For achieving the above object, the present invention provides following technical scheme:
A kind of motor running rotating shaft, including rotating shaft body and axle sleeve, the spindle nose place of described rotating shaft body is provided with the shaft shoulder, described axle sleeve one end is set in rotary head place of rotating shaft body, described rotating shaft body is further opened with the keyway near rotary head, the centre of rotating shaft body is provided with first body of rod and second body of rod, second body of rod end face is provided with outer tie rod, the end face of outer tie rod offers slot, first body of rod end face is provided with the U-shaped inside connecting rod coincideing with outer tie rod, described first body of rod and second body of rod are equipped with reinforcement, and reinforcement is perpendicular to first body of rod and the outer surface of second body of rod, the medial surface of described outer tie rod offers arc groove, the lateral surface of described inside connecting rod is provided with the groove corresponding with arc groove, spring it is placed with in groove, the upper end of spring is connected to hoodle.
As the further scheme of the present invention: be provided with internal spline in the circular hole of the described axle sleeve other end.
As the further scheme of the present invention: described keyway body circumferential surface around the shaft is provided with three, four or six.
As the further scheme of the present invention: the both sides of described first body of rod and second body of rod are arc-shaped.
As the present invention further scheme: the diameter of described hoodle is more than the opening part diameter of groove, and less than the inside diameter of groove.
Compared with prior art, the invention has the beneficial effects as follows: machine shaft simple in construction of the present invention, secure and reliable connection, easy for installation quickly, the ventilation and heat area of rotating shaft increases, and can improve the result of ventilating heat dissipation of rotor, improve the service behaviour of electromotor, extend the service life of electromotor and rotating shaft；And off-axis can be prevented effectively from or cause because rotating shaft deflection is excessive rotor to wipe mutually, the bearing being assemblied on shaft end axle can be played a very good protection.
