The sprockets are first molded or forged, then machined and subjected to special heat treatment. If there is not enough carbon in the steel, it will become brittle during hardening. If it's just surface hardening, then sprockets or sprockets can wear out very quickly over time. Therefore, the sprocket teeth are hardened by induction hardening. Pingtai section passes precision forging, finishing and hardening under special conditio
Like the sprocket, the section also includes a metal inner ring with bolt holes and a gear ring. Unlike the sprocket, the segment group consists of individual segments of the sprocket that make up the bulldozer landing gear. This means that sections can be swapped without dismantling track connections.
A sprocket is a metal gear consisting of a metal inner ring with bolt holes or a compression hub and a gear ring. Sprockets can be screwed on directly or pressed on the driving hub of the machine, usually used in excavators.
Sometimes the machine's sprocket and segments are sharp, but the track link seems to be in reasonable condition. We are often asked if we still need to replace the sprockets. The only reason sprockets get pointed is because the chain pitch increases. Increased spacing creates more clearance between pin and bushing. As a result, the chain bushing no longer aligns with the hollow part of the sprocket. This can cause the sprocket to wear and become sharp at the tip. So never just change the sprocket. If it is necessary to replace the sprocket of the excavator with dry chain, the track chain joint should always be replaced.
Because the bulldozer does a lot of moving work, it requires oil-lubricated chains to be combined with segments. Segment wear usually occurs in the cup-shaped area between segment points. Only when the lubricating oil lubricates the chain leakage, the pitch will increase, at this point the chain segment will become sharp. If the oil-lubricated chain does not leak, it is best to replace the section before the end of the cycle; That will give the chassis a few hundred more hours.
Sprockets and chain links should always match the pitch of the chain. If the sprocket or blade is worn, the tip of the ring will become pointed. This is because there is a gap between the pin and the bushing. Another common wear pattern for sprockets and chain blades is lateral wear. This is caused by worn chain rails, twisted landing gear or poor front wheel steering. It can also be caused by hard material filtering between bushings and gears, or incorrect alignment. To limit wear caused by soil infiltration stuffing, we made sand troughs on sprockets.
