empty area The rotary table of the hollow rotary platform is a hollow structure, and the servo motor is connected to the side to facilitate the installation of gas pipes and lines in the melting tool. High repeat positioning accuracy The hollow rotary platform adopts a single-stage helical gear reduction mode to increase the output torque, and the gear precision grade is lower than grade 5.In addition, the flexible gap adjustment mechanism controls the side gap by changing the center distance of the two gears, so the empty return of the hollow rotary platform is minimal, and the repeat positioning accuracy is less than 5 seconds. high rigidity The rotating table of the hollow rotating platform is supported by a set of precision horizontal roller bearings.The rollers in the bearing are staggered at 90 degrees, and the diameter of the rollers is slightly larger than the raceway size between the inner and outer rings of the bearing, so that there is a pre-loaded roller between the inner and outer rings of the horizontal roller bearing.Therefore, the rotary table of the servo rotary platform supported by bearings can withstand various moments such as radial, axial and overturning, and its rigidity is more than 10 times that of traditional bearings. high rotational accuracy After assembling the servo rotary platform, grind the cross roller bearing of the platform as the center of rotation, and grind the outer diameter and end face of the rotary table again (the standard level is to complete the rotation) to ensure the parallelism of the rotary table with coaxiality and other geometric tolerances . Any configuration of the motor The hollow rotary platform can flexibly change the size of the interface by customizing the flange and the input shaft hole, and is suitable for connecting any brand of servo motor.
