Function:

Crane slewing reducer is an important part of the crane, its main role and function are as follows:
1. Reduce speed and increase torque
The main function of the crane slewing reducer is to convert the high speed rotation of the motor into low speed and high torque output. By means of a gearing system, the reducer is able to significantly reduce the rotational speed of the input shaft. At the same time, according to the law of conservation of power (power = torque x rotational speed), a reduction in rotational speed results in a corresponding increase in torque, provided that the input power remains unchanged. This is critical for the slewing operation of cranes, which require high torque to drive the rotation of heavy loads.
2. Achieving stable slewing motion
The slewing reducer ensures that the upper structure of the crane (e.g. lifting arm, operator's cab, etc.) is able to rotate smoothly by means of its internal gear train and bearing supports. This stable slewing motion is essential for the precise operation and safety of the crane, especially when lifting heavy objects.
3. Changing the direction of transmission
Reduction gears can also change the direction of power transmission, for example by converting the vertical rotation of the motor to the horizontal rotation of the crane's slewing mechanism. This change of direction is important for the overall layout and ease of operation of the crane.
4. Provide mechanical protection
Slewing gearboxes protect other parts of the crane by sharing the load and reducing shocks and vibrations. By absorbing and cushioning the impacts generated during operation, the gearbox reduces wear and tear on the equipment, extending service life and reducing maintenance costs.
5. Lubrication and cooling function
The lubrication system of the slewing reducer can effectively reduce the wear and tear of the internal gears and bearings and lower the temperature rise. The lubrication system usually consists of an oil pool, oil pump, oil filter and oil pipe, and sends the lubricant to each lubrication point by means of circulating oil supply to form a lubrication film and reduce friction. This not only improves the service life of the reducer, but also ensures its stability and reliability in long-time operation.
6. High bearing capacity and stability
The crane slewing reducer is made of high-quality materials and advanced technology, which has high bearing capacity and can withstand the weight of the boom and the working load. Its gear transmission system and bearing system are precisely designed and optimised, with good transmission precision and stability, which can ensure the smooth slewing of the boom.
7. Easy to install and maintain
Slewing reducer usually has small volume and weight, which is easy to install and maintain. Its sealing performance is good, which can prevent dust and moisture from entering and further extend the service life of the equipment.
