  • Taper Land Journal Bearing - Dyrobes

    2017-2-19 · The taper land journal bearing is commonly used in locomotive turbocharger application. The leading convergent area of the lobe is cut by a taper arc to increase the convergent area. Normally, there are dams at both sides of the taper. There are some redundant inputs in the data sheet, however, these are entered as reference.

    In the late 1960s, the technique of under-race lubrication was applied to tapered roller-bearings, that is, to lubricate and cool the critical cone-rib/roller-end contact. A tapered roller-bearing with cone-rib and jet lubrication, is shown schematically in Fig. 7.19. Under-race lubrication is quite successful in reducing inner-race temperatures.
