It is attached to the final drive motor so that when the drive motor and the sprocket rotate as well. Its teeth then mesh with the links on the track and make the track move. Much like a sprocket on a bicycle catches the chain, causing the wheels to turn.
How to prevent wear?
One of the most important ways to prevent premature star wear is to check the track tension. Too much tension will wear the sprocket wheel teeth. Keeping the undercarriage clean is also important as the condition of the undercarriage can affect the tension on the tracks. Especially in cases of dried mud and debris.
Without a working excavator drive sprocket, the track drive will not be able to propel the machine. Drive sprockets must be replaced before it begins to wear the tracks or affect the performance of the final drive.
Signs of Sprocket Wear
The teeth on a drive sprocket are where you look for wear. They should be tall and flat at the end, not sharp or dished at the end. And the sprocket, and more specifically its teeth, begin to wear, its diameter becomes smaller. This causes what is known as a pitch mismatch, where the teeth on the sprocket no longer interact with the track links as effectively. This can accelerate the wear of the sprocket and reduce the efficiency of your equipment.
If your sprocket shows sign of excessive wear, then its time to replace it before it starts to cause abnormal track wear or begins to negatively affect the performance of your final drive motor.
