22 de mar. de 2024 · The main document for ISO Metric Threads: * List and definition of symbols. * Tolerance classes definition. * Designation rules. * Allowance Chart – Per class and pitch. * Normal Length of Engagement Chart – Per diameter and pitch. * Tolerance fields Charts – Per diameter and pitch. * Root radius Charts and formulas.
The most commonly used tolerancing system for shafts and holes is detailed in ISO 286-1 & 286-2. The first provides the charts for the fundamental deviations (G, j, etc.) and tolerance grades (7, 8, 9, etc.), out of which the limits of the tolerance classes (H7, g6, etc.) can be calculated.
This will vary from one brand to another for motors of the same HP, speed or enclosure. NEMA C face motors with a rigid base have different BA dimensions in the following instances: 143TC & 145TC – 2 3/4” instead of 2 1/4”. 182TC & 184TC – 3 1/2” instead of 2 3/4”. 213TC & 215TC – 4 1/4” instead of 3 1/2”. 254TC & 256TC – 4 ...
