12、ne of a series of metric standards for elements of driving and driven machines. Others in the series include shaft centre heights (metric units) and metric keys and keyways, based on corresponding Recommendations of the International Organization for Standardization (ISO) and metric shaft fitment bo
13、res for cylindrical shaft ends.This specification is based on ISO Recommendation7751), and within the text, attention is drawn to the fact that the stated relationship between the length of long and short shafts is not maintained throughout the series. If subsequent revisions are made to the ISO Rec
14、ommendation in this or any other respect, this British Standard will be reconsidered.The tables for conical shaft ends include essential dimensions of keys and keyways because the key size is smaller than would normally be envisaged for a particular diameter of shaft. Tolerances for cones have not b

An appendix is also included giving values for transmissible torques for shafts, but it is emphasized that the table is given for guidance only (it forms part of the ISO Recommendation) and should not be directly used for design.A B

20、s will be the subject of a future standard.2 Relation between formsThe relation between the various forms of shaft ends, cylindrical and conical, is shown in Figure 1.
