Slewing bearing is a kind of bearing that can bear special load such as large axial load, radial load and overturning moment at the same time. Therefore, in the selection of slewing bearings in strict accordance with the calculation of data selection!
In the truck crane, excavators and other types of construction machinery, slewing bearing is the transfer turntable and the chassis between the axial load, radial load and tipping moment of the important components.
In the case of light load, it can work, and can rotate freely. However, if the case has been overloaded, especially in the maximum weight and maximum amplitude, the slewing bearing rotation difficult, the worst case may be stuck can not rotate.
When this happens, the bearing recommends that you reduce the amplitude in time, adjust the legs or move the chassis position and other methods to tilt the body to help achieve the weight of the rotary motion to complete the scheduled lifting and other operations to avoid damage to slewing bearings.
The second is the friction, for many mechanical equipment, the friction is a key factor affecting the service life, slewing bearing bearing the same. The wear caused by friction is the main factor leading to the reduction of the service life of slewing bearing.
In short, in order to ensure the normal use of slewing bearings, usually in use, we must pay attention to bearing maintenance, regular application of lubricating oil, and do not allow long-term overload of bearing operations.
