Abstract

一种轮椅用蜗杆传动机构，涉及轮椅驱动技术领域，它包括驱动电机(1)、驱动弹簧(6)、传动齿轮(7)，人们使用本发明设计的轮椅，在使用之前人们通过转动调节把手(15)；通过调节把手(15)带动调节U形环(13)转动；调节U形环(13)带动调节螺纹轮(14)转动；调节螺纹轮(14)转动就会使得调节螺纹轮(14)沿着调节螺纹轮(14)轴线移动，即可以通过调节调节把手(15)来控制驱动弹簧(6)的初始弹性性能。进而控制驱动弹簧(6)所能传递的最大扭矩；在人们调节好螺纹的初始弹性性能时；控制驱动电机(1)开始工作；驱动电机(1)带动传动轴(5)转动；传动轴(5)带动两个弹簧固定圆盘(8)转动；两个弹簧固定圆盘(8)带动驱动弹簧(6)转动；驱动弹簧(6)转动带动传动齿轮(7)转动；传动齿轮(7)带动齿轮轴(11)转动；通过齿轮轴(11)旋转可以带动轮椅工作，通过第一调节齿牙（16）和第二调节齿牙（23）在传动轴（5）转动时对驱动弹簧(6)的束缚力调节驱动弹簧(6)传递的扭矩。
