This standard specifies the basic parameters, installation requirements and inspection methods of a single-type toothed chain (hereinafter referred to as slightly loose toothed chain). This standard is used for the start-stop of the vehicle, the reverse or recording of the poem. 2 Normative references

3.1 structure type, basic season number and size
for the shape of the wrong for the external user standard method, the shuttle is due to the pin type, and the sprocket is in step with the external connection type, the chain width is 6 steps of the basic parameters of the shape of the size of the scale in accordance with the table 1 of Figure 1. Note: the figure shows the definition of the original station type, use! 3.2 Structural types and basic parameters of toothed chains The marking method of toothed chains according to production requirements is as follows: Number of sections JR/T1034B2002 Example: Section = 6.35mm, chain combination form 3×4, toothed chain marking method for 60 chains: 10-5!

3.3 Technical requirements
3.3.1 Tensile test
/=3.9mm-:.28mm. Recommended: k=0.75.mn=J.0mm.
The tensile load of the chain should not be less than the requirements of Table 1: the effective chain segment should be at least 5 sections. The chain segment should be installed on the testing machine to ensure that no additional stress is generated on the chain segment. If the break occurs at the connection with the fixture, the test is invalid. 3.3.2 Pre-tension load
All the chains should be tensioned, and the pre-tension load should be at least the minimum tensile load specified in Table 1. 3. 3.3 Chain length accuracy
Put the chain after the effect on the water platform 1, and measure the length under the measurement method specified in Table 1. The chain length is generally not less than 10 links. The actual chain length deviation obtained shall not exceed 5% of the nominal size of the measured length. The length accuracy can be estimated by the basic method. Hang the chain on the matching chain wheel, and then measure the center distance between the two sprockets. The same number of related sprockets, the chain effect, the applied measurement six And chain length deviation and other requirements, the export and energy chain needs to be made! Business sales:
