Study on Modification Method and Dynamic Characteristics of Spiral Bevel Gear Surface with High Contact Ratio
In order to suppress the vibration of spiral bevel gear transmission with high contact ratio,a new high-order tooth surface modification method was proposed.According to the meshing characteristics of spiral bevel gears with high contact ratio,a new modifica-tion curve was proposed,and the high-order modified spiral bevel gears were generated by using the auxiliary tooth surface modification method.Considering the tooth deformation,the load transfer error and meshing impact of high-order modified spiral bevel gear transmis-sion were calculated.On this basis,an optimization model for reducing the load transfer error and meshing impact of high contact ratio spiral bevel gear transmission was established.The simulation results show that compared with the second-order modified spiral bevel gear,the high-order tooth surface modification method can not only effectively reduce the load transmission error,meshing impact and dynamic load factor of the spiral bevel gear with high contact ratio,but also improve its dynamic performance in the full speed range.
