“…While investigating the influence of material parameters on the erosive wear behaviour of various brittle materials such as metals and glass, Wiederhorn and Hockey [16] developed the wear equation based on dimensional analysis approach. Burr and Marshek [15] analysed the abrasive wear behaviour of elastomeric O-ring materials of the rolling cutter rock bit using dimensional analysis technique and correlated the wear volume with the friction force, specimen load, sliding distance and breaking strength of the materials.…”

“…Similarly few papers are reported on the dimensional analysis of wear behaviour of the polymers in adhesive wear mode [13,14] and in abrasive wear mode [15]. Wiederhorn and Hockey [16] on the other hand analysed the erosive wear behaviour of brittle materials using this dimensional analysis method.…”

Abrasive wear behaviour of a series of polyamides (PAs) with different methylene to amide ratio (CH 2 /CONH) was analysed using Buckingham's dimensional analysis method and efforts for quantifying the contribution of the material properties towards the abrasive wear performance were also made. In order to calculate the wear coefficient (K), the data based on the experimental wear volume, operating parameters and the material properties were fitted into the non-linear wear equation. The non-linear wear equation was derived based on pi theorem using the dimensional analysis technique. The wear coefficient K decreased as load and abrasive grit size were increased. The theoretical and experimental wear volume correlated well in most of the cases. Among the selected material properties, the fracture stress (r * ) and the critical crack length (C * ) were found to be the most important parameters, which controlled the abrasive wear behaviour of PAs.

“…The life of conventional elastomeric seals is limited, however, by eventual loss of radial compression, with abrasive wear at the sealing interface the primary failure mechanism. 1,2 This loss of radial compression permits abrasive drilling fluid to intrude into the bearing system and results in bit failure. This wear mechanism has been confirmed over the years by analysis of bits returned from the field by Dresser Industries/Security Div.…”

This paper presents field performance results for a new type of bearing seal for rock bits. The new seal design is found to be effective in significantly reducing abrasive wear at the sealing interface by virtue of its unique geometry that simultaneously introduces a hydrodynamic lubricant film and prevents the ingress of abrasives at the sealing interface. This has resulted in longer seal life and overall improvements in the rock-bit performances by a significant reduction in early seal failures.

Keywords IN TRO D UC TI0 NA test method and a testing machine for evaluating the wear of lip seals for pneumatic cylinders are presented. The method and the machine have been evaluated with tests on different types of seals for cylinders with a 50 mm bore. Three levels of lubrication condition were examined: dry, with a film of grease, and with an optimum amount of grease. Differences were noted both between these conditions of lubrication, and between types of seal. 0 Leaf Coppin 1997
