Manufacturing method of AC vertical drive device
A vertical AC drive device, characterized in that it includes a shock-absorbing bracket, a traveling drive motor, a steering drive motor, a reduction gear box, and a driving wheel, wherein the shock-absorbing bracket includes a fixed frame vertical plate, a guide column fixed pressure plate, and a floating frame Base plate, guide post, guide ring, guide cylinder, booster spring, spring seat, limit bolt, upper left fixing seat, upper right fixing seat, lower left fixing seat and lower right fixing seat, the fixing frame is fixed on the frame upright , Two guide posts arranged symmetrically are arranged on the fixing frame, the upper ends of the two guide posts are respectively fixed on the upper left fixing seat and the upper right fixing seat, and the guide column fixing pressure plate is fixed on the upper left fixing seat and the upper right fixing seat , The lower ends of the two guide posts are respectively fixed on the lower left fixed seat and the lower right fixed seat, the lower left fixed seat and the lower right fixed seat are fixed on the fixed frame vertical plate, and the floating frame bottom plate is fixed with two symmetrically arranged A guide cylinder, the lower end of the guide cylinder is fixed on the bottom plate of the floating shelf, a guide ring is provided in the guide cylinder, and the guide column is inserted into the guide cylinder in the guide cylinder, so as to realize the sliding connection between the bottom plate of the floating shelf and the fixed frame Between There are two limit bolts, and two bolt connecting holes for the limit bolts are inserted in the guide column fixing pressure plate, the limit bolts are inserted into the bolt connecting holes, and the head of the limit bolt is bolted because the size is larger than the bolt connecting hole The connection hole is limited above the bolt connection hole, two spring seats are symmetrically arranged on the bottom plate of the floating frame, the lower end of the spring seat is fixed on the bottom plate of the floating frame, the spring seat is sleeved with a booster spring, and the upper and lower ends of the booster spring It respectively abuts on the fixed pressure plate of the guide column and the bottom plate of the floating frame. The spring seat is provided with threaded holes for the threaded connection of the limit bolts. The two limit bolts are respectively inserted into the two booster springs and the lower ends of the two limit bolts are respectively Connect the threaded holes on the two spring seats, the steering drive motor and the travel drive motor are fixed on the upper surface of the bottom plate of the floating frame, and the large rotating bearing is fixed on the lower surface of the bottom plate of the floating frame. The steering gear is fixed below the large slewing bearing, so that the steering gear is rotatably installed on the bottom plate of the floating frame, the reduction gear is installed on the steering gear, and the rotating shaft of the driving wheel is horizontal It is placed and fixed on the output shaft of the reduction gearbox. The output shafts of the steering drive motor and the travel drive motor are all set vertically. The output shaft of the travel drive motor passes through the bottom plate of the floating rack and is connected to the input shaft of the reduction gearbox. Therefore, the driving wheel on the reduction gear box is driven to rotate by the driving motor to achieve the traveling action. The output shaft of the steering drive motor passes through the floating floor and is connected to the steering gear through gear transmission, so that the reduction gear box is driven by the steering drive motor The body realizes the steering action, and the traveling driving motor adopts an AC motor.
