The present invention will be described in detail with reference to fig. 1 and the following detailed description.
Referring to fig. 1, the present embodiment provides an auxiliary device for detaching a motor rotor of a range extender, which is applied to a stator and a rotor, wherein the stator and the rotor include a stator and a rotor that are matched with each other, and include an ejection nut 1, a screw rod 2 and a flywheel extension cover 3, the flywheel extension cover 3 is inserted into an air gap of the stator and the rotor, the ejection nut 1 is disposed in the middle of the flywheel extension cover 3 and connected to a mounting hole on a flywheel end surface of the rotor, and the screw rod 2 is screwed to the ejection nut 1; the flywheel extension cover is characterized by further comprising an ejector rod 4 inserted in the middle hole of the rotor, one end of the ejector rod 4 penetrates through the flywheel extension cover 3 and is connected with one end, back to the screw rod 2, of the ejector nut 1, and the other end of the ejector rod 4 is inserted into the center hole of the big end of the crankshaft.
The utility model discloses an increase journey ware electric motor rotor and dismantle auxiliary device adopts ejector pin 4 to carry out the rotor direction when using, prevents the stator-rotor actuation, pulls out the rotor with ejecting nut 1 and screw rod 2, further prolongs the flywheel that 3 support rotors through the flywheel, prevents that the rotor from damaging to protect stator and rotor when dismantling electric motor rotor effectively.
In this embodiment, still include two rotor guard plates 5, two rotor guard plates 5 set firmly at the motor casing terminal surface through first bolt, support the effect that the rotor flywheel played the protection rotor after the rotor took out from stator winding. Two rotor guard plates 5 are arranged along the central symmetry of the end surface of the motor casing. The two rotor guard plates 5 further prevent the rotor from being damaged, thereby effectively protecting the stator and the rotor when the motor rotor is disassembled.
In the present embodiment, the push-out nut 1 is attached to the attachment hole of the flywheel end face of the rotor by the second bolt, thereby increasing the stability of the push-out nut 1.
Although the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that modifications and improvements can be made thereto. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
