Gear Racks, Steel, Tempered, Helical Tooth, Module 2
Material: High-quality, specially treated bright steel with approx.
900 N/mm² tensile strength. Helical tooth system, right hand 19° 31' 42''. Milled teeth, tooth quality 8e27. For continuous linking. See also the matching left hand-toothed counterparts to simplify the mounting.
Note: These right-handed racks are designed to be used in combination with our helical-toothed left-handed gears.
1) GTf /300 = total pitch error, i.e. the max. permissible deviation (per 300 mm) of the measured length of the rack compared to the theoretical length L300, with L300 = (m / cos ß)
* p * z300).
*Tangential force at tooth, calculated for z = 20. With a smaller number of teeth, the tangential force has to be reduced by 10%.
