Principle and Analysis of Grinding Helical Gear of Triangular End Relief with Large Plane Grinding Wheel
摘要
Abstract
In order to reduce the fluctuation of loaded transmission error as an excitation of vibration,the triangular end relief optimization design of helical gear and the grinding principle of large plane grinding wheel are proposed.According to the equation of standard involute and definition of triangular end relief,the starting line of modification of tooth top and tooth root was calculated.According to the order of modification curve and the maximum modification amount,the modification surface was determined.The modification surface was superimposed in the normal direction of the standard helix surface to obtain the theoretical modification tooth surface.With the help of the tooth contact analysis(TCA)and loaded tooth contact analysis(LTCA)method,the corresponding triangular end relief parameters are optimized with the genetic algorithm with the minimum loaded transmission error fluctuation as the objective function.The minimum diameter of large plane grinding wheel was derived,and the tooth surface equation of triangular end relief generated by large plane grinding wheel was derived in terms of the concept of imaginary helix rack-cutter.The results of numerical examples show that through triangular end relief optimization,the different order of modification curves can reduce the loaded transmission error fluctuation,the higher the order,the more obvious effect,up to 82.58%.When grinding with large plane grinding wheel,tooth surface deviation will be produced,but the deviation is controlled within 2 μm,so as to achieve high tooth surface accuracy,and the method is easy to be realized with the numerical control(NC)programming.关键词
