Scope

GB/T 26660-2011 is the English-translated version of SWC大型整体叉头十字轴式万向联轴器.

GB/T 26660-2011 specifies the types, the basic parameters and dimensions, the technical requirements, the inspection rules and the signs, packaging and storage of the SWC large whole fork cross shaft universal coupling, which the text thereafter calls the large universal coupling.

Clause 1 applies it to large universal couplings that join two shafts whose axes differ, with a turning diameter of 620 mm to 1320 mm, a transmitted nominal torque of 1220 kN.m to 16000 kN.m and an axis angle of 5° to 15°.

The table of contents gives six clauses, printed as Scope, Normative references, Types, basic parameters and dimensions, Technical Requirements, Inspection Rules and logo, packaging, storage, followed by Appendix A, declared informative, which describes the selection of the universal coupling.

Clause 3 begins by dividing the large universal coupling into three types set out in Table 1, and gives the model designation as the letters SWC for the overall fork cross shaft universal coupling followed by the turning diameter in millimetres and the type code taken from Table 1; the draft breaks off inside that designation rule, so the three type names themselves, the dimension tables and the technical requirements are not shown.

Clause 2 cites GB/T 191, GB/T 1184, GB/T 1800.2, GB/T 3098.1, GB/T 3098.2, GB/T 4879, GB/T 6388, GB/T 11345, GB/T 13384, GB/T 19418 and JB/T 5000.14.

The foreword states that the standard was drafted according to the rules given in GB/T 1.1-2009, that it is handled by the National Standardization Technical Committee of machine shafts and accessories (SAC/TC109) and that the drafting units include China's second Heavy Machinery Group and Anhui Theil Heavy Industries Co., Ltd., alongside others the draft names only in garbled form.

The page estimates the full text at about 21,228 words. It was issued on 2011-06-16 and has applied since 2012-03-01.
