The application of heavy-duty bearings in FAG bearings; it is necessary to consider the operational characteristics of heavy-duty bearings. Heavy-duty bearing operations are often under high stress conditions; and bearings are sensitive to high stresses; It is necessary to reduce the stress of the bearing; and the stress reduction is very beneficial to extend the life of the bearing. For example, the high-load machine under the condition of axial orientation; the single bearing of the original fulcrum is multiplied into two to accept the radial Load; and despite the effects of uneven load; under the same workpiece conditions; the life of the two bearings of the fulcrum is different than the original single bearing; it is expected to progress far more than twice. In fact; in heavy machinery It is often used in a fulcrum to use multiple bearings or multiple rows of bearings to accept radial loads.
Cooperation, clearance and smoothness of heavy-duty bearings in FAG bearings In order to reduce the stress of heavy-duty bearings; it is expected that the smooth film layer is thicker; therefore, it is preferred to use smooth oil with higher viscosity or oil with higher viscosity as base oil. Lipid; together, it is expected to ensure excellent smoothness; because the smoothing agent viscosity does not form too high a conflicting moment.
The cooperative interference of the heavy-duty bearing rotating ferrule is larger than the general condition; and this has a effect on the raceway deformation so that the bearing life has a suffocating effect; thus, under the condition of being able to; the expected interference is appropriately reduced; Appearance roughness; together with smooth and normal; because smooth if it fails; excessively large conflicting moments on the underside of the heavy-duty raceway enhance the trend of cooperative external activities; even the appearance of slipping; although these appearances are more in the outer circle; The circle is also inevitable. The cooperation of the outer circle practice should not present excessive voids; avoid the entry of grease into the appearance; promote the occurrence of slipping appearance; and make the ferrule easy to deform; reduce the bearing area of ​​the bearing.
As long as the useful countermeasures are carefully adopted, it is agreed to appropriately reduce the cooperation and over-profit of heavy-duty bearings; while the interference is slightly reduced; the improvement of the bearing stress condition is greater; of course; the advantage of thickening the oil film is even greater.
Because of the large bearing area under the heavy load, the contact area is large; the cooperation is tight; the ferrule is close to the amount and the deformation is large; therefore, the clearance of the general bearing is also larger.
