Generalized methods of estimations of lubricants' influence on the tribotechnical characteristics of friction pair "steel-steel" on the four-ball machine

Chulkin S., Breki A., Soloviova I., Kaczyński R.

Acta Mechanica et Automatica

2010

Vol. 4, no. 4

5-8

This article is devoted to the development of generalized methods of estimations of lubricants influence on the tribotechnical characteristics of friction pair “steel-steel” and its usage for selection of the best lubricating material out of set of materials “Litol-24”produced by different manufacturers.

Research of base and alloyed oil MC-20 influence on the tribotechnical characteristics of roller bearings

Chulkin S., Breki A., Soloviova I., Radkevich M.

Acta Mechanica et Automatica

2009

Vol. 3, no. 4

21-23

This article is devoted to research of the influence of an oil additive "serpentinite” on to roller bearings friction behavior. In this article the influence of the additive Ťserpentiniteť on the roller bearings (208 series) friction behaviour is considered. It has been established that the serpentinite addition to the oil MC-20 allowed to reduce friction losses at the start-up of the mechanism 15-20% in comparison with the base oil.
