Abstract

Lip seals are widely used tribological machine elements with applications in manufacturing, oil, gas, aerospace, transport, and power industries. Their function is to separate fluids between two regions that share a common moving boundary. This paper sets out to investigate in detail the impact of operating a seal in various states of misalignment. A sophisticated seal test apparatus, compliant with ISO 6194-1:1982 has been developed. It allows precise states of misalignment between the shaft and seal centres to be set and enables the measurement of a range of variables including friction torque, leakage rate and temperature to characterise the performance of the seal. The paper will present measurements of these parameters as a function of speed and shaft eccentricity and discuss the implications of this data on the operating limits of seals.
