A motor reel integrated lifting device structure

Abstract

The invention belongs to the technical field of motor and crane manufacturing, and provides a motor reel integrated lifting device structure. The hollow main shaft passes through the stator core a, stator core b and end cover, and the lifting reel is arranged on the stator core a and the stator core a. Outside the core b, the ends of the stator core a and the stator core b are respectively provided with stator coil a and stator coil b, and the permanent magnet a and permanent magnet b are arranged inside the lifting drum; The two ends of the hollow main shaft are also fixedly connected with rigid supports, the large synchronous wheel is fixed on the oil seal, the synchronous wheel mounting seat is fixed on the rigid support, the small synchronous wheel is fixed on the synchronous wheel mounting seat, and the small synchronous wheel passes through the synchronous The belt is connected with the large synchronous wheel; the height limiter is connected with the small synchronous wheel through the auxiliary shaft, and the encoder is connected with the height limiter through the elastic coupling. The structure of the device simplifies the production and assembly process of the permanent magnet, reduces the deformation of the main shaft, and provides a guarantee for the reliable operation of the motor.

Description

technical field [0001] The invention belongs to the technical field of motor and crane manufacturing, and mainly relates to motors and cranes, in particular to a motor reel integrated lifting device structure. Background technique [0002] The motor reel integrated lifting device has the advantages of small size, light weight, simple structure, high efficiency, and direct drive control. It is suitable for applications with low speed and high torque. be widely used. [0003] In some special lifting occasions, if the lifting height is relatively high, that is, high head, for the motor-drum integrated lifting device, there must be a drum long enough to accommodate the wire rope due to the height, that is, the length of the drum. rope capacity. But for the motor, the stator core does not need to be so long, but the rotating shaft of the motor needs to match the reel. If the stator of the motor is installed in the middle of the rotating shaft, the process of assembling the per...

AI Technical Summary

Problems solved by technology

If the stator of the motor is installed in the middle of the rotating shaft, the process of assembling the permanent magnet will be very difficult because the reel is too long. If it is installed at one end, the slender shaft is easily deformed.

Therefore, the traditional structure is difficult to meet the situation that the reel and shaft are very long and the stator is very short, and it is easy to cause the rubbing phenomenon of the stator and rotor during the operation of the lifting device, and burn the motor
