ABG325导向轮 #200102476
导向轮用来引导履带正确绕转，防止其跑偏和越轨。
多数的挖掘机也同时起到了支重轮的作用。这样可以增加履带对地面的接触面积，减小接地比压。
导向轮的轮面制成光面，中间有挡臂环作为导向作用，两侧的环面则支撑轨链。
导向轮与最近的支重轮的距离越小，则导向性越好

he guide roller is used to guide the track to rotate correctly, preventing it from deviating and deviating from the track.
Most excavators also act as supporting wheels. This can increase the contact area of the track to the ground and reduce the ground specific pressure.
The wheel surface of the guide wheel is made into a smooth surface, with a retaining arm ring in the middle serving as a guide, and the ring surfaces on both sides support the rail chain.
The smaller the distance between the guide wheel and the nearest roller, the better the guidance
