Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of marine engine bumper coaxial reverse mechanism is provided, compact conformation is convenient to install, and can eliminate the Ship Vibration source, alleviates labor strength, and can increase work efficiency.
According to technical scheme provided by the invention; Marine engine bumper coaxial reverse mechanism mainly comprises imput shaft, first eccentric wheel, transmission gearbox, mounting flange, driven shaft, upper cover, casing, base plate, semiaxis conical gear, planetary conical cone gear, compensating-gear shaft, tooth rest and second eccentric wheel; Said casing lower end connects base plate, and the upper end connects upper cover.
Imput shaft and driven shaft are installed in the said casing.First eccentric wheel is installed on the said imput shaft, and the upper end of imput shaft is passed upper cover and is stretched out outside casing.Second eccentric wheel is installed on the said driven shaft, and the lower end of driven shaft is installed on the base plate.Through the bolted connection mounting flange, connect transmission gearbox on the mounting flange in the said casing, mounting teeth wheel carrier in the transmission gearbox.Link together through transmission gearbox between said imput shaft and the driven shaft.Said tooth rest upper and lower side is installed a semiaxis conical gear respectively, and imput shaft is connected a semiaxis conical gear through spline respectively with driven shaft.
Compensating-gear shaft is installed in the said tooth rest, and the two ends of compensating-gear shaft are set with a planetary conical cone gear.Said planetary conical cone gear upper and lower side respectively with imput shaft on semiaxis conical gear and the semiaxis conical gear on the driven shaft be connected with a joggle.
Be provided with bearing between said semiaxis conical gear and the tooth rest.
Compared with present technology the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure, has satisfied the requirement of boats and ships installing spaces, is convenient to install; Eliminate the Ship Vibration source, alleviated working strength of workers, improved the efficient of work.

The specific embodiment
Following the present invention will combine the embodiment in the accompanying drawing to further describe:
Shown in Fig. 1 ~ 2; The present invention mainly comprises imput shaft 1, 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 second eccentric wheel 14; Said casing 7 lower ends connect base plate 8, and the upper end connects upper cover 6.
In the said casing 7 imput shaft 1 and driven shaft 5 are installed.First eccentric wheel 2 is installed on the said imput shaft 1, and the upper end of imput shaft 1 is passed upper cover 6 and is stretched out outside casing 7.Second eccentric wheel 14 is installed on the said driven shaft 5, and the lower end of driven shaft 1 is installed on the base plate 8.Through bolted connection mounting flange 4, connect transmission gearbox 3 on the mounting flange 4, mounting teeth wheel carrier 12 in the transmission gearbox 3 in the said casing 7.Link together through transmission gearbox 3 between said imput shaft 1 and the driven shaft 5.Said tooth rest 12 upper and lower sides are installed a semiaxis conical gear 9 respectively, and imput shaft 1 is connected a semiaxis conical gear 9 through spline respectively with driven shaft 5.
In the said tooth rest 12 compensating-gear shaft 11 is installed, the two ends of compensating-gear shaft 11 are set with a planetary conical cone gear 10.Said planetary conical cone gear 10 upper and lower sides respectively with imput shaft 1 on semiaxis conical gear 9 be connected with a joggle with semiaxis conical gear 9 on the driven shaft 5.
Be provided with bearing 13 between said semiaxis conical gear 9 and the tooth rest 12.
Principle of work of the present invention is: when work; Driving two planetary conical cone gears 10 that are engaged with star gear wheel shaft 11 that detours through 1 semiaxis conical gear on the imput shaft 9 rotates; Drive semiaxis conical gear 9 rotations on the opposite side driven shaft 5; Thereby drive second eccentric wheel, 14 relative first eccentric wheel, 2 coaxial backward rotation, thereby produce unidirectional level or vertical twin shaft disturbance force, this disturbance force produces an outside moment balancing torque in the opposite direction that produces with the main frame vibration; Rely on this moment and outside moment balance to be offset, reach the purpose of eliminating the Ship Vibration source.Realize navigation safety, the energy-conservation and requirement that improves crewman's comfort level, improved the service life and the work efficiency of boats and ships.
The transmission of semiaxis conical gear 9 has guaranteed first eccentric wheel 2 and second eccentric wheel, 14 realization coaxial reverses; The box sizes of simultaneously having avoided the spur wheel driving of parallel axes to cause again is excessive; The shortcoming of inconvenient installation has guaranteed the requirement of ship's space space to the equipment installation dimension.
