The keyway of structure is interference fit, and the keyway of the central hole of the worm gear in flat key and worm gear case is clearance fit, roll adjustment leading screw
Right end be equipped with and bulb and be hinged by bulb and bearing block, two groups of balances are held out against on center line of the component on roll adjustment leading screw
Under be symmetrical arranged.
Balance positioned at upside, which holds out against component, includes screw rod, pressure cap, spring, nut and sliding sleeve, and sliding sleeve is fixed on slideway
Left side, screw rod are threaded through in sliding sleeve along left and right horizontal direction, and the right end of screw rod is hinged on bearing block, and pressure cap and spring are arranged
On screw rod, between pressure cap and sliding sleeve, nut thread is connected on screw rod and positioned at the left side of pressure cap spring.
Spring is compression spring or disk spring.
Using above-mentioned technical proposal, the utility model is specifically assemblied in the rack of calender, and the roller of calender
Both ends are each equipped with one group, when carrying out roller gap adjustment, while start two groups of decelerating motors at rolling mill roller both ends, subtract
Speed motor drives the worm screw in worm gear case to rotate, and worm screw drives worm gear to rotate, since the left end of roll adjustment leading screw passes through flat key and snail
Wheel connection, and roll adjustment leading screw is threadedly coupled with the screw being fixed on slideway, so roll adjustment leading screw is moved along its axial direction,
So as to which roll adjustment leading screw pulls bearing block to be moved along slideway, rolling mill roller movement, so that the gap between completing rolling mill roller
Adjustment, in addition two groups of balances hold out against component and enable to the internal thread in external screw thread and screw on roll adjustment leading screw closely to connect all the time
Touch, so that rolling mill roller will not move, the specific mechanism of action is：As shown in Figure 1, under the action of the spring, screw rod by
All the time to the left, therefore screw rod pulls bearing block to the left, therefore roll adjustment leading screw stress is to the left for power, cause the external screw thread of roll adjustment leading screw with
Screw internal thread fits closely.
In conclusion the utility model can be adjusted the gap between rolling mill roller, it is therefore prevented that due to leading screw
There are gap between screw, so as to cause roller to be moved along the axial direction of leading screw, the gap between two rollers is improved
Precision, ensure that the accuracy and flatness of products thickness.
