Compound Micro Gears
Dual-stage and multi-section micro gears for compact transmission systems
MH manufactures custom compound micro gears, dual-stage micro gears, and multi-section small-module gear components based on customer drawings and technical requirements. These gears are used in compact gearboxes where multiple transmission stages must be integrated into limited space.
Compound micro gears are more complex than single spur gears. Two or more gear sections must maintain accurate relative position, concentricity, and runout after machining and heat treatment. For compact robot actuators, miniature gearboxes, and precision mechanisms, this directly affects backlash, transmission smoothness, and assembly reliability.

Manufacturing Challenges
Compound micro gears often combine two gear stages, different tooth counts, hub features, holes, shoulders, and thin sections in one component. The process must control both gear geometry and mechanical reference surfaces.
MH focuses on:
- Alignment between gear sections
- Concentricity and runout control
- Tooth profile accuracy after heat treatment
- Burr control between closely spaced gear sections
- Fixture and clamping strategy
- Inspection planning for multiple functional features
- Batch consistency for gearbox assembly
Typical Applications
- Compact robot actuator gearboxes
- Humanoid robot hand transmissions
- Small electric drive systems
- Precision instruments
- Medical device mechanisms
- Aerospace miniature motion assemblies
