Imput shaft and driven shaft are installed in described casing.The first eccentric wheel is installed in described imput shaft, and stretch out outside casing through upper cover the upper end of imput shaft.The second eccentric wheel is installed on described driven shaft, and the lower end of driven shaft is arranged on base plate.In described casing, be bolted mounting flange, connection for transmission case on mounting flange, mounting teeth wheel carrier in transmission gearbox.Between described imput shaft and driven shaft, by transmission gearbox, link together.Described tooth rest upper and lower side is installed respectively a semiaxis conical gear, and imput shaft and driven shaft are respectively by semiaxis conical gear of spline joint.
Compensating-gear shaft is installed in described tooth rest, and the two ends of compensating-gear shaft are set with a planetary conical cone gear.Described planetary conical cone gear upper and lower side respectively with imput shaft on semiaxis conical gear and the semiaxis conical gear on driven shaft be connected with a joggle.
Between described semiaxis conical gear and tooth rest, be provided with bearing.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure, has met the requirement of boats and ships installing spaces, is convenient to install; Eliminate Ship Vibration source, alleviated workman's labour intensity, improved the efficiency of work.

The specific embodiment
The present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1 and 2, the present invention mainly comprises imput shaft 1, the first eccentric wheel 2, transmission gearbox 3, mounting flange 4, driven shaft 5, upper cover 6, casing 7, base plate 8, semiaxis conical gear 9, planetary conical cone gear 10, compensating-gear shaft 11, tooth rest 12 and the second eccentric wheel 14, described casing 7 lower end connecting bottom boards 8, upper end connects upper cover 6.
The interior installation imput shaft 1 of described casing 7 and driven shaft 5.The first eccentric wheel 2 is installed in described imput shaft 1, and stretch out outside casing 7 through upper cover 6 upper end of imput shaft 1.The second eccentric wheel 14 is installed on described driven shaft 5, and the lower end of driven shaft 1 is arranged on base plate 8.In described casing 7, be bolted mounting flange 4, connection for transmission case 3 on mounting flange 4, the interior mounting teeth wheel carrier 12 of transmission gearbox 3.Between described imput shaft 1 and driven shaft 5, by transmission gearbox 3, link together.Described tooth rest 12 upper and lower sides are installed respectively a semiaxis conical gear 9, and imput shaft 1 and driven shaft 5 are respectively by semiaxis conical gear 9 of spline joint.
The interior installation compensating-gear shaft 11 of described tooth rest 12, the two ends of compensating-gear shaft 11 are set with a planetary conical cone gear 10.Described planetary conical cone gear 10 upper and lower sides respectively with imput shaft 1 on semiaxis conical gear 9 and the semiaxis conical gear 9 on driven shaft 5 be connected with a joggle.
Between described semiaxis conical gear 9 and tooth rest 12, be provided with bearing 13.
Principle of work of the present invention is: when work, by 1 semiaxis conical gear in imput shaft 9, drive two planetary conical cone gears 10 that are engaged with to rotate around compensating-gear shaft 11, drive semiaxis conical gear 9 on opposite side driven shaft 5 to rotate, thereby drive relative the first eccentric wheel 2 of the second eccentric wheel 14 coaxially to rotate backward, thereby produce unidirectional level or vertical two-axle vibration exciting power, this disturbance force produces a balancing torque with the outside moment opposite direction of main frame generation of vibration, rely on this moment and outside moment balance to be offset, reach the object of eliminating Ship Vibration source.Realize navigation safety, the energy-conservation and requirement that improves crewman's comfort level, improved service life and the work efficiency of boats and ships.
The transmission of semiaxis conical gear 9 has guaranteed that the first eccentric wheel 2 and the second eccentric wheel 14 realize coaxial reverse, the box sizes of having avoided again the spur wheel driving of parallel axes to cause excessive simultaneously, inconvenient shortcoming is installed, has guaranteed the requirement of ship's space space to equipment installation dimension.
