Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

With GB/T 6232- Compared with.1998, the main technical differences except for editorial changes are as follows. ---Modified the scope of the standard (see Chapter 1, Chapter 1 of the.1998 edition); --- Deleted the requirements for the position of the radius SR of the sphere of the nut seat centered on the sphere of the spoke nut seat (see Table 3 in the.1998 edition); ---The diameter of the bolt with the number of equal-spaced bolt holes centered on the cone of the spoke nut seat is 8 (see A.2, Table 2 of the.1998 edition). The translation method used in this standard is equivalent to ISO 5711.1995 "Agricultural and Forestry Tractor and Mechanical Wheel Mounting Dimensions on the Wheel Hub". This standard has made the following editorial changes. ---In order to be consistent with my country's drawing regulations, the letter "d" is replaced by the letter "D", and the letter "sr", "SRr" and "r" are replaced by the letter "SR"; ---In order to comply with the provisions of GB/T 1.1-2009, the content of "Note 3" in Appendix A of ISO 5711.1995 is changed to A.1.

1 Scope

This standard specifies the installation dimensions of agricultural and forestry tractors and machinery wheels on the hubs. Centering according to the spoke center hole is recommended as a new model Type. Note. Appendix A gives the installation dimensions of the wheel on the hub according to the spherical centering and conical centering of the spoke nut seat. The following installation dimensions do not mean that the wheels are interchangeable between the vehicle and the vehicle. This standard applies to agricultural and forestry tractors and mechanical spoke wheels, but does not apply to front and rear wheels equipped with gear reducers and corresponding mechanisms in the hub. Wheels assembled on the rear drive shaft.
