Rotor shaft provided with reinforcement sleeve for stable connection

Abstract

The invention discloses a rotor shaft provided with a reinforcement sleeve for stable connection. The rotor shaft comprises a shaft body, an impeller and the reinforcement sleeve. One end of the shaftbody is connected with the impeller. A hole allowing the shaft body to be led in is formed in the center of one end of the impeller. The reinforcement sleeve is arranged at one end of the impeller. An opening allowing the shaft body to be inserted is formed in the center of the reinforcement sleeve. One end of the shaft body is led in the hole of the impeller through the opening of the reinforcement sleeve to be fixed. Multiple threaded holes are formed in the reinforcement sleeve and are annularly arrayed around the axis of the reinforcement sleeve. Tightening bolts are led in the multiple threaded holes correspondingly. The tightening bolts abut against the outer wall of the shaft body after being led in the threaded holes. Multiple oil filler holes are further formed in the reinforcement sleeve. By means of the manner mentioned above, the connection position of the shaft body and the impeller can be reinforced, it is avoided that the shaft body and the impeller slip out by accident, and the oil filler holes are formed so that a lubrication effect can be achieved.

Description

technical field [0001] The invention relates to the field of rotor shafts, in particular to a rotor shaft installed with a reinforcing sleeve for stable connection. Background technique [0002] The rotor shaft and body refer to forgings with sufficient mechanical strength, which can withstand the torque from the prime mover and the huge electromagnetic torque of sudden short-circuit at the generator outlet, and have good magnetic conductivity, and are the carrier of the main magnetic pole of the generator. . The rotor shaft is also used as an accessory of the marine compressor, and it is used in conjunction with the impeller. The traditional connection between the rotor shaft and the impeller is only fixedly connected in a single way, and there is a possibility that the rotor shaft may accidentally come out during high-speed operation. , easy to cause damage to parts. Contents of the invention [0003] The technical problem mainly solved by the present invention is to p...
