What are the characteristics of the hollow rotating platform?

The turntable of the hollow rotating platform is a hollow structure, and the servo motor is connected to the side, which is convenient for the installation of the gas pipe and the wire in the jig.

The hollow rotating platform with high repeatability positioning accuracy uses a single-stage helical gear reduction method to increase the output torque. The gear accuracy level is below 5, plus a flexible adjustment mechanism. The backlash is controlled by changing the center distance of the two gears, making the hollow The empty return of the rotating platform is extremely small, and the repeat positioning accuracy is below 5 arc seconds.

The turntable of the high-rigidity hollow rotary platform is supported by a set of precision cross roller bearings. The rollers in the bearing are staggered by 90 degrees, and the diameter of the rollers is slightly larger than the size of the raceway between the inner ring and the outer ring of the bearing. There is a pre-tightening force between the inner and outer rings and the rollers of the sub-bearing. The servo rotating platform turntable supported by the bearing can bear various moments such as radial, axial and overturning, and its rigidity is more than 10 times that of traditional bearings.

After the high rotation accuracy servo rotating platform is assembled, the outer diameter and end face of the turntable will be ground again with the cross roller bearing of the channel as the center of rotation (standard grade is fine turning) to ensure the coaxiality and parallelism of the turntable Equal form and position tolerance.

The hollow rotating platform with any motor configuration can flexibly change the size of the interface by customizing the flange and input shaft hole, which is suitable for connecting servo motors and stepping motors of any brand.
