The roller is one of the four-wheel belts on the chassis of tracked construction machinery. Its main function is to support the weight of excavators and bulldozers to move the tracks along the wheels.Track rollers are the wheels on the excavator chassis around which the weight is distributed.
Al mismo tiempo, track roller also rely on their roller flange to clamp the chain track not to derail the track laterally, to ensure that the machinery moves in the direction of the track, y al mismo tiempo, track roller have a relatively small rolling resistance, and can complete the work in water or mud.
Track roller is a crucial part of an excavator.Rodillo de pista de China manufacturers provide a variety of track rollers,please take a look and get to know track rollers more.
How do track rollers work?
Como principal componente estructural de carga de las plataformas de perforación rotatorias sobre orugas, especialmente en plataformas de perforación rotativas sobre orugas de gran tonelaje, El diseño y la calidad de fabricación de las ruedas de oruga están directamente relacionados con la seguridad general de la plataforma de perforación.. Las condiciones de trabajo de las plataformas de perforación rotativas sobre orugas son complejas.. En algunas condiciones especiales de elevación o condiciones de pluma, sólo algunas de las ruedas de la oruga están estresadas. Por lo tanto, la disposición de las ruedas es escasa en el medio y densa en los extremos. Para cumplir con los requisitos de la oruga A medida que el peso de la plataforma de perforación rotativa aumenta gradualmente, the number and structural parameters of the track rollers increase accordingly.
The track rollers are installed at the bottom of the track frame and form a roll with the bottom surface of the track plate when walking.
Function of Track rollers
The function of the rollers is to transfer the weight of the locomotive set to the ground and roll it on the track. Para evitar el descarrilamiento, the roller also has to be able to prevent the track from moving laterally relative to it. Road rollers often work in muddy water and sandy soil and are subjected to strong impacts. The working conditions are extremely harsh and the wheel rims wear out easily. The requirements for road rollers are: llantas resistentes al desgaste, reliable bearing seals, y baja resistencia a la rodadura.
Characteristics of a good track roller
The excavator support wheel is one of the most important accessories of the excavator, it is used to support the weight of the excavator while rolling on the guide rails (enlaces ferroviarios) or track plate surface of the tracks, it is also used to restrain the tracks and prevent lateral slippage. The support wheel forces the tracks to slide on the ground as the excavator turns. The excavator support wheel is often in mud, water and dust, and is subjected to strong impacts, so it is required to be sealed reliably and the rim is wear-resistant.
Requirements for excavator supporting wheel:
- Wear-resistant wheel rim
- Reliable bearing seal
- Low rolling resistance, etc..
