China Factory Undercarriage Parts Tracking Roller EX400 EX400-1EX450 Hitachi Excavator Top Roller
Structural form and working principle of supporting wheels
At present, there are two types of support wheel structures for track engineering machinery at home and abroad: straight shaft and convex shoulder shaft. According to the design requirements, it should be selected for excavation with simple structure, good craftsmanship, few parts, but slightly poor axial force resistance
Excavator type operating conditions. The supporting wheel is used to support the gravity of the machine, and it rolls on the track link or track guide plate. Therefore, it is used to clamp the track and prevent it from slipping and derailing laterally. And when turning, drive the track to slide sideways on the ground. Support wheels sometimes work in muddy water and withstand significant impact loads. Therefore, it is required to have reliable sealing, wear-resistant wheel flanges, and low rolling resistance
