Abstract: Presents an approximate method of manufacturing internal bevoloid gear using bevel slotting technology. On the basis of deriving its profile surface equations, analyses the change of transverse pressure angle and the tooth form error caused by this manufacturing method, probes into the influence of the relative bevel angle in which the workpiece is machined upon thinning of tooth thickness, optimizes the relative bevel angle with the aim of crowning tooth and minimizing tooth form error. Theoretical analysis and experiment result both show that the bevel slotting technology is an effective method of manufacturing internal bevoloid gear when its bevel angle is less than 12°.
