Foreword

This standard is one of the "elastic ring" series of standards, the series includes. --- GB/T 893 hole with a flexible ring; --- GB/T 894 shaft with a flexible ring; --- GB/T 896 opening ring; --- GB/T 959.1 retaining ring technical conditions elastic ring. This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 893.1-1986 "hole with a ring type A" and GB/T 893.2-1986 "hole with a flexible ring B Type ", compared with GB/T 893.1-1986, GB/T 893.2-1986, the main technical changes are as follows. --- merge GB/T 893.1-1986 and GB/T 893.2-1986 as a standard and modify the standard name; - increase standard (type A) specifications. d1 = 210,220,230,240,250,260,270,280,290 and 300mm (see Table 1); --- modify the standard (A type) thickness (s) and other dimensions and tolerances (see Table 1); - specify the installation of the clamp hole (d5) for the minimum limit size (see Table 1, Table 2); --- increase the carrying capacity of the groove FN standard value (see Table 1, Table 2, Chapter 5); - increase the carrying capacity of the retaining ring FR standard value (see Table 1, Table 2, Chapter 5); --- increase the installation tool standards and specifications (see Table 1, Table 2); --- increase the heavy (B type) its d1 = 20mm ~ 100mm (see Table 2); - increase groove design and installation (see Chapter 6, Chapter 7); --- delete the original Appendix A. This standard is proposed by the China Machinery Industry Federation. This standard is nationalized by the National Standardization Technical Committee on Fasteners (SAC/TC85). This standard is responsible for the drafting unit. China Machine Productivity Promotion Center. This standard participates in the drafting unit. Anhui Ningguo Dongpo Fastener Co., Ltd., Shanghai Ball Ming Standard Parts Co., Ltd., Hangzhou forward tooth Wheel box group co., Ltd. This standard is interpreted by the National Standardization Technical Committee for Fasteners. This standard replaced the previous version of the standard release. --- GB/T 893-1976; --- GB/T 893.1-1986; --- GB/T 893.2-1986. Hole with a flexible ring

1 Scope

This standard specifies the standard type (type A) of the aperture d1 = 8mm ~ 300mm and the heavy type (type B) of d1 = 20mm ~ 100mm. Hole with a ring, given the design of the groove design data. This standard applies to the use of fixed parts or parts in the hole (such as rolling bearings) with an axial force can withstand the ring.
