Abstract
Hydrocarbon grease is used to lubricate and protect wire rope usually, but there are some problems have been found during lubricating process, such as high and low temperature working conditions resistance and waterproof performance and so on, in this paper we try to employ lithium grease to lubricate wire rope, according to the experiments, it comes a conclusion that lithium grease has the advantages which hydrocarbon grease doesn’t have by comparing the performance of both, the properties of wire rope grease have been successfully improved by adding some lithium grease, and the percentage of addition is a key factor.
Highlights
Wire rope is one of the key factors for usual operation of many lifting equipment, which is widely used in mining, forestry, industrial production, agriculture, transportation and housing construction [1]
The results show that the lithium grease had excellent performance in the wire rope grease performance test
It comes the conclusion from our tentative experiment of using lithium grease to lubricate wire rope as the following: compared with hydrocarbon grease, lithium based grease has good performance at high temperature, and shows better anti-brittle performance at low temperature, and the lithium grease performed well in the slid test
Summary
Wire rope is one of the key factors for usual operation of many lifting equipment, which is widely used in mining, forestry, industrial production, agriculture, transportation and housing construction [1]. Dust and corrosion, water washing and heavy loads are common in these working environments, and many authors believe that proper lubrication can improve the service life of the wire rope [2]. The individual wires and strands rub against each other in order to adjust themselves to the curvature of the rope wound around the core. Some unique requirements for the selection of wire rope grease are put forward on account of the extremely weather, rain and snow, wind and sand, corrosive gas and so on in the working environment [4]. Lubricating performance is essential to the motional wire rope, lubrication prevents to wear on the individual wires and strands [5, 6]. In this paper, we tried to add lithium grease to hydrocarbon grease and want to improve the performance of wire rope grease
