摘要
驱动电机为自动门的核心部分,机械传动强度和噪音成为自动们行业共性的问题,塑料蜗轮与钢制蜗杆传动是将塑料斜齿轮(即塑料蜗轮)代替金属蜗轮实现传递动力与运动的一种传动机构。文章主要根据材料的差异进行齿形强度的参数优化,研究解决自动门寿命和噪音技术难题。通过对塑料斜齿形横向正变位,端面加强筋注塑成型工艺,达到了产品100万次循环的寿命测试。
Drive motor is the center of automatic door. The strength and noise of the mechanical drive become the common problem in the auto-door industry. The drive about plastic and steel worm is one kind of drive mechanism, to use the plastic bevel gear as plastic worm replacing the steel one for realizing the driving force and motion. The article studied the parameter optimization of gear tooth strength based on the material variance, to solve the technologic problems on auto-door life span and noise. Through the positive transverse deflection of the plastic bevel tooth form and the reinforced injecting molding of the end face, the life span reaches 1 million cycles for testing.
