Product Description
The hollow rotary platform is a new type of rotary load device, which combines high transmission efficiency, high precision, high rigidity, and high cost performance, and combines the advantages of servo motors, cam dividers and direct drive motors.
Use high-precision gear structure and radial bearings. Improved torque and rigidity, more stable load bearing, can be divided at any angle with servo motors or stepper motors, which can not only meet the number of control that the divider cannot achieve, but also the positioning accuracy is comparable to that of direct drive motors, and the positioning of inertial loads can be achieved in a short time.

Application
The hollow rotary platform is a high-precision, high-rigidity rotary motion mechanism that is widely used in automation equipment and precision machinery. Its core feature is the hollow shaft design, which is convenient for cables, gas or liquid lines to pass through, reduces the entanglement problem during rotation, and improves the integration and reliability of the equipment.
In the field of industrial robots, hollow rotary platforms are often used in scenarios such as joint rotation and end effector positioning to ensure precise motion control. On automated production lines, it can be used for indexing turntables, precision assembly, laser processing and testing equipment to achieve high repeatability positioning accuracy. In addition, in semiconductor equipment, medical instruments, CNC machine tools and military equipment, hollow rotary platforms meet stringent precision and stability requirements with low backlash and high load capacity.

Service
Direct connection can improve reliability and reduce costs. The workbench and robot arm that need to be installed can be directly installed on the rotating platform. Compared with the use of mechanical parts such as pulleys, the time and cost of mechanical design, parts allocation, belt state adjustment and other links can be reduced.
Motor configuration
You can freely choose stepper motors or servo motors of various brands, except for the KTN series dedicated stepper motors.
High-precision positioning without backlash
No backlash, positioning accuracy ≤15sec, and repeated positioning accuracy can reach ±5sec.
Large-diameter hollow structure
Wiring and piping are more convenient and simple, and this feature is particularly prominent in wiring and piping environments with complex wiring.
