Strain Wave Gears

LHS(G) (High-torque) Standard Hat-type Strain Wave Gear

Ref: LHS

The flexspline of the LHS standard hat-type flexspline strain wave gear has a at flanged barrel structure. A traditional key connection and cross slider coupling can be used to connect with the motor, and the wave generator can be configured for a large diameter through-hole or a solid input shaft structure. A support bearing and a fully sealed structure can be designed for the strain wave gear, making it useful for threading components through and attaching a bevel gear or timing belt transmission at the input end.

The LHS standard hat-type flexspline strain wave gear suits large hollow structures, efficiently solving internal power line problems. Telecom lines, air pipelines, and other intricate built-in drive device designs can be improved by integrating compact hat-type flexspline strain wave gears. It also has the characteristics of high cost-effectiveness, easy installation, high efficiency, low backlash, high positioning accuracy, and high rotation accuracy.

Leaderdrive hat-type harmonic drive system solutions are developed based on cutting-edge research by our R & D department. We can suit gears and component sets to specific applications based on user needs. Contact us to learn more about this service.

Ref: LHSG

The LHSG high-torque hat-type flexspline strain wave gear uses high-rigidity bearings and an overall strengthened design to increase the torque carrying capacity by more than 30% compared to the LHS harmonic speed reducer standard series. In addition to reducing the weight of machinery and equipment, the decrease in the weight of industrial robots can increase the robot's speed and payload weight.

Since its founding in 2003, Leaderdrive has been researching and developing innovative harmonic drive systems. Each gear or component set we produce demonstrates the latest developments in high-precision cost-efficient strain wave gearing. Contact us to discuss how our high-torque hat-type strain wave gears can upgrade your mechanical systems.

Parameters

Applications:

The LHS standard hat-type flexspline strain wave gear can be widely used in robots, humanoid robots, metal processing machinery, semiconductor manufacturing equipment, laser equipment, printed circuit manufacturing equipment, measurement and analysis test equipment, medical equipment, telescopes, optical testing equipment, metal machine tools, photovoltaic equipment, packaging equipment, aerospace, and other fields.

The LHSG high-torque hat-type flexspline strain wave gear can be widely used in: robots, humanoid robots, metal processing machinery, semiconductor manufacturing equipment, laser equipment, printed circuit manufacturing equipment, telescopes, metal machine tools, photovoltaic equipment, and other fields.

Models:

The LHS standard hat-type flexspline strain wave gear series is divided into six models according to the connection form of the input end and the wave generator cam and other aspects:

LHS-I model: The input shaft is directly matched with the wave generator's inner hole and connected by a flat key. It can be used to connect the circular spline input and flexspline end output and vice versa.

LHS-II series: The input shaft is connected to the wave generator's inner hole through a cross slider coupling. It can be used to connect the circular spline input and flexspline end output and vice versa.

LHS-III series: There is a large-diameter hollow shaft hole in the middle of the wave generator cam, and a support bearing is designed inside the strain wave gear. It is very suitable for threading. The fully sealed structure is easy to install.

LHS-III-ST model: Based on the LHS-III strain wave gear, the original fully enclosed structure is simplified to a semi-enclosed structure, allowing users to have greater design freedom.

LHS-CL-III model: It is a lightweight version of the LHS-III. Through the optimization of structure and materials, the original performance parameters remain unchanged. The weight of the harmonic reducer itself is reduced to withstand faster speeds and larger loads after being used on industrial robots.

LHS-IV model: The wave generator cam comes with an input shaft, and the strain wave gear is designed with a supporting bearing inside and a fully sealed structure. It is very suitable for occasions where bevel gears or timing belt transmissions need to be installed at the input end.
