几种斜楔机构的特性分析

Characteristic Analysis of Several Wedge Mechanisms

斜楔机构具有能改变构件的运动方向,改变力的方向以及增力和自锁的特点。将斜楔机构运用到矿井机械设备的制动装置中,一方面可以减小制动推力,另一方面可以改变构件的运动方向。同时利用斜楔机构具有自锁的特点,即使液压油出现泄漏现象,使得斜楔机构不能后退,从而也可以达到增力的作用。斜楔机构型式多种多样,通过改变斜楔机构的结构形式并且利用Adams对不同的斜楔机构进行自锁仿真分析可以得出其不仅可以实现自锁而且和普通斜楔机构相比较可以在不同程度上增大行程比。

The function of changing the moving direction of the member,changing the direction of the force,and increasing the force and self-locking was possessed by the wedge mechanism.The application of inclined wedge mechanism in the braking device of mine mechanical equipment can reduce the braking thrust on the one hand and change the moving direction of components on the other hand.At the same time,the inclined wedge mechanism has the characteristics of self-locking,Even if the leakage of hydraulic oil occurs,the wedge mechanism can not be retreated,so the force can be increased.There are many types of wedge mechanism,by changing the structure of wedge mechanism and using Adams to simulate and analyze the self-locking of different wedge mechanisms,it can be concluded that the wedge mechanism can not only achieve self-locking,but also increase the stroke ratio in varying degrees compared with ordinary wedge mechanism.
