The strain wave gear, also known as the "harmonic drive", is a gearing component that is compact, light, and produces no backlash. It is an indispensable component for the reliable and accurate operation of light industrial robots and manipulators, especially as a speed reducer. MONTON is a leading manufacturer of strain wave gears; we have a strong R & D department, and we produce tailored harmonic drive systems for industry and academic partners.

Characteristics of MONTON strain wave gears:
High precision: As multiple teeth engage simultaneously at two 180° symmetric positions, the errors of the pitch of gear teeth and cumulative errors of the pitch of teeth have an average influence on rotation precision, contributing to very high position precision and rotation precision. 

Large drive ratio: The single-stage harmonious drive device has a simple structure with a drive ratio from 30:1 to 500:1. Therefore, three basic components on a single axis can realize a high drive ratio. 

High load capacity: In strain wave gear systems, the engagement between teeth is a kind of surface contact. As many teeth engage with each other at the same time, the load of each unit is small, which means the load capacity is higher than other drive forms. 

Compact and lightweight: Its volume and weight are reduced significantly compared with normal gear devices, and therefore the size is small, and the weight is light.
