hollowed areas

The turntable of the hollow rotary platform is hollow structure, and the servo motor is connected to the side, which facilitates the installation of the gas pipe and wire in the metallurgical tools.

High repetition positioning accuracy

The hollow rotary platform adopts single-stage helical gear deceleration to increase the output torque. The gear accuracy level is less than 5, plus

Flexible clearance adjusting mechanism can control backlash by changing the center distance between two gears, so as to make the hollow rotary platform return to the pole.

Small, repetitive positioning accuracy is below 5 arc sec.

High rigidity

The turntable of the hollow rotating platform is supported by a set of precision cross roller bearings. The rollers in the bearings are staggered at 90 degrees, and

Roller diameter is slightly larger than the raceway size between the inner ring and outer ring of the bearing, which makes the inner and outer ring of the cross roller bearing and between the rollers exist.

In the pre-tightening force, the servo rotary table supported by the bearing can withstand various torques such as radial, axial and overturning.

Rigidity is more than 10 times that of traditional bearings.
