Hollow Rotary Platform Equipped with Servo Stepping Motor Hollow Rotary Platform Reducer
PLANETX planetary reduce
Hollow rotary platform RPA200:The rotary platform reducer uses parallel shaft helical teeth and cross roller bearings to carry the load, so as to realize hollow threading, deceleration and increase the moment of inertia. This type of reducer can be directly used as a slewing support, with a slewing accuracy of less than 20 arc seconds. It is widely used in 3C electronic industry and precision machine tools. The speed ratios of the rotary platform reducer are 5, 10, 15 and 18. Other speed ratios need to be developed again. Use the motor from 50 watts to 750 watts. The frame numbers are 60, 85, 130 and 200.
Application scope of rotary platform: the rotary platform is characterized by overload, high rotation accuracy and low clearance measurement. Its product categories include shaft type and side shaft type, There are three types of right angle structures, which are mainly applicable to mechanical arms, CNC turntables, alignment mechanisms, military radars, automation, measurement and fields requiring high accuracy in experiments. Selection steps of rotary platform:
1. Select the rotary table size according to the workpiece size; 2. Determine the model according to the size of rotary table; 3. Select reduction ratio according to speed and torque; 4. Select the positioning mode according to the installation mode; 5. Select the accuracy according to the working conditions.
The hollow rotary platform can be used for:
1. Rotary worktable in production line automation transformation;
2. Rotary chuck in laser marking or engraving machine;
3. The rotation axis in the precision alignment mechanism;
4. Light load manipulator joint;
5. High precision gear direct drive;
6. High precision, high torque, high rigidity, easy to use, with high-performance closed-loop stepping motor;
The hollow rotary platform is a blank in the current market, directly replacing the cam splitter and DD motor. The hollow rotary platform is a digital rotary platform with high positioning accuracy. It has the advantage of low cost and high accuracy, and occupies a strong market in the rotary platform category
