Title:
WEIGHT CALKING HORN
Document Type and Number:
Japanese Patent JP3456088
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent the break of the base of a weight calking horn even if it comes to high-speed rotation, by providing the base of the weight calking horn at the place one step under the end face of an end ring, and further, connecting the base of the weight calking horn with the end ring in a curved line.
SOLUTION: The base 1a of a weight calking horn is provided at the place one step under the end face of an end ring 2, and further the line of connecting the base of the weight calking horn with the end face of the end ring 2 is curved. Hereby, the stress of the base la of the weight calking horn can be relaxed, and further the weight calking can be made surely, so the break of the base 1a of the weight calking horn caused by the centrifugal force at high- speed revolution can be prevented.
