Diesel engine monorail suspension half motor drive device
The half motor drive device consists of a hydraulic half motor,a driving walking wheel,a guide wheel,a braking device,a clamping oil cylinder,and a valve group.The half motor is connected to the friction wheel through a transition bearing seat,and the clamping method of the two friction wheels is a track horizontal translation type.The advantages of this drive device are good clamping effect and long motor service life.The disadvantage is that the structure is relatively complex,and the workload of assembly and maintenance is large.
Diesel engine monorail crane full motor drive device
The full motor drive device consists of a hydraulic full motor,a driving walking wheel,a guide wheel,a braking device,a clamping oil cylinder,and a valve group.The hydraulic full motor is directly connected to the friction wheel,and the clamping structure of the two friction wheels is hinged.The advantage of this driving device is that the driving part has a simple structure and convenient maintenance.The disadvantage is that when the driving part requires a large clamping force,the motor output shaft and shaft seal are easily damaged.
Permanent magnet integrated machine drive device
The frequency converter and permanent magnet motor form an integrated machine,which has the advantages of high power density,precise control,and reliability.By connecting with the frequency converter,independent control of each driving part can be achieved,that is,adaptive speed regulation and adaptive swing drive can be achieved.
Asynchronous motor drive device
The driving device is composed of a frame,a load-bearing wheel,a driving wheel,a three-phase asynchronous motor,a reducer,and a braking device.The equipped braking device is a fail safe type,and the brake is opened by hydraulic power during walking;When encountering excessive speed or hydraulic system failure,the brake system implements emergency braking.
