Abstract

The invention discloses a marine engine impeller shaft assembly which includes a shaft body and an impeller, one end of the shaft body is a head end, the other end of the shaft body is a tail end, anoptical shaft is arranged between the head end and the tail end, the outer end surface of the optical shaft is provided with a plurality of ventilation grooves which are recessed in the optical shaft,the connecting end of the shaft body and the impeller is the head end, the outer side of the head end is provided with a connecting end, the connecting end is in the form of a sleeve tube, the outerside end surface of the connecting end is provided with external threads engaging with the internal threads of an impeller disc through hole, the connecting end is introduced into the through hole toform threaded connection fixation, the inner side of the connecting end is a cavity, and a plurality of reinforcing ribs are arranged in the cavity. In the above manner, the present invention can provide a heat dissipation and ventilation function, and a sleeve connecting end is arranged at the connecting part with the impeller to be connected with the impeller instead of the shaft body, thereby facilitating removal and replacement.

Description

technical field [0001] The invention relates to the field of marine engine accessories, in particular to a marine engine impeller shaft assembly. Background technique [0002] The impeller shaft is the rotating shaft used to fix and support the impeller. Applied in various fields. In the prior art, when the engine is running, the rotating shaft is used as a force transmission tool. When the engine is running, the rotating shaft is also running at high speed, and the rotating shaft that has been running at high speed for a long time has a large degree of wear. The traditional impeller shaft has the function of ventilation and heat dissipation. When the shaft body runs at high speed, the surface temperature will rise, and the connection end with the impeller will wear after long-term disassembly and use, and the whole shaft body needs to be replaced. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a ship engine ...
