A Cycloidal Gearbox, also known as a Cycloidal Gearbox, is a type of power transmission equipment widely used in industry due to its high load capacity and high efficiency. When combined with an electric motor, this gearbox forms a geared motor, specifically heavy-duty geared motors. It effectively increases torque and reduces the output speed. With its special design and optimized operating principle, this equipment is suitable for many applications requiring high durability and precision.

Structure of Cycloidal Gearbox

The Cycloidal Gearbox (also known as an eccentric shaft gearbox) has a more distinctive structure compared to conventional gearboxes. It is designed based on the pin-cycloid disc drive mechanism, effectively reducing rotational speed and increasing torque. The main components include:

• Input Shaft: Directly connected to the electric motor, typically designed eccentrically to transmit motion to the cycloidal disc.
• Cycloidal Disc: This is the characteristic component of the gearbox, with a special shape that creates slow and stable rotational motion.
• Pins (or Needle Bearings): Arranged around the cycloidal disc, they transform eccentric motion into the rotational motion of the output shaft.
• Output Shaft: Receives rotational motion from the pin-cycloid disc system and transmits it to the load.
• Gearbox Housing: Made of cast iron or cast aluminum alloy, it protects the entire drive mechanism and helps reduce vibration and noise.
• Bearings and Oil Seals: Help reduce friction, increase durability, and prevent oil leakage during operation.

Operating Principle of Cycloidal Gearbox

A Cycloidal Gearbox operates based on the principle of eccentric drive between the input shaft and the cycloidal disc. When the input shaft rotates, it transmits motion to the eccentric shaft, causing the cycloidal disc to rotate and precess around the center of the pin ring.

During this process, the holes on the cycloidal disc engage with the pins or stationary needle bearings around it, creating a difference in rotational speed between the input and output shafts. This difference effectively reduces the output rotational speed while significantly increasing torque.

Thanks to this principle, the cycloidal gearbox achieves a large reduction ratio in a compact size, operates smoothly, stably, and has high shock load capacity - making it highly suitable for mechanical systems requiring high precision and efficiency.

Classification of Cycloidal Gearboxes

Classification by Number of Stages:

• 1-Stage Cycloidal Gearbox: This is a simple power transmission gearbox with only one reduction stage. The 1-Stage Cycloidal Gearbox stands out with its compact design, easy installation, and high working efficiency. It offers a reasonable price and is suitable for drive systems requiring moderate speed reduction, limited installation space, and stable long-term operation.
• 2-Stage Cycloidal Gearbox: Designed with two consecutive reduction stages, this type provides a larger reduction ratio and higher torque. Thanks to its excellent load capacity and durable operation, the 2-Stage Cycloidal Gearbox is commonly used in industrial production lines, heavy machinery, long conveyor systems, or equipment requiring continuous operation with heavy loads.

By Mounting Type:

• Horizontal Shaft Type: Input and output shafts are parallel, easy to mount on machine bases or fixed frames.
• Vertical Shaft Type: Input and output shafts are perpendicular, suitable for confined spaces or vertical conveyor systems.
• Flange Mount Type: Compact design, often used for direct mounting with an electric motor.

Advantages of Cycloidal Gearbox

A Cycloidal Gearbox is highly valued for its unique structure and superior transmission capabilities, offering numerous advantages over traditional gearboxes:

• High transmission efficiency: achieving 90-95%, thanks to the continuous force transmission mechanism through multiple contact points, which reduces energy loss.
• Compact size - high load capacity: with its unique cycloidal design, the gearbox can handle 3-5 times the load compared to conventional types of the same power, while maintaining a small size and light weight.
• Smooth and low-noise operation: the sliding-rolling structure of the cycloidal disc helps reduce vibration and noise during operation, suitable for environments requiring low noise levels such as robots, packaging machines, and automated production lines.
• Long lifespan, low maintenance: thanks to precisely hardened components that always operate under balanced loads, the cycloidal gearbox has a durable lifespan and requires little maintenance.
• High precision: stable speed control, without jerking or deviation, highly suitable for servo systems, industrial robots, and CNC machines.
• Diverse mounting types and reduction ratios: easily combinable with various types of electric motors and inverters, suitable for diverse spaces and technical requirements.

Applications of Cycloidal Gearboxes

Cycloidal Gearboxes (BWD, XWD, XWED, XLED…) are widely used in various industrial fields due to their stable transmission, high load capacity, and precision. Some common applications include:

• Heavy industrial machinery: such as presses, steel rolling mills, crushers, and heavy-duty conveyors - where high torque and stable operation are required.
• Automation systems and industrial robots: due to their high precision and low backlash, Cycloidal Gearboxes are highly suitable for pick-and-place robots, welding robots, or precise servo control devices.
• Packaging, pharmaceutical, and food industries: used in filling machines, packaging machines, mixers, labeling machines, etc., with the advantages of smooth, stable operation and easy cleaning.
• Environmental and wastewater treatment industries: installed in agitators, aerators, and sludge presses, providing powerful force transmission and energy savings.
• Lifting equipment, conveyors, and cargo lifts: Cycloidal Gearboxes help ensure smooth, safe, and continuous load handling over long periods.
• Agricultural and woodworking machinery: used in grinders, crushers, feed mixers, and automatic feeding systems.
