PLANETARY VIBRATOR OF DIRECTED VIBRATIONS Russian patent published in 2024 - IPC B06B1/16 

FIELD: vibration equipment.

SUBSTANCE: invention relates to vibration equipment, namely to devices for obtaining directed mechanical vibrations. Planetary vibrator of directed vibrations is made in the form of a gear-planetary vibration exciter, includes cylindrical housing 1 with covers 2, 3, inside of which there is cassette 5 with toothed crown gears 9, 10 and races 11, 12 located with the possibility of turning the housing around axis 4 and locking by retainers 33. In the proposed solution, inside cassette 5 there is a kinematically rigid frame 13, which includes in-series connected in bearing support assemblies 14, 15, 16, 17 unbalance shaft 18, starting load balancing shaft 19, carriers 20, 21. Carriers 20, 21 are made in the form of double-arm levers with sides of smaller and larger length at the ends, in which on smaller sides 14, 15 unbalanced shaft 18 is installed, and on larger sides 16, 17, starting load balancing shaft 19 with synchronization gear wheels 28, 29 engaged with crown gears 9, 10 in the plane of satellites 23, 27. At that, one carrier 20 is connected by permanent connection with drive shaft 30, which is installed in bearing unit of end cover 2, and drive. Other carrier 21 is connected by a permanent connection to shaft 31 installed in the bearing assembly of other end cover 3. Rotary device 32 and retainers 33 are fixed on cylindrical housing.

EFFECT: increasing the reliability and efficiency of the planetary vibrator of directional oscillations and increasing the stability of its operation by reducing starting torques.
