In fact, hollow rotating platform and planetary reducer are a reducer, is a new rotating load device, hollow rotating platform set high efficiency, high precision, high rigidity, high price in one, integrated the advantages of servo motor, CAM splitter and direct drive motor.

Hollow rotating platform using high precision gear structure and radial bearing, improves the torque and rigid, handing down more stable, tie-in servo motor or stepper motor can be done at any Angle, can satisfy the divider can't realize digit control, its positioning precision and can be comparable to a direct-drive motor, can realize the positioning of the inertial load in a short time.

Another term for hollow rotating platform
Hollow rotating platform can also be called servo hollow rotating platform, high precision rotating platform, hollow shaft rotating platform, hollow rotating platform reducer, motor hollow rotating platform.

Advantages of hollow rotating platform

1. Through direct connection can improve reliability, reduce costs
the workbench and mechanical arm that need to be installed can be directly installed on the rotating platform. Compared with the use of belt wheels and other mechanical parts, the hollow rotating platform can reduce the time and cost of mechanical design, parts allocation, belt state adjustment and other links.

2. Motor configuration
Optional stepper motor or servo motor.

3. High positioning without backlash
No backlash, positioning accuracy is less than or equal to 1MIN, repeated positioning accuracy can reach plus or minus 5 arc seconds.

4.large diameter hollow structure
Wiring, pipe more convenient and simple, in the wiring complex wiring, pipe environment, the advantage of this feature is particularly prominent.

Characteristics of hollow rotating platform
1. Hollow structure
The rotary table of the hollow rotary platform is hollow structure, and the servo motor is connected to the side to facilitate the installation of the air pipe and wire in the mould.

2. high repetitive positioning accuracy
Hollow rotary platform with the method of single-stage spiral gear reduction to increase the output torque of the motor, gear precision grade hollow rotating platform below level up to 5, with its flexible adjustable gap organization, by changing the way the two gear center distance to control the lateral clearance, empty back to tiny hollow rotating platform, the repetitive positioning accuracy under 5 arc second.

3. hollow rotating platform of rotary table is supported by a set of precision cross roller bearing, bearing of the staggered roller is 90 degrees, and roller diameter slightly larger than between the bearing inner ring and outer ring raceway size, cross roller bearing inner and outer ring and roller, prestressing force between the bearing support of servo turntable rotating platform to withstand radial, axial and overturning moment, Its rigidity is more than 10 times that of traditional bearings.

4. high rotation accuracy

After the assembly of the servo rotating platform, the cross roller bearing of the platform is used as the rotating center to grind the outer diameter and end face of the turntable again (the standard grade is fine turning) to ensure the coaxiality, parallelism and other shape and position tolerances of the turntable.

5. motor arbitrary configuration

The hollow rotary platform can flexibly change the interface size through customized flange and input shaft hole, suitable for connecting servo motors and stepper motors of any brand.
