Hollow structure
The rotary table of the hollow rotating platform is of hollow structure, and the servo motor is connected at the side, which is convenient for the installation of gas pipes and wires in the metallurgical tools.
High repeat positioning accuracy
The hollow rotating platform adopts single-stage helical gear deceleration to increase the output torque, and the gear accuracy level is below level 5. In addition, the flexible gap adjustment mechanism controls the side clearance by changing the center distance of the two gears, so that the hollow rotating platform's air return is very small, and the repeated positioning accuracy is below 5 arc seconds.
High rigidity
The rotary table of the hollow rotating platform is supported by a set of precision cross roller bearings. The rollers in the bearings are arranged in a 90 degree staggered way, and the roller diameter is slightly larger than the raceway size between the inner ring and the outer ring of the bearing, so that there is a preload between the inner ring and the outer ring of the cross roller bearing and the rollers, so that the rotary table of the servo rotating platform supported by the bearings can bear various moments such as radial, axial and overturning, Its rigidity is more than 10 times that of traditional bearing.
High rotation accuracy
After the assembly of the servo rotating platform, the cross roller bearing of the platform is taken as the rotating center, and the outer diameter and end face of the rotary table are grinded again (the standard level is precision turning), so as to ensure the 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 and stepping motor.
