Description

The invention relates to a vibration technique and can be used in various sectors of the national economy as a variable vibration machine.

The purpose of the invention is to increase reliability by balancing the unbalances during starting and stopping due to their mutual reversal.

FIG. 1 shows a vibration exciter, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 is a kinematic diagram of a cam clutch.

The vibration exciter comprises a rotational drive 1, a housing 2, shafts 3 parallelly disposed therein, synchronized

180 ° to position b, and the unbalances are thereby unfolded to an agreed position. The vibration exciter generates a linear periodic disturbing force. When stopped, the drive 1 of rotation and the controlled norm are simultaneously turned on; minimum closed brake 15. In this case, brake 15 inhibits rotation of shaft 6 and driven gear kinematically connected to it 11. Under the action of inertial 10 forces, drive 1, shaft 3 with unbalances 5 continue rotation and twist elastic element 12 through drive pin 10, until the cams 13 and 14 rotate 180 ° to position a. In this case, unbalances 5 are deployed relative to

among themselves gears 4, from rigidly zak-debalans 8 on 180 ° in the mismatched

repositioned on them debalans 5 and shafts 6, position. When the exciter is turned off, the gear 11 is braked by the normally closed brake 15, and the overrunning clutch 16 prevents the gears 7, synchronized with each other by gears 7, with unbalances fixed on them 8. The turn of 180 shafts of unbalances of 5 shafts 3 relative to unbalances of 8 shafts 6 20 12 and thereby provides a cam clutch, the misaligned position is maintained

in the form of an axis 9, freely set-unbalances 5 relative to unbalances 8.

the spindles of gear 10 which are attached to it, sv –when repeated switching on and off with one of the gears 4,, and all, the vibration exciter works in a similar way,

home gear 11 associated with one of a balanced position

gears 7. Leading gears 10 and debalances due to their mutual spreading gears 11 are interconnected; the company eliminates dynamic loads during

an elastic element 12 in the form of a spring inlet and stop of the vibration exciter and twist and have cams 13 and 14 facing each other, respectively, of the cams 13 and 14. The driven gear 11 through gear 7 and the shaft 6 is kinematically connected to the controlled normally closed brake 15, and the leading gear 10 is connected with overrunning clutch 16, hard wearing down thereby its reliability.

Invention Formula set on axis 9. The vibroactivator, comprising a case, two pairs of parallel, parallel-synchronized ones located in it. The vibroactivator operates in the following way, with unbalances fixed on them, a cam clutch designed During start-up, the rotational drive 1 and the controlled normally closed brake 15 are simultaneously turned on. This releases the shafts 6. From drive 1 to rotate 180 ° of one pair of shafts relative to the other, and drive rotation of the shafts, characterized in that, in order to increase reliability, the cam clutch after transmission 17, shaft 3 and gear-40 is complete as an axis, freely mounted 4 rotation is transmitted to the drive gear 10, which cam 13 acts on cam 14 of driven gear g 11 and transmits rotation to shafts 6. The elastic element 12 is in a twisted state, the cams are position a, the unbalances 5 are mismatched relative to the unbalances 8 by 180 ° and the disturbing with sludge is not generated. At steady state operation, under the action of a swirling elastic element 12, the cams 13 and 14 turn on 45 50 associated with one of a pair of driving and driven gears, which have cams at the ends, periodically interacting with each other, and connecting between the driving and driven gears of the elastic element, and the exciter is equipped with a normally closed brake, kinematically connected connected with the driven gear, and overrunning clutch rigidly mounted on the axle and connected with the pinion gear. 180 ° to position b, and the unbalances are thereby unfolded to an agreed position. The vibration exciter generates a linear periodic disturbing force. When stopped, the drive 1 of rotation and the controlled norm are simultaneously turned on; minimumly closed brake 15. At the same time, brake 15 inhibits rotation of shaft 6 and driven gear kinematically connected to it 11.
