1. Elongation failure
When the load exceeds the yield limit, the plastic deformation occurs in the short pitch precision roller chain for transmission, and the chain plate and chain plate hole are elongated, resulting in the chain can not work normally.
2. Fatigue damage
The tension of the force side and non force side of the short pitch precision roller chain for transmission is different. Under the action of variable load, after repeated cycles, the chain plate will appear micro cracks, and gradually expand, resulting in fatigue damage, such as fracture, and fatigue pitting corrosion will occur on the roller surface. If the lubrication is normal, fatigue damage is often the main factor limiting the bearing capacity and life of the chain.
3. Chain wear
Wear often occurs between the pin and the sleeve, making the gap larger and the chain longer, until the chain can not accurately mesh with the sprocket, or can not maintain the correct distance and timing. Sometimes the wear between roller and sleeve or between chain plate and guide plate can also lead to chain failure.
4. Gluing
In the case of insufficient or inappropriate lubricant, when high speed or heavy load occurs, it is difficult to form a complete lubricating oil film between the pin and the sleeve, and the direct contact between metals leads to gluing or welding. Gluing makes the relative movement between pin and sleeve impossible, which limits the transmission speed of precision roller chain with short pitch.
