Abstract

PURPOSE: To improve reliability of rotor by equalizing temperature on the surface of a shaft in provision of a key groove in circumferential direction on the shaft of a wheel part.
CONSTITUTION: After making shrinkage fit of a wheel 5 on a shaft 3, a key 18a is inserted through a groove 27 installed on the wheel 5, the key 18a is put into a key groove 16 installed on the shaft 3 and a groove 24 for lock key, which is fixed on the shaft 3 with use of bolts. The end 27 of a groove 28 for a wheel 5a borders on the end 25a of the key 18a. On the other hand, the end surface 26 of a thrusting part 23 of the key 18a is contrived so as to border on the end surface 13 of the wheel 5a. In consequence, by reason of non-existence of the key groove in the axial direction of internal diametral surface of the wheel, the external diametral surface of the shaft becomes equal temperature, to decrease vibration.
