Hollow Rotary Platform Reducer Application and Features

Introduction: The hollow rotating platform is currently a blank space on the market. It directly replaces the cam divider and DD motor. The hollow rotating platform is a digital positioning rotary platform with high positioning accuracy. It has the advantages of low cost and high precision, and it occupies the category of rotating platforms. Strong market.

One, hollow rotary platform reducer six purposes

1. Load inertia change

2. High precision positioning

3. Apply inertia weight

4. High-precision positioning using hollow holes

5. The use of hollow hole optics

6. Suction hollow hollow platform reducer with suction hole

Second, the rigidity of the hollow rotary platform reducer

Different types of output platforms use different types of bearings. Mounting dimensions 60mm models with deep groove ball bearings (2), 85mm and 130mm models use cross roller bearings. The larger the model number, the greater the allowable inertial load. On the contrary, it can reduce the displacement of the inertial load.

Direct connection → simple design to enhance the reliability of the hollow rotating platform reducer, the device can be directly installed on the table and the robot arm. When the general equipment is positioned and operated by means of pulleys and other mechanical parts, it is mostly affected by the transmission efficiency of the mechanical parts and the accuracy is reduced, or there is a need to maintain the parts of the mechanism. The DG series can be installed directly without intermediate parts. Therefore, in addition to the direct use of the accuracy of the product itself, maintenance can be eliminated.

Large-diameter hollow rotating platform → Concise wiring and piping Due to the use of a reduction gear mechanism to increase the diameter of the driven gear, a large-diameter hollow hole (through-hole) design is realized. It is suitable for drawing complicated wiring and piping, which makes the equipment design more concise.

Third, the hollow shaft rotating platform is a series of planetary servo reducer

The use of high-rigidity crossed-inclined roller bearings provides an integrated design with the rotating platform surface, which can withstand large-capacity disc devices, and the entire group is equipped with a stepper motor and a driver.

Fourth, characteristics

1. Direct Link: Easy Design Improves Reliability.

2. Large-diameter hollow rotating platform: simple wiring and piping

3. Accurate positioning

4. Short-term positioning: The inertial load can be positioned in a short time.

5. Simple Origin Regression: Eliminate the hassle of design and parts procurement

Fifth, the hollow shaft rotation platform can replace the DD motor and the splitter, achieving a balance between the two. Repeat positioning accuracy ≦ 5 seconds, the motor is easy to prepare, load stable, can be used with AC servo motor or stepper motor to do any angle segmentation, both to meet the digital controller can not reach the control, positioning accuracy is comparable with DD motor. Can greatly reduce costs and bring you unexpected results!

Product use occasions are as follows:

Widely used in aerospace, military equipment, semiconductor equipment, medical equipment, robots, robots, communications equipment, pharmaceutical equipment, printing equipment, packaging machinery,

1. Bearings supporting rotating platforms: Types of bearings used for rotating platforms.

2. Permissible torque: Use acceleration torque or load fluctuation below this allowable torque.

3. Inertia inertia: The total of inertial inertia of the motor part and inertial inertia of the deceleration mechanism part converted by the rotating platform.

4. Resolution: This means the number of pulse waves required for one revolution of the rotating platform.

5. Repeated Positioning Accuracy: Shows how much error occurs when the same position is repeatedly positioned from the same direction.

6. Positive and negative reversal angle error: It means that when the rotary platform is positioned at a certain position from the forward rotation direction, the rotation angle is different from the stop angle at the time of positioning from the reversal direction.

7. Angle transmission error: means the difference between the logical operation angle of the rotary platform calculated from the input pulse number and the actual operation.

8. Permissible thrust load: It indicates the allowable axial load tolerance from the direction of the axis of the rotary platform.

9. Permissible inertia load: When the load is applied to the center eccentric position of the rotating platform, the force of tilting the rotating platform will appear. The value calculated from the center-to-offset amount×load at this time means the allowable value of the inertial load.

10. The degree of parallelism of the rotary table means the inclination of the mounting surface of the rotary table with respect to the device-side mounting surface of the actuator.
