This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsem
17、ent, at the latest by October 1995, and conflicting national standards shall be withdrawn at the latest by October 1995. According to the CENKENELEC Internal Regulations, the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greec

19、d specifies the dimensions for interchangeability of propeller bosses (hubs) and propeller shaft ends in the shaft diameter range of 20 mm to 160 mm with a taper of 1 :1 O”, intended for installation on inboard-engined small craft. 2 Normative references The following standards contain provisions wh
20、ich, through reference in this text, constitute provisions of this International Standard. At the time of publi- cation, 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 possibil
21、ity of applying the most re- cent editions of the standards indicated below. Members of IEC and IS0 maintain registers of cur- rent ly valid l nternat iona l Standards , ISO/R 773:1969, Rectangular or square parallel keys and their corresponding keyways (Dimensions in millime tres).

22、System of cone tolerances for conical workpieces from C = 1:3 to 1.500 and lengths from 6 to 630 mm. 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 di- am
23、eter of the cylindrical shaft, ignoring tolerances. 3.2 taper: Conical portion of the shaft end designed to accommodate a key to transmit the full propeller shaft torque to the propeller, while allowing for dis- assembly. 4 Dimensions The dimensions shall be those shown in figure1 and table 1. The “
24、reference dimensions” indicated in the table shall be considered nominal dimensions for guidance only. Configurations shown in figure 1 not specified by di- mensions in table 1 are not essential to interchange- ability and are therefore left to the discretion of the manufacturer. Nominal diameters w
25、ithout brackets shall be pre- ferred; those in brackets are a second choice. 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
26、methods of construction or machining of the key, the keyway and their corner radii, the thread undercut and the thread end, or of other optional details (.e. safety pin hole, centring point, etc.) are left open for individual meth- ods to comply with the configuration of the coupling and/or particul
27、ar needs. The length of the thread l2 shall be equal to thread diameter 4. The part of the thread engaged by the propeller nut shall be not less than 80 % of the thread length 12. 6 Tolerances 6.1 Shaft end taper small diameter, d, The tolerances shall be as given in table 1. The toler- ance deviati
28、ons are calculated from the nominal di- ameter. 1) IS0 8845 (to be published) will cover propeller shaft ends and bosses machined to a taper of 1 :I 6. 6.2 Boss taper large diameter, D The tolerances shall be as given in table 1 6.3 Cone angle The tolerances shall be cone diameter tolerances as in I
29、S0 1947 with tolerance ranges equal to the diam- eter tolerance ranges specified in 6.1 and 6.2 for di- ameters d, and D respectively. 6.4 Keyways and keys The tolerances shall be those given for normal keys in ISO/R 773. A-A 8 6.5 Boss length, Z, The tolerance shall be f 0,5 mm. 7 Threads Propeller
30、 nuts and shaft ends shall use M-Fine threads. 8 Designation Both propeller shafts and bosses constructed in ac cordance with these requirements shall be designated by a reference to this International Standard, and the nominal diameter.
