🛠️ Technical Deep Dive

Harmonic Reducers: These components are typically composed of a wave generator, a flexible gear (flex spline), a flexible bearing, and a rigid gear (circular spline). They are known for their high transmission ratios, compact size, light weight, and high efficiency, making them suitable for robotics. The wave generator induces elastic deformation in the flex spline, causing its teeth to progressively mesh with the rigid gear to transmit motion and power.
Planetary Reducers: These reducers utilize a system of gears, including a central sun gear, multiple planet gears revolving around it, and an outer ring gear. This configuration provides advantages such as high torque transmission, compact dimensions, high efficiency, and smooth operation.
Joint Modules: Wanliyang's joint modules are designed as highly integrated power systems, combining elements like frameless torque motors and reducers (harmonic or planetary). These modules prioritize high torque density (maximum power for minimum weight), precision, efficiency, and fluid motion. Frameless motors, consisting only of a stator and rotor, allow for optimal integration into the joint structure to minimize size and weight.
Manufacturing Capabilities: Wanliyang leverages its extensive experience in gear process design and precision manufacturing from the automotive industry. The company operates two CNAS-accredited laboratories and possesses comprehensive equipment for product testing and trial production.
