DIN 58400/ 58405/ 58412 are withdrawn, there is no ISO standard for gears with module below 1 mm
(iso 1328-2 defines total radial composite tolerance for module from 0,2 up to 10, but runout is...
Maybe someone knows gear drives (or speed reducers, or gearboxes) such as Nabtesco, Sumitomo . All their output parameters are similar, i mean torque rating, accelerating torque/ decelerating torque 250%, peak torque 500% and rating life about 6000 hours. Who knows standards (international or...
thank u mfgenggear, but it is kind of obviously:)
what i meant before is that i can't find information about how to calculate upper and lower deviation for span measurement.
ISO 21771 describes how to calculate it, but there are some stupid things:
for example 2 formulas from page 67 (BS ISO...
Please, help me:)
I'm from Russia and everybody here is working according to GOST standard, but right now i need to build a spur gear according to ISO 1328 and i've got one problem: i can't find information about span deviation, i mean minimum and maximum. For example in GearTrax (gear...
