What loads are generally borne by slewing bearings

　　Slewing bearingThe equipment can accept many loads, such as large axial load, radial load and overturning moment. It is a large bearing with a special structure that integrates support, rotation, transmission, fixing and other functions. No matter it Whether it is in the process of working or not working, it will accept the working load, such as self-weight load, slope load, bump load, temperature load and so on. There are many types of slewing bearings, generally divided into single-row four-point contact ball slewing bearings, double-row reducing ball slewing bearings, single-row cross-roller slewing bearings and so on. The following is a simple analysis of the load of various slewing bearing equipment.
The first is the operating load, which means that the slewing bearing equipment receives the component of the machine itself during the operation, and the sum of the weight of the increased weight, and slowly transfers the total component to the slewing bearing equipment.
There is also a temperature load, which refers to a certain temperature of mechanical equipment during operation, and the temperature of these parts will be absorbed by the slewing bearing equipment, which allows the slewing bearing to accept these temperatures.
At the same time, there are wind loads. When machinery is operating in an open environment, we need to consider the effects of wind loads, including wind direction, rain, thunderstorms and so on.
The above is only a part of the load accepted by the slewing bearing equipment. In fact, the slewing bearing equipment needs to accept more loads to meet the weight and load of the machine in operation.
Under normal circumstances, the slewing ring bearing itself is equipped with device holes, lubricating oil and sealing equipment, which can meet the different requirements of the operation under various conditions and various types of hosts.
