Roller adalah salah satu sabuk roda empat pada sasis mesin konstruksi yang dilacak. 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.
Pada saat yang sama, 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, dan pada saat yang sama, 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.Roller trek Cina manufacturers provide a variety of track rollers,please take a look and get to know track rollers more.
How do track rollers work?
Sebagai komponen struktural penahan beban utama rig pengeboran putar perayap, terutama pada rig pengeboran putar perayap bertonase besar, desain dan kualitas pembuatan track wheel berhubungan langsung dengan keselamatan rig pengeboran secara keseluruhan. Kondisi kerja rig pengeboran putar perayap sangat kompleks. Dalam beberapa kondisi pengangkatan khusus atau kondisi boom, hanya sebagian roda lintasan yang mengalami tekanan. Karena itu, susunan roda lintasannya jarang di bagian tengah dan padat di bagian ujungnya. Untuk memenuhi kebutuhan crawler, bobot rig pengeboran putar secara bertahap meningkat, 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. Untuk mencegah penggelinciran, 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: pelek tahan aus, reliable bearing seals, dan tahanan gelinding yang rendah.
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 (hubungan kereta api) 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, dll..
