Abstract

The invention discloses a connecting structure of a motor spindle and a motor rotor, which comprises an inner cone sleeve which is arranged on the motor rotor; the left end of the inner cone sleeve is provided with a plurality of oil holes; the oil holes extend into the contact surface of the inner cone sleeve and the motor spindle; the oil holes are internal threaded holes; bolts are installed in the oil holes; and the oil holes form an angle of 15 DEG to 45 DEG with the motor spindle. According to the invention, the disassembly of the motor rotor is convenient; and the connecting structure has a simple structure and is convenient in utilization.

Description

technical field [0001] The invention relates to a connection structure, in particular to a connection structure between a motor shaft and a motor rotor. Background technique [0002] The connection between the motor rotor and the motor shaft has always been a concern in the field of motor manufacturing. The traditional motor stator installation method is realized by using interference fit between the motor rotor and the motor shaft. The shortcoming of this method is: 1, dismounting is not easy. 2. Energy consumption. 3. High technical experience requirements for installation workers. Bring great inconvenience for actual use. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a coupling structure between a motor shaft and a motor rotor. The invention can facilitate the disassembly of the motor rotor, and has simple structure and convenient use. [0004] In order to achie...
