21、ope and field of application This International Standard specifies the dimensions for interchangeability of propeller bosses and propeller shaft ends in the shaft diameter range of20 to160mm with a taper of1:10 1) , intended for installation on inboard-engined pleasure craft. 2 References ISO/R773,

22、Rectangular or square parallel keys and their corresponding keyways (Dimensions in millimetres).

23、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 the conical portion of the shaft end designed to transmit the full propeller shaft torque to the propeller, while allowing for disassembly 4

24、Dimensions The dimensions shall be those shown in the Figure and Table. The “reference dimensions” indicated in the Table shall be considered nominal dimensions for guidance only. Configurations shown in the Figure not specified by dimensions in the Table are not essential to interchangeability and

25、are therefore left to the discretion of the manufacturer. Nominal diameters without brackets shall be preferred; 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 the

26、Figure 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 corner 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 individu

27、al methods to comply with the configuration of the coupling and/or particular needs. Length of the thread G shall be equal to thread diameter T. The part of the thread engaged by the propeller nut shall be not less than80% of the thread length G. 6 Tolerances 6.1 Shaft end taper small diameter, A Th

28、e tolerances shall be as given in the Table. The tolerance deviations are calculated from the nominal diameter. 6.2 Boss taper large diameter, B The tolerances shall be as given in the Table. 6.3 Cone angle The tolerances shall be cone diameter tolerances as in ISO1947 with tolerance ranges equal to

29、 the diameter tolerance ranges specified in6.1 and6.2 for diameters A and B respectively. 6.4 Key and keyway The tolerances shall be those given for normal keys in ISO/R773. 6.5 Boss length, L The tolerance shall be 0,5mm. 7 Threads Threads shall be M fine. 8 Designation Both shafts and propeller bo

30、sses constructed in accordance with these requirements shall be designated by a reference to this International Standard, and the nominal diameter.
