The main purpose is to transfer the motion of the high speed low torque device through relevant mechanical mechanism into a low speed high torque transmission. Main task is to design and plete the reducer gear in puting and assembly, the main task contain the choice of motor to the belt transmission design and calculation, to the design and calculation of gear and shaft design and calculation, finally according to the size of the selected gear and shaft in accordance with the relevant standard plete enclosure design and other related parts and ponents selection. The most important part of this design is the core of gear transmission part of the selection calculation and design calculation and check of each gear shaft is chosen in the design of helical gear, chose a helical gear is mainly in order to ensure the stability of the transmission and the use of the relationship between the two vice gear and reverse loading offset part of the axial force, residual axial force to offset by selecting the appropriate bearing, tapered roller bearings are the main choice in the design. Another window of this design is to use puter instead of traditional manual calculation, the main use is the Solidworks software, the software is mainly used to plete the 3D entity model, and then through the explosion view more clearly express of the structure principle to this device, and the use of the software of puting functions is to plete the checking calculation of gear and shaft. Keywords: gear; drive shaft; transmission ratio。; transmission efficiency 蘭州交通大學(xué)畢業(yè)設(shè)計(jì) III 式輸送 機(jī)傳動(dòng)裝置的設(shè)計(jì) IV 目 錄 摘 要 .......................................................................................................................................
