Abstract
The invention relates to a four-line column roller bearing with strong oil fog lubricating device, which is used for steel plant rolling machine. The four-line column roller bearing includes an outer retainer ring, an inner ring, an outer ring, a middle retainer ring, rollers and a holding frame, wherein a lubricating oil pore is equipped on outer diameter oil groove of the bearing outer ring, a lubricating oil nozzle is arranged in the oil pore, joint of the lubricating oil nozzle and the oil pore is sealed by oil nozzle O-shaped sealing ring to form a first seal, two grooves are equipped at two sides of the outer ring outer diameter oil groove, and a outer ring outer diameter O-shaped sealing ring is inlaid in the two grooves to form a second seal. The bearing can be lubricated equably by oil fog formed by lubricating oil nozzle mounted on the bearing, thereby saving lubricating oil and sufficiently lubricating the bearing.
Description
Technical field
The utility model belongs to technical field of bearings, relates to a kind of four-line column roller bearing with powerful oil mist lubrication device, is steel mill's milling train bearing.
Background technique
Originally milling train is that lubricant oil passes through the oilhole injection bearing with the lubricating system of bearing, and bearing is lubricated.This lubricating system is lubricated insufficient to bearing, and the lubricant oil waste is serious.
Summary of the invention
The purpose of this utility model just provides a kind of four-line column roller bearing with powerful oil mist lubrication device, to reach fully lubricated, saves lubricant oil.
Technical solution of the present utility model is that a kind of four-line column roller bearing with powerful oil mist lubrication device is made up of outer back-up ring 1, inner ring 2, outer ring 5, guide ring 6, roller 7 and retainer 8.Bearing outer ring 5 external diameter oil grooves are provided with oilhole, grease fitting 3 is housed in the oilhole, grease fitting 3 is sealed by oil nozzle O RunddichtringO 4 with the oilhole cooperation place, form the sealing of first road, 5 external diameter oil groove both sides, outer ring have two grooves, stud with outer ring external diameter O RunddichtringO 9 in the groove, form the sealing of second road.Oilhole is 12.
The beneficial effect that the utility model reached is: strong lubricating device of the present utility model is by external high pressure injection system, insert extreme pressure lubricant, form mist of oil, uniformly bearing is lubricated by the grease fitting that is contained on the bearing, both saved lubricant oil, again can the sufficient lubrication bearing.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the local structure for amplifying schematic representation of grease fitting of the present utility model and oil nozzle O RunddichtringO.
Among the figure: 1, outer back-up ring, 2, inner ring, 3, grease fitting, 4, oil nozzle O RunddichtringO, 5, the outer ring, 6, guide ring, 7, roller, 8, retainer, 9, outer ring external diameter O RunddichtringO.
Embodiment
As shown in Figure 1, the utility model strong lubricating device inserts extreme pressure lubricant by external high pressure injection system, forms mist of oil by the grease fitting that is contained on the bearing, uniformly bearing is lubricated, and has both saved lubricant oil, again can the sufficient lubrication bearing.Bearing outer ring 5 external diameter oil grooves have 12 oilholes, and copper oil mist lubrication oil nozzle is housed in the oilhole, and the sealing of first road is formed by 3 sealings of oil nozzle O RunddichtringO in oil nozzle and oilhole cooperation place, prevents oil leakage.High pressure oil forms mist of oil by oil nozzle bearing is lubricated.5 external diameter oil groove both sides have two grooves in the outer ring, and edge forms the sealing of second road by 9 sealings of outer ring external diameter O RunddichtringO in the groove, prevents oil leakage, guarantees the lubricating oil pressure that injects.
