Selection of rolling bearing oil

07-26

Selection of rolling bearing oil

Spindle bearing lubricants using rolling bearings are generally considered based on the product of the bearing inner diameter d and the spindle speed n, that is, the speed factor dn, the bearing operating temperature T, and the load P borne by the bearing. The variety of lubricating oil can choose COC high temperature resistant grease bearing oil, which can be determined according to product variety, working conditions and viscosity grade.   Bearing working temperature -30-0℃, normal load (3MPa) suitable oil viscosity (40℃) 18-32mm2/s, viscosity grade 22, 32; heavy load or shock load (3MPa-20MPa) suitable oil viscosity (40℃) ) 18-50mm2/s, viscosity grade 32, 46.   Bearing operating temperature 0-60℃, speed factor (dn value) below 15000mm.r/min, normal load suitable oil viscosity (40℃) 32-70mm2/s, viscosity grade 32, 46, 68, heavy load or impact load (3MPa-20MPa) Applicable oil viscosity (40℃) 70-192mm2/s, viscosity grade 68, 100, 150;   Speed ​​factor (dn value) 15000-75000mm.r/min, normal load suitable oil viscosity (40℃) 32-50mm2/s, viscosity grade 32, 46, heavy load or impact load (3MPa-20MPa) suitable oil viscosity ( 40℃) 42-90mm2/s, viscosity grade 46, 68, 100;   Speed ​​factor (dn value) 75000-150000mm.r/min, normal load suitable oil viscosity (40℃) 15-32mm2/s, viscosity grade 15, 32, heavy load or impact load (3MPa-20MPa) suitable oil viscosity ( 40℃)32-42mm2/s, viscosity grade 32; speed factor (dn value) 150000-300000mm.r/min, normal load suitable oil viscosity (40℃) 9-12mm2/s, viscosity grade 5, 7, 10, Heavy load or shock load (3MPa-20MPa) is suitable for oil viscosity (40℃) 18-32mm2/s, viscosity grade 15.   Bearing working temperature 60-100℃, speed factor (dn value) below 15000mm.r/min, normal load suitable oil viscosity 40℃110-192mm2/s (100℃9.3-12.5mm2/s), viscosity grade 150, heavy load Or impact load (3MPa-20MPa), suitable for oil viscosity (40°C) 195-240mm2/s (100°C 15-24mm2/s), viscosity grade 150;   Speed ​​factor (dn value) 15000-75000mm.r/min, normal load is suitable for oil viscosity 40℃70-120mm2/s (100℃5.6-9.3mm2/s), viscosity grade 68, 100, heavy load or impact load ( 3MPa-20MPa) suitable oil viscosity (40℃) 110-192mm2/s, viscosity grade 150; speed factor (dn value) 75000-150000mm.r/min, normal load suitable oil viscosity 40℃50-90mm2/s(100℃ 5.6-9.3mm2/s), viscosity grade 46, 68, 100, heavy load or shock load (3MPa-20MPa) suitable for oil viscosity (40℃) 70-120mm2/s, viscosity grade 100.

Adjustment of bearing axial clearance

07-26

Adjustment of bearing axial clearance

The axial clearance inside the bearing can be achieved by moving the axial position of the outer ring.   1 Adjusting shim method   Fill a set of soft material (soft steel or elastic paper) gaskets between the bearing end cover and the end surface of the bearing seat; when adjusting, first install the bearing end cover without placing the gasket, and tighten the bearing end cover evenly on the same side. Screw, while turning the shaft by hand, until the bearing rolling element is in contact with the outer ring and there is no gap inside the shaft; at this time, measure the gap between the bearing end cover and the end surface of the bearing seat, plus the shaft required by the bearing in normal operation Toward the gap; this is the total thickness of the gasket to be filled, and then fill the prepared gasket between the bearing end cover and the end face of the bearing seat, and finally tighten the screws.   2 Adjusting bolt method   Press the pressure ring on the outer ring of the bearing and use the adjustment bolt to pressurize; before the pressure adjustment, first measure the pitch of the adjustment bolt, and then slowly tighten the adjustment bolt until there is no gap in the bearing, and then calculate the adjustment The corresponding rotation angle of the bolt. For example, if the pitch is 1.5mm, the clearance required for the normal operation of the bearing, then the required rotation angle of the adjustment bolt is 3600×0.1535=360; at this time, if the adjustment bolt is reversed 360, the bearing will obtain an axial clearance of 0.5mm , And then fix it with a stop washer.
