Abstract
What author of this text study numerical control main transmission of lathe mainly, the main design of transmission can use for to ordinary transformation of lathe, In order to adapt to the current situation of the present industrial development of lathe of our country, have certain economic benefits and social benefit.
The design that the author of this text finished includes according to some initial data mainly( type, specification of including the lathe ,etc.) Combine actual condition and situation draft to some parameters of lathe, and then according to the parameter drafted, Carry on the comparison of the transmission scheme, confirm the transmission scheme. It then can't calculate every transmission transmission of the packs than and gear wheel tooth count, estimate modulus and the every axle foot-paths of axle of gear wheel more, And check the intensity, rigidity of gear wheel and axle . In addition, will design the main structure in the body of the case , the selecting types of some parts, Electromagnetic choice of clutch,etc., finish to whole main design of transmission for instance.
