Complete test method
The shock absorber strength shall be determined according to the requirements of 2.3 of G9239-88, and the quality of G should be determined according to the requirements of G9289-88. The four grades of G25, G630\ and G9289-88 can be adopted.

A1.2.1 The shock absorber with the damping fluid of the oil (or other) silicone oil should avoid this test and meet the following requirements: Environmental degradation: not less than +
6) Test speed: 105%n (n, is the rated speed of the engine, t/uin: center) Test time: 10m! (small) Test results: The shock absorber covers, bolts and oil filling ports, etc., have no leakage of silicone oil. Certificate: When the connection between the plate and the element is used for reading or material damage test, NI, G, ×L, type shock absorber can be tested. A1.2.2 When the damping fluid is the engine agent (lubricant), the manufacturer shall carry out the test according to the requirements of the product technical documents. There is no need to show the lubricant seat on the cover (except the bearing). A2 Main performance test
This test should be carried out when the reducer is finalized, or when there are major changes in the structure, materials and process of the reducer that affect the characteristics of the reducer.
Main performance test should be carried out after the reducer passes the factory test. A2.1 Static torsion test
The test equipment is shown in Appendix B Figure H5. Other test equipment that meets the requirements can also be used. Only the following torsion test is required.

A2.1.1.2 Change times
Repeat loading and unloading, times, total times 2, should be less than the next time. A2.1.1.3 Loading method
Static torque stiffness is related to the speed of torque change. AI
When loading (unloading): the torque should be increased slowly (less) until it reaches the minimum torque, and then kept constant. Usually, it takes about 3mn to load (< 12.5%).

The average value of the net torque stiffness K. Calculate according to formula (A2)182 For shock absorbers with thin-walled structures, a "warning plate" should be placed on the outer shell surface. 6.3 The packaging box should be marked, and its external markings should comply with the provisions of GB191 and GB63B8. 6.4 The shock absorber should be oil-sealed (except rubber shock absorbers), the packaging should be tight, the box should be filled with moisture-proof materials, and the shock absorber should be fixed with supporting parts to avoid contact during transportation. +.
