16、injection pumps and common-rail high pressure pumps for diesel (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 a
17、nd tolerances 2.1 General To ensure satisfactory operation of the 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 taper Shaft ends shall be as shown in Figure
18、1 and Table 1 or Figure 2 and Table 2. The shaft ends taper and thread (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.
19、 This configuration saves space and avoids the critical interface between the taper and the thread of the configuration type 1 or 2. 2.3 Keyways of hub with taper Hub 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 s
20、maller diameter of the hub cone lies so far in front of the XX line (see Figure 1 and Figure 2) that the fixing nut can be correctly screwed up.
