Foreword

GB/T 4459 "Mechanical Drawing" is divided into the following eight sections.

--- GB/T 4459.1-1995 Mechanical drawing thread and threaded fastener representation;

--- GB/T 4459.2-2003 mechanical drawing gear representation;

--- GB/T 4459.3-2000 mechanical drawing spline representation;

--- GB/T 4459.4-2003 mechanical drawing spring representation;

--- GB/T 4459.5-1999 mechanical drawing center hole representation;

This section GB/T 4459 Part 7.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This Part replaces GB/T 4459.7-1998 "Mechanical Drawing Rolling Representation", compared with GB/T 4459.7-1998, the main

Technical changes are as follows.

--- Increasing the normative references;

--- In accordance with ISO 8826-2.1994 "Technical drawings of rolling bearings Part 2. Detailed and simplified representation" in Table 1 to correct

"Element symbol" choice note, an increase of footnote b;

--- In order to make the three kinds of painting (generalized, characteristic and prescriptive painting) as a separate side by side, the original "5 simplified painting method" in this chapter

There are two chapters, "General Picture" (formerly 5.1) and "Special Picture" (formerly 5.2)

Painting method ", and subsequently adjust the relevant chapter number;

--- A number of words and illustrations made the necessary changes, the text is modified as shown in Table 1, Table 2 will be "adjustable" standard "self-aligning", "not

Adjustable heart "norms" non-self-aligning ", the legend modified in Table 3, the figure 3.6;

--- The original "Appendix B (hint of appendix)" to "Appendix A (normative)";

--- The original "Appendix A (informative) reference document" to "references."

This section is based on ISO 8826-1.1989 "Technical drawings rolling bearings Part 1. General and simplified notation" and

ISO 8826-2.1994 "Technical drawings rolling bearings Part 2. Carefully simplified notation" integrated preparation, with two international standards

The degree of consistency is not equivalent.
