Visual observations and torque measurements in the taylor vortex regime between eccentric rotating cylinders
367
SYSTEMATIC ABSTRACTS OF CURRENT LITERATURE hermeticity of combustion chambers, efftciency of purifying equipment, contamination and lubricating oil life. The equipment is simple and inexpensive and the test can be carried out by unskilled personnel. The method can be applied to oils from any closed system. 6.3. Testing of machine parts Shock Pulse Measurement of Bearings. P. A. Boto and I. Fernlund, Aircraff (12) (1970) 22-23; 2 figs.
Eng., 42
Extracts from papers presented at an SKF symposium describing a new technique of detecting damage to ball and roller bearings. With the shock pulse meter, the cause of damage and their effect on the bearing functions and machine performance can be scientifically studied. An Optical scaftIng.

R. F. Pywell, Tribology, 4 (1) (1971) 31-32; 3 figs., 1 ref. A technique is described which gives a satisfactory visual display of the piston ring without having to get close to the engine. The television technique combines the advantages of remote viewing, instantaneous visual display and a permanent immediate record by means of video recording. Visual Observations and Torque Measurements in the Taylor Vortex Regime between Eccentric Rotating Cylinders. P. Castle, F. R. Mobbs and P. H. Markho, JOLT,
Ser. F, 93 (1) (1971) 121-129; 8 figs., 18 refs. Visual observations and torque measurements were used to investigate the instability of Taylor vortices in the flow between a stationary outer cylinder and an eccentric rotating inner cylinder. Instability can be detected by torque measurements giving critical Taylor numbers in agreement with visual observations.
Measurement of the Dynamical Characteristics of a Large Sleeve Bearing. P. G. Morton, JOLT, Ser. F, 93 (1) (1971)
143-150; 8 figs., 4 mfs. The design and operation of a rig capable of measuring the dynamic oil-film characteristics for bearings up to 28 in. diameter running at speeds up to 4ooo r.p.m. is described. It is shown that predictions based on current theory considerably under-estimate the stability and overestimate the stiffness of the test bearing.
Measurement of Elastobydrodynamic Thicknec8 aad Wear in a Ball Bearing Strain Gauge Method. D. R. Meyer and C. C. Wilson, JOLT, 93 (2) (1971) 224-230; 14 figs., 2 tables,
Oil-film by the Ser. F,
9 refs. A simple method of measuring elastohydrodynamic oil-film thickness and wear in a ball bearing, using only a preloaded bearing and a strain gauge, is presented. Measured lubricant film thickness as a function of bearing speed for several different oils are given and compared to theoretical values. Wear data are also presented. Wear, 19 (1972) 355-367
