The rotary platform of the hollow platform is hollow structure, and the servo motor is connected to the side, which is convenient for the installation of the gas pipe and electric wire in the smelting tool.
2, high repetitive positioning accuracy
Hollow platform adopts single-stage helical gear reduction mode to increase output torque, gear accuracy grade is lower than 5. In addition, the flexible gap adjustment mechanism controls the backlash by changing the center distance between the two gears, so the hollow turntable has a minimum clearance and the repeated positioning accuracy is less than 5 seconds.
3, high rigidity
The turntable of the hollow platform is supported by a set of precision cross roller bearings. The rollers in the bearing are arranged in 90 degrees staggered, and the diameter of the roller is slightly larger than the size of the raceway between the inner ring and the outer ring of the bearing, so that there is a pre-tight roller between the inner ring and the outer ring of the cross roller bearing. Therefore, the servo turntable supported by the bearing can withstand radial, axial, overturning torque and other torque, its stiffness is more than 10 times of the traditional bearing.
4, high rotation accuracy
After the assembly of the servo turntable, the cross roller bearing of the platform is used as the rotating center for grinding, and the outer diameter and end face of the turntable are ground again (the standard level is to complete the rotation), so as to ensure geometric tolerances such as parallelism and coaxiality of the turntable.
5. Any configuration of the motor
Hollow rotary platform can be customized flange and input shaft hole flexible interface size, suitable for connecting any brand of servo motor.
