The LSD series small harmonic drive is a newly developed strain wave gear/drive series based on the LSS series to fulfil the needs of the market. This type of mini harmonic drive only uses a uni-body type wave generator. Compared with the LSS series, the LSD strain wave gearbox is more compact and thin-walled. The size of gearbox LSD is much smaller.
As a professional strain wave reducer manufacturer, Laifual Drive provides strain wave gearboxes that can be widely applied in various scenarios.
Applications of LSD Strain Wave Gearing:
Industrial robots;
Service robots;
Metal machine tools;
Printed circuit manufacturing equipment;
Wood, light metal, plastic machine tools.
