Introduction of Sprockets
Large sprockets as well as mini excavator sprockets are molded or forged first, then processed with a special heat treatment. Steel becomes brittle during the hardening process if it lacks sufficient amounts of carbon. If only the surface is hardened, the sprocket or segment will wear out quickly. As a result, the sprocket teeth are hardened using induction hardening. Our segments are precision-forged, finished, and hardened under special conditions.
Excavator drive sprockets and segments, also known as cogwheels in the industry, run between the excavator or bulldozer chain links. Furthermore, this undercarriage component runs over the bushing that connects two chain links. The cogwheel is installed around the machine's drive gear and serves only to drive the chain, so it bears no weight.
THE DISTINCTION BETWEEN SPROCKETS AND SECTIONS
Sprockets are metal cogwheels made up of a metal inner ring with bolt holes or a compression hub and a gear ring combined into one unit. Sprockets are typically used on excavators and can be screwed on directly or pressed onto the machine's drive hub.
Segments, like sprockets, are made up of a metal inner ring with bolt holes and a gear ring. Unlike sprockets, segment groups are made up of individual segments that make up the sprocket for a bulldozer's undercarriage. This means that the segments can be swapped without having to dismantle the track link.
HOW CAN YOU IDENTIFY SPROCKET AND SEGMENT WEAR PATTERNS?
Sprockets and segments should always be aligned with the chain's pitch. If the sprocket or segment is worn, the points of the gear ring will become sharp. The movement between the pins and the bushings is the cause of this. Another prevalent wear pattern for sprockets and segments is lateral wear. This can be caused by worn chain guides, a twisted undercarriage, or poor front wheel guidance, among other problems. Hard material filtering between the bushings and the cogwheel, as well as poor alignment, might cause it. To alleviate wear caused by soil infiltration, we cut sand notches in our sprockets.
Because bulldozers undertake a lot of mobile work, oil-lubricated chains and segments are required. The cup between the segment points is where segment wear is most commonly found. The pitch will rise and the points of the segments will become sharp only when the oil-lubricated chain leaks. It is advisable to change the segments before the end of the cycle if the oil-lubricated chain does not leak; this allows the undercarriage to be utilized for a few hundred hours longer.
