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.
同時に, 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, and at the same time, 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.中国製トラックローラー manufacturers provide a variety of track rollers,please take a look and get to know track rollers more.
How do track rollers work?
クローラー回転掘削リグの主な耐荷重構造コンポーネントとして, 特に大トン数のクローラーロータリー掘削リグでは, 履帯の設計と製造の品質は、掘削リグ全体の安全性に直接関係します。. クローラー回転掘削リグの作業条件は複雑です. 特殊な巻き上げ条件またはブーム条件の場合, 軌道輪の一部のみに応力がかかる. したがって, 軌道輪の配置は中央が疎で、端が密になっています。. クローラーの要求を満たすため、回転掘削装置の重量は徐々に増加します。, 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. 脱線を防ぐために, 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: 耐摩耗性リム, reliable bearing seals, そして低い転がり抵抗.
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 (レールリンク) 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, 等.
