What are the advantages of using hollow rotating platforms in the robotics industry? How to choose

The hollow rotating platform has the characteristics of high precision, high stability, and strong flexibility. Through motor drive, angle adjustment automation can be achieved, which can realize multi-dimensional precise motion control, thereby achieving production efficiency, reducing costs, and improving product quality.

In practical applications, it is necessary to comprehensively consider specific working conditions, number of work positions, turntable diameter, speed, load and other factors to choose the appropriate type of hollow rotating platform. It should be noted that different series of hollow rotating platform reducers (TH, THG, THM, THR, THS, THB, THD, etc.) use different support bearings, which have a certain impact on the load-bearing capacity of the hollow rotating platform for inertia moment load. Generally speaking, the larger the model, the greater the inertia moment it can withstand, but the corresponding change in inertia moment load will also be smaller.

When selecting a hollow rotating platform, multiple parameters need to be considered. So, how to choose a hollow rotating platform? First, confirm the diameter of the turntable, which includes the working face, speed, and disk load. Based on these parameters, we can preliminarily screen for suitable models and calculate the required torque, inertia, speed ratio, and matching motor power parameters, accuracy errors, and also consider whether the reserved safety factor meets the usage requirements.

The calculation formula for the options of the hollow rotating platform is mainly based on the required torque T. This torque T is obtained by adding the load torque caused by frictional impedance and the acceleration torque caused by moment of inertia, and multiplying it by a certain safety factor. The specific calculation formula is: T=(load torque [N.m]) x safety factor.

Robots are an important application area of hollow rotating platforms, which can serve as joints for robots to achieve multi axis motion control and precise positioning of robot end effectors, thereby completing more complex tasks such as high-precision assembly, welding, etc.

The application advantages of hollow rotating platforms are as follows:

1. Compact structure: Hollow structure bearings are used to make the entire equipment structure compact. Small footprint, suitable for applications with limited space.

2. Precise positioning: Using a precise control system and high-precision servo motors, it can achieve high positioning repeatability and accuracy.

3. Multi axis motion: It can achieve multi axis motion, including horizontal rotation, tilt rotation, and vertical rotation.

4. High load-bearing capacity: The heavy-duty hollow rotating platform is suitable for application scenarios that require carrying heavy objects and precise control, and can achieve large loads without significant deformation and vibration.

The application of hollow rotating platforms in robot systems can effectively improve the flexibility and accuracy of robot movements. By using precision hollow rotating platforms of different sizes and load-bearing capacities, various models and sizes of robots can be realized, which is very useful for robots that require visual monitoring and data collection, such as photography robots or patrol robots.
