What is the transmission efficiency of plain bearings and rolling bearings?
The friction coefficient of plain bearing is 0.08~0.12, while the rolling friction coefficient is only 0.001~0.005; the rolling bearing of high transmission efficiency, less warm, therefore, can increase the cost of oil slick, smooth maintenance more convenient.
The oil film also has a certain vibration absorption capacity. But the starting friction resistance is larger.The coefficient of friction of rolling bearings is smaller than that of sliding bearings, and the transmission efficiency is high.
The efficiency of the sliding bearing is 0.92~0.96; the efficiency of the rolling bearing is 0.98~0.99.Sliding bearings (sliding, bearing) bearings that work under sliding friction. Plain bearings work smoothly, reliably and without noise. Under the condition of liquid lubrication, the sliding surface is separated by the lubricant without direct contact, and the friction loss and surface wear can be greatly reduced.
