(54) MULTI-TRAFFIC TILT DRIVE CONVERTER

The invention relates to ferrous metallurgy, specifically improves the design of the converter tilt drive. Known multi-motor tilt converters l. The closest to the invention is a drive that includes a low-speed gearbox mounted on the trunnion of the converter's support ring, high-speed mounted gearboxes and electric motors mounted on the frame, mounted on the trunnion shafts of the gears of the low-speed gearbox, as well as a damper device when using these drives Converter shops of Chelinsky, Karaganda, Lipetsk and other meta-jilgichesky factories revealed the following shortcomings: considerable weight, and hence the inertia of the mounted on a single frame X-speed gears and motors to be damping NIJ significantly complicate the constr tion dampers and does not lead to an optimum operation mode tilt actuator as a whole, large dimensions and ve. high-speed mounted gearboxes and electric motors greatly complicate their installation and disassembly, requiring additional devices such as a hydraulic washer, mounting blocks / these disadvantages are especially pronounced when trying to create one-sided tilt drives for large-capacity converters with a capacity of 350-400 tons. facilitate installation and disassembly, weight reduction and improved processability. For this purpose, each support frame is provided with trunnions that enter the bores of the low-speed gearbox housing and are connected to the gearbox housing by an adjustable screw tension, while the electric motor shafts are connected to the input shafts of the high-speed mounted spindle reducer. FIG. Figure 1 shows a four-motor tilt drive with removed high-speed gearboxes and supporting frames with electric motors, a general view of J in FIG. 2 - the same, with the upper motor-reducer groups removed / in FIG. 3 - fastener unit supporting rff1, top view. The device includes a housing 1 of a low-speed mounted gearbox, in

which is mounted on bearings a hollow shaft 2 with a fixed gear 3 fixed on it, engaging with gear-shafts 4 mounted in the bores of housing 1 on bearings 4. At the ends of shafts of gears 4 fixed gears 5 that engage into mounted on bearings in the bores of housing 1 with shaft-shaft gears 6. Gear pairs, consisting of wheels 5 and shaft-gears b, are protected by detachable covers 7 mounted in bearings on shaft rollers. At one of the ends of the shafts of the tester, high-speed mounted gearboxes 8 are mounted, the housings of which are kept from turning by damping mouths and). 9. Supporting frames

10 with the electric motors 11 mounted on them and the brakes 12 are provided with trunnions 13 entering the bores 14 made in the housing 1 of the low-speed reducer and connected to the housing 1 by adjustable screw rods 15. All electric motors

11 are connected to the input shafts of the mounted high-speed gearboxes 8 universal and spindles 16. The case I of the low-speed outboard gearbox is connected to the fixed bed 17 while holding the device 18.

The device works as follows

The electric motors 11, mounted on the supporting rails 10 fixed to the copus 1 of the low-speed reducer, transmit through the spindles 16 the rotation to the input shafts of the high-speed mounted reducer 8. This will result in the rotation of the gear shafts 6 which are engaged with the gear wheels 5. Gear shafts - gears 6 and gear wheels 5, made with a tilt angle, form a split chevron engagement. When the gears S rotate, gear shafts 4 rotate, the gear 3 rotates before rotation, which transmits this rotation to the hollow shaft 2, and the latter rotates the trunnion of the converter's support ring (not shown), ensuring the inclination of the converter housing fixed on the ring. The housing 1 of the low-speed tilt-drive reducer prevents the restraint device 18 from propping, and the keeping of the fast-moving gearboxes 8 from KopiiycoB's rotation and the damping of these gearboxes is carried out by the damping devices 9. The angular movements of the housings of the high-speed gearbox 8 relative to

fixedly mounted motor 11 is compensated by spindles 16.

Placement of motors and brakes on fixedly zakrelSle hydrochloric in a low-speed gear housing frame and connecting them through the spindle with high-speed half gear significantly reduces the weight and inertial mass of the hinged speedboat-motor group consisting speedboat hinged reducer and motor podutezhaschy damping, uprsntsaet damping devices and considerably simplifies the assembling , dismantling of the high-speed motor-reduction group and improves the operating conditions of the drive as a whole.

Embedding an additional gear pair in the form of a forked chevron into the body of a low-speed gearbox increases the drive capacity of the drive, which reduces the size and weight of the high-speed mounted gearbox.

These advantages make it possible to create one-sided tilt drives for large-capacity converters with a capacity of 350-400 tons, which gives an annual economic effect in the amount of 350 thousand rubles (according to the calculations made in the Organization for the price).

This effect is determined by reducing the weight of the equipment, improving processability, operating conditions, as well as reducing the size of the converter as a whole. ,
