description

The track roller is used to support the weight of the excavator, while rolling on the track (rail link) or the track surface of the track. It is also used to limit the track and prevent lateral slippage. When the excavator turns, the rollers force the track to slip on the ground.
The function of the track roller is to transmit the weight of the locomotive unit to the ground and roll on the track. In order to prevent derailment, the support rollers should also be able to prevent the crawler from causing lateral relative movement to it.
The support wheels often work in mud, water, ash, and sand, and are subject to strong impacts. The working conditions are extremely harsh and the rims are easy to wear. The requirements for the track rollers are: wear-resistant rims, reliable bearing seals, and low rolling resistance.
Problems
(1)Wheel body wear. The reason for this situation is that the steel used is unqualified or the hardness of the material during heat treatment is low, and the wear resistance is insufficient;
(2) Oil leakage. The bearing wheel shaft has been rotating through the shaft sleeve, and the wheel body needs to be lubricated by adding oil, but if the sealing ring is not good, it is easy to cause oil leakage, so that the shaft and the shaft sleeve are easy to wear without lubrication. The product cannot be used. The reasons for oil leakage are as follows: 1. Unqualified floating oil seal; 2. Insufficient roundness of the product bushing; 3. Insufficient luster of the support shaft; 4. Gear oil not up to standard; 5. Processing size tolerance and so on. The above-mentioned problems will cause oil leakage from the track roller.
