The guide wheel is located at the front of the X frame and consists of the guide wheel and the tension spring installed inside the X frame. During operation and walking, keep the guide wheel in front, so as to avoid abnormal wear of the chain rail. The tension spring can also absorb the impact from the pothole road ahead and reduce wear.
The guide wheel of chassis accessories is used to guide the correct rotation of the track and prevent its deviation and deviation from the track. Most excavators also act as road rollers. This can increase the contact area between the track and the ground and reduce the ground specific pressure. The wheel surface of the guide wheel is smooth, the middle arm ring plays a guiding role, and the ring surfaces on both sides support the guide rail chain. The smaller the distance between the guide wheel and the nearest roller, the better the guide.
Guide wheel material: 40,50 steel, or 35Mn, cast, quenched and tempered, hardness HB230-270.
In order to make the guide wheel work normally and extend its service life, the radial runout of the center hole of the wheel set should be less than or equal to 3MM, and it should be correctly aligned during installation.lmportaciones alibaba｜Bulldozer Idler Made in China
