Abstract
The invention discloses a drum-shaped tooth type shaft coupling comprising a shaft, an external tooth shaft sleeve, an internal tooth ring, a connecting disk and a connecting ring sleeve, wherein the connecting disk is connected on the end face of an output shaft of a speed reducer to be assembled by a locking bolt; the internal tooth ring is sleeved on the output shaft of the speed reducer to be assembled by a spline and is pressed on the connecting disk; the external tooth shaft sleeve is sleeved on the shaft by the spline and is in interference fit with the shaft, and the external tooth shaft sleeve is hung on the internal tooth ring and is engaged with the internal tooth ring; the connecting ring sleeve is fixedly connected with the output shaft of the speed reducer to be assembled, and the external circle of the connecting ring sleeve is matched with the internal circle of the connecting disk by screw threads; since the drum-shaped tooth type shaft coupling of the invention adds the connecting ring sleeve between the connecting disk and the output shaft of the speed reducer, the impact force of blanks and the vibratory force of an upper roller and a lower roller are almost centralized on the connecting ring sleeve when the rollers roll the blanks, thereby greatly lighten the pulling force and the shearing force borne by the locking bolt, avoiding the locking bolt from being pulled apart or sheared off, lowering the equipment failure of a vertical type rolling mill, and further enhancing the production efficiency.
Description
Technical field
The present invention relates to a kind of vertical mill that is applicable to rolling various steel, relate in particular to the drum-shaped tooth type shaft coupling parts that use on a kind of vertical mill.
Background technique
Vertical mill mainly becomes various required section bars to the billet rolling of smelting moulding by casting.Retarder, drum-shaped tooth type shaft coupling and roll that vertical mill is mainly driven by power motor, power motor, wherein drum-shaped tooth type shaft coupling is a critical component, plays a part to give roll the transmission of power of reducer output shaft.Therefore, whether the quality of drum-shaped tooth type shaft coupling directly affects vertical mill and can normally move, thereby affects whole steel rolling production-line.
In the prior art, drum-shaped tooth type shaft coupling comprises axle, external tooth axle sleeve, ring gear and land, land is connected on the end face of reducer output shaft to be assembled by lock bolt, ring gear by spline package on the output shaft of retarder to be assembled and be pressed on the land, the external tooth axle sleeve by spline package on axle and with the axle interference fit, the external tooth axle sleeve is suspended on the ring gear and with the ring gear tooth by pressing plate and lock bolt and meshes.The drum-shaped tooth type shaft coupling of said structure in use, whole axle is pressed on the land of fixedlying connected with the end face of reducer output shaft by external tooth axle sleeve and ring gear, almost the gravity of whole drum-shaped tooth type shaft coupling is all concentrated and is pressed on the land.Roll is when rolling blank; be subjected to the impact of blank and the vibration of top and bottom rolls; the lock bolt that connects land and retarder not only is subjected to pulling force but also be subjected to shearing force; lock bolt is very easily broken or is sheared disconnected under the long-term high speed rotating of drum-shaped tooth type shaft coupling, and land is in the ring gear, can not be found at any time; after treating that whole lock bolts lost efficacy; whole drum-shaped tooth type shaft coupling breaks away from from the output shaft of retarder, causes equipment downtime, has seriously influenced back road manufacturing procedure.
Summary of the invention
At above-mentioned deficiency, the invention provides a kind of drum-shaped tooth type shaft coupling, strengthen the Placement of land and reducer output shaft, alleviate suffered pulling force of lock bolt or shearing force, avoid drum-shaped tooth type shaft coupling when high speed rotating, to be broken or shear disconnected, reduce the equipment failure of vertical mill, further enhance productivity.
Drum-shaped tooth type shaft coupling provided by the invention comprises axle, external tooth axle sleeve, ring gear, land and is connected ring set that land is connected on the end face of reducer output shaft to be assembled by lock bolt; Ring gear by spline package on the output shaft of retarder to be assembled and be pressed on the land; The external tooth axle sleeve by spline package on axle and with the axle interference fit, the external tooth axle sleeve is suspended on the ring gear and with ring gear and meshes; Connect ring set and fixedly connected, the interior flexible screw-thread fit of crossing of its cylindrical and land with the output shaft of retarder to be assembled.
Further, the interior round Spielpassung of the cylindrical of described land and ring gear.
Beneficial effect of the present invention: drum-shaped tooth type shaft coupling of the present invention connects ring set and is fixedly installed on the output shaft of retarder by being connected ring set setting up between land and the reducer output shaft, and its cylindrical cooperates with interior the justifying of land by screw thread.Roll is when rolling blank, the impact force of blank and the vibration force of top and bottom rolls have nearly all focused on connecting ring and have put, and have alleviated suffered pulling force and the shearing force of lock bolt greatly, avoid lock bolt to be broken or shear disconnected, reduce the equipment failure of vertical mill, further enhance productivity.
Description of drawings
Accompanying drawing is a cross section view of the present invention.
Embodiment
Accompanying drawing is a cross section view of the present invention, and as shown in the figure: drum-shaped tooth type shaft coupling comprises axle 1, external tooth axle sleeve 2, ring gear 3, land 4 and is connected ring set 7.Connect ring set 7 and be welded on the end face of reducer output shaft 8, its cylindrical is provided with outside thread, and the interior circle of land 4 is provided with internal thread, and land 4 is connecting ring set 7 by the screw-thread fit rotation set, and is fixedly connected on the reducer output shaft 8 by lock bolt 5.Ring gear 3 by spline package on the output shaft of retarder to be assembled and be pressed on the upper-end surface of land 4.External tooth axle sleeve 2 by spline package on axle 1 and with axle 1 interference fit, external tooth axle sleeve 2 is suspended on the ring gear 3 and with ring gear 3 teeth by pressing plate 6 and lock bolt 9 and meshes.Roll is when rolling blank, the impact force of blank and the vibration force of top and bottom rolls are by being connected ring set 7 and land 4 is born jointly, bigger because of connecting the stressed cross section of ring set 7, pulling force and shearing force nearly all concentrate on connecting ring and put, suffered pulling force and the shearing force of lock bolt 5 is less, thereby avoid lock bolt to be broken or shear disconnected, reduced the equipment failure of vertical mill.
In the present embodiment, the interior circle of the cylindrical of land 4 and ring gear 3 is a Spielpassung.Roll is when rolling blank, the impact force of blank and the vibration force of top and bottom rolls make axle 1 have slight swing, slight swing makes the outer surface of land 4 and the internal surface of ring gear 3 have certain collision, the shearing force that the aggravation lock bolt is suffered with being connected ring set 7, after adopting Spielpassung, there is certain clearance in the interior circle of the cylindrical of land 4 and ring gear 3, can avoid the outer surface of land 4 and the internal surface of ring gear 3 to produce collision effectively.
Explanation is at last, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technological scheme of the present invention, and not breaking away from the aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
