自动门:齿轮减速电机的选择

齿轮减速电机的选择

齿轮减速电机由一个电动机和一个齿轮减速器组成,并形成一个结构单元。

减速器选择的准则包括空间的可用性、安装的可能性和与工作设备的连接情况。斜齿

轮、轴装斜齿轮、斜齿轮-锥齿轮和斜齿轮-蜗杆减速电机都可以选用。

除了斜齿轮-蜗杆减速电机外,其他所有减速器的啮合效率均相当高,不论

齿轮的级数多少,都在94%~98%之间。斜齿轮-蜗杆减速器的啮合效率小于50%则减速

器是静态自锁的,因此这种驱动装置只能用于不产生反向驱动转矩或反射驱动转矩很

小,不会操作减速器的情况。

齿轮减速电机作为设备的驱动装置,已有专业厂家生产各种类型的齿轮减速

电机,可满足各种场合的使用,只要确定了功率、输出转速、输出转矩和使用系数后

就可确定齿轮减速电机的参数,根据安装形式可最后选定齿轮减速电机。

自动门旋转门设计中,有时选用已有的齿轮减速电机,有时采用已有的齿

轮减速电机与链传动、同步带传动或齿轮齿条传动相结合,构成自动门的驱动系统。

无论设计减速器或选用齿轮减速电机,计算自动门的受力情况、载荷分布情况和计算

传动装置的运动和动力参数都是必需的。
