Bearing industry commonly used classification ( 3)

Locomotive vehicles bearing railway line of bearing refers to electric locomotive and car bearing. Electric locomotive axle bearing contains on end bearing, traction motor bearing, gear bearing, bearing power system and refrigeration system bearing such as varied, but the car axle bearing mainly on end bearing, passenger axle end with a short cylindrical roller bearing, large cargo axle end key using tapered roller bearing, the car bearing type, structure, features, etc are similar to electric machine axle end bearing. Contemporary reducer reducer bearing can transport within the interior space in small high output power. This must be selected performance excellence rolling motor bearing. Apart from bearing capacity, effective design scheme of adjacent structure, RunHua and sealing into a spectrum and also the premise of bearing in the economic development of the layout. In order to consider this factor on the service life of bearing damage, you need to extend the service life of the calculated way to carry out the analysis. Because reducer design scheme and the way of gear meshing, basically all kinds of rolling bearing can be used to drive transmission field. Low cylindrical gear module type shaft often choose spherical roller bearings or tapered roller bearings to support. Under especially high speed ratio, the selection of cylindrical roller bearing to bear axial force and four-point touch ball bearing to bear axial force component is more suitable. In view of the intermediate shaft and output shaft, general fluctuations layout using spherical roller bearing. Low in conical gear module, in order to ensure the gear mesh, there must be a small diameter of axle correctly guide gap. Can choose the trunnion adjustable or matching installation of tapered roller bearing and angular contact bearings. Low turbocharged module vortex rod on the axial force can transfer according to the matching or adjustable taper roller bearings. In view of the vortex rod, gear and gear can adjust and small diameter of axle gap. Often used concave groove ball bearings or adjustable taper roller bearings. Low planetary gear box of planets round the general affairs or two row cylindrical roller bearing support, special circumstances can choose spherical roller bearing. For smaller planets round, can immediately install needle or vortex rod. , double twist on the gear transmission of mandrel operation immediately. In order to better ensure that the bearing capacity of the gear motor bearing arrangement and work life, ensure the strength of the cage curves of special regulations and process performance.
