Introduction
1. Standard Overview
GB/T41947-2022 "Fatigue Test of Multi-V Belts for Belt Drive Automobile Industry" is a dynamic test method for quality inspection of multi-V belts (PK type) used in the transmission of auxiliary equipment of internal combustion engines such as automobiles. This standard is mainly applicable to fatigue performance testing of multi-V belts for transmission in the fields of automobiles, engineering machinery, etc.
2. Background of Standard Formulation
With the development of the automotive industry, the requirements for transmission systems are increasing. Multi-V belts are widely used in the automotive industry due to their structural advantages, but their fatigue life is an important factor affecting the reliability of transmission systems. This standard is modified based on the international standard ISO11749:2014 and formulated in combination with China's actual situation to standardize the fatigue test method of multi-V belts.
3. Comparison of standard frameworks
| Dimensions | Content of this standard | ISO11749:2014 | Difference analysis |
|---|---|---|---|
| Structure numbering | Clearer chapter division, new detailed description of test methods | The structure is relatively simple | This standard adds graphic illustrations to improve operability |
| Technical indicators | The material of the pulley used for the test is GB/T34484.1, and the hardness test complies with GB/T230.1 | The material standard is not specified | This standard adapts to domestic technical conditions |
| Scope of application | New test conditions for 3PK multi-V belts | No specific test parameters included | This standard is more targeted |
4. Implementation suggestions
To ensure the accuracy of the test results, it is recommended to:
- Select test equipment strictly in accordance with the standard and calibrate it regularly
- Select a suitable testing machine (four-wheel, three-wheel or two-wheel) according to the belt length
- Understand the failure criteria and judge the test results in time
- Record a complete test report for inspection
