General:

The track roller is one of the traveling mechanism (four kinds of rollers 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 is also used to restrict track shoe assy and prevent lateral slippage. The track roller can be divided into single flange and double flange track roller.


Structure

The track roller is composed of roller body, roller shaft, shaft sleeve, sealing ring, end cover and other related parts.


Color

Bulldozer track roller surface is generally yellow paint.


Material and technology

The roller body material of track 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 support roller shaft requires high, which generally need CNC machine tools. 40Mn2 is in the majority with the material of track roller, after processing, it also needed to carry out quenching heat treatment, hardness up to HRC42.


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 track roller oil leakage.


Production:

Bulldozer single flange track roller also called bulldozer single flange bottom roller and bulldozer single flange lower roller is composition of two pieces of forged semi-roller and the roller body is welded by CO2 automatic welding.
