Foreword

This standard is GB/T 14786-1993 "Tractors and agricultural and forestry machinery wheel torsional fatigue test method" amendment. In addition to the revision The editorial changes, the standard compared with GB/T 14786-1993, the main changes as follows. --- Change the standard name; --- Added Chapter 2 normative references. This standard from the date of implementation instead of GB/T 14786-1993. This standard is proposed by the China Machinery Industry Federation. This standard by the National Standardization Technical Committee tractor centralized. This standard was drafted. Luoyang Tractor Institute, the National Tractor Quality Supervision and Inspection Center. The main drafters of this standard. Zhang Xiao Yuan, Wang Hongbin. This standard replaces the standards previously issued as follows. --- GB/T 14786-1993. Agriculture and forestry tractors and machinery Driving wheel torsion fatigue test method

1 Scope

This standard specifies the agricultural and forestry tractor and mechanical drive wheel torsion fatigue test method. This standard applies to tractors, combine harvester and agricultural machinery equipped with driving wheels of the tire.

2 Normative references

The following documents contain provisions which, through reference in this standard and become the standard terms. All dated references, which are subsequently owned Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to reach an agreement based on this standard research Whether you can use the latest versions of these files. For undated references, the latest version applies to this standard. Agricultural tire series

3 test sample

The test sample should be the finished product wheel passed the factory inspection.

4 test equipment

4.1 The test bed should have a device that will allow the wheel to withstand alternating clockwise and counterclockwise torque (see Figure 1). Other loading principles The same test bench can also be used. 1 --- test bench power input; 2 --- test bed wheel; 3 --- connecting flange; 4 --- Platen, briquetting; 5 --- test wheels; 6 --- hinge seat; 7 --- disc 8 --- test bench power output.
