Abstract

A run of experimental tests have been undertaken for investigated various types of ring. Where the ring is splitt up into two pads, also, a ring is split up into four pads respectively. The effect of using different pads is then evaluated and the influence of different factors on performance is discussed under steady applied load conditions. 
Performance factors are described in terms of, supply pressure, friction torque oil flow rate, inlet-outlet temperature and ring speed. Results are reached on the relative credits of each control variable case. A reduction in friction torque ranges between 25% and 30% is obtained at speed of 1330 r.p.m. to 1700 r.p.m. and over respectively. It is established that the number of pads is an important factor in reducing friction torque of floating ring bearing. It was found experimentally that four pads bearing reached a reduction of 25% in the friction torque at constant pressure, temperature, load and viscosity.
