The rotary table of the hollow rotary platform is a hollow structure, and the servo motor is connected on the side to facilitate the installation of gas pipe and wire in the smelting tool.
High repeat positioning accuracy
The hollow rotating platform adopts the single-stage helical gear deceleration mode to increase the output torque, and the gear accuracy grade is below grade 5. In addition, the flexible clearance adjustment mechanism controls the side clearance by changing the center distance of the two gears, so that the empty return of the hollow rotating platform is minimal and the repeated positioning accuracy is below 5 arc seconds.
The rotary table of the hollow rotary platform is supported by a set of precision cross roller bearings. The rollers in the bearing are staggered at 90 degrees, and the roller diameter is slightly larger than the raceway size between the inner and outer rings of the bearing, so that there is a preload between the inner and outer rings of the cross roller bearing and the rollers. Therefore, the rotary table of the servo rotary platform supported by the bearing can bear various moments such as radial, axial and overturning, Its rigidity is more than 10 times that of traditional bearings.
High rotation accuracy
After the servo rotary platform is assembled, take the cross roller bearing of the platform as the rotation center, and grind the outer diameter and end face of the rotary table again (the standard level is finish turning) to ensure the geometric tolerances such as coaxiality and parallelism of the rotary table.
Any configuration of motor
The hollow rotating platform can flexibly change the size of the interface by customizing the flange and input shaft hole, which is suitable for connecting any brand of servo motor.
