45Axle box roller bearingsof series 120's three-phase current locomotiveThe frame is supported by coil springs and spring seatswhich are integrated in the bearing housing. Thespring seats are arranged at different heights. The bearingis guided by an arm on each side which is linkeddiagonally to the housing. The arms are supported byelastic damping springs.Technical dataVehicle weight: 84,000 kgNumber of wheelsets: 4Wheelset weight: 2,250 kgAxle load: 22,000 kgSupplementary factor f z = 1.5The locomotive reaches top travelling speeds up to200 km/h.Bearing selectionPlease refer to example number 42 to determine theequivalent dynamic load P.Cylindrical roller bearings of the type NJ and NJPwith the dimensions 180 x 320 x 75 mm are mounted.Dynamic load rating of one bearing: C = 735 kN. Theouter and inner rings of both bearings are separated byspacer rings. The inner spacer ring is 2 mm wider thanthat of the outer rings.The axial clearance which arises thereby, is necessary tocompensate for bogie production tolerances. The bearingcan always be mounted without preload.Machining tolerancesThe bearing inner rings have circumferential load andare therefore given a tight fit: Journals to p6. The housingmaterial, an aluminium cast alloy, has a greater coefficientof expansion than cast steel which is why thetolerance field J7 was selected and not the housing toleranceH7 usually taken for cast steel housings.Bearing clearanceDue to the tight fit the bearing inner rings expand; theradial clearance becomes smaller. The outer ring iscooled more than the inner ring by the wind resistanceduring travel which leads to a further reduction ofclearance. For this reason bearings with increasedradial clearance C4 have been selected.Lubrication, sealingA lithium soap base grease is used for lubrication. Onthe wheel side the bearing is sealed by a two-web labyrinthseal. A V ring seal protects from contaminants onthe opposite side.45: Axle box roller bearings of series 120's three-phase current locomotiveFAG 66
