The size of the roller bearing is constrained by the space of the rolling mill device (the inner diameter and outer diameter of the bearing depend on the diameter of the roll neck and the roll body); the cross section of the bearing is higher than that of the 粲诒 粲诒 谥岢 欢 欢 腔 匦氤惺 匦氤惺 匦氤惺 匦氤惺 匦氤惺 蟮 蟮The sputum of the sputum is smouldering. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
At present, four-row cylindrical roller bearings and four-row tapered roller bearings are mainly used; double-row cylindrical roller bearings and double-row tapered rollers are also used. Most of the tapered roller bearings use hollow rollers and strut cages; Smooth condition; the outer surface of the bearing and the end face are separated from the oil groove and the oil hole; when it is matched with the roll neck; the inner ring of the inner ring of the bearing is provided with a spiral oil groove.
Roller bearing layout is based on different types of rolling mills; different working conditions and different layout equipment to determine. In general; four-row cylindrical roller bearings simply achieve higher machining accuracy; therefore, with high speed Rotating characteristics; and because of the convenience of disassembly of the device; and the inner ring raceway surface and the roll surface of the roll can be ground after the inner ring is pressed into the roll neck; it is beneficial to improve the rolling precision; and is used for the support of high-speed and high-precision rolling mills. Roller; four-row tapered roller bearing bearing capacity; can accept radial load and axial load together; suitable for low speed and medium speed rolling mill.
