The four wheels refer to: rollers, drive wheels, idlers, and carrier pulleys. One belt refers to the tracks. As the name suggests, the rollers act as support and are located between the lower surface of the left/right beam of the chassis frame and the track. According to the tonnage of the excavator, there are usually 5-10 on one side. The driving wheel plays the role of driving the track, which is fixed on the travel motor, and the drive of the travel motor is transmitted to the track through the gear structure, usually one on each travel motor. The idlers act as guides the tracks, located at the opposite end of the drive wheels, usually two per excavator. The carrier roller plays the role of holding up the track, and according to the tonnage of the excavator, there are usually 1-2 carrier rollers on one side.
Our products are according to the standard of OEM to manufacture.
Idlers are used to guide the track around correctly and prevent it from mistracking and deviating. The idlers of most hydraulic excavators also play the role of rollers, which can increase the contact area of the track to the ground and reduce the specific pressure of grounding. The wheel face of the idler is made smooth, with shoulder rings in the middle for guidance, and the rings on both sides to support the rail chain. The smaller the distance between the idler and the nearest roller, the better the guidance. The idler is usually cast and quenched and tempered with 40, 45 steel or 35Mn steel, and the hardness is HB230~270.
