This design from descend to reach mission to rise, investigate and check cultural heritage data to commence through the spot, experience successively time to complete for three month. In the design, first according to the technique parameter requested by topic assurance the tool machine design in the parameter needed, namely the power, tool machine principal axis box of prime mover turn soon few rows Mr. a ratio; Then make sure a tool machine principal axis the lord of the box to spread to move system structure, draw up the structure net of tool machine and turn soon diagram; Check data, turn soon according to the calculation of each main spare parts turned soon diagram an assurance inside tool machine, turn soon certain all levels and spread and spread and move a ratio dynamically according to the calculation, according to spread and move ratio and spread number of teeth that the dynamic wheel gear matches with a number to the certain all levels. According to tool machine principal axis box the error margin of which spread to move a chain to compute all levels to turn soon actual value and theories value. At mainly need to compute a principal axis box to choose to use in each spare parts in the design whether satisfy to request and prime mover and principal axis box of the motive deliver the calculation of device. The calculation of principal axis box includes the school of the school pit, principal axis of the school pit, key of the school pit, bearings of the school pit, stalk of school pit, wheel gear of rubbing the clutch to calculate calculate etc.The motive of the prime mover and principal axis box's delivering taking to spread to move device is adoptive. Finally according to data and make reference to the same kind tool machine to design electricity and liquid of computing the tool machine to press system, and draw its principle diagram.
Keywords: Turn soon few rows; Mr. Ratio; Structure net; tachogram; the calculation turns soon; Turning soon few words Mr. a ratio.
