Overview Honpine provides customized harmonic drive reducer solutions for robot joint module manufacturers. Solutions are offered as OEM or customer-specific designs to simplify assembly, improve mechanical and electrical integration, and accelerate product development for joint actuators.

Customization services

• Shaft machining and shaft geometry adaptations (length, diameter, keyways)
• Flange modifications and integrated flange designs for specific mounting interfaces
• Housing and cover optimization to match installation envelopes and reduce weight
• Mechanical interface adaptations to customer mounting and assembly processes

Common customization options and adaptations

• Waterproof variants: splash and spray protection, splash‑submersible designs up to approximately 1 m depth (according to specification)
• Low-temperature adaptations for cold‑environment operation
• Hollow bore and large through‑hole options for lead screw, cable or shaft pass‑through
• Integrated connectors, cable routing and preassembled harnesses for faster installation
• Support for mating with motors, encoders, brakes and integrated drive units

Benefits

• Simplifies assembly and reduces integration effort for robot joint modules
• Accelerates development with OEM/custom modifications tailored to application needs
• Enables more compact, lighter and better‑integrated actuator assemblies

Applications

• Robot joint actuators and compact joint modules
• Collaborative robots (cobots) and humanoid robot joints
• Precision rotary actuators, turntables and integrated robotic assemblies requiring custom mechanical interfaces

Technical specifications

• Product type: Customized harmonic drive reducer for robot joint actuator applications
• Services offered: OEM/custom design including shaft machining, flange and housing modification, mechanical interface adaptation
• Typical compatibility: designed to integrate with frameless torque motors, encoders (singleturn/multiturn), brakes and drive units
• Environmental options: waterproofing (splash, spray, shallow immersion up to ~1 m) and low‑temperature adaptations
• Typical voltage range (for integrated motor modules): DC24V–DC48V
• Example torque ranges by family: approximately 4 N·m to 1200 N·m (dependent on series and customization)
• Encoder options: singleturn (e.g. 17‑bit or 23‑bit) and multiturn (e.g. 16‑bit); dual‑encoder configurations possible
• Hollow bore and large‑diameter passage configurable per customer requirements
