Description

Roller bearing seat snap ring

Technical Field

The utility model relates to a roll chock snap ring belongs to metallurgical industry roll rigging equipment technical field.

Background

The roller is a key device in a steel rolling system, bearing seats are arranged at two ends of the roller to ensure the normal operation of the roller, the clamping ring is a common component for assembling the bearing seats, the diameter of the clamping ring is matched with that of a roller shaft, and the clamping ring is clamped on the roller shaft and rotates in the same direction with an inner ring of the bearing. The bearing seat assembled by the snap ring is found in the using process, the snap ring frequently falls off in the upper machine using process, or the bearing seat falls off due to the failure of the snap ring connection in the roll changing process, so that the normal production is influenced. In addition, after a part of rollers are taken off the machine, the snap ring often breaks down and cannot be normally disassembled in the process of disassembling and assembling the bearing seat, the snap ring must be removed by cutting, spare parts are abnormally scrapped, the bearing seat can be damaged by serious people, and the stable operation of production is greatly influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a roll chock snap ring can avoid the snap ring to drop in the use, guarantees going on steadily of production, solves the problem that exists among the background art.

The technical scheme of the utility model is that:

the utility model provides a roll chock snap ring, contains snap ring A, snap ring B, round pin axle, keyway, connecting bolt, recess and connecting plate, snap ring A and snap ring B be with roll axle assorted semi-circular, and snap ring A and snap ring B's one end is passed through the connecting plate and is in the same place with round pin hub connection, and snap ring A and snap ring B's the other end passes through connecting bolt and links together, is equipped with the keyway on snap ring A and the snap ring B respectively, is equipped with the recess that can expose the connecting bolt head on snap ring B's the surface.

The cross section of the groove on the outer surface of the snap ring B is right-angled.

And the groove on the outer surface of the snap ring B is close to the end part of the snap ring B.

And the end face of the snap ring A is provided with a bolt hole matched with the connecting bolt.

And two ends of the connecting plate are respectively connected with the clamping ring A and the clamping ring B through pin shafts.

Adopt the utility model discloses, the snap ring is when the installation, at first adopts connecting plate and round pin axle riveting with snap ring A and snap ring B's one end, snap ring A and snap ring B can rotate through the round pin axle, install snap ring A and snap ring B on the bearing frame, and make the keyway on snap ring A and the snap ring B match together with the key on the bearing endotheca, ensure snap ring and bearing inner race syntropy and rotate, at last, install snap ring A and snap ring B on the roll axle, and pass through connecting bolt fastening with snap ring A and snap ring B's the other end and be in the same place.

The utility model has the advantages that: simple structure, easy dismounting can avoid the snap ring to drop in the use moreover, guarantees going on steadily of production.

Drawings

FIG. 1 is a schematic structural view of the present invention;

in the figure: snap ring A1, snap ring B2, round pin axle 3, keyway 4, connecting bolt 5, recess 6, connecting plate 7.

Detailed Description

The invention will be further explained by way of example with reference to the accompanying drawings.

Referring to fig. 1, a roll chock snap ring comprises a snap ring a1, a snap ring B2, a pin shaft 3, a key groove 4, a connecting bolt 5, a groove 6 and a connecting plate 7, wherein the snap ring a1 and the snap ring B2 are semicircular and matched with a roll shaft, one ends of the snap ring a1 and the snap ring B2 are connected together through the connecting plate 7 and the pin shaft 3, the other ends of the snap ring a1 and the snap ring B2 are connected together through the connecting bolt 5, the key grooves 4 are respectively arranged on the snap ring a1 and the snap ring B2, and the groove 6 capable of exposing the head of the connecting bolt 5 is arranged on the outer surface of the snap ring B829.

The specific embodiment is as follows:

in this embodiment, referring to fig. 1, the number and size of the key slots 4 on the snap ring a1 and the snap ring B2 are matched with the keys used for assembling the inner race of the bearing, so as to ensure that the snap ring rotates in the same direction as the inner race of the bearing during the assembly process, and prevent the snap ring from falling off during the use process.

Groove 6 on the snap ring B2 surface is close to the one end of snap ring B2, and the cross-section of groove 6 is right angle shape, and the one side of groove 6 is parallel with the tip plane of snap ring B2, and the size matches with connecting bolt 5 head, and the another side is perpendicular with the tip plane of snap ring B2, and connecting bolt 5 head exposes, makes things convenient for connecting bolt 5's dismantlement can be ensured to the size of groove 6.
