Abstract
The utility model provides a continuous casting billet output roll shaft coupling adopts the convex-concave meshing to be connected between the half gear shaft coupling of output roll axle head and the half gear shaft coupling composition face of speed reducer output axle head, and the half gear shaft coupling of output roll axle head corresponds the processing respectively with the terminal surface of the half gear shaft coupling joint of speed reducer output axle head has two at least fan-shaped bosss and recess. Due to the adoption of convex-concave meshing connection, the shearing force born by the fixing bolt can be effectively decomposed, the problem of disconnection of the half-gear coupling caused by shearing of the fixing bolt is avoided, the accident potential is eliminated, the service life of the run-out roller way is prolonged, the consumption of the roller way and the maintenance workload are reduced, the long-time stable operation of the run-out roller way is realized, and the smooth running of continuous casting production is ensured.
Description
Technical field
The utility model belongs to the gearing apparatus field, relates in particular to a kind of coupling of being connected between continuous casting billet output roll shaft and the speed reducer output shaft of being used for.
Background technique
At present; Steel works is used for generally adopting two and half gear couplings to be connected between continuous casting billet output roll shaft and the speed reducer output shaft; Be that the output roller axle head is equipped with half gear coupling; Speed reducer output shaft end also correspondence is equipped with half gear coupling, and the mating face that two and half gear couplings connect is smooth flat, adopts 8 bolts that two and half gear couplings are fixed together; The moment of torsion of speed reducer output shaft output is delivered on the output roll shaft, drives the output roller rotation and carry continuous casting billet.Yet along with the maximization of rolling machinery, the weight of continuous casting billet and volume are also increasing; Therefore the output power of speed reducer also constantly increases, the also corresponding increase of moment of torsion that output shaft transmits, and continuous casting billet continuously seriously clashes into runout table in addition; Make 8 fixing bolts very easily loosening even cut off, thereby cause two and half gear couplings to be thrown off, not only increase maintenance load; Shorten the life-span of runout table, and directly influenced the conveying of continuous casting billet.Especially in a single day cause a plurality of disconnect couplings, just will lead to great manufacturing mechanism accident, its consequence will be more serious.
Summary of the invention
The purpose of the utility model aims to provide a kind of structure and is prone to row, and is safe and reliable, can prevent effectively that fixing bolt from damaging, and guarantees the runout table smooth running, thereby eliminates the continuous casting billet output roller coupling of accident potential.
For this reason, the solution taked of the utility model is:
A kind of continuous casting billet output roller coupling; Half gear coupling of output roller axle head adopts bolt to be connected with half gear coupling of speed reducer output shaft end; It is characterized in that; Adopt convex-concave to be connected with a joggle between the half gear coupling mating face of half gear coupling of output roller axle head and speed reducer output shaft end, corresponding respectively at least two boss and the groove of being processed with of end face of half gear coupling of output roller axle head and half gear coupling of speed reducer output shaft end joint.
Said boss and groove are fan-shaped.
Boss and groove on the half gear coupling end face of half gear coupling of said output roller axle head and speed reducer output shaft end are 4.
The good effect of the utility model is:
Because the utility model is connected with a joggle employing male and female face between the half gear coupling mating face of half gear coupling of output roller axle head and speed reducer output shaft end; Rely on close-fitting boss and groove transmitting torque; Effectively decomposed the shearing force that fixing bolt bore, thereby half gear coupling of having avoided fixing bolt to be cut off and cause breaks off problem, has eliminated accident potential; Prolonged the working life of runout table; Reduce roller-way consumption and maintenance load, realized the long-time smooth running of runout table, guaranteed the direct motion that continuous casting is produced.
Description of drawings
Fig. 1 is a continuous casting billet output roller coupling sectional drawing.
Fig. 2 is the A-A cross-sectional view.
Among the figure: output roller axle sleeve 1, output roll shaft half gear coupling 2, bolt 3, speed reducer output shaft half gear coupling 4, speed reducer output shaft cover 5, boss 6, groove 7.
Embodiment
Visible by accompanying drawing; The utility model continuous casting billet output roller coupling comprises output roll shaft half gear coupling 2 and speed reducer output shaft half gear coupling 4; Output roll shaft half gear coupling 2 is installed on the output roller axle sleeve 1, and speed reducer output shaft half gear coupling 4 is installed on the speed reducer output shaft cover 5.Be fixedly connected through 8 bolts 3 between output roll shaft half gear coupling 2 and speed reducer output shaft half gear coupling 4.The characteristics of the utility model are to have changed output roll shaft half gear coupling 2 into male and female face with speed reducer output shaft half gear coupling 4 mating faces by smooth surface, adopt convex-concave to be connected with a joggle.The end face symmetry that is about to export roll shaft half gear coupling 2 processes 4 fan- shaped boss 6 and 4 scalloped recess 7; Simultaneously with the end face of speed reducer output shaft half gear coupling 4 also symmetry process 4 fan- shaped boss 6 and 4 scalloped recess 7; Shape, the size of both boss 6 and groove 7 are identical, and just the position of 4 fan- shaped boss 6 and 4 scalloped recess 7 is just the opposite.
After the installation, 4 fan-shaped boss 6 of output roll shaft half gear coupling 2 are embedded in 4 shapes of speed reducer output shaft half gear coupling 4, the measure-alike scalloped recess 7 just; Equally, 4 fan-shaped boss 6 of speed reducer output shaft half gear coupling 4 also are installed in 4 scalloped recess 7 of output roll shaft half gear coupling 2 fully, tight 8 fixing bolts 3, can realize that the convex-concave of two and half gear couplings is connected with a joggle.
