Rotary table bearing is a kind of large-scale bearing with a special structure, which can bear large comprehensive loads such as axial load, radial load and overturning moment at the same time, and integrates multiple functions such as support, rotation, transmission and fixation.
Its function is to connect the upper and lower parts of the machine, support the weight of the upper part and the load generated during the operation of the machine, and rotate the upper part of the machine relative to the lower part (or the lower part relative to the upper part).
This type of bearing is used on a variety of occasions, of which important applications are in the transportation industry, agricultural trailers, irrigation systems and airport luggage racks. In-vehicle applications, the axial load, radial load and torque of the bearing are transmitted. In other applications, they mostly transfer axial loads.
Wind turbine bearings usually include yaw bearing, pitch bearing and transmission system bearing (main shaft and gearbox bearing). The yaw bearing is installed at the connection between the tower and the cabin, and the pitch bearing is installed at the connection between the root of each blade and the hub. One set of yaw bearings and three sets of pitch bearings are used for each wind turbine.
Rotating solar panels are a good solution to increase energy.
High precision, low noise, high service life and high-reliability series of rotary bearings of the main shaft and rotary table of medical devices have been widely used in large medical devices such as gamma knives, CT machines and nuclear magnetic resonance machines.
industrial robot and other equipment. The turntable bearing is installed at the joint of the robot, and this structure can realize incredibly high close rotation movement.
