Description

Electric outboard engine anode block mounting structure

Technical Field

The utility model relates to an electric outboard engine, in particular to an anode block mounting structure of the electric outboard engine.

Background

At present, many electric outboard engines adopt underwater motor-driven propellers, and the materials of the motors are mainly as follows: the iron, aluminum and copper are easy to be corroded by seawater and oxidized in underwater motors, so that the motor performance is low and even the motor is seriously disabled, and the problem that the motor is oxidized needs to be solved.

In the prior art, the anode block is arranged on the motor shell, so that the surface of the motor is protected. However, the motor and the rotating shaft are exposed to the outside, and the rotating shaft material is generally stainless steel, but in sea water, the rotating shaft is conducted into the motor through the rotating shaft, so that the inside of the motor is oxidized.

And meanwhile, under the operation of a high-power motor, the propeller can bear great axial force and rotating force, and displacement can easily occur. In the prior art, as shown in fig. 1, a locating pin A is adopted to penetrate a nut B to locate a propeller C, the operation of locating holes is ensured in the installation process, gaps are ensured between the nut and the propeller, abnormal sound is generated due to shaking of the gaps in the operation process of a motor, in an outboard engine with high motor power, the propeller has great rotating force when turning in water, and the locating pin is easy to deform or break.
