A limit block is arranged in an inner drum of the fixed eccentric block, and the movable eccentric block is placed in an inner drum of the fixed eccentric block. A flange C and a flange D are connected with two ends of the fixed eccentric block respectively, a blind hole is respectively arranged inside the flange C and the flange D, and the two ends of the movable eccentric block are arranged on the blind holes of the flange C and the flange D respectively. The excitation mechanism can be applied to machinery manufacture industries.

Description

The exciting agency of vibratory roller

Technical field

The utility model belongs to a kind of component on the engineering machinery, specifically, relates in particular to a kind of exciting agency of vibratory roller.

Background technology

Mostly the exciting agency of vibratory roller is that left and right exciting agency connects composition through middle splined shaft in the market.Left and right exciting agency is all by two fixed eccentric blocks of vibrating shaft outside weldering and live and put a movable eccentric block and forms, and exciting agency is many with component, make complicated, cost height, and less reliable; This kind exciting agency is with needing in the middle of the vibrating wheels soldering member with the fixing vibration bearing of four formers, vibrating wheels soldering member complex structure, and fabrication cycle is long, the cost height.

Summary of the invention

The utility model purpose has provided a kind of exciting agency of vibratory roller, and the road roller exciting agency is made complicacy in the prior art, cost is high and the defective of poor reliability to overcome.

The utility model is realized through following technical scheme: a kind of exciting agency of vibratory roller; Comprise fixed eccentric block and movable eccentric block; Be provided with limited block in the fixed eccentric block inner core, movable eccentric block is placed in the fixed eccentric block inner core, and the fixed eccentric block two ends are connected with flange C and flange D respectively; Flange C and flange D inside respectively are provided with a blind hole, and movable eccentric block two ends are installed in respectively on the blind hole of flange C and flange D.

Bearing shell preferably is installed on the said blind hole.

Compared with prior art, the beneficial effect of the utility model is:

1, the utility model simple structure, and be convenient to tissue production.

2, the utility model can be realized high and low amplitude two states, thereby makes vibratory roller can adapt to the compacting of different roadbed better.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

In the drawings, the eccentricity excitation mechanism of vibratory roller mainly comprises fixed eccentric block 2, movable eccentric block 3, flange C1 and flange D6.Fixed eccentric block 2 is single-casting, and the centre is a steel cylinder, and eccentric part is the outer ring semicircular cylinder, and inside is cast with limited block 4, placement activity eccentric block 3 in the middle of the fixed eccentric block 2, and two ends are connected to flange C1 and flange D6 respectively; Movable eccentric block 3 is single-casting, and the centre is a semicolumn, and two ends are small column, and movable eccentric block 3 is located at fixed eccentric block 2 inside, and movable eccentric block 3 can be realized freely rotating; Flange C1 flange D6 is single-casting; Flange C1 and flange D6 outer ring are fine finishining; Axially respectively be provided with a blind hole 7; A bearing shell 5 respectively is installed on the blind hole 7, and movable eccentric block 3 two ends are movably arranged on the blind hole 7 of flange C1 and flange D6 through bearing shell 5 respectively, and bearing shell 5 has the effect of the pivoting friction that reduces movable eccentric block 3 and blind hole 7.During work, the driving shaft 8 on the flange C1 receives the driving of vibrating motor, realizes rotation, because fixed eccentric block 2 is that rigidity is connected with flange C1 and flange D6, flange C1 rotates, and fixed eccentric block 2 also rotates simultaneously.

In Fig. 6, flange C1 rotates and drives fixed eccentric block 2 rotations, and forwards position shown in Fig. 6 to; At Fig. 7, middle limited block 4 drive activity eccentric blocks 3 rotate together, and this state is realized large amplitude down.

In Fig. 8, the direction of rotation of flange C1 and Fig. 6, fixed eccentric block 2 is also pressed rightabout and is rotated.In Fig. 9, with movable eccentric block 3 contacts and rotation, this state is realized little amplitude down to middle limited block 4 in this position.

Can know by such scheme; Because fixed eccentric block 2 is built-in with limited block 4, when flange C1 rotating, fixed eccentric block 2 is along with flange C1 while forward or reverse; 3 of movable eccentric blocks rotate under the drive of limited block 4; Cooperate the high and low amplitude two states of realization with fixing eccentric 2 simultaneously, thereby make vibratory roller can adapt to the compacting of different roadbed better, greatly improved the production efficiency of road roller.
