17、995 BSI 11-1999 2 Foreword The text of the International Standard from ISO/TC188, Small craft, of the International Organization for Standardization (ISO) has been taken over as a European Standard by CEN/CS. This European Standard supersedes EN24566:1989. This European Standard shall be given the s
18、tatus of a national standard, either by publication of an identical text or by endorsement, at the latest by October1995, and conflicting national standards shall be withdrawn at the latest by October1995. According to the CEN/CENELEC Internal Regulations, the following countries are bound to implem
19、ent this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, United Kingdom.ENISO4566:1995 BSI 11-1999 3 1 Scope This International Standard specifies the dimensions for interc
20、hangeability of propeller bosses (hubs) and propeller shaft ends in the shaft diameter range of20mm to160mm with a taper of1:10 1) , intended for installation on inboard-engined small craft. 2 Normative references The following standards contain provisions which, through reference in this text, cons
21、titute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of
22、 the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO/R773:1969, Rectangular or square parallel keys and their corresponding keyways (Dimensions in millimetres). ISO1947:1973, System of cone tolerances for conical workpieces from C=
23、1:3 to1:500 and lengths from6 to630mm. 3 Definitions For the purposes of this International Standard, the following definitions apply. 3.1 nominal diameter diameter of the large end of the shaft end taper, which is the same as the diameter of the cylindrical shaft, ignoring tolerances 3.2 taper coni
24、cal portion of the shaft end designed to accommodate a key to transmit the full propeller shaft torque to the propeller, while allowing for disassembly 4 Dimensions The dimensions shall be those shown in Figure 1 and Table 1. The “reference dimensions” indicated in the table shall be considered nomi
25、nal dimensions for guidance only. Configurations shown in Figure 1 not specified by dimensions in Table 1 are not essential to interchangeability and are therefore left to the discretion of the manufacturer. Nominal diameters without brackets shall be preferred; those in brackets are a second choice
26、. Thread diameters without brackets shall similarly be preferred; those in brackets are alternatives. 5 Construction details Details indicated in Figure 1 are not intended to restrict design; nor are they to scale. Types and methods of construction or machining of the key, the keyway and their corne
27、r radii, the thread undercut and the thread end, or of other optional details (i.e.safety pin hole, centring point, etc.) are left open for individual methods to comply with the configuration of the coupling and/or particular needs. The length of the thread l 2shall be equal to thread diameter d 2 .
28、 The part of the thread engaged by the propeller nut shall be not less than80% of the thread length l 2 . 6 Tolerances 6.1 Shaft end taper small diameter, d 1 The tolerances shall be as given in Table 1. The tolerance deviations are calculated from the nominal diameter. 6.2 Boss taper large diameter
29、, D The tolerances shall be as given in Table 1. 6.3 Cone angle The tolerances shall be cone diameter tolerances as in ISO1947 with tolerance ranges equal to the diameter tolerance ranges specified in6.1 and6.2 for diameters d 1and D respectively. 6.4 Keyways and keys The tolerances shall be those g
30、iven for normal keys in ISO/R773. 6.5 Boss length, l 1 The tolerance shall be 0,5mm. 7 Threads Propeller nuts and shaft ends shall use M-Fine threads. 8 Designation Both propeller shafts and bosses constructed in accordance with these requirements shall be designated by a reference to this Internati
31、onal Standard, and the nominal diameter.
