PREVIOUS LEVEL OF TECHNOLOGY

At present, the quality of the product, the reliability of the nodes, the efficiency of the operation of the rollers is not large enough. YOU ARE WORKING WITH A GOOD CHOICE ARE A MASTER BETWEEN THE COUNTRIES AND PERFUMES OF OPERATIVE ROLLS IN EXISTENCE. When picking up a metal by working importantly as a result of disposing of these rollers with a single charge, there is a risk of losing work. This results in a 15-step effort of friction at the expense of working and rolling rolls. Product rolls are deductible in the case of specified gaps between their air bags and beds, which results in an increase in good operation efficiency. This reduces the cost of up-to-20 expansion units and improved shaft shafts.

The difference in working rolls does not increase rolls, since they do not apply to them. ds of sκρuchivaniya ρabοchegο valκa οκρuzhnye sκοροsτi 25 secheniyaχ πο length egο κοnτaκτa with οπορnym valκοm οκazyva- goτsya ρazlichnymi, τοgda κaκ οκρuzhnye sκοροsτi οπορnοgο shaft-length κav secheniyaχ πο egο κοnτaκτa with ρabοchshl valκοm ποsτο- yanny due οτsuτsτviya sκρuchivaniya.

Уль As a result of this, there is a difference in the average speed of 30 working directions and the main roller for the length of their contact.

This results in a slip-resistant roller of the direct and negative contact, and in the area of their contact pressure, alternating friction forces are present.

The result of this operation and contact of 55 rolls is that the wear and tear of the rolls is uneven - 2 -

At the length of their barrels, which reduces the reliability of the work and the overall rolls.

15 The countries and the air cushion supplies are provided with interchangeable plates, which are contact between themselves, and at the same time they are in contact with the external voltage.

Since the operating rolls are also installed in parallel with the mains, there is no interruption between the operating unit and the operating unit.

However, if you use the stick, it may be subject to replacements that could result in loss of service due to loss of service

If you take up work rolls due to their loss of speed, you will experience a loss due to the installation of a single drive.

The plates on the smells of the rolls are made on the wedges, and on the beds - with the parallel faces.

Lower payments are reserved for the use of other important things on the rotors, so that the loss of service is possible during the transfer

Due to this, the angles of the ^' important stresses of the positive cells' are reduced, the axial loads of the larger parts are reduced and the load is increased. Β ρesu-

30 In addition to reducing the accrual of the operating environment and other important factors, the reduced occupational accretion and the increased accrual are reduced.

However, the transfer of plates is due to the need to extract important parts from the clutch, which results in the transfer of goods to the plate.

Otherwise, when operating the staple, it will be subject to a loss of contact with the product, which may result in damage to the product. - 4 - on the side of the gaps between the airbags of the important and the countries.

30 (in the direction of the process), dynamic loads on the lower nodes are important and improve and continue to improve. Excessive process pressure is eliminated, and the card load is significantly reduced, and the process drive is exposed to high value-added voltages.

At the same time, the wear and tear of the working efficiency of the other and the important factors is reduced due to a decrease in the strength of the drive. - 6 - not a contact, which increases the reliability of the shaft

Reducing the angles of the process is important in order to ensure that there is a better intervertebral artery disease, and, consequently, it decreases

It is advisable that there are troubles on the plaques of the cushion of important and stable parts at an angle of 1, 5-20 ° 10 ° with all the important points.

where Ρ ^ is the horizontal lower? 2 is the pulling force; ϊl. , _! „- the friction coefficients in the area of contact with the cushion 4 or 5 5 sec. Of the emergency treatment of the countries I and in the area of contact wedges, it is inconsequential.

By further decreasing Ρ _τ, they are divided by the inertial forces and the friction forces in the zone of contact with working condition 2 (Fig. 2) and an important cause of 3 (иг аз)

Studies have shown that the magnitude of the force Ρ ** -, which is transferred to the same cushion 4 or 5, does not exceed 10 of the processing force, that is, in calculating the necessary

After submission to this expression of the stated values of 20 values and derivations of the indicated expressions, we derive:

The eighth part of the left-hand side of this expression (due to the smallness of ± ₂ <0.05) is significantly less than its main part, as it should be neglected. 25 Otherwise, this assumption is an idea for the safety of keeping the cushion 4.5 in the stanzas I (decreases the _{value of τε .} ).

That is, in the end, it ensures lower dynamic load on the large and working rolls and their better nodes and better results. In this case, the angles of the working belt and external shafts and axial loads in the area of their contact are reduced, which are supported by the advanced knots of the rolls. This reduces the wear and tear of working and large rolls and increases the quality of the bill.

The working abutment of the quick-rolling mill works with the following.

Due to this, the benefits of 4 and 5 of the main rollers 3 always benefit from the I countries, which are due to the costs of the arrears between 7 and 9.

Due to the fact that the specified gaps are available, the 3-hour occupation of the working clutch makes it possible to use the appliance without any interruption and there is no need to disconnect from it.

At the same time, the more dynamic loads of 25 wheels on rollers 2 and 3 and their complementary nodes are reduced, and the reliability of these nodes is increased. Otherwise, there is a reduction in the speed of the process and 2 and 3 rolls and axial loads in the area of the drive, which leads to a decrease in the speed of the drive.

In general, the use of the proposed invention ensures an increase in the reliability of the drives due to the increase in the efficiency of the drives.

Intended use
