The invention belongs to the technical field of mechanical transmission, particularly relates to a rope wheel mechanism, and provides the following scheme aiming at the problems that an existing spring reset type incomplete gear mechanism is prone to jamming, unbalanced in gear tooth load during working, large in occupied space and the like. The driven part is installed on the machine frame and moves relative to the machine frame, an energy storage part is further arranged between the driven part and the machine frame, the two ends of the energy storage part are connected with the driven part and the machine frame respectively, a flexible rope is used for replacing gear teeth to pull the driven part, and when the driven part cannot be reset to the correct position, tooth crest collision cannot happen, so that the situation that a mechanism is stuck or even equipment is damaged is avoided. Load is transmitted to the driving wheel through the rope all the time, the situation that the bearing capacity of a traditional spring reset type incomplete gear movement mechanism is weak at the beginning and the end of transmission is avoided, the rope is wound on the driving wheel in the working process, the driven part is driven by the rope, and the occupied space is smaller.
本发明属于机械传动技术领域,尤其是一种绳轮机构,针对现有的存在弹簧复位式不完全齿轮机构容易出现卡死,工作时轮齿负载不均衡,且占用空间大等问题,现提出如下方案,主动轮以单侧支承的方式转动安装于机架;从动件安装于机架,相对机架运动,从动件与机架间还设有蓄能件,蓄能件的两端分别与从动件和机架连接,用柔性的绳索取代轮齿拉动从动件,当从动件未能复位到正确位置时,也不会发生齿顶碰撞,导致机构的卡死,乃至损坏设备,负载始终通过绳索传递给主动轮,不存在像传统的弹簧复位式不完全齿轮运动机构在传动初始和结束时机构承载能力较弱的情况,工作时绳索收卷于主动轮上,并由绳索带动从动件,占用空间更少。
