How extensive are the main uses of slewing bearings

2020-05-20

The slewing bearing itself has the advantages of compact structure, convenient correct guidance and rotation, simple installation and easy maintenance. It is widely used in heavy machinery and equipment, mining machines, construction machinery, port machinery, wind power generation, medical equipment, radar detection and On large and medium-sized rotating equipment such as cruise missile launchers, in addition, the slewing bearing can bear a relatively large radial load, axial load and collapse torque and other comprehensive loads, including support plates, rotation, transmission systems, and stationary. A large bearing with a special structure acting on the body.

Subsequently, the key function of the slewing bearing is to connect the upper and lower left and right components of the equipment, and the net weight of the upper member and the load caused by the supporting point of the equipment during operation, so that the upper member of the equipment rotates relative to the lower member. And the main uses of slewing bearings are very common, such as:

1. Trolley: This type of rolling bearing is used for a variety of main purposes, among which the key is transportation industrial production, agriculture and animal husbandry, sprinkler irrigation system and airport luggage rack. In the use of the car, the radial load, axial load and torque of the rolling bearing are transmitted. In other applications, they key to transmit radial loads. LZK manufactures rolling bearings for carriages.

2. Wind power generation: Wind energy generator rolling bearings generally include yaw rolling bearings, aircraft propeller rolling bearings, and drive system software rolling bearings (machine tool spindles and transmission rolling bearings). LZK presents yaw rolling bearings and pitch rolling bearings for customers. The yaw rolling bearing is installed at the connecting part of the tower body and the cab, and the variable aircraft propeller rolling bearing is installed at the root of each leaf and the connecting part of the rim. Each wind energy generator uses a set of yaw rolling bearings and four sets of pitch rolling bearings.

3. Solar power generation: rotating solar photovoltaic panels is a good way to increase kinetic energy. LZK rolling bearing has a very compact design scheme, showing the electrostatic field of solar power generation in Europe.

4. Medical equipment: high-precision, low-noise, long-life, and sales electricity price medical equipment spindle bearing slewing bearing series products developed by LZK rolling bearings are used in large and medium-sized medical equipment such as gamma knife, CT machine, and magnetic resonance machine. .

5. Intelligent robots: industrial manipulators and other machinery and equipment. The turntable bearing is installed on the joints of the intelligent robot, and its design plan is to maintain unimaginable inseparable rotation.

In addition to various engineering machinery and equipment, the use of slewing bearings has gradually expanded. Seaport machinery, metallurgical equipment, offshore drilling platforms and other machinery and equipment have also just begun to use slewing bearings on a large scale to replace the original rolling bearings.
