Classification and scope of slewing ring
Add Time:2014-11-15 14:37
Slewing ring is the most important mechanical parts, there are two races overall composition, compact, light weight, ball and raceway four point contact bearings with a strong force, radial force and tilting moment, in all art can be used.
      Slewing ring structure type classification:
      Single-row four-point contact ball slewing bearing: Single-row four-point contact ball slewing ring consisting of two races, compact, light weight, ball four point contact with the arc rolling road, can withstand the axial force, radial force and tilting moment.
      Single row cross roller slewing bearing: Single-row crossed roller slewing ring, consisting of two races, compact, light weight, high manufacturing precision, small assembly space for installation high precision roller 1: a cross arrangement, can withstand the axial force, tilting moment and larger radial forces.
      Three-row roller slewing ring: three-row roller slewing ring has three seat, down and radial raceways each separately so that each row roller load can be determined exactly. Able to withstand all kinds of loads, is the product of the maximum carrying capacity of a shaft, the radial dimensions are large, solid structure.
      Double Reducing ball slewing bearing: double-row slewing bearing has three seat, ball and isolation blocks can be directly discharged into the upper and lower raceway, according to the situation by force, arranged two rows of different diameter steel balls. This assembly is very easy to open, carrying angle of both the upper and lower arc raceway is 90 °, can withstand large axial forces and tilting moments.
      Light series slewing ring: Light slewing bearing slewing rings have the same general structure, light weight, flexible rotation.
      Slewing bearing purposes:
      1, trailer: This type of bearings used in a variety of occasions, the most important applied transportation industry, agricultural trailers, irrigation systems and airport luggage rack. Application of the vehicle, passing the bearing axial load, radial load and torque. In other applications, most of them are passed axial load. Jinyuan professional manufacturer of trailer with rotating bearing.
      2, robots: industrial robots and other equipment. Kim Won-mounted slewing bearing joints of the robot, this structure can achieve incredible high close rotary motion.
      3. Medical Devices: Jinyuan bearing developed high precision, low noise, high life, high reliability series of medical devices bearing spindle rotation, has been widely used in Gamma Knife, CT machines, MRI machines and other large medical equipment.
      4. Solar energy: solar panels rotate is a good increase in energy solution. Because Jinyuan bearing has a very compact design, supply, Europe’s largest solar farm.
      5. Wind: Wind turbine bearings usually contain the yaw bearing, pitch bearings, transmission bearings (main shaft and gearbox bearings). Jinyuan provide customers the yaw bearings and pitch bearings. The connecting portion of the tower with a yaw bearing is mounted in the cockpit, the pitch bearing is installed with the hub at the root portion of each blade is connected. Each wind generator with a yaw bearing and three pitch bearing.
