Sažetak
The plain bearings are often used due to their compact dimensions and low cost. Their frictional and wear properties are affected by a number of parameters ; load, sliding velocity, temperature, and surface roughness, among others. In this article, the authors have experimentally investigated the influence of clearance size on the friction and wear in composite plain bearings. An experimental rig was designed to enable testing of plain bearings in working conditions similar to ones encountered throughout the exploitation. Two load levels, two lubrication types, and four clearance levels were varied, resulting in 48 experiments since each was replicated two times. The friction coefficient and bearing temperature were measured during the experiment, while the material loss and change in surface roughness were determined post- experiment. The results have shown that clearance affects the friction in both the dry running specimens and specimens lubricated using a solid lubricant (polytetrafluoroethylene).
