  4. 2. Grease lubrication mechanisms in bearing seals

    Author : Pieter Baart; Richard F. Salant; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : Rolling bearings contain seals to keep lubricant inside and contaminants outside the bearing system. These systems are often lubricated with grease; the grease acts as a lubricant for the bearing and seal and improves the sealing efficiency. In this thesis, the influence of lubricating grease on bearing seal performance is studied. READ MORE

  5. 3. Bearing lubrication of refrigeration screw compressors

    Author : Roger Tuomas; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : The bearings in a modern refrigeration screw compressor are lubricated with a mixture of oil and refrigerant. However, little or no published bearing life data is available for the new generation non-chlorinated refrigerants. READ MORE

  6. 4. Rolling bearing lubrication at low temperature

    Author : Victoria Wikström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : Problems connected with rolling bearings at low temperatures are high starting and running friction, concerns about the presence of a lubricating film and the degree of roller slip at low-temperature start-up. Also, questions have been raised whether the high shear stresses in a grease sheared at low temperature could cause thickener degradation. READ MORE

  7. 5. Design, testing and analysis of journal bearings for construction equipment

    Author : Henrik Strand; Sören Andersson; Arto Lehtovaara; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Contact Mechanics; Finite Element; Grease; Journal Bearing; Lubrication; Replica Technique; Test Apparatus; Tribology; Wear; Mechanical manufacturing engineering; Mekanisk tillverkningsteknik;

    Abstract : Grease-lubricated journal bearings present a common challenge for construction equipment manufacturers in the world. The common design methodology is based on empirical data and has worked very well historically because the market and governments have accepted that bearings in construction equipment need frequent lubrication and exchange of worn parts.
