A cycloidal gearbox, also known as a cycloidal drive or reducer, is a mechanism for reducing the speed of an input shaft by a certain ratio while increasing torque. It utilizes a unique principle based on eccentric motion and cycloidal disc engagement to achieve high precision, exceptional shock load capacity, and remarkable efficiency in a compact design. These gearboxes are widely used in robotics, industrial automation, aerospace, and heavy machinery due to their durability and performance advantages over traditional gear systems.

Here are some frequently asked questions about cycloidal gearboxes to help you understand their functionality and benefits.
What makes a cycloidal gearbox different from a planetary gearbox?
A cycloidal gearbox uses an eccentric motion and cycloidal discs to achieve reduction, offering higher shock load capacity, zero backlash, and compact size. In contrast, a planetary gearbox relies on multiple gears meshing together, which can have more backlash and lower overload tolerance but might be more efficient in some high-speed applications.
How do I select the right cycloidal gearbox for my application?
Consider factors such as required reduction ratio, input speed, output torque, operating environment (temperature, humidity), mounting style, and space constraints. Review the product specifications table and consult with our engineering team for custom needs to ensure optimal performance.
What maintenance is required for a cycloidal gearbox?
Cycloidal gearboxes are low-maintenance. Regularly check for lubrication (typically every 10,000 hours of operation for standard models), inspect seals for wear, and ensure proper alignment. Avoid overloading beyond specified limits to prolong lifespan.
Can cycloidal gearboxes handle high shock loads?
Yes, one of the key advantages is their ability to withstand high shock loads and overload conditions without failure. The design distributes stress evenly across multiple lobes on the cycloidal disc, making them ideal for applications with sudden torque spikes.
Are custom ratios and sizes available?
Absolutely. We offer custom engineering services to tailor reduction ratios, shaft configurations, housing materials, and other parameters to meet specific application requirements. Contact our support team with your details for a quote.
What is the typical lifespan of a cycloidal gearbox?
With proper maintenance and within specified operating conditions, our cycloidal gearboxes can last over 20,000 hours. Lifespan depends on factors like load, speed, environment, and maintenance practices.
How does temperature affect performance?
Extreme temperatures can impact lubrication viscosity and material expansion. Our standard models operate between -20°C and 100°C. For environments outside this range, special lubricants and materials can be used to maintain performance.
Is backlash adjustable in cycloidal gearboxes?
Cycloidal gearboxes are designed to have inherently near-zero backlash due to their construction. It is not adjustable like in some other gear systems, but this fixed low backlash ensures consistent precision over time without need for readjustment.
