16、sel (compression-ignition) engines.The specified shaft ends and hubs may be used with or without Woodruff keys.NOTE The specified shaft ends and hubs can also be used for other applications where no specific standards exist.2 Dimensions and tolerances2.1 GeneralTo ensure satisfactory operation of th

17、e taper drive, it is necessary for manufacturers to provide such cone angle tolerances that the contact between the male and female cones commences at the major diameter.2.2 Shaft ends with taperShaft ends shall be as shown in Figure 1 and Table 1 or Figure 2 and Table 2. The shaft ends taper and th

18、read (Figure 1) may be made optionally according to type 1 or 2. However, it shall be possible to screw the go-gauge for the thread up to the XX line for both these types.Type 3 is a configuration with the thread inside of the taper. This configuration saves space and avoids the critical interface b

19、etween the taper and the thread of the configuration type 1 or 2.2.3 Keyways of hub with taperHub keyways shall be as shown in Figure 3 and Table 3. The length of the hub cone shall be such that, after assembling, the face at the smaller diameter of the hub cone lies so far in front of the XX line (

20、see Figure 1 and Figure 2) that the fixing nut can be correctly screwed up.Dimensions in millimetresa) Type 1 ISO 2015 All rights reserved 1BS ISO 6519:2015ISO 6519:2015(E)b) Type 2Figure 1 Shaft ends type 1 and type 2Table 1 Shaft ends type 1 and type 2Dimensions in millimetresdanom.d1l1max.l20-1t1
