Description
Technical Field
The utility model relates to a hollow axle locking device of speed reducer for heating furnace water-cooling stove roller belongs to metallurgical industry steel rolling equipment technical field.
Background
The water-cooled furnace roller is a roller commonly used in a heating furnace in the metallurgical industry, is mainly used for conveying strip steel on a cold-rolled strip steel production line, and is generally driven by a suspension type speed reducing motor, such as a hearth roller of a hot galvanizing heating furnace. After the furnace roller is used for a period of time, the gap between the furnace roller shaft and the inner hole of the hollow shaft of the speed reducer is enlarged, so that the speed reducer motor idles, the furnace roller is not moved, the furnace roller does not rotate, the lower surface of the plate belt is scratched, and quality accidents occur.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a speed reducer hollow shaft locking device for heating furnace water-cooling stove roller can avoid the idle running of speed reducer to avoid taking place quality accidents such as slab band fish tail, solve the problem that exists among the background art.
The technical scheme of the utility model is that:
the utility model provides a speed reducer hollow shaft locking device for heating furnace water-cooling stove roller, contain the bearing frame, stove roller shaft, locking flange, locking screw, lock nut, speed reducer hollow shaft and rotary joint, the one end of stove roller shaft is passed through the bearing and is installed on the bearing frame, the other end of stove roller shaft is equipped with rotary joint, stove roller shaft suit is in the speed reducer hollow shaft, locking flange and stove roller shaft fixed connection are passed through to the one end of speed reducer hollow shaft, lock nut threaded connection is at the other end of speed reducer hollow shaft, lock nut's radial is equipped with a plurality of lock screw.
The speed reducer hollow shaft and the furnace roller shaft are concentrically arranged.
And one end of the hollow shaft of the speed reducer is provided with an external thread matched with the locking nut.
And screw holes matched with the locking screws are respectively arranged on the hollow shaft of the speed reducer and the locking nuts.
The central lines of the screw holes on the hollow shaft of the speed reducer and the locking nut are perpendicular to the central lines of the hollow shaft of the speed reducer and the locking nut.
The utility model has the advantages that: the two ends of the hollow shaft of the speed reducer are respectively locked with the furnace roller shaft through the locking flange, the locking nut and the locking screw, so that the normal operation of the furnace roller can be effectively guaranteed, the idle running of the hollow shaft of the speed reducer is avoided, and quality accidents such as plate belt scratch are avoided.
