2. Main Features Of  LSS Series Harmonic Drive
High Precision Gear 
Many teeth in the position of the two 180-degree symmetry Joggle.Gear tooth pitch error and the cumulative influence of pitch error on rotation accuracy is average. Very high position accuracy and running accuracy can be obtained.
High Ratio
Single harmonic drive gear ratio of up to i=30 to 500. Simple structure, three basic components on the shaft can be achieved with high reduction ratios.
High Load Capacity
Harmonic drive, tooth and meshing of the teeth is the contact, together with colleagues more meshing number of teeth, thus the load per unit area is small. Higher load capacity than other forms of transmission.
Small Volume and Light Weight
High Transmission Efficiency and Long Service Life
Stable Transmission and Low Noise

Spur gears are the most common type of gears. They have straight teeth, and are mounted on parallel shafts. Sometimes, many spur gears are used at once to create very large gear reductions.


Spur gears are the most easily visualized common gears that transmit motion between two parallel shafts. Since the tooth surfaces of the gears are parallel to the axes of the mounted shafts, there is no thrust force generated in the axial direction. Also, because of the ease of production, these gears can be made to a high degree of precision.

The unit to indicate the sizes of spur gears is commonly stated, as specified by ISO, to be "module". In recent years, it is usual to set the pressure angle to 20 degrees. In commercial machinery, it is most common to use a portion of an involute curve as the tooth profile.

A sprocket or sprocket-wheel is a profiled wheel with teeth, or cogs,that mesh with a chain, track or other perforated or indented material.The name 'sprocket' applies generally to any wheel upon which radial projections engage a chain passing over it. It is distinguished from a gear in that sprockets are never meshed together directly, and differs from a pulley in that sprockets have teeth and pulleys are smooth.
