I believe everyone has a basic understanding,Slewing bearingIts own structure is compact, easy to guide and rotate, easy to install and simple to protect. It is widely used in lifting and transporting machinery, mining machines, construction machinery, port machinery, wind power generation, medical equipment, radar and missile launchers In addition to these large-scale reversing equipment, the slewing bearing can also withstand greater axial load, radial load and overturning moment than its own. It is a specific summary of the load, which integrates support, rotation, transmission, and fixation. Specially structured large bearings with integrated functions.
At the same time, the slewing bearing not only has this important position in our daily life, but also has an extremely important position in industrial production. The main reason why it is widely used is that its use can be solved quickly. Many problems in the construction machinery industry. Because the reversing support has four-point touch ball bearings without gears, external gears and internal gears, double-row angular touch ball bearings, crossed cylindrical roller bearings, crossed tapered roller bearings and three-row cylindrical roller combined bearings The four-point touch ball reversal bearing has a higher static load capacity; the crossed cylindrical roller bearing has a higher dynamic load capacity; the crossed tapered roller bearing has a higher dynamic load capacity through pre-interference energy. With large supporting rigidity and high reversal accuracy, the use of turntable bearings in construction machinery has been widely promoted.
The important role of the slewing bearing is to connect the upper and lower parts of the machine, support the weight of the upper part and the load generated when the machine is working, and make the upper part of the machine rotate relative to the lower part.
