Research of the non-involution characteristic of thermal deformation Gear

Makes a thorough analysis of the temperature field and thermal deformation in involute gear,and points out that the theoretical curve and the practical curve are not superposition when the temperature of the gear is changed.This is the non-involute characteristic of gear.At the same time,the non-involute error is calculated by using a thermal transferring theory and this error is one of factors influencing the total profile error.
