Antifriction bearings & lubrication
Succinct refresher of bearing technology: different types of bearings according to the loads supported, hub units, tightness of bearings, bearing nomenclature.
Bearing lubrication: oil or grease? Modes of application of grease. Mechanism of the lubrication with grease. Choice of a grease according to the functioning conditions. Lubrication intervals and grease quantity to inject. Bearing life: influence of the grease and its cleanliness.
Lubrication of automotive hub units.
Bearing failures: identification of the different types of failures and root causes.
Other applications of greases than antifriction bearings
Technology of automotive transmissions: joints (RZEPPA, tripods). Grease for automotive transmissions.
Technology of couplings and universal joints and associated greases.
Gear greases: enclosed and open gears.
Exercises of grease definition and selection as a function of the running conditions.
Upon completion of the course, participants will be able to:
understand the main points on grease: structure, properties, production modes, testing methods and performance characterization, different types of greases and criteria for the choice according to the applications,
know the applications of grease other than bearings (gears, automotive and industrial transmissions, couplings),
recommend a bearing grease according to the operating conditions and to calculate the lubrication intervals and the life time,
recognize the bearing failures and identify the origins.
Ways & Means
Interactive exercises with the teacher for the determination of a bearing grease, the lubrication intervals, the lifetime calculation of bearings according to the operating conditions.
Interactive exercises of questions-answers between the participants using sets of play cards to synthetize the essential points of the lectures.
