Problems solved by technology

Its transmission reliability is poor, transmission efficiency is relatively low, the structure volume is large, the weight is heavy, and it is difficult to install and operate on the boat.
The engine and transmission mechanism are directly exposed in the air, and the noise is loud during use, and they are easily corroded by seawater when operating at sea, which seriously affects the service life of the engine and transmission mechanism

Abstract

The invention discloses an outboard engine power transmission mechanism comprising a crankshaft lower case, a waterborne reduction box, an intermediate case, and an underwater reduction box; an engine crankshaft is arranged in the crankshaft lower case, and connected with a crankshaft output wheel; the waterborne reduction box is provided with a waterborne reduction box transmission shaft through a bearing, wherein the waterborne reduction box transmission shaft is connected with a waterborne reduction box power input wheel; the underwater reduction box is provided with an oar shaft through a bearing, wherein one end of the oar shaft is connected with a propeller; a transmission shift mechanism is arranged between the waterborne reduction box transmission shaft and the oar shaft, and comprises a transmission end, an intermediate transmission shaft, and a shift end; the transmission end and the shift end are respectively connected with the waterborne reduction box transmission shaft and the oar shaft, or respectively connected with the oar shaft and the waterborne reduction box transmission shaft. Compared with the prior art, the advantages are that the outboard engine power transmission mechanism reduces a transmission space, improves transmission reliability, reduces structure volume, and reduces noise and seawater corrosion influences.

Description

technical field [0001] The invention relates to a power transmission mechanism, in particular to a power transmission mechanism of an outboard motor. Background technique [0002] At present, most of the engine propulsion devices used in small outboard motors are traditional air-cooled or water-cooled vertical motors, and their power output is relatively simple. Realize power transmission. However, horizontal engines are rarely used on outboard motors, and most of them are used on outboard motors. The power transmission mechanism is not integrated with the engine. The power output method is through a single room connection, directly connected with a horizontal shaft or with a belt ( Chain) transmission, and then through the two-stage bevel gear variable speed transmission, the underwater propeller is driven to generate horizontal propulsion to drive the boat. Its transmission reliability is poor, the transmission efficiency is relatively low, the structure volume is large,...
