E. Koc et Cj. Hooke, INVESTIGATION INTO THE EFFECTS OF ORIFICE SIZE, OFFSET AND OVERCLAMP RATIO ON THE LUBRICATION OF SLIPPER BEARINGS, Tribology international, 29(4), 1996, pp. 299-305
This paper represents the results of an experimental investigation of
the performance of hydrostatic slipper bearings in axial piston pumps
and motors. The effect of clamping ratio, offset loading and orifice s
ize on the behaviour of overclamped and underclamped slippers is outli
ned. It is shown that the slippers run satisfactorily with no orifice
and have their greatest resistance to tilting couples and to minimum f
ilm thickness. The underclamped slippers and slippers with larger orif
ice diameter run with relatively larger clearance and tilt than those
of overclamped slippers with no orifice. Cavitation tends to affect th
e slippers, especially at the rear of the slipper. Ineffective flood l
ubrication may be the cause and oil jet pressure must be maintained to
prevent oil starvation. Copyright (C) 1996 Elsevier Science Ltd
