Description
Technical field
The utility model patent relates to a kind of marine gearbox, relates in particular to a kind of light-duty large speed ratio marine gearbox.
Background technique
In at present of the prior art, the layout of small-power marine gearbox clutch mainly contains preposition and rearmounted two kinds; The diameter of axle that the clutch preposition structure passes the driving gear endoporus does not receive the restriction of torsion pass power; Can design thinner, can the design of gear-box reduction speed ratio is bigger under the situation in identical central, but because clutch is preposition; Hang out solution after the more emergent screw of renewal of facing renewal or use must leave gear-box slave component, maintenance and use be inconvenience all.The rearmounted structure gear case of traditional clutch is because input shaft or transmission shaft need transmitting torque and bear moment of flexure, and shaft diameter can not be too thin, can not design very big in identical central apart from situation lower tooth roller box reduction speed ratio.The rearmounted structure gear case of clutch that the torsion shaft structure is also arranged; Though reduction speed ratio can design very big relatively; But regulate the bearing play owing to all need input shaft (transmission shaft) and input end be connected firmly through turnbuckle; Hang out solution after causing replacing clutch friction plate or torsion shaft need gear-box slave component be left, mounting or dismounting are difficulty very, the maintenance inconvenience.
