Marine outboard motor

Abstract

The invention provides a marine outboard motor which comprises a casing, a bracket, a motor body, a spindle, a control handle assembly, an output device, a controller and a water pump. The motor body and the controller are fixedly connected in the casing, the output device is connected and assembled with the casing, the motor body is in drive connection with the output device through the spindle, and the control handle assembly is connected and assembled with the casing. The control handle assembly comprises a rotary handle, a connecting handle, a connecting rod and a potentiometer; one end of the connecting handle is fixedly connected with the casing, one end of the rotary handle sleeves the other end of the connecting handle, one end of the connecting rod is fixedly connected with the rotary handle, and the potentiometer is connected and assembled with the connecting handle and electrically connected with the controller. The motor body is provided with a cooling passage, the controller is also provided with a cooling passage, and the cooling passage of the motor body, the cooling passage of the controller, the water pump and a connecting pipeline form a cooling system. The marine outboard motor is simple in structure, good in reliability and convenient to assemble and mount. The motor body and the controller are prevented from being burnt out even when a ship runs astern for a long time.

Description

technical field [0001] The invention relates to a marine oar hanger. Background technique [0002] At present, if the motor and controller of the traditional propeller hanger are not cooled during operation, the motor and controller will heat up, causing the motor and controller to burn out. Usually, the motor and controller are cooled by water cooling, as described in patent 200810195977.8. The patented water-cooled motor is connected to the main shaft, and the main shaft is used to provide power to control the water flow to cool the motor and controller. However, when the ship reverses, the motor will reverse, and the water will not be sucked into the motor and controller. If it lasts for a long time Reversing the time will cause the motor and controller to burn out.

[0002] At present, if the motor and controller of the traditional propeller hanger are not cooled during operation, the motor and controller will heat up, causing the motor and controller to burn out. Usually, the motor and controller are cooled by water cooling, as described in patent 200810195977.8. The patented water-cooled motor is connected to the main shaft, and the main shaft is used to provide power to control the water flow to cool the motor and controller. However, when the ship reverses, the motor will reverse, and the water will not be sucked into the motor and controller. If it lasts for a long time Reversing the time will cause the motor and controller to burn out

[0003] At present, the control handles of most paddle machines use mechanical transmission to control the speed of the motor boat through sensors when controlling the speed, and when reversing, they also use the reversing cable control sensor to drive the motor to reverse. This structure is relatively Complicated, poor reliability, cumbersome installation and maintenance
