The bearing grease, oil lubrication, due to the lack of sufficient oil amount, in relative motion surface to produce between the bearing oil film bearing complete, only in the mixed friction condition, belonging to the non liquid sliding bearing. This kind of bearings are the main failure form of the wear and scuffing, followed by the crushing and pitting. Therefore, the bearing calculation criterion is maintenance, material and boundary of oil film bearing, bearing the average pressure P control, sliding velocity V and product PV which does not exceed the allowable value, i.e.:
P ≤ [p] ≤ PV ≤ [v]; V; [pv]
Type: [p], [v] and [pv] as the allowable value
For radial bearings: p=F/ (Bd); v= π d
Type: F- bearing B- bearing d-; width; shaft diameter; the n- shaft speed.
Thrust bearing:
P=F/{(π /4 (d2-d02)) {zeta}; v= PI (d+d0) /2}
Type: D and d0- outer diameter and inner diameter of circular contact surface, usually d0= (0.6 ~ 0.8) d; zeta considered due to open oil channel coefficient decreases the contact area, usually =0.8 ~ 0.9.
