Overview
The Harmonic Drive 65-100-533106 circular spline is a precision gear component designed for integration into SHD and SXD series strain wave gearbox assemblies. The Harmonic Drive 65-100-533106 circular spline is a rigid ring with internal teeth that forms the core element of Harmonic Drive’s zero-backlash gearing technology. This component engages with the flexspline across the major axis of the wave generator to transmit high-precision, high-torque motion with minimal wear and exceptional repeatability.
Key Features
- Precision internal tooth design for zero-backlash engagement with flexspline
- Rigid steel construction for consistent torque transmission and load capacity
- Serialized and matched factory components for optimal assembly performance
- Compatible with standard Harmonic Drive lubrication (grease or oil) as specified
- Designed for high-speed input and reduced-speed output configurations
- Compact, lightweight geometry for space-constrained installations
Technical Specifications
Verify dimensional and load specifications with Harmonic Drive technical documentation or your system integrator before final assembly. Component specifications vary by gearbox ratio and configuration.
Typical Applications
- Robotic joint actuators and articulated arms
- Precision positioning systems and motion control
- Industrial automation machinery requiring backlash-free operation
- Aerospace and medical device motion control systems
- Satellite and space actuator mechanisms
- CNC spindle drives and precision tool positioning
