Description
Technical Field
The utility model relates to a rolling mill bearing frame anti-drop snap ring belongs to metallurgical industry rolling mill equipment maintenance technical field.
Background
In the assembly of the bearing seat and the roller of the rolling mill of the cold rolling continuous rolling mill set in the metallurgical enterprise, the clamping ring is arranged in the roller clamping groove and used for axially positioning the bearing seat and the roller. Because the rolling mill vibrates violently in the process of rolling the plate strip, the clamping ring for positioning the bearing seat and the roller is fixed by only one bolt, the vibration easily enables the fixing bolt of the clamping ring to be loosened, when the bolt is loosened to a certain degree, the bolt falls off, the clamping ring is opened, and then the clamping ring falls off. The snap ring falls off to cause the axial movement of the roller and the bearing seat, so that the bearing seat falls off to cause the strip breakage accident of the rolling mill.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a rolling mill bearing frame anti-drop snap ring can guarantee the axial positioning of rolling mill bearing frame and roll, avoids the snap ring to drop the rolling mill that causes and takes the accident absolutely, solves the problem that exists among the background art.
The technical scheme of the utility model is that:
the utility model provides a rolling mill bearing frame anti-drop snap ring, contains snap ring base member, driving shaft, spring, connecting rod, driven shaft, bolt, initiative shaft hole and driven shaft hole, two semicircle rings of snap ring base member for having certain thickness, the one end of two semicircle rings is passed through the round pin hub rotation and is connected, and the other end of two semicircle rings has the radial bolt that is equipped with of a semicircle ring at least, and the axial of two semicircle ring other ends is equipped with initiative shaft hole and driven shaft hole respectively, and driving shaft and driven shaft set up respectively in initiative shaft hole and driven shaft hole, and the spring housing is on the driving shaft, and driving shaft and driven shaft.
The driven shaft and the driven shaft hole are cylindrical and matched with each other, and the driving shaft hole are stepped cylindrical and matched with each other.
The driven shaft hole on the semicircular ring is a blind hole, and the driving shaft hole is a through hole.
And holes matched with the driving shaft and the driven shaft are respectively arranged at two ends of the connecting rod.
Adopt the utility model discloses, the draw-in groove position of roll is arranged in with this snap ring after bearing frame and the roll assembly to fasten it with the bolt, when the bolt is not hard up to drop, can effectively prevent the roof beam volume semicircle ring to open through connecting rod, driven shaft, driving shaft and the epaxial spring of driving, thereby avoid the snap ring to drop.
The utility model has the advantages that: the axial positioning of the rolling mill bearing seat and the roller can be ensured, and the strip breakage accident of the rolling mill caused by the falling of the snap ring is avoided.
