APPARATUS FOR REDUCING TRANSVERSE VIBRATION OF A PUMP SHAFT

摘要

PURPOSE: A device for reducing transverse vibration of a pump drive shaft is provided to improve the drive efficiency of a pump by accurately transferring the torque from a drive motor to the pump. CONSTITUTION: A device for reducing transverse vibration of a pump drive shaft comprises a connection shaft(110), a main body(120), and a support bearing(130). The connection shaft connects the rotary shaft(220) of a pump(200) and a drive shaft(300). The main body is fixed to the case(210) of the pump and is extended in the longitudinal direction of the connection shaft so that the rotary shaft of the pump and the connection shaft can be located at the inner side of a through hole(121). The support bearing is installed inside the through hole and rotatably supports the connection shaft.
