Planetary Speed Reducer - Hollow Rotary Platform, High Rigidity & Precision Cross Roller Bearings, High Repetition Positioning Accuracy Below 5 Arc Secs, Flexible Clearance Adjusting Mechanism

We are exporter, manufacture and supplier of Planetary Speed Reducer in Shenzhen, Guangdong, China.

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.
High rotation accuracy
After the assembly of the servo rotary platform is completed, the cross roller bearing of the platform is used as the rotating center, and the outer diameter and end of the turntable are aligned again.
The surface is grinded (standard level for precision turning) to ensure the geometric tolerance of the turntable such as coaxiality and parallelism.
Arbitrary configuration of motor
Hollow rotary platform can flexibly change the size of interface by customizing flange and input shaft hole, which is suitable for connecting any brand.
