Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] see figure 1 , a rotor structure of an electric motor, including a rotor 3 and a power output shaft 4 .

[0018] The rotor 3 includes a rotor core 31 and several magnetic steel sheets 32 . The rotor core 31 is provided with a shaft hole 37 . The shaft hole 37 is coaxial with the rotor core 31 . The rotor core 31 is provided with several magnetic steel sheet mounting holes 33 extending axially of the rotor. The number of magnetic steel sheet mounting holes 33 is equal to the number of magnetic steel sheet 32 ​​. The magnetic steel sheets 32 are arranged in the magnetic steel sheet mounting holes 33 one by one. The magnetic steel sheet mounting hole 33 is a blind hole. The magnetic steel sheet mounting hole 33 is provided with a magnetic steel sheet pop-up spring 35 . The magnetic steel sheet spring 35 is located between the magnetic steel s...

Abstract

The present invention relates to electric machines. A rotor structure of a motor, including a rotor and a power output shaft, the rotor includes a rotor core and a plurality of magnetic steel sheets, the rotor core is provided with a shaft hole, and the two ends of the rotor core are provided with a plurality of fixing holes , the fixed hole extends axially along the circumferential distribution of the shaft hole, the power output shaft is composed of two shaft heads, and the shaft heads are installed in the shaft hole in a clearance fit manner, and the shaft heads A plurality of connecting claws are provided in the fixing holes in a one-to-one correspondence. The invention provides a rotor structure of a motor in which the rotor and the power output shaft are connected together through a new connection method, so as to change the traditional connection method of the rotor and the power output shaft, and make it convenient to disassemble the rotor and the power output shaft.

Description

technical field [0001] The invention relates to a motor, in particular to a rotor structure of the motor. Background technique [0002] A motor is a commonly used machine that provides power. Its basic structure includes a casing, a stator, a rotor and a power output shaft. End covers are provided at both ends of the casing. Both ends of the power output shaft are supported on the end covers through ball bearings. The rotor includes a rotor core and several magnetic steel sheets. The iron core is provided with a shaft hole, and the power output shaft is set to be much larger than the shaft hole, and then the power output shaft is inserted into the shaft hole by forceful compression of a large tonnage, and the two are deformed and stuck during the extrusion process. Tight together for threading torque. When the rotor and the power output shaft are connected by the above-mentioned existing conventional methods, it is inconvenient to separate the rotor and the power output sh...
