The carrier roller is one of the traveling mechanism (two kinds of track rollers, carrier roller, idler and track shoe assy)on the chassis of track type construction machinery. Its main function is to support the weight of excavator and bulldozer and make the track shoe assy move along the roller. It also can restrict track shoe assy and prevent lateral slippage.
The carrier roller is composed of roller body, roller shaft, shaft sleeve, sealing ring, end cover and other related parts.
Bulldozer carrier roller surface is generally yellow paint.
Material and technology
The roller body material of carrier roller is generally 50Mn, 40Mn2 or other materials. The main process is casting or forging, mechanical processing, and then heat treatment. The hardness of the roller surface after quenching should reach HRC45~52, so as to increase the wear resistance of the roller surface.
The machining precision of carrier roller shaft requires high, which generally need CNC machine tools. 40Mn2 is in the majority with the material of carrier roller, after processing, it also needed to carry out quenching heat treatment, hardness up to HRC42.
What is a roller?
The roller, which is an important part of the belt conveyor, has many kinds and large quantities, and can support the conveyor belt and the weight of the material. It accounts for 35% of the total cost of a belt conveyor, which produces more than 70% resistance, so the quality of the roller is particularly important. It has two kinds of steel and plastic.
Problems and analysis
A. Roller body wear. It is attributed to unqualified steel or the hardness of the material during heat treatment is low and the wear resistance is insufficient;
B. Oil leakage. The roller shaft shall be keep rotating, the roller body needs to be lubricated. However, if the sealing ring is not qualified, it is easy to produce oil leakage. Therefore, it is easy to wear between the shaft and the shaft sleeve without lubrication, which makes the product unable to be used.
The reasons for oil leakage are as follows: 1. floating oil seal unqualified 2. Sleeve roundness is not enough 3. Shaft gloss is not enough 4. Gear oil is not up to standard 5. Machining dimensional tolerance .These problems will cause the carrier roller oil leakage.
