The internal structure of an electric winch usually consists of core modules such as power components, deceleration and force increasing components, brakes, output mechanisms, input mechanisms, drum and wire rope systems, control and protection devices, etc. The following is a detailed explanation:

Power components:

Motor: The core power source of an electric winch, usually using an electric motor (such as a variable frequency motor, DC motor, etc.), which converts electrical energy into mechanical energy to drive the winch to operate. The motor has a speed regulation function, which can adjust the speed and torque according to the load demand, achieving low-speed start under heavy load and high-speed operation under no-load.

Deceleration and force boosting components:

Reducer: located between the motor and the drum, it reduces the speed and increases the torque through gear transmission (such as double arc gears, cycloidal pinwheels, worm gears, etc.), allowing the drum to wind the steel wire rope at a lower speed and with greater force. The design of the reducer directly affects the transmission efficiency and load-bearing capacity of the winch.

Brake:

Braking device: used to control the start and stop of the winch, ensuring the safety of the equipment during operation. Brakes are usually divided into manual and automatic types, using structures such as hydraulic disc brakes or electromagnetic eddy current brakes, which can quickly brake in emergency situations and prevent equipment from losing control.

Output organization:

Chain wheel, gear or pulley: transmits the power of the reducer to the drum, driving the drum to rotate. The design of the output mechanism needs to consider transmission efficiency and reliability to ensure smooth and impact free power transmission.

Input institution:

Coupling: connects the motor and reducer, transmits torque, and compensates for installation errors. Couplings usually use couplings with brake wheels, which facilitate the installation and maintenance of the brake.

Drum and wire rope system:

Drum: a component for winding steel wire rope, which achieves the winding and unwinding of the steel wire rope through rotation. There are usually rope grooves on the drum to increase the friction between the steel wire rope and the drum, preventing slippage.

Steel wire rope: a key component that connects the drum and the load, withstands tension and transmits power. The selection of steel wire rope needs to consider factors such as its breaking force, wear resistance, and corrosion resistance.

Control and protection devices:

Control box: It contains control components such as PLC and frequency converter, which realize the functions of starting, stopping, speed regulation, and braking of the winch. The control box also has fault diagnosis and protection functions, such as overload protection, short circuit protection, etc.

Sensors and monitoring devices: used to monitor the operating status of the winch, such as speed, torque, temperature and other parameters, to ensure that the equipment operates within a safe range.
