ANALYSIS OF DIMENSION CHAIN FOR ACCURACY ASSURANCE OF TOOTHING OF BEVEL GEARING
The article considers the accuracy parameters of toothing of bevel gearing and demonstrates the calculation of dimension chains to work out the permissible axel intersection of rotation of cohesive wheels, i. e. the permissible variation of center-to-center spacing. The deviation from coaxiality of mating parts, clearance in mating of components and other errors affect the accuracy of toothing. The calculation of dimension chains allows estimating tolerances and tolerance extremes of these parameters, and provides precision of bevel gearing assembly in the most economical way when manufactured, repaired and operated.
