What kind of bearings are used for hollow rotating platforms?

Hollow rotating platforms are generally supported by high-precision crossed roller bearings. The rollers in this kind of bearing are arranged staggered at 90 degrees, and the diameter of the rollers is slightly larger than the guide roller specification between the inner ring and the outer ring of the bearing. Only in this way can axial force be generated, so that the rolling bearing can withstand radial, tilting, etc. Class moment.

What are the characteristics of the hollow rotating platform?

1. High accuracy: The accuracy of hollow rotating platforms is often very high. The positioning accuracy is within 10 seconds and can almost reach less than 5 arc minutes.

2. High stiffness: The large turntable of the hollow rotating platform is supported by a complete set of high-precision crossed roller bearings. The rollers in the bearings are arranged in a 90-degree staggered manner, and the roller diameter is slightly larger than the raceway specification between the inner and outer rings of the bearing. Due to the size, there is a clamping force between the inner and outer rings of the crossed roller bearing and the rollers. Therefore, the large turntable of the servo rotating platform supported by the bearing can withstand various moments such as radial, axial, and overturning. Its stiffness is 10 times that of traditional bearings. About times.

3. High rotation accuracy: After the hollow rotating platform is assembled, the cross roller bearing on the platform is used as the center of rotation, and the outer diameter and end face of the large turntable are ground again (the standard grade is fine turning) to ensure the accuracy of the large turntable. Coaxiality, parallelism and other geometric tolerances.

4. High cost performance: Although the manufacturing cost of the hollow rotating platform is relatively high, its high precision and high stiffness make it relatively cost effective.

5. Hollow structure: The large turntable of the hollow rotating platform has a hollow structure, and the servo motor is connected to the side to facilitate the installation of air pipes and wires in the fixture.

6. Arbitrary motor configuration: The hollow rotating platform flexibly changes the size of the interface by customizing the flange and input shaft hole, and is suitable for connecting any brand of servo motors and stepper motors.
