Description

due to the creation of additional oscillation frequency. In case 1 a drive shaft 4 is placed, on which perpendicular to its axis of rotation a shaft 7 is installed with an unbalance 8 placed on it. Shafts 4 and 7 are interconnected by a hyperboloid transmission, for example, a hypoid gear. On the shaft 7, faceplates 11 and 12 are fixed, in which an additional shaft 15 is placed with the possibility of rotation parallel to the shaft 7 with the unbalance 16 placed on it. Together with the shaft 15, gears 17 and 18 are engaged, meshed with wheels 19 and 20, are full on the shaft bearing housing 7. When the drive shaft 4 is rotated, the satellite 9 of the planetary gear, rolling on the center wheel 10 mounted on the housing 1, rotates the shaft 7 with the unbalance placed on it 8. With the rotation of the face plates 11 and 12 mounted on the shaft 7, using planetary gears the shaft 15 rotates with the unbalance 16 placed on it. The rotating unbalances 8 and 16 excite a spatial disturbing force. 3 il.

The invention relates to a vibration technique and can be used in vibratory machines for technological purposes, for example for separating materials

The purpose of the invention is the expansion of operational capabilities due to the introduction of an additional oscillation frequency.

Fig. 1 shows a vibration exciter, longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 - possible trajectory of movement of the vector of disturbing force.

The vibration exciter comprises a drive shaft 4 placed in housing 1 by means of bearings 2 and 3, in which perpendicular to its axis of rotation in bearings 5 and 6 a shaft 7 is installed with an unbalance 8 placed on it. The drive shaft 4 and shaft 7 are connected between each other, a planetary tipballball gear, for example a hypoid one, consisting of a satellite 9 mounted on a shaft 7 and rigidly fixed to the body 1 of a central wheel 10 on the shaft 7. On the shaft 7 are located the face plates 11 and 12a in which Parallel 7 installed dopol weight shaft 15 seconds with balance 16 placed on it.

Together with shaft 15, gears 17 and 18 are made at both its ends, which are satellite planetary satellites

gears, central wheels 19 and 20 of which are made on the housings 21 and 22 of bearings 5 and 6.

The vibration exciter works as follows.

A motor (not shown) rotates the drive shaft 4 at a certain angular velocity with. At the same time, the satellite 9 is rolling around relative to the central wheel 10, rotates the shaft 7 with the unbalance 8 placed on it with the angular velocity CO ,. With the rotation of the faceplates 11 and 12 mounted on the shaft 7, the gears 17 and 18, rolling around the central wheels 19 and 20, rotate the additional shaft 15 with the unbalance 16 placed on it. The rotating unbalances 8 and 16 excite the spatial disturbance force that moves the object along the corresponding trajectory (Fig. 3).
