The slewing bearing itself has the advantages of compact structure, convenient rolling and correct guidance, 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 relatively large radial load, axial load and collapse torque and other comprehensive loads, including support plates, rolling, transmission systems, and stationary. A large bearing with a special structure acting on the body.
The slewing bearing also occupies a very important part in people’s daily life and industrial production. It is widely used. I think the important thing is that because its application has dealt with many difficulties in the mechanical manufacturing industry, because the slewing bearing has no teeth, external Several structural forms such as tooth type and internal tooth type touch ball bearings, single and double row angular capacity ball bearings, crossed cylindrical roller bearings, crossed deep groove ball bearings and three-row cylindrical roller bearing combined bearings, etc. In the meantime, the ball slewing bearing has a higher static load capacity; the crossed cylindrical roller bearing has a higher dynamic load capacity; the crossed deep groove ball bearing can make the rolling bearing have a large support plate rigidity according to the pre-clearance cooperation And high rotation precision, therefore, it has been used in the application of construction machinery and equipment.
Subsequently, the important effect of the slewing bearing is to connect the upper and lower left and right members of the equipment, and the gross 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 rolls relative to the lower member. And the main uses of slewing bearings are very widespread, for example:
1. Trolley: This type of rolling bearing is used for a variety of main purposes, among which is the transportation of industrial production, agriculture and animal husbandry, sprinkler irrigation systems and airport luggage racks. In the use of the car, the radial load, axial load and torque of the rolling bearing are transmitted. In other applications, they mainly transmit radial loads. LZK manufactures rolling bearings for carriages.
2. Wind power generation: Wind power 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: Rolling 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 electricity-priced 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 the incredible inseparable rolling.
In addition to all kinds of construction machinery and equipment, the use of slewing bearings is also gradually expanding. Seaport machinery and equipment, metallurgical equipment, offshore drilling channels and other machinery and equipment have also just begun to use slewing bearings on a large scale to replace the original rolling bearings.
