Abstract
The utility model discloses a double-channel rolling bearing, belonging to the field of bearings. The conventional bearing has the defects that lubricating oil is not uniformly dispersed so that the service life is shortened. The double-channel rolling bearing comprises an outer ring, core shafts, rolling bodies, a retainer, an oiling ring, dustproof rings and an oil dispersing ring, wherein the oil distributing ring can reasonably disperse the lubricating oil to each part. The rolling bodies are arranged between the outer ring and channels arranged at the core shafts, and the rolling bodies are uniformly separated through the retainer. Two sides of the outer ring are provided with steps, and the dustproof rings are sheathed on the core shafts and are propped against the steps. An annular groove is arranged at the middle part of the outer body side of the outer ring, and an oiling hole is arranged in the groove position. The oiling ring is inlaid at the annular groove in the outer ring and covers the oiling hole. An oil dispersing slot is formed in the middle part of the inner body side of the outer ring, and the oiling hole is communicated with the oil dispersing slot and the annular groove of the outer body side of the outer ring. A through hole is axially arranged in the oil dispersing ring, and the through hole is larger than the radial diameter of the core shaft. A positioning card slot is arranged on the inner side of the outer ring, and the oil dispersing ring is inserted into the inner side of the outer ring. An annular bump of the rear end of the oil dispersing ring is correspondingly buckled into the positioning card slot. The lubricating oil can be uniformly dispersed through the double-channel rolling bearing, the overhigh local temperature is avoided, the working precision is increased, and the service life of the bearing is prolonged.
Description
Technical field
The utility model belongs to field of bearings, and especially to spin the double channel rolling bearing that the high speed revolving cup uses relevant with a kind of revolving cup.
Background technique
At present, the bearing that is used on the high speed revolving cup comprises outer ring, mandrel, retainer, rolling element, oiling ring and dust ring.Employing places rolling element between the raceway groove that outer ring and mandrel be provided with; Evenly separate rolling element with retainer; Rolling element will remain rolling element relative distance motion of being separated by; Dust ring puts mandrel and places in the dustproof groove of outer ring, and the outer ring is provided with tank filler sleeve, covers this tank filler sleeve with oiling ring.Add lubricant oil through tank filler sleeve, because the lubricant oil in this structure can not be distributed to each position well, it is inhomogeneous that two raceway grooves are refueled; The raceway groove lubrication effect is inconsistent; The bad channel temperature of lubrication effect is understood the too early rated temperature that surpasses, and not only can make the precision step-down, and it is big that noise becomes; And wear out failure is accelerated, also reduce greatly working life.
The model utility content
The purpose of the utility model is exactly to exist the inhomogeneous defective that causes the life-span reduction of lubricant oil dispersion in order to overcome existing bearing, and a kind of double channel rolling bearing that can make lubricant oil ability reasonable distribution to each position is provided.For this reason, the utility model adopts following technological scheme:
A kind of double channel rolling bearing comprises outer ring, mandrel, rolling element, retainer, oiling ring and dust ring, and rolling element places between the raceway groove that outer ring and mandrel be provided with; Evenly separate rolling element with retainer, retainer will remain rolling element relative distance motion of being separated by, and the both sides, outer ring are provided with step; Dust ring puts mandrel and abuts on this step, and the ectosome middle side part of outer ring is provided with annular groove, offers tank filler sleeve on this annular groove position; Oiling ring is flush-mounted in the annular groove on the outer ring and covers this tank filler sleeve, when needing lubricating oil filling, opens oiling ring and passes through tank filler sleeve to the inner lubricating oil filling of bearing; It is characterized in that: described a kind of double channel rolling bearing also comprises the oil distributing ring that can lubricant oil rationally be distributed to each position, and this oil distributing ring axially is provided with a through hole, and this through hole is bigger than the radial diameter of mandrel; The inboard, outer ring is provided with locating groove; Oil distributing ring is plugged in the inboard, outer ring, and the annular projection correspondence of oil distributing ring rear end snaps in the locating groove, and is spacing to oil distributing ring.
The middle part on side offers the branch oil groove in the said outer ring, described tank filler sleeve with this minute oil groove and said outer ring outside annular groove on the side be communicated with, divide oil groove can the lubricant oil that from tank filler sleeve, adds be distributed on the circumference uniformly.
Use the utility model can reach following beneficial effect: to avoid the lubricated imbalance that causes owing to lubricating oil filling is inhomogeneous, made the bearing local temperature too high; Temporarily storage lubricant oil is constantly supplied with bearing during work, makes the maintenance lubrication effect that raceway groove can be more permanent, thereby has prolonged the working life of bearing; Lubricant oil is evenly distributed and can reduces noise effectively, improves the working environment of workers; The balanced bearing inside temperature of ability improves operating accuracy in the working procedure.
Description of drawings
Fig. 1 is the sectional drawing of the utility model master apparent direction.
