Ferrofluid lubrication in step bearing with two steps

Abstract

A study of step bearing lubricated with a ferrofluid was made in this paper. Shah and Bhat considered the term μ₀M(∂H/∂x) of ferrofluid as lubricant. The present paper discusses the problem with the modified term as μ₀M (∂H/∂x)+(16πμ₀r³χM)/(9(l+2)³)(∂H/∂x) of ferrofluid which incorporates more properties of ferrofluids. Expressions for pressure under the two steps and load carrying capacity were obtained. It was observed that the use of ferrofluid increases the load capacity of the bearing. Also load capacity become more when the length of the first step was taken less.
