The reducer of a crane plays a vital role in accessories. The reducer is a mechanical device that converts high-speed rotating force into low-speed rotating force. It is usually composed of gear transmission. In a crane, the function of the reducer is to reduce the high-speed rotating force output by the main motor so that it can adapt to the low-speed and high-torque working environment required by the crane. Therefore, the reducer can be said to be one of the key components for the normal operation of the crane.
First of all, the importance of the reducer is reflected in the following aspects:
1.
Provide the torque and speed required by the crane: Cranes usually need to work under ultra-high weight, so they need to have sufficient torque. The reducer can reduce the speed of the main motor in exchange for greater torque output. In addition, when the crane is performing lifting, lowering, telescoping and other processes, it is also necessary to achieve just the right speed adjustment. The reducer can reduce the speed output by the high-speed motor to the required range to meet the different working requirements of the crane.
2.
Realize transmission and reverse control: The reducer uses the principle of gear transmission to achieve transmission through multi-stage reduction. The crane needs to flexibly control its forward and reverse rotation during work, and the design of the reducer can ensure stable transmission and reliable reversal under different working conditions.
3.
Protect the main motor: The main motor of the crane often has high power and needs to withstand a large load. The reducer can effectively disperse the load and reduce the working pressure of the main motor, extending its service life.
4.
Improve the working efficiency of the crane: The reducer can improve the transmission efficiency of the crane through reasonable design according to the needs of mechanical parts. This effective energy conversion can not only reduce energy loss, but also improve the working efficiency of the crane.
