In this paper a technigue of the change gear set calculation for minimizing the angle deflection of tooth curve on hobbing the cylindrical spur and spiral gear with prime tooth number greater than 100 as well as other cylindrical spiral gear were discussed. The numerical examples operated on microcomputer illustrated that by applying the derived formulas of the change gear set calculation and error check, as well as the procedure of seeking the optimal combination of change gear sets of related gearing chains of the hobbing machine, the angle deflection of tooth curve of the gear under hobbing, induced by the de-viation of change gear ratio from theoretical transmitting ratio, can be evidently and conveniently reduced.

This paper discusses that in order to get a. qualified hobbed gear,an arrangement of the ideal change gear ratio on. the machine is very important. However, in the case of no theoretical change gear ratio obtainable, the accept- able .allowance should be considered for working on a good enough hobbed pro- duct. Hcreof, we proceed on the theoretic analyses separately to the optimum allowances of the change gear ratio, such as for hobbing the bevel gear,the large prime number gear,and the spur or bevel gear on...

This paper discusses that in order to get a. qualified hobbed gear,an arrangement of the ideal change gear ratio on. the machine is very important. However, in the case of no theoretical change gear ratio obtainable, the accept- able .allowance should be considered for working on a good enough hobbed pro- duct. Hcreof, we proceed on the theoretic analyses separately to the optimum allowances of the change gear ratio, such as for hobbing the bevel gear,the large prime number gear,and the spur or bevel gear on a machine of no differen- tial mechanism. Also, the relevant calculating formulae are presented.
