Abstract
A ball-disc traction test rig is improved through the development of a lubricant traction measurement system, consisting of a resonance force sensitive quartz sensor, a circuit of the sensor and a rigid bracket jointed by a frictionless hinge. The traction coefficients of a kind of domestic lubricating oil were measured at various normal loads, rolling velocities, lubricant inlet temperatures and slide-to-roll ratios on a ball-disc traction test rig equipped with this traction measurement system. The results show that the traction test curve is smooth and the data enjoy a good accuracy, which indicates that the design of the lubricant traction measurement system is reasonable and the precision of the system is high, especially, at high temperature, high rolling speed and small slide-to-roll ratio.
