Description
Technical field
This utility model relates to a kind of Marine paddle hanging device, particularly speed change Marine paddle hanging device between a kind of case.
Background technology
Existing Marine paddle hanging device is commonly used to be passed to propeller by upper and lower case gear normal direction break-in power and drives boats and ships, it is impossible to propeller with best rotating speed, greatly reduce drive efficiency.
Summary of the invention
In order to overcome drawbacks described above, the utility model proposes a kind of New Marine extension oar machine that will concatenate change speed gear box between case between upper nowel, utilize gear train, it is achieved the above speed change between nodal axisn and lower nodal axisn, so that propeller is mated rotating speed most, to obtain maximum drive efficiency.
This utility model solves the scheme that its technical problem takes: by upper box main body, the direction-variable power 90 degree of power wheel is passed to upper nodal axisn, reduce speed by change speed gear box and impart power to lower nodal axisn to obtain bigger moment of torsion, impart power to propeller to obtain high pulling torque and to mate rotating speed most again through nowel break-in 90 degree.
The beneficial effects of the utility model are: have employed change speed gear box between case, namely being easy to structure installation makes extension oar machine still be integrated, high speed motive force can be converted to again low-speed big power and provide coupling rotating speed for propeller, to obtain optimal drive efficiency, reach the beneficial effect saved energy and reduce the cost.
