Application
1. Lifting machinery
Lifting machinery includes truck cranes, tower cranes and trailers,
etc. Due to the harsh environment of these machines, the rotating
parts are often subject to great impact, so these parts will use
customized slewing bearings, such as for The manufacturer provides
the required size of the machine and the operating environment. The
slewing bearing manufacturer will arrange the engineer to design
the suitable bearing according to the actual situation, and then
put it into use, which can not only meet the needs of the hoisting
machinery, but also greatly improve the service life.
2. Construction machinery
The simple division of construction machinery is like excavators,
loaders, etc. The slewing bearing can bear axial force, radial
force and overturning force at the same time, and the structure is
very compact. It needs to be rotated continuously during the
operation of the excavator. The slewing bearing is the core
component of rotation. The application of construction machinery
belongs to the basic application of slewing bearing, and it is also
widely used.
3. Processing machinery
Processing machinery like material processing, food processing,
metallurgy and so on. With the continuous development of science
and technology, people are no longer satisfied with only applying
slewing bearings in construction machinery, and turn their
attention to equipment platform processing machinery. Because the
slewing bearing is more compact than the original bearing, the
external force can also be larger, and the performance and
structure are better, so it is also widely used in processing
machinery.
4. Military equipment
The current military competition is about the hard power of
military equipment. As we saw on TV, the tank turns its cannon
head, and a shell hits the target accurately. In this link, the
slewing bearing plays a very good supporting role; There are also
anti-aircraft guns, radars, rocket launch pads, etc., a very
important structure in the timely rotation, jump and stable launch
of military equipment is the slewing bearing, which has better
performance than traditional bearings.
5. Other
In addition to being used in industry and medicine, the slewing
bearing has its shadow in the field of power generation and life.
The yaw bearing of the wind turbine is installed at the connection
between the tower and the cockpit, and the pitch bearing is
installed at the root of each blade. connection with the wheel hub.
Each wind turbine uses one set of yaw bearing and three sets of
pitch bearing. Through the application of the slewing bearing on
the wind power generation equipment, the process of generating
power can be changed by the difference of the wind force. The main
applications of slewing bearings in life are concentrated in
playgrounds, such as Ferris wheels, roller coasters, pendulum
clocks and merry-go-rounds, etc. The application of slewing
bearings ensures the safety of life.
