The utility model relates to technical field of bearings, relates generally to a kind of structural type of enhanced type entity tapered roller bearing.
Background technique
At present, tapered roller bearing, as shown in Figure 1: Qi You outer ring 11, inner ring 12, roller 13, retainer 14 form; Raceway and the roller of Internal and external cycle are taper, the line stretcher of all conical surfaces merge on bearing axis certain a bit, retainer adopts stamping steel plate structure, have lightweight, can bear the advantages such as bidirectional load.But the shortcoming such as owing to being subject to the impact of structural design, machining accuracy and bearing assemble technique, this product ubiquity bearing capacity is low, the life-span is short, noise is large during high speed, greasy property is poor.
Model utility content
The purpose of this utility model is to provide a kind of solid cage and uses the enhanced type entity tapered roller bearing of this retainer, and this bearing has the advantages such as bearing capacity is high, long service life, smooth running, low friction, greasy property is good, resistance to shock is good.
The purpose of this utility model can adopt following technological scheme to realize: a kind of solid cage, it is characterized in that, at described solid cage, circumferentially by numerical control milling machine, mill out some roller mounting holes, roller mounting hole is shaped as the radially straight hole identical with roller wrapping angle angle, and roller mounting hole outside packs portion into for roller; Solid cage entity portion is the some lintels between two side rings and ring and ring, the side of described lintel is symmetrical respectively arranges two lock points, each lock point is the square draw-in groove being formed by two square protrusion, and described square draw-in groove inwardly mills out an arc shaped surface coordinating with roller.
Further, the Si Ge corner of described roller mounting hole is provided with circular arc chamfering.
A kind of enhanced type entity tapered roller bearing, comprise inner ring, outer ring, tapered roller and solid cage, it is characterized in that, at described solid cage, circumferentially by numerical control milling machine, mill out some roller mounting holes, roller mounting hole is shaped as the radially straight hole identical with roller wrapping angle angle, and roller mounting hole outside packs portion into for roller; Solid cage entity portion is the some lintels between two side rings and ring and ring, the side of described lintel is symmetrical respectively arranges two lock points, each lock point is the square draw-in groove being formed by two square protrusion, and described square draw-in groove inwardly mills out an arc shaped surface coordinating with roller; Tapered roller relies on the lock point on solid cage to guide retainer rotation;
Described inner ring outer surface is provided with the U-shaped draw-in groove coordinating with tapered roller, and tapered roller packs roller mounting hole into by solid cage outside, and is combined into inner ring assembly with inner ring.
Further, described tapered roller both sides end face all adopts protruding Spherical Surface S R design, in described U-shaped draw-in groove and square draw-in groove, designs for concave spherical surface with the end face of tapered roller cooperation place.
Further, the Si Ge corner of described roller mounting hole is provided with circular arc chamfering.
By structure above, can be found out, the retainer of the utility model design adopts machining one-body molded, and roller mounting hole is shaped as the radially straight hole identical with roller wrapping angle angle, has reduced mach technology difficulty on the one hand, has improved the precision of processing; On the other hand, make lubricant grease can more successfully enter bearing inside, the greasy property of bearing is significantly improved.The design optimization of the protruding Spherical Surface S R of roller both sides end face the contact condition of roller and retainer, significantly reduced the contact stress of rib, and formed and can bear the more lubricant film of high loading, under bearing normal operation, the wearing and tearing and the fatigue that between retainer or inner ring and roller end face, due to contact slide, cause have been avoided.Solid cage is compared with the board-like retainer of stamped steel, and retainer intensity has obtained large increase, can suitably increase roller diameter or quantity, thereby improves the load bearing capacity of bearing.Roller mounting hole is that segment straight line contacts with the rolling surface of roller, coordinates reasonably Suo Dian position to distribute, the running that makes bearing more steadily, more flexible.In sum, the utlity model has the advantages such as bearing capacity is high, long service life, smooth running, low friction, greasy property is good, resistance to shock is good.
