Strain Wave Gears
LHD Ultra-Flat Hollow-Shaft Flexspline Strain Wave Gear
Ref: LHD
The flexspline of the LHD ultra-flat hollow-shaft flexspline strain wave gear has an ultra-thin hollow flanged shape. The design of the whole component set has been developed to reach the limits of flatness while maintaining harmonic speed reduction effectivity. The LHD is perfect for use in tight spaces such as power line connections, and it is very suitable for application in any scenario where the gear has thickness and bearing requirements. The hollow shaft can be used for threading wiring through the gear.
The LHD ultra-flat hollow-shaft flexspline strain wave gear has an ultra-flat structure, thin profile, and low weight. In operation, it maintains high rigidity, ultra-low backlash, and a substantial load-bearing capacity.
Leaderdrive supplies stain wave gears to industrial enterprises and research institutes around the world. If you would like to know more about our ultra-flat hollow-shaft models, please contact our technical team.

Product details
Parameters
Applications:
The LHD ultra-flat hollow-shaft flex spline strain wave gear can be widely used in robots, humanoid robots, printed circuit manufacturing equipment, metal machine tools, and other fields.
Models:
The LHD ultra-flat hollow-shaft flex spline strain wave gear series is divided into two models according to the different connection form of the input end and the wave generator cam:
LHD-I: The input shaft is directly matched and connected with the inner hole of the wave generator.
LHD-III: There is a large-diameter hollow shaft hole in the middle of the wave generator cam. The gear is designed with a supporting bearing inside, and the fully sealed structure is easy to install.
