Diaphragm coupling test requirements
1 Scope
This standard specifies the test methods, test specifications, test reports, etc. of diaphragm couplings (hereinafter referred to as couplings).
This standard applies to couplings whose allowable speed is 0r/min~10700r/min.
2 Terms and definitions
The following terms and definitions apply to this document.
2.1
Idlingtest
When the coupling is not applied with torque and within the allowable speed range, the coupling at a certain inclination angle rotates in both directions to vibrate.
Tests of all or part of items such as motion and noise.
2.2
Static test
When the coupling is at a standstill, torques in both positive and negative directions are applied to the coupling to test the torque and stiffness of the coupling.
Part or part of the index.
2.3
Dynamic performance test
Coupling in the rated torque, allowable speed range of efficiency, vibration, noise, torque, etc. all or part of the measurement test.
2.4
Fatigue life test
The coupling is operated at a certain inclination angle and within the range of rated torque and allowable speed for a certain number of cycles or time to test
An indicator of the life or durability of parts.
2.5
Overload test
Within the allowable inclination range of the coupling, apply a torque that exceeds a certain percentage of the rated torque to the coupling, and conduct a short-term operation test or
Continue to apply torque until the failure of some parts of the coupling to verify its safety.
3 Test method
3.1 The coupling test types are as follows.
a) Idling test;
b) Static test;
c) Dynamic performance test;
d) Fatigue life test;
e) Overload test.
3.2 The test items of each test type are shown in Table 1.
