Description of Nomenclature
For technical clarification, you will find below the individual descriptions relating to rotary table element s referred to in this catalogue.
Clamping Torque
The clamping torque means the efficacy of the clamping mechanism, the clamping force of the worm gear is excluded.
The clamping torque shown on this catalogue is measured at 5(3.5) MPa hydraulic pressure and 0.55~0.7 MPa air pressure.
Allowable Worm Wheel Torque
This allowable worm wheel torque is equal to the allowable torque for the worm wheel when the table rotation speeds is 1 min-1.
Which is subject to the standard stipulated by the Japan Gear Manufacturers Association.
Update Accuracy Identification
Accuracy of Positioning by ISO 230-2 Standard (Unidirectional systematic positioning deviation of an axis)
The inspection presentation of ISO 230-2 is based on continuously 5 revolutions of repeatedly clockwise and counter-clockwise test, to diagnose unidirectional systematic positioning deviation.
Remark: Due to environmental influences during the measurement, the recorded measuring error may exceed the catalog limit value by up to 10%.
Accuracy of Repeatability by ISO 230-2 Standard (Unidirectional repeatability of positioning)
The inspection presentation of ISO 230-2 based on continuously 5 revolutions of repeatedly clockwise and counter-clockwise test, to diagnose nidirectional systematic repeatability of positioning deviation.
Remark: Due to environmental influences during the measurement, the recorded measuring error may exceed the catalog limit value by up to 10%.
Measurement Standards of Positioning Accuracy and Repeatability are Different
