Production description

The power of the hydraulic excavator engine is transmitted to the crawler through the driving motor and the excavator drive sprocket,which requires that the excavator undercarriage sprocket mesh with the track chain of the crawler correctly and smoothly. And the crawler can mesh well when it is elongated due to the wear of the track pins and track bushes.

Qulity control procedures

1. When raw material come inside our factory,we need to test the material composition first.

2. We need to analyze the composition of the first furnace of the steel liquid every day.

3. After several pcs of parts are heattreated, we need to check the hardness before all to be done to guarantee the hardness.

4. Our inspectors will check the sizes when parts are being machined and parts are being assembled.

Our excavator drive sprocket are applieable to below models:

What are the differences between the friction-welded track roller and the traditional type of track roller?

1. Friction-welding track roller is better in the wear-resistance and has longer working lifetime.

2. Consumption of material
For traditional track roller, the roller bodies are connected by the welding rod.
For friction-welding track roller, the roller bodies are connected by the friction between roller bodies.Friction part of roller will be added more material to make sure roller is conformed to the standard size after friction-welding.

3. Interior parts
For traditional track roller, the welding is done after two processes of fine machining, therefore the requirement to the size of interior parts is not that severe.
For friction-welding track roller, after the welding, there is one more fine machinning with concentric locating to make sure the conformity of inner sizes.And for which, the requirement to the size of interior parts is severe.Interior parts for friction-welding track roller are with higher standard.

4. Differences on the manufacturing processes
