Idler on Excavator
The excavator guide wheel, which is also called idler, is used to guide the track to rotate correctly to prevent it from deviation and derailment. Most excavators also act as rollers. This can increase the contact area between the track and the ground and reduce the grounding specific pressure. The wheel surface of the idler supports the smooth surface. There is a retaining arm ring in the middle as a guide, and the ring surfaces on both sides support the rail chain.
The Idler Wheel
In order to make the idler wheel of excavator work and prolong its service life, the radial runout of the wheel surface to the center hole shall be less than or equal to 3mm, and it shall be correctly aligned during installation.
The Idlers
The idlers of excavator adopts the box structure cast by resin sand process, with the appearance quality of the wheel body and reasonable mechanical structure performance; The matrix is normalized to obtain good impact resistance; And rail surface medium frequency induction quenching heat treatment, the surface hardness reaches hrc48-54, and the depth of 6mm is not lower than hrc46. It has wear resistance under bad working conditions.
