Description

一种自动扶梯曳引装置
技术领域:
本实用新型涉及汽车轮毂轴承技术领域,更具体地说涉及一种一种自动扶梯曳引装置。
背景技术
如图1、2所示,自动扶梯常规的驱动***是由一台减速电动机A1通过传动齿轮A2、链条A3传递动力,传动轴A4带动梯级曳引轮A5使得梯级可以上下运行,实现了运输乘客的功能。这种驱动方式通常要拥有较大的机房面积,同时因为是链条传动,有比较大的噪音产生。
实用新型内容
本实用新型的目的就是针对现有技术之不足,而提供一种自动扶梯曳引装置,它节省了机房面积,减少了传动装置,节省了生产成本,降低了机械噪音。
本实用新型的技术解决措施如下:
一种自动扶梯曳引装置,包括自动扶梯的梯级曳引轮,梯级曳引轮的传动轴固定在步进电机的转轴上,步进电机由变频器供电。
所述变频器与步进电机固定在一起,变频器和步进电机固定在自动扶梯的桁架上。
本实用新型的有益效果在于:
1、由于它将步进电机和变频器固定在自动扶梯的桁架上,无需单独在自动扶梯的桁架以外固定电机,所以节省了机房的面积。
2、由于它不用电机通过传动齿轮和链条带动传动轴,所以减少了传动部件,节省了生产成本,同时避免了传动齿轮和链条传动时发出的噪音。
附图说明:
图1为现有技术的结构示意图;
图2为现有技术中的梯级曳引轮传动结构示意图;
图3为本实用新型的结构示意图;
图4为本实用新型中的梯级曳引轮传动结构示意图。
图3、4中:1、梯级曳引轮;2、传动轴;3、步进电机;4、变频器;5、自动扶梯的桁架。
具体实施方式:
实施例:见图3、4所示,一种自动扶梯曳引装置,包括自动扶梯的梯级曳引轮1,梯级曳引轮1的传动轴2固定在步进电机3的转轴上,步进电机3由变频器4供电。
所述变频器4与步进电机3固定在一起,变频器4和步进电机3固定在自动扶梯的桁架5上。
工作原理:见图4所示,由于它将步进电机3和变频器4固定在自动扶梯的桁架5上,无需象现有技术中那样,见图2所示,单独在自动扶梯的桁架以外固定电机A1,所以节省了机房的面积。
由于它象现有技术中那样,使用电机A1通过传动齿轮A2和链条A3带动传动轴,所以减少了传动部件,节省了生产成本,同时避免了传动齿轮和链条传动时发出的噪音。

Claims (2)
