered sleeve is moved from the initial position to a final position of the sleeve relative to the bearing assembly and the shaft.
2. The method of claim 1 , wherein the external flange abuts the internal flange when the sleeve is at the final position with the displacement pin received in the external flange opening.
3. The method of claim 2 , wherein the pin dimension equals a distance between the initial position and the final position.
4. The method of claim 2 , comprising leaving the fasteners engaged between the external flange and internal flange to prevent relative movement of the sleeve during operation.
5. The method of claim 1 , wherein the displacement pin is one of a plurality of displacement pins extending from the internal flange at the pin dimension.
6. The method of claim 5 , wherein the external flange opening is one of a plurality of openings of the external flange configured to receive a corresponding displacement pin.
7. The method of claim 1 , wherein the sleeve is axially split allowing it to clamp the shaft when the tapered outside diameter is engaged.
8. The method of claim 1 , wherein the opening comprises a notch extending through an outer periphery of the external flange.
9. The method of claim 8 , further comprising applying a tool to the notch to rotate the external flange.
10. The method of claim 1 , wherein the external flange is threadably coupled with the sleeve.
