FRICTION MODIFIER AND TRANSMISSION OIL - …

2011-2-3 · EVALUATION. As is apparent from the friction coefficient at each sliding velocity, each of the lubricating oil compositions of Examples 1 to 4 containing the friction modifier according to the invention gives a high friction coefficient at each sliding velocity which less varies in the range of 1 m/s to 0.025 m/s, and gives a high average friction coefficient.

Coefficient of Friction - an overview | ScienceDirect …

Coefficient of friction (COF) is a dimensionless number that is defined as the ratio between friction force and normal force (Eqn (2.1)).Materials with COF smaller than 0.1 are considered lubricous materials. COF depends on the nature of the materials and surface roughness.

Friction Reduction of Oil-Impregnated Sintered …

In this study, to reduce the friction of oil-impregnated sintered bearings, rounded-rectangle dimples are processed on the bearing surface and the bearing properties are examined. The dimpled bearings achieved lower friction than the flat bearings without dimple processing. To investigate the mechanism of friction reduction of the dimpled ...

Friction Science Experiment - The Teacher's Corner

Friction is a subject that I thought I knew a lot about, until I began to really look at it. Then I realized that the subject was a lot more complex than just observing how things rub together. Tribologists (scientists that study friction) divide friction into static and kinetic.

Friction and Lubrication - NIOS

For example: 1) While walking friction helps us. If we put oil on the floor, we will fall down due to slippery floor. We need friction to be able to walk. 2) It is commonly seen that in muddy area the wheel of a truck slips round and round because there is no friction between the tyres and ground. 3) Flour mill works because of friction between ...
