what is hollow shaft reducer?
Hansheng Automation's hollow shaft reducer is a precision transmission device that combines high rigidity and high precision, designed specifically for automation systems, robotics, precision machining, and other applications. Its unique hollow structure solves the wiring challenges of traditional reducers, replacing DD motors and cam dividers. While maintaining ±10 arc-second repeatability, it significantly reduces equipment costs and meets the requirements of 24-hour continuous operation.
Products Features
Hollow Structure
The turntable has a large hollow center, allowing for the passage of cables, piping, or other components through the axis of rotation, which is ideal for robotic arms and similar applications.
High Rigidity
These turntables are designed to support significant loads, ensuring stability and resistance to deformation even under heavy forces. This is important for accurate positioning and precision in industrial automation.
High Precision
Large-diameter rotating platforms typically offer high precision in rotation with minimal backlash, ensuring accurate and repeatable positioning.
High Torque Capacity
They are built to handle high torque loads while maintaining rotational accuracy, making them suitable for heavy-duty applications such as manufacturing or assembly lines.
Integrated Bearings
These turntables often include high-quality cross-roller bearings or similar configurations to provide smooth rotational movement and enhance stability.
Low Profile and Compact Design
Despite their large diameter, the turntables are often designed with a low profile, allowing them to be used in applications where space is limited.
Ease of Installation
The hollow structure and mounting options make them easy to integrate into various systems without complex installation procedures.
Smooth Operation
The rotating platform is typically designed for smooth and silent operation, minimizing vibrations and wear over time, which is critical for applications involving continuous operation.
Customizable Load and Speed
Depending on the application, the load-bearing capacity and rotational speed can often be adjusted or customized to fit specific needs.
Selection case
The following is a case study of a Mexican customer. We first learned about the customer's needs and application scenarios in detail. Their production line runs 24 hours a day, requiring the equipment to withstand high-intensity loads and work stably for a long time. Based on the customer's working conditions, we calculated and verified and recommended the HRT200 model.
Through this selection, we not only helped the customer improve production efficiency, but also further strengthened the trust between the two parties. This case fully demonstrates the adaptability and performance of our products in high-demand environments.

How to install this product?
How to install hollow shaft reducer?
Firstly, when customizing the mechanical equipment mounting plate, it is necessary to reserve a motor outlet and mounting hole on the mounting plate to expose the motor part of the hollow rotating platform. Secondly, as illustrated below, attach the hollow shaft reducer on the mechanical equipment mounting plate using the two positioning pin holes. The hollow shaft reducer is then securely fixed to the mounting plate using workers.(As seen below.)
How to install load on hollow shaft reducer?
To install the load, use the six mounting screw holes on the hollow shaft reducer's turntable.The turntable of the hollow rotating platform has two pin holes for installing loads, which can be utilized to locate the load. The positioning pins must be firmly fixed on the load.
How to attach motors to Hollow Shaft Reducer?
Step 1
First confirm whether the motor and turntable are in good condition.
Check whether the connection size between the motor and the rotating platform is correct, and wipe the mating surfaces of the two clean.
Step 2
Remove the original flat key on the motor.
Step 3
Determine the motor shaft diameter, If a shaft sleeve is required please install it into the force hole first and align it with the notch of the locking ring.
Step 4
Take out the plug, adjust the input shaft locking ring so that the tightening screw is aligned with the plug hole, and insert an Allen key.
Step 5
Connect the motor vertically to the rotating platform naturally, and no beating is allowed.
To prevent excessive axial force from damaging bearings or gears.
Step 6
In order to ensure uniform force, please screw up the installation screws at the diagonal position 1, 3 first, but do not tighten; then screw the two diagonal installation screws 2, 4. Finally, tighten the four mounting screws one by one.
Step 7
Tighten the screws tightly. If there are two holding screws, please tighten them evenly and symmetrically.
Step 8
Replace the plug.

FAQ
Q: What is the specific function of the hollow hole in a hollow shaft reducer?
A: Hollow holes are primarily used for internal wiring, air pipes, or drive shafts, especially in automated production lines. They prevent cable entanglement and interference with rotational motion, simplifying equipment design. For example, in a robotic workstation, control cables and pneumatic lines can be routed through the hollow hole, making the overall layout more compact.
Q: Does different mounting methods (horizontal, vertical, or suspended) affect load capacity?
A: It does. For horizontal mounting, the load capacity is the rated value. For vertical mounting, the additional stress of gravity on the bearings must be considered, and the load is recommended to be no more than 80% of the rated value. For suspended mounting (such as inverted mounting), the load should be controlled within 60% of the rated value due to the combined effects of gravity and torque. Therefore, the mounting method should be specified in advance when selecting a model.
Q: What causes abnormal noise during operation? How can it be resolved?
A: Common causes include: ① Insufficient lubrication (adding special gear oil will suffice); ② Excessive misalignment between the motor and reducer shafts during installation (recalibrate the installation position to ensure coaxiality ≤0.1mm); ③ The load exceeds the rated value (a higher torque model is required); ④ Bearing wear (contact after-sales service for bearing replacement).
Q: What is the product warranty period? What does after-sales support include?
A: The standard warranty period is 20 months (from the date of receipt), and non-intentionally damaged parts are replaced free of charge during the warranty period.
Q: How can I test whether the positioning accuracy of a hollow shaft reducer meets the standard?
A: We recommend using a laser interferometer or a high-precision goniometer: Mount the test device on a turntable and repeatedly position the same angle multiple times. Record the deviation each time. If the maximum deviation is ≤±10 arc seconds (for the HRT200JS model), the accuracy standard is met.
