Description

(54) DISINTEGRATOR DRIVE

one

The invention relates to a grinding technique and can be applied to fasten engines of high-speed grinding aggregates, for example, disintegrators.

Known fastening drive disintegrator, including mounting rotors on the intermediate shafts, lying on rigid supports and connected to the engine using couplings 1.

The disadvantages of such a drive are the complexity of the system, the large dimensions of the unit, the need for additional bearings, and an increase in energy loss. Due to the occurrence of significant inertia forces, the under-bearing is quickly worn out.

Closest to the present invention is a disintegrator drive comprising electric motors connected to the shafts of the rotor baskets, whose housings are connected to the foundation 2j through the beds.

The disadvantages of this drive are low durability, reliability and increased demands on the balance of the rotor due to the dynamic instability of the rotor-shaft-motor system. The unbalance of the rotor, resulting, for example, due to its uneven wear, causes large dynamic loads on the shaft and on the engine bearings, since the rotors are mounted on the shafts of the cantilever, and the point of application of inertial forces is far from the front bearing.

The purpose of the invention is to increase the durability and reliability of the disintegrator by reducing the dynamic loads on. shaft and engine bearings, as well as reducing vibration and noise.

This goal is achieved by the fact that in the drive of the disintegrator containing electric motors connected to the shafts of the rotor baskets, the housings of which through the beds are connected to the foundation, each electric motor is provided with an additional support plate attached to its body with a cantilever and an elastic support placed between the additional support plate and bed, with the cantilever end of the support plate pivotally connected with the st2020 NOY.

FIG. 1 shows a disintegrator, general view, section; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2. The disintegrator comprises a housing 1, baskets 2, mounted on the shaft 3 of electric motors 4. The latter are attached to an additional support plate 1 M 5, which are joined in the cantilever part by means of hinged joints 6 with a frame 7. The plates 5 rest on elastic supports 8, which have adjusting bolts 9. Fastening drive disintegrator works as follows. The electric motors 4 rotate the rotors 2 in opposite directions. From the unbalance of the rotors 2, rotating vectors of inertia arise. The elastic stops 8 and the hinged attachments of the base 7 allow the axles of the engines 4 to make small circular motions that remove loads from the shafts 3 and the bearings. The proposed mounting of the disintegrator is based on the elastic mounting of the engines, which allows reducing the dynamic loads on the shafts and their bearings and thereby increasing the reliability and service life of these structural elements, as well as reducing the level of vibration and noise during the operation of the disintegrator. The elastic mounting of the actuator allows an automatic balancing device to be used in the disintegrator.
