Description
Technical Field
The utility model relates to a roller bearing field, concretely relates to improve lubricated effect's of bearing big flange structure.
Background
A roller bearing is a bearing that rotates in circumferential contact with a plurality of rollers typically mounted on a cage. The roller bearing can achieve good precision and rigidity through pre-tightening. And the tapered inner ring can be used to adjust the working play of the bearing at will. The solution can completely meet the requirement of zero clearance of the roller bearing of the printer.
A tapered roller bearing is one of roller bearings, a large flange surface of an inner ring of the tapered roller bearing and a ball base surface of a rolling body are a kinematic pair, when the bearing rotates, a roller rotates on an inner raceway surface, the ball base surface (spherical surface) of the roller and the large flange surface slide, the posture is unstable, and the tapered roller bearing is a weak link of the tapered roller bearing. According to the statistics of bearing failure, the wear and damage of the large flange surface of the bearing accounts for a high failure proportion.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a to the big flange face wearing and tearing of current tapered roller bearing, the damaged big problem that the proportion that accounts for utensil became invalid have designed a big flange structure that improves the lubricated effect of bearing and has replaced original big flange face promotion tapered roller bearing's lubricated effect, reduce big flange face wearing and tearing and then extension bearing life.
A big flange structure for improving bearing lubrication effect comprises: the inner ring comprises an inner ring top surface, a top surface guide surface, a chamfer angle arc surface, a flange guide surface and a large flange surface;
the top surface of the inner ring is positioned on the top surface of the bearing inner ring, and the whole top surface of the inner ring is arranged in an annular plane;
the top surface guide surface is formed by extending the inner edge of the top surface of the inner ring to the inner side in an inclined way;
the chamfer arc surface is formed by extending the inner edge of the top surface guide surface;
the included angle between the flange guide surface and the vertical surface is 8-12 degrees;
the flange guide surface is formed by extending the inner edge of the chamfer arc surface to the inner side in an inclined way;
the large flange surface is formed by extending the inner edge of the flange guide surface to the inner side in an inclined way.
Preferably, the length ratio of the top guide surface to the rib guide surface is 0.5 to 0.6.
Preferably, the top surface guide surface and the top surface of the inner ring form an included angle of 15 degrees.
Preferably, the flange guide surface forms a tapered surface with an angle of 10 degrees with the vertical surface.
Preferably, the length of the flange guide surface is 0.119 mm.
The radius of the chamfer angle arc surface is 0.6 mm.
The prior structure can cause the bearing to fail early due to insufficient lubrication in the using process, and the lubrication condition of the bearing cannot be improved by improving the lubrication mode due to the limitation of the structure and the size of the mounting part. To this end, a flange guide surface is added for introducing (flowing) the lubricating oil into the large flange surface so that the lubricating oil can form an oil film between the large flange surface and the ball base surface of the roller.
The beneficial effects of the utility model reside in that: the structure is simple and convenient to process, the lubricating and maintaining effect is effectively increased, the friction is reduced, and the service life is prolonged.

Detailed Description
The technical solution of the present invention is further specifically described below by way of specific embodiments and with reference to the accompanying drawings.
Example 1
As shown in fig. 1, 2 and 3, the large flange structure for improving the lubrication effect of the bearing comprises: the inner ring comprises an inner ring top surface, a top surface guide surface, a chamfer angle circular arc surface, a flange guide surface 1 and a large flange surface 2;
the top surface of the inner ring is positioned on the top surface of the bearing inner ring, and the whole top surface of the inner ring is arranged in an annular plane;
the top surface guide surface is formed by extending the inner edge of the top surface of the inner ring to the inner side in an inclined way;
the chamfer arc surface is formed by extending the inner edge of the top surface guide surface;
the flange guide surface 1 is formed by extending the inner edge of a chamfer arc surface to the inner side in an inclined way;
the large flange surface is formed by extending the inner edge of the flange guide surface 1 to the inner side in an inclined way.
The included angle between the top surface guide surface and the top surface of the inner ring is 15 degrees.
The included angle between the flange guide surface 1 and the vertical surface is 10 degrees, and a conical surface is formed.
The length of the flange guide surface 1 is 0.119 mm.
The radius of the chamfer angle arc surface is 0.6 mm.
The prior structure can cause the bearing to fail early due to insufficient lubrication in the using process, and the lubrication condition of the bearing cannot be improved by improving the lubrication mode due to the limitation of the structure and the size of the mounting part. To this end, a flange guide surface 1 is added for introducing (flowing) the lubricating oil into the large flange surface so that the lubricating oil can form an oil film between the large flange surface and the ball base surface of the roller.
