ROTARY SHAFT FOR INDUCTION MOTOR, CAPABLE OF REDUCING NUMBER OF PARTS AND SIMPLIFYING ASSEMBLY PROCEDURES BY AVOIDING USE OF STOPPER RING

摘要

PURPOSE: A rotary shaft for induction motor is provided to reduce the number of parts and simplify assembly procedures by avoiding use of a stopper ring. CONSTITUTION: A rotary shaft(31) comprises a rod type rotary shaft body(32) and a bearing stopper(34). The rotary shaft body is integrally coupled to an axis center of a rotor core(11) in such a manner that the rotary shaft body is rotatable. The bearing stopper is coupled to both sides of the rotor core along a lengthwise direction of the rotary shaft body. The bearing stopper is formed integrally with the rotary shaft body and protruded in a radial direction of the rotary shaft body, in such a manner that bearings supporting the rotary shaft body are prevented from contacting with each other.
