Technical solution of the present utility model can also realize like this: ratchet (15) is installed on the driving shaft (4) by key (18), and ratchet (16) is assemblied on the ratchet (15) by pin (17).
Technical solution of the present utility model can also realize like this: the shape of casing (10) can be a cuboid, also can be cylinder.
Compared with prior art, the utlity model has following beneficial effect:
1, adopts the friction type ratchet mechanism can transmit the power of driving shaft, can utilize its one-way only operation performance to regulate direction of excitation again.
2, the control method of direction of excitation is simple and reliable, and adjustable range is big, can regulate in 0～360 ° of scope.
3, direction of excitation can be adjusted at any time according to need of work, thereby increases the working range of vibratory equipment, improves its service behaviour and operating efficiency.This utility model can be used on dull and stereotyped rammer or the vibration rolling rammer waits on some compacting equipments.In a plurality of fields such as this utility model also can be widely used in building, builds the road, water conservancy, agricultural, mine.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is the structural representation of synchromesh gear and ratchet.
Fig. 3 is Fig. 2 E-E cutaway view.
Fig. 4 is the dial schematic diagram.
Embodiment:
Referring to Fig. 1 and Fig. 2, the utility model mainly is made of pulley concial disk 1, bearing 2, eccentric block 3, driving shaft 4, driving gear 5, driven gear 6, eccentric block 7, driven shaft 8, eccentric block 9, bearing 11, bearing cap 20, bearing cap 21, ratchet 15, ratchet 16, casing 10, bearing 12 etc.
The bottom of casing 10 is equipped with bearing 12, and the middle part of casing 10 is equipped with driving shaft 4 and driven shaft 8.Pulley concial disk 1, bearing 2, eccentric block 3, driving gear 5, ratchet 15 are installed on the driving shaft 4 successively; Bearing 11, eccentric block 9, eccentric block 7, driven gear 6 are installed on the driven shaft 8 successively.
Referring to Fig. 3, ratchet 15 is close to the inner chamber of driving gear 5 and is installed on the driving shaft 4 by key 18, is symmetrically installed with ratchet 16 along center line by pin 17 in the outer end of ratchet 15, the inner headed face fluid-tight engagement of the flank of tooth of this ratchet 16 and driving gear 5 inner chambers.Driven gear 6 is installed on the driven shaft 8 by key 19.Casing 10 surfaces are provided with installing hole 14, use when this hole is used for being connected with Box Cover.
This utility model course of work is as follows:
During vibrator work, motor drives driving shaft 4 by pulley concial disk 1 and rotates, and drives eccentric block 3, ratchet 15 and ratchet 16 simultaneously and rotates together.Ratchet 16 on the ratchet 15 relies on the effect of friction to drive driving gear 5 and also rotates together, engagement by driving gear 5 and driven gear 6, make driven shaft 8 and driving shaft 4 do the synchronous backward rotation, and the exciting force of making a concerted effort to be of the centrifugal force that the eccentric block 3 on it, eccentric block 7 and eccentric block 9 are produced, the direction of making a concerted effort is direction of excitation.
When making vibrator produce vertical vibration, the control method of vibrator following (referring to Fig. 4):
(1) under stopped status, rotate driving shaft 4, make eccentric block 3 on the driving shaft 4 get back to initial position (eccentric block 3 be under), under the key 13 on this moment pulley concial disk 1 just in time is positioned at, align with dial " 0 " graduation mark on the bearing cap 20.
(2) keep driving shaft 4 motionless, with spanner backward rotation driven shaft 8, make eccentric block 7, eccentric block 9 on it get back to initial position, promptly " ↓ " on driven shaft 8 terminations aligns with dial " 0 " graduation mark on the bearing cap 21.When vibrator is worked like this, just can produce the exciting force of vertical direction.
When changing the vibrator direction of excitation, the control method of vibrator following (referring to Fig. 4):
(1) step 1 is with above-mentioned method.
(2) according to needed direction of excitation, backward rotation driven shaft 8 makes on arrow " ↓ " and the dial on the driven shaft 8 graduation mark of respective angles align and gets final product.For example: now need vibrator produce along with the vibration of 45 ° of directions of horizontal plane, only need driven shaft 8 counter-clockwise direction are turned over 90 °, be driven shaft 8 terminations the dial of " ↓ " and bearing cap 21 on 270 ° of graduation marks align and get final product, the total exciting force F that is produced after the vibrator work is as shown below all the time like this.
Dull and stereotyped ram or vibration rolling ram adopt the utility model after, can change direction of vibration at any time according to the difference of the material that is compacted thing or packing and compacted depth.When selecting 45 ° of direction of vibration for use, but compacting equipment just move forward voluntarily on vibrating compacting limit, limit, improved compaction capacity and operating efficiency.
