Tribological behaviors of the water-lubricated rubber bearings under different lubricated conditions

Abstract

Purpose This study aims to evaluate the tribological behavior of water-lubricated rubber bearings sliding against stainless steel under different lubricate conditions. Design/methodology/approach The water-lubricated rubber bearings under various normal loads and sliding speeds were carried out on the ring-block friction test, and the wear morphology is test conducted by using scanning electron microscope. Findings The results indicate that the surface of water-lubricated rubber bearings has a more alternative friction coefficient and wear rate under seawater than other lubricate conditions. The seawater not only acts as a lubricating medium but also brings microstructure while corroding the rubber interface, thereby further enhancing the lubricating effect and storing abrasive debris. Originality/value In this paper, tribological properties of the water-lubricated rubber bearing on ring-block friction test has been investigated. Water-lubricated rubber bearing was carried out on various lubricate conditions, and the friction coefficient, wear rate and worn surface were analyzed. Also, the effects of sliding speeds were investigated. Peer review The peer review history for this article is available at: https://publons.com/publon/10.1108/ILT-06-2020-0204/

A review of advances in tribology in 2020–2021

“…Xiao et al [254] pointed that the surface of waterlubricated rubber bearings has a more alternative friction coefficient and wear rate under seawater than in other lubrication conditions. The seawater not only acts as a lubricating medium but also brings microstructure while corroding the rubber interface, thereby further enhancing the lubricating effect and storing abrasive debris.…”

Poly(N-isopropylacrylamide) Microgel Lubricants with High Friction Sensitivity

“…Water-based lubricants are widely used in bearings and seals that operate in aqueous environments. 1 Due to growing environmental concerns, attempts have been made in recent years to replace traditional oil-based lubricants with environmentally friendly water-based lubricants. 2,3 However, compared with lubricating oils, the low viscosity and poor filmforming ability of water severely limit the performance and dependability of water lubrication systems.…”

“…Water-based lubricants are widely used in bearings and seals that operate in aqueous environments . Due to growing environmental concerns, attempts have been made in recent years to replace traditional oil-based lubricants with environmentally friendly water-based lubricants. , However, compared with lubricating oils, the low viscosity and poor film-forming ability of water severely limit the performance and dependability of water lubrication systems. , To solve these problems, water-soluble oils, emulsions, ionic liquids, and nanomaterials are widely used as additives in water-based lubricants. − In addition, carbon-based solid lubricating coatings, such as diamond-like carbon (DLC), silicon-incorporated DLC (Si-DLC), and various metal-doped DLC (Me-DLC), have great potential in water lubrication systems and could effectively solve issues of high friction, high wear, cavitation, and corrosion .…”

Experimental Investigation of the Performance of SBR and RSS Materials as a Sliding Bearing Element

“…Prominent studies on the subject in the literature are as follows: Liu et al presented a new water-lubricated rubber bearing model for vibrating operations [1]. Ixiao et al examined the tribological behaviour of water-lubricated rubber bearings sliding against stainless steel [2]. Zhou et al investigated the straight-groove or spiral-channel Stribeck curve of WLRB with NR material in a comparison experiment using the rotational speed and external load as variables and found that the friction coefficient of straight-groove WLRB decreased with an increase in the load over the entire speed range [3].…”
