摘要
齿面印痕和传动误差对齿轮传动的性能起着决定作用,针对齿面印痕和传动误差,提出弧齿锥齿轮点啮合齿面主动设计的方法。该方法突破了传统齿轮设计的局限性,采用'局部共轭原理'和'局部综合法',并依据弧齿锥齿轮的加工原理,使齿轮设计人员能够按照要求的传动性能来设计齿面的形状,并可在摇台结构的铣齿机进行加工。齿面主动设计能保证齿面在整个啮合过程中满足预先设计的传动误差和齿面接触路径的要求,从而达到对齿面啮合质量的全程控制,它为弧齿锥齿轮副设计提供新的方法和途径,这对于高速和重载齿轮以及有特殊要求的齿轮的设计具有十分重要的意义。
Transmission errors and contact pattern have determinative effects on the gearing performances of a gear drive, so a new approach for design of spiral bevel gears is proposed, based on a predesigned parabolic function of transmission errors with limited magnitude of maximal transmission errors and a predesigned linear function of contact path. This approach is based on three meshing points. By controlling their magnitudes of transmission errors and the positions on the tooth surface, the allover control of engagement quality is realized. The advantages of the function-oriented active tooth surface design are the reduction of level of noise and the obtaining of favorable shape and dimensions of contact pattern, and moreover, the gearing performance in whole tooth contact could be controlled directly in design. The goals are achieved by application of local synthesis algorithm, local conjugate theory and machining principle of spiral bevel gears. Function-oriented active tooth surface design provides an innovative designing approach for the spiral bevel gears and is quite important for the gears in high speed, heavy duty or with special requirements.
