Abstract

Tribotechnical and ecological evaluation of the friction pair FPM EМ-1/steel S235JR used in LTM braking devices was carried out. The analysis of the research results showed that in the range of contact pressures from 0.05 to 0.5 MPa, the wear of the friction lining is 1.5–2.5 times higher than the wear of the disk; the friction coefficient decreases from 0.91 to 0.43; the number of wear particles with diameters from 0.01 to 1.56 μm, which are the most dangerous for human health as they cause cardiovascular diseases, is about 94–98%; and the number of wear particles with diameters from 2.5 to 10 μm, which are associated with respiratory tract morbidity, does not exceed 6%.

起重运输机制动装置摩擦副的摩擦学和生态学评估

摘要

对用于LTM制动装置的FPMEМ-1/ S235JR摩擦副进行了摩擦技术和生态学评估。对研究结果的分析表明，在接触压力为0.05至0.5 MPa的范围内，摩擦衬片的磨损是盘的磨损的1.5-2.5倍；摩擦系数从0.91降低到0.43；直径在0.01到1.56μm之间的磨损颗粒的数量大约为94-98％，这对人类健康是最危险的，因为它们会导致心血管疾病。与呼吸道发病率有关的直径在2.5至10μm的磨损颗粒数量不超过6％。
