| Abstract: | Based on the space engagement theory,the space position of cutter was analyzed when the tooth profile of a higher-order elliptical bevel gear was generated,a mathematical model of higher-order elliptical bevel gear’s tooth profile was established;and then tooth surface equation of higher-order elliptical bevel gear was derived,pseudo-entity and assembly model of higher-order elliptical bevel gear were also acquired.Manufacturing methods by five-axis CNC of higher-order elliptical bevel gear were discussed,by the processing and mesh experimental research of a higher-order elliptical bevel gear pair,comparisons between experimental results and theoretical analysis was made to verify the mathematical model of higher-order elliptical bevel gear’s tooth profile,and the feasibility of processing methods shows the processing methods can be used in the actual machining. |
