Claims

[Scope of Claim for Utility Model Registration] 1. Insert the impeller boss so that its back side end surface is in contact with the stepped portion of different diameter formed on the motor shaft, and tighten the shaft end side end surface of the boss with the main shaft end screw. In the impeller mounting device, the impeller is made of an elastic body, the length of the boss of the elastic impeller is longer than the length of the impeller insertion shaft, and the shaft of the impeller boss is longer than the length of the impeller insertion shaft. A washer having a flange surrounding the outer periphery of the impeller boss is brought into contact with both end surfaces protruding in the direction, and the inner diameter of the washer on the shaft end side is configured to be smaller than the outer diameter of the impeller insertion shaft. An elastic impeller characterized in that the elastic impeller is attached to a motor shaft with appropriate tension by screwing a nut into a threaded portion extending further outward and tightening the nut. mounting equipment. 2. An impeller mounting device in which the impeller boss is inserted so that the back end surface of the impeller boss is in contact with a stepped portion of different diameter formed on the motor shaft, and the shaft end side end surface of the boss is tightened with a main shaft end screw. wherein the impeller is made of an elastic body, the length of the boss of the elastic impeller is longer than the length of the impeller insertion shaft, and the impeller boss has a shaft end side end surface projecting in the axial direction. A washer having a flange surrounding the outer periphery of the impeller boss is brought into contact with the impeller boss, and the back end surface of the boss portion of the impeller is formed to be substantially flush with the end surface of the impeller main plate without protruding in the axial direction. A flat washer is embedded and installed in the part corresponding to the rear boss so that the end surface is aligned with the end surface of the impeller main plate, and the inner diameter of the washer on the shaft end side is configured to be smaller than the outer diameter of the impeller insertion part, and the impeller insertion shaft is An elastic impeller characterized in that the elastic impeller is attached to a motor shaft with appropriate tension by screwing a nut into a threaded part extending outward from the part and tightening the nut. Car mounting device.
