带传动软启动装置蜗杆的优化设计

The Optimize Design of the Worm Parameters in the Belt Drives Soft-start Equipment

根据对带传动软启动装置的受力分析,建立了以蜗杆轴向模数及螺旋升角为自变量的双目标函数。根据自锁约束条件及模糊约束条件,建立了约束子集。与普通设计参数相比,优化设计得到的螺旋升角增大,蜗杆轴向模数减小。试验表明,该优化设计可提高传动效率,降低调速电机最低功率。

By the mechanical analysis of the belt drives soft-start equipment,tow-objective function is established with the worm axial modulus and spiral angle as the independent variables.Based on self-locking constraint and fuzzy constraint conditions,constraint subset is established.Compared with the general design parameters,the rustle shows that the spiral angle is increased and the worm axial modulus is decreased.The test shows that the optimize design effectively improve the transmission efficiency,and reduce the minimum power of the speed adjustment motor.
