Harmonic Drive is a trademark of Harmonic Drive LLC.
1. Recommended bolt : JIS B 1176 socket head cap screw strength range : JIS B 1051 over 12.92. Torque coefficient : K=0.23. Clamp coefficient A=1.44. Coefficient of friction: 0.155. Strict compliance to the recommended screw tightening torques is especially important for the lightweight aluminum housing flange. Exceeding the recommended values (over tightening) can cause deformation of the housing flange under the bolt heads. This will result in the housing slipping under full torque loads. (Please contact a Sales Engineer for more information.)
Using new lightweight materials and an optimized design, a 30% reduction in weight has been achieved without reducing the torque rating of the gear unit or significant changes to the interface dimensions. This weight reduction, combined with the CSG's high torque ratings, results in an exceptional “Torque Density” making it ideally suited for many applications including…
Industrial Robots – allowing operation with higher acceleration rates and payload capacity
Mobile Robots – allowing lower weight designs which improves battery life without sacrificing performance

No-load running torque is the input torque (high speed shaft) which is required to rotate the Harmonic Drive™ gear with no load applied to the output.
Compensation Value for Each RatioThe no load running torque of Harmonic Drive gears varies with the gear ratio. The graphs indicate a value for ratio 100. For other gear ratios, add the compen-sation value from table 3-2.

Efficiency Compensation Coefficient
The gear efficiency is affected by many factors. Efficiency depends on the gear ratio, input speed, load torque, temperature, quantity of lubricant and type of lubricant.Efficiency values shown in the tables shown below are for rated torque. If the actual load torque is below rated torque, a compensation factor must be used.

Efficiency Compensation Coefficient
The gear efficiency is affected by many factors. Efficiency depends on the gear ratio, input speed, load torque, temperature, quantity of lubricant and type of lubricant.Efficiency values shown in the tables shown below are for rated torque. If the actual load torque is below rated torque, a compensation factor must be used.

No-load running torque is the input torque (high speed shaft) which is required to rotate the Harmonic Drive™ gear with no load applied to the output.
Compensation Value for Each RatioThe no load running torque of Harmonic Drive gears varies with the gear ratio. The graphs indicate a value for ratio 100. For other gear ratios, add the compen-sation value from table 3-2.

Harmonic Drive is a trademark of Harmonic Drive LLC.
1. Recommended bolt : JIS B 1176 socket head cap screw strength range : JIS B 1051 over 12.92. Torque coefficient : K=0.23. Clamp coefficient A=1.44. Coefficient of friction: 0.155. Strict compliance to the recommended screw tightening torques is especially important for the lightweight aluminum housing flange. Exceeding the recommended values (over tightening) can cause deformation of the housing flange under the bolt heads. This will result in the housing slipping under full torque loads. (Please contact a Sales Engineer for more information.)
Using new lightweight materials and an optimized design, a 30% reduction in weight has been achieved without reducing the torque rating of the gear unit or significant changes to the interface dimensions. This weight reduction, combined with the CSG's high torque ratings, results in an exceptional “Torque Density” making it ideally suited for many applications including…
Industrial Robots – allowing operation with higher acceleration rates and payload capacity
Mobile Robots – allowing lower weight designs which improves battery life without sacrificing performance
