New test for oil evaluation in textile spindles. A.K. Mehta et al. Lubric. Engng., July 1997, 53(7), 19--25.
Development of a Textile Spindle oil Test Rig known as TESTER is described. It measures frictional force in high speed textile spindles and uses the actual bolster of a textile spindle supported on an air bearing and a one-eighth inch steel ball. An improvised air turbine runs the spindle at 15 000 rpm. The spindle blade and bolster assembly and the design of the test rig are described and illustrated. Laboratory tests and field trials are discussed and results show that TESTER successfully evaluates the very low frictional force existing in a high speed mill textile spindle. Good correlation between laboratory and field results is reported. 2 refs.
