The invention relates to the processing of bulk materials in vibratory machines and can be used in the mining, metallurgical, coal and other sectors of the industry for dispersing and transporting materials.

The purpose of the invention is to increase operational reliability and durability by reducing the load on the bearings.

FIG. 1 shows the composite liners 10 and 12, the elastic sleeve 11 on the housing 7 of the bearing assembly and bead 2 of the duct 1. Under the action of these forces, the duct 1 together with the sieve 3 oscillates spontaneously at the springs 13. As a result of the oscillatory motion, dispersion of transported material. For each rotation of the shaft there is a consistent deformation of the sections of the elastic element between the outer 10

cops support inertial screen; Yu and 12 inner liners.

and in fig. 2 - inertial screen with a stretch-the presence of an elastic element between the aged

vibrator bearing unit. The screen consists of a spring-loaded box 1 with sides 2, between which a sieve 3 is fixed. The unbalance shaft 4 with debalances 5 is in the pipe 6, rigidly connected to the housing 7 of the bearing assembly, attached to the sides of the box. The unbalance shaft bearings 8 are placed in a cylindrical cup 9, on the outer surface of which there are fixed 20 outer liners 10 which are located along its forming 10 cup. the inner surface is the inner liners 12, mixed with half the angular pitch relative to the outer liners, are fixed to the housing sockets. Thus, the elastic sleeve 11 is located between the bearing housing 7

Kan 9 and housing 7 bearing assembly several times reduces the load on the bearings and thus ensures the reliability and durability of the bearing assembly. The absence of viscous resistance forces in the elastic ring increases the effectiveness of reducing the loads acting on the bearing assembly.
