Foreword
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1.Structure and drafting rules for standardization documents"
Drafting.
This document replaces GB/T 5844-2002 "Tire Coupling". Compared with GB/T 5844-2002, except for structural adjustment and editorial
In addition to the modifications, the main technical changes are as follows.
a) The marking method of the coupling has been changed (see 4.2, 3.4 of the.2002 edition);
b) The coupling J1 type shaft hole has been deleted (see Table 1 of the.2002 edition);
c) The outer diameter of the coupling sleeve is increased (see Figure 1 and Table 1);
d) Added the relevant parameters of the coupling connection bolt hole (see Table 1);
e) The structural steel material grades have been changed (see Table 3, Table 3 of the.2002 edition);
f) The 4.8-grade connecting bolts of the coupling have been deleted (see Table 3 of the.2002 edition);
g) Added tightening requirements for coupling bolts (see 7.6);
h) Added the coupling assembly accuracy requirements (see 7.7);
i) Deleted the requirements for semi-finished rubber products (see Table 4 of the.2002 edition);
j) Added the requirements for rubber physical properties test specimen types (see Table 6);
k) The hot air aging test method standard for vulcanized rubber has been changed (see Table 6, Table 4 of the.2002 edition);
l) Added torque test method (see 8.2).
