Strain Wave Gears
LCS(G) (High-torque) Standard Cup-shaped Strain Wave Gear
Ref: LCS
Standard cup-shaped flexspline strain wave gears are composed of four parts: a flexspline, a rigid circular spline, a wave generator, and roller bearings. Generally, the circular spline end is fixed, and the flexspline end is the output connecting with the motor. They are used as harmonic speed reducers in many mechanisms that perform rapid, precision motions.
The LCS cup-shaped flexspline strain wave gear is highly efficient and cost-effective. The simple structure with high rigidity and low backlash means that it can withstand high torque and obtain excellent positioning accuracy and rotation accuracy.
Leaderdrive is an innovative R & D and manufacturing company specialized in the development of strain wave gears and other gearbox and gearhead solutions. Contact us for more information on these products, including specifications, data, and warranties.
Ref: LCSG
The LCSG high-torque cup-shaped flexspline strain wave gear is the high-torque version of the standard LCG model. It comprises high-rigidity roller bearings and an overall strengthened design. The torque carrying capacity is 30% higher than that of the LCS series.
The LCSG high-torque cup-shaped flexspline strain wave gear has high torque capacity, a simple structure, high rigidity, low backlash, and long life. While bearing high torque, it can increase the operating speed to save installation space and reduce overall costs.
Leaderdrive strives to continuously develop our product range, ensuring that our high-torque harmonic drive systems always meet industry needs. We welcome any inquiries about our technology and industry solutions from interested parties.

Models:
The LCS standard cup-shaped flexspline strain wave gear series is divided into two models according to the different connection forms of the input end and the wave generator cam:
LCS-I: The input shaft is directly matched with the wave generator's inner hole and connected by a flat key.
LCS-II: The input shaft is connected to the wave generator's inner hole through an Oldham coupling.
