矿井多绳摩擦式提升机是利用钢丝绳和固定在卷筒上的摩擦衬垫之间的摩擦力传递动力,摩擦衬垫性能优劣直接影响提升机的提升能力及安全可靠性。研究不同摩擦衬垫的力学性能及其黏弹特性,并在摩擦磨损试验机上开展其摩擦学实验,研究摩擦衬垫在不同参数下耐磨损性能的变化规律,探讨耐磨性能与其基本力学性能及黏弹特性之间的关联关系。结果表明,材料磨损量与其弹性模量和抗压强度存在密切关系,弹性模量和抗压强度越大,磨损程度越小。
Mine multi-rope friction hoist is the use of wire rope and fixed friction in the reel liner between the frictional power transmission, the performance of friction linings directly affect the lift capacity and safety and reliability. The mechanical properties and viscoelastic properties of different friction linings were studied. The tribology experiments were carried out on the friction and wear testing machine to study the changing rules of the wear resistance of the friction linings under different parameters, and the relationship between the wear resistance and the basic mechanical properties And viscoelastic properties of the relationship between. The results show that there is a close relationship between material wear and its elastic modulus and compressive strength. The greater the elastic modulus and compressive strength, the less the wear.
