Company Information
Traditionally, the design of a rigid gear sold on the market is based on the Conjugate Meshing Theory (Willis’s Theorem). However,
researchers at Leaderdrive have discovered that strain wave gearing meshing is more complex than that. Instead, strain wave gearing
meshing can be more accurately described by the Geometric Mapping Theory of Curves. By incorporating this theory into the design, this
patented technology has greatly improved the meshing of strain wave gearing, differentiating the product from competitors. The design can
also be further extended to high ratio rigid reducers for better precision and control.
A Unique Perspective on Harmonic Gearing
Tooth of Circular Spline Tooth of Flexspline
Leader's Tooth Design
Competitor's Tooth Design
1. Lower profile reduces bending stress at the base to improve torque capacity.
2. Wide tooth base and streamlined profile transition reduces core stress concentration.
3. Lower profile reduces displacement and strain in the flexspline, leading to longer flexspline life.
4. More than 20%-30% of tooth compare to other competitor in meshing contact to reduce surface contact pressure.

1.The assembly of a strain wave reducer must be carried out in a clean environment to avoid the introduction of any
foreign objects which may cause premature failure.
2.Be sure to have adequate lubrication on the tooth surface and flexible bearing. Avoid application design to have the
tooth face in constant upward position which could cause lubrication deficienc . If a constant upward gear face position
can not be avoided, fill grease cavity to fully submerge the meshing splines
3.When installing the cam, make sure the meshing is exactly at 6 o’clock and 12 o’clock as shown in picture 1. Should it
be off from the line of symmetry as shown in picture 2, the assembly will vibrate and fail
4.After assembly, trail run at a low speed of 100 rpm. Should any unusual vibration or noise is observed, stop and double
check the assembly. Contact a manufacturer representative immediately for assistance.
5.Only use the factory specified grease, do not use a substitute without factory approval
6.Only use grade 12.9 fasteners, and use thread loctite to prevent fasteners from loosening during operation.
7.The mounting surface must the flat within 0.01 mm and perpendicular to the axis within 0.01mm. The mounting threaded
holes or through holes must be within 0.1 mm of the theoretical location.

Grease Lubrication
All train wave reducer are lubricated by grease. Hollow shaft III series and solid shaft IV series are grease filled in the factory. There is no need
to add grease at installation. The other series internal chambers are grease filled. Need to add grease when installing wave generators.
Specially formulated for strain wave reducer application. It provides more excellent lubrication, higher efficiency at the harmonic
meshing, protects components from wear and extends component life.
Types of GreaseLD Super No. 096:
Specially formulated for small strain wave reducer application. It provides excellent lubrication when turning wave generation by
liquefying extreme pressure additive.
LD Super No. 098:
It has flow characteristic for longer service life, and also can be used in larger temperature range.

1. The seals at the input and output have to be carefully design. Dynamic seal should be a lip seal with structural support and the
stationary seal can be O-ring type or RTV. The sealing surface must have high surface finish and not defective.
2. Must use the factory recommended grease and not to mix with any other grease.
3. The grease application must be in accordance with the factory instructions.
4. If the strain wave reducer unit is operating in constant upright position, lubrication deficiency may occur, need to use extra grease.
5. The grease properties will vary with temperature. It degrades faster at high temperature. For optimum lubrication conditions, the
harmonic drive should operate below 70 degree C. The temperature rise should be less then 40 degree C.
6. The grease quality will have direct effect on the wear of the internal components. The recommended grease change interval is every
3000 operating hours.
