Dynamic motors connect.
The beneficial effects of the present invention is：
1) present invention arranges limited impression on movable eccentric block, then when the movable eccentric block is by the limit on spacing ring
When position projection is fixed on vibrating shaft, because the central angle of limited impression is more than the central angle of the spacing block set, then work as vibration
During axle difference positive and negative rotation, movable eccentric block occurs two due to two kinds of cooperation positions of limited impression therein and spacing block set
Limit station is planted, so as to movable eccentric block is presented two kinds of vibrational states when vibrating shaft distinguishes positive and negative rotation.
Limited impression is set on movable eccentric block because the present invention is simply simple, so as to greatly simplify structure,
Manufacture and the installation difficulty of eccentric block are reduced, simultaneously because the movable eccentric block in the present invention is global formation, therefore is used
When be hardly damaged, operationally maintain higher stability and reliability.
It is of course also possible to arrange spacing block set on movable eccentric block, and limited impression is set on spacing ring, same energy
Realize two kinds of vibrational states.
The present invention can be provided only with movable eccentric block group on vibrating shaft, be existed by multiple different movable eccentric block groups
The distribution of vibrating shaft and formed adapt to engineering site needs superpositing vibration.
2) the movable eccentric block group in the present invention is arranged independently of one another with fixed eccentric block group, because movable eccentric block is shaking
Two kinds of vibrational states are presented during moving axis difference positive and negative rotation, it is Chong Die with the end face of both fixed eccentric blocks so as to work as movable eccentric block
When more, integrally there is larger exciting force in vibrator；When movable eccentric block it is Chong Die with the end face of both fixed eccentric blocks less
When, integrally there is less exciting force in vibrator, so as to movable eccentric block group and fixed eccentric block group are fitted to each other, realizes big
The transformation of small vibration state.
The simultaneously central angle variable-angle of the limited impression on movable eccentric block, it is this it is variable both can be eccentric by activity
The structure design of block and cause limited impression size it is adjustable, so as to the central angle angle of limited impression is changed, it is also possible to
By the different polylith activity eccentric block of the central angle angle for designing a series of limited impression, and pacified according to on-site actual situations
The movable eccentric block of the different central angle angles of dress, so that vibrational state of the movable eccentric block on vibrating shaft is changed,
It is final that the vibrational state of vibrator is changed.
3) movable eccentric block group and the fixed eccentric block in the present invention has multiple combination mode, such as movable eccentric block group with
Fixed eccentric block group can stick together to form superposed type design, it is also possible to be spaced segment distance formation separate type and set
Meter；When movable eccentric block group and fixed eccentric block composition are designed from formula, it is preferred to use symmetrical version.
Movable eccentric block group in just because of the present invention has in multiple combination, therefore the present invention with fixed eccentric block group
The position of eccentric block is different from the spacing middle part for being arranged in vibrating shaft of existing eccentric block, so as to the activity in the present invention partially
The Distributed Design of heart block group and/or fixed eccentric block group can greatly reduce the load of vibrating shaft in vibration, while
Load and impact of the vibration of vibrating shaft to two ends vibration bearing is significantly reduced, so as on the basis of vibrating effect is ensured
The service life of vibration bearing is substantially prolongs, while also significantly reducing the fault rate of the parts in vibrator.
4) when vibrating shaft is set to two, two vibrating shafts are symmetrical in vibrator housing；When vibrating shaft is arranged
For four when, the circumferencial direction of four vibrating shafts along housing axis in vibrator housing is uniformly distributed.Also it is exactly of the invention
In movable eccentric block group and/or fixed eccentric block group Distributed Design so that the movable eccentric block group on many vibrating shafts
And avoid each other between fixed eccentric block group without occurring interfering, so as to the arrangement in the present invention is not only able to fully
Using the space in vibrator housing, and can realize that vertical vibration, level are shaken under positive and negative two kinds of rotary states of vibrating shaft
Three kinds of different directional vibrations of dynamic, oblique vibration, while the exciting force size under every kind of directional vibration state can also be adjusted, by
This enables vibrated roller to better adapt to the section of different roadbed, drastically increases the production efficiency of road roller.
