The current lift more products: according to enhance power to mechanical and hydraulic two forms; according to the types of structures have a single column, double column, type and shear type. However, various types of lifting machine has its own advantages and disadvantages, is the topic of lifting machine optimization design, economical, suitable and better lifting machine. First of all, on the market used some of the lifting machine to carry on the analysis, combined with their advantages and disadvantages, I design and selection of mechanical drive for lifting machine power transmission. Transmission route: motor belt transmission - - - the main screw drive chain drive - Vice screw drive form. After several months of effort: 1) To complete the motor selection, selection of general purpose ( IP44) series of three-phase asynchronous motor, according to the overall structural arrangement, using horizontal sealing structure2) Completed to leg and arm calculation and checking3) Design of transmission system of spiral transmission4) Determine the screw diameter and height on the nut and screw and nut calculation5) Completed the lead screw nut structure safety design6) Determine the chain model 16A, the optional pitch P=25.47) To complete the V band selectionKey words: sliding screw screw chain belt of V Signature of supervisor:
