The importance of tooth shape design for harmonic reducer

During the movement of the harmonic reducer, keeping the flexspline and circular spline in contact without interfering is the prerequisite for ensuring that the harmonic reducer has excellent transmission performance. Therefore, the harmonic reducer has extremely high requirements in terms of angular transmission accuracy and stiffness. To achieve these high performance requirements, the tooth shape design is very important. Various reducer manufacturers in the industry have different understandings and designs. The ultimate goal is to increase the number of teeth in the tooth shape, so as to obtain higher transmission accuracy and rigidity.


Haozhi SP tooth profile advantage

The tooth shape of Haozhi harmonic reducer is based on the full research of IH tooth shape and curve mapping theory, and independently design and development of SP harmonic tooth shape and convex contour curve, and obtained the national invention patent. This toothed harmonic gear can simultaneously mesh up to 30% of the total number of teeth during operation, so that the harmonic reducer can improve the transmission accuracy and output torque performance by more than 30%, and the rigidity exceeds the industry's highest standard by more than 10% .
