The pitting of the tooth surface of Industrial Sprocket often appears in the closed soft toothed surface drive with good lubrication. Generally, pitting-like pits appear near the root of the tooth. There are many reasons for pitting corrosion, including the following:
1. The tooth surface is subjected to multiple alternating stresses, resulting in contact fatigue cracks.
2. The joints are often single-toothed and have high contact stress.
3. The section line is pure rolling, the sliding speed near the section line is small, the oil film is not easy to form, the friction is large, and cracks are easy to occur.
4. Lubricating oil enters the crack, forming a closed high-pressure oil cavity, and the squeezing effect makes the crack expand.
The tooth surface of an industrial sprocket will damage the surface of the tooth profile, generate vibration shock and noise, cause the contact surface to decrease, and the transmission to be unstable, resulting in a reduction in the sprocket bearing capacity.
