Computing method of instrument circular gear drive for reduction

Chen Wenhua(Dept.of Mechanical Enggnerring, Zhejiang University,Hangzhou,310027 )  
n this paper,first,author proves that the straight tooth profile of gear will not mesh withpinion. Then,according to the straight tooth profile of pinion meshing with gear or not,and differentlocations of approach and recess point,the author classifies meshing processes into two types and sixkinds.Thirdly,the author derives the formulas used to determine the approach angle and recess angleon all kinds of working processes,and the criterion to distinguish concrete working process.Eventually,the author presents the formulas to compute drive performance targets of this kind ofinstrument gear drive.
