FAQ:

1. How to choose a suitable hollow rotating platform based on the load weight?
     First calculate the total load weight including fixtures and workpieces. Distinguish three load types: axial load (vertical force), radial load (horizontal force), and overturning moment (eccentric force). Calculate the overturning moment by multiplying load weight by eccentric distance[reference:0]. Then compute required torque using total inertia and acceleration. Select a platform whose rated output torque exceeds the total demand by a safety factor of 1.5 to 2.0. Check manufacturer's load rating charts.

2. What is the load holding capacity of the hollow rotating platform?
     The load holding capacity refers to the static holding torque or braking torque. It maintains the platform's position when the motor de-energizes. The motor's electromagnetic brake provides this function. For critical applications, manufacturers offer mechanical brakes that directly lock the output flange for greater safety and holding force. When selecting, verify that the holding torque meets or exceeds the system's requirements.

3. What is the difference in selection criteria between dynamic and static loads?
    Static load applies when the platform remains stationary. It equals the weight of the platform plus the supported object Dynamic load occurs during rotation or acceleration. It creates inertial forces and shock loads. Always consider both when selecting a platform. Static load determines the basic capacity. Dynamic load, combined with speed and acceleration, determines the required torque and bearing life. Dynamic loads often exceed static loads due to acceleration forces.

4. Which type of transmission is recommended for a rotating platform under high load conditions?
    For high load conditions, choose a planetary gear system or a heavy-duty worm gear. Planetary gears provide high torque density, rigidity, and efficiency[reference:9]. Heavy loads may require additional planetary reducers to increase output torque. Some high-capacity platforms use 30:1 reduction ratios with axial load capacities up to 200 kg. Integrated motor-platform units with cross-roller bearings also deliver high output torque and handle heavy loads effectively.

5. What are the load testing standards for hollow rotating platforms?
    Standards include GB/T 228.1-2021 for static load testing (150% of maximum working load, permanent deformation ≤0.2%). Fatigue life assessment requires ≥10⁶ cycles. Torque testing at 120% of rated torque with efficiency loss ≤3%. Manufacturers also test bearing wear (maximum 0.3 mm) and temperature rise (≤40°C). ISO 14122-3 and GB/T 3811 apply for structural safety. Always request test reports from your supplier.
