Description
Technical Field
The utility model relates to a bearing technical field specifically is novel tapered roller bearing flange structure.
Background
The tapered roller bearing belongs to a separated bearing, and the inner ring and the outer ring of the bearing are both provided with tapered roller paths. The bearing is divided into single-row, double-row and four-row tapered roller bearings according to the number of rows of rollers. The single-row tapered roller bearing can bear radial load and single-direction axial load. When the bearing bears radial load, an axial component force is generated, so when another bearing capable of bearing axial force in the opposite direction is needed for balancing, the flange structure is generally used for placing the roller in a manner of being matched with the outer ring, and the contact section of the general flange structure and the roller is an inclined flange, so that the contact stress distribution is easy to generate unevenness, the bearing is easy to generate a heating phenomenon in the use process, and the service life is reduced.
SUMMERY OF THE UTILITY MODEL
To prior art's not enough, disclosed novel tapered roller bearing flange structure, including outer lane, flange structure and tapered roller, tapered roller joint is between outer lane and flange structure, and the tapered roller both ends are first terminal surface and second terminal surface respectively, and first terminal surface cross section is less than the second terminal surface cross section, and flange structure middle part still is equipped with the mounting groove, and the mounting groove is close to second terminal surface one side and is equipped with second correction line flange.
Preferably, one side of the mounting groove, which is close to the first end face, is also provided with a first correction line flange.
Preferably, the first correction line rib is convex toward the tapered roller.
Preferably, the second correction line rib is convex toward the tapered roller.
Preferably, an oil filling groove is formed in the contact position of the second correction line rib and the mounting groove.
The utility model discloses following beneficial effect has: the correction line flange is provided with the inner side wall surface bulge, so that the contact stress distribution of the flange and the roller can be improved, the lubrication is improved, the friction heating is reduced, and the like.

Referring to fig. 1-3, the novel tapered roller bearing flange structure includes an outer ring 1, a flange structure 2 and a tapered roller 3, the tapered roller 3 is clamped between the outer ring 1 and the flange structure 2, two ends of the tapered roller 3 are respectively a first end surface 31 and a second end surface 32, a cross section of the first end surface 31 is smaller than a cross section of the second end surface 32, a mounting groove 21 is further disposed in the middle of the flange structure 2, a second correction line flange 5 is disposed on a side of the mounting groove 21 close to the second end surface 32, and the tapered roller 3 is clamped between the outer ring 1 and the flange structure 2, so that an end surface thereof is clamped at the correction line flange.
Specifically, the mounting groove 21 is further provided with a first correction line rib 4 on a side close to the first end surface 31, so that the first end surface 31 and the second end surface 32 are respectively clamped with the first correction line rib 4 and the second correction line rib 5.
Specifically, the first correction line rib 4 is convex toward the tapered roller 3, and the first correction line rib 4 can improve the contact stress distribution between the rib and the tapered roller 3, improve lubrication, reduce friction heat, and the like.
Specifically, the second correction line rib 5 is convex toward the tapered roller 3, and the second correction line rib 5 can improve the contact stress distribution between the rib and the tapered roller 3, improve lubrication, reduce friction heat, and the like.
Specifically, an oil groove 6 is provided at a contact portion of the second correction line rib 5 and the mounting groove 21, and lubricating oil can be injected into the interior through the oil groove 6 so that the tapered roller 3 rolls.
Example (b): the tapered roller 3 is clamped between the outer ring 1 and the flange structure 2, the end face of the tapered roller is clamped at the position of the correction line flange, the first end face 31 and the second end face 32 are respectively clamped with the first correction line flange 4 and the second correction line flange 5, and the problems of contact stress distribution between the flange and the tapered roller 3, lubrication, friction heating reduction and the like can be improved by the correction line flange.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
