excavator Track Bottom Roller double track D20 roller track roller undercarriage
The types of supporting wheels used for combination track and integral or rubber track are different: the supporting wheels of combination track roll on the guide rail, while the supporting wheels of integral or rubber track roll on the track shoe.
There are two types of supporting wheels for combined track, as shown in Figure 1. One is a single flange, and the other is a double flange. The former is easy to manufacture; So it is more commonly used, and the latter is less commonly used. The purpose of having a flange is to prevent the track from moving laterally relative to it, in order to prevent derailment during turns. The height of the flange is usually 10-20 millimeters. In order to reduce friction between the wheel flange side and the guide rail side, the wheel flange side is often made into an inclined plane, with an inclined angle α= 20°~30°
