3 Method Summary
Add a certain amount of samples to the gear box, and make it operate for a certain time at the specified temperature, load and rotation rate. The shear stability of the sample shall be assessed according to the permanent viscosity loss caused by the mechanical shearing action during the test.
4 Equipment and Material
4.1 Equipment
4.1.1 Gear testing machine (model CL-100 or FZG): It shall be modified in accordance with those specified in Appendix A (Additional) of this method.
4.1.2 Test gear: Model QCL -003 (made in China) or model FZG “A” (made in the Federal Republic of Germany) with a specification corresponding to Appendix B (Additional).
4.1.2.1 For each face of the gear, 20 times shearing tests may be conducted at the most. If the face of the gear is damaged, the test is invalid.
4.1.3 Pipette: 25mL.
