31、 of Apparatus8.1 Air Box Temperature Limiting DeviceAfter initial rig installation, preset the oven air temperature limit to 400F (204 C).This can be achieved by placing the insulated oven cover in position on the rig and installing the air temperature sensor at apenetration depth of 3 in. (75 mm) b
32、elow the top inner surface of the cover. Switch on the heaters and circulating fan. Adjust thetemperature control device to deactivate the heaters when the air temperature reaches 400F (204 C). This oven temperature limitmay later be reduced as outlined in 10.3 to meet rig heat-up requirements.8.2 T
33、emperature Recording and Controlling InstrumentationSince this test procedure is extremely sensitive to temperature,it is necessary to maintain a periodic check upon the accuracy of all items related to temperature measurement and control.Therefore, immediately after the installation of a new test r
34、ig, and before every set of reference tests, calibrate the instrumentationused to measure and record the air and oil temperatures against known standards traceable to NIST.22 For instance, calibrate theoil temperature thermocouple and indicating controller. This can be accomplished by immersing the
35、tip of the probe into anauxiliary temperature-controlled oil bath equipped with a stirrer. Accurately set the bath temperature at 325F (162.8 C) andconfirm the test measuring equipment to be accurate prior to testing.8.3 Gear CaseUsing the organic cleaning agent (see 7.3), clean the gear case, vent
36、tube, vent tube baffle, retainer bushings,seal sleeves, case cover plate, seal plate, nuts, studs, flat washers, baffle plate, spacer bushings, bearing bushings and clamp, keys,shaft ends, shaft nuts, and catalysts. Nylon bristle brushes, steel brushes, and long pipe cleaners can be used to aid clea
37、ning. Donot use any copper or copper-containing brushes or material as a cleaning medium. Following the cleaning procedure with anorganic cleaning agent, wash parts thoroughly with cleaning solvent (see 7.5), and finally with a volatile hydrocarbon solvent (see7.6 or 7.7), to facilitate air drying.
38、Allow parts to air dry.8.4 Test GearsThoroughly clean the test gears with cleaning solvent (see 7.5). Carefully examine the gear teeth for nicks andburrs. Do not use gears with major imperfections. Redress minor gear teeth imperfections with a fine stone or file. After finalexamination, wash gears o
39、nce more with cleaning solvent and finally with a volatile hydrocarbon solvent, to facilitate air drying.Allow gears to air dry.8.4.1 Prepare each gear with new Screen-Kut silicon carbide C-180 paper.23,11 Place a new piece of silicon carbide paper ona solid surface that has a thickness greater than
40、 or equal to 12 in. (12.7 mm). in. (12.7 mm). Saturate the entire silicon carbide paperwith cleaning solvent (see 7.5). Use one new piece of silicon carbide paper per gear side, using both sides of the silicon carbidepaper as necessary. Sand both sides of the test gears, with the required gear holde
41、r apparatus (6.1.16) on the silicon carbide paper,using a figure eight motion. Do not apply a downward force to the gear holder while sanding. Sand the gears until themanufacturers machining marks are removed. After final examination, wash gears once more with cleaning solvent (see 7.5) andfinally w
42、ith a volatile hydrocarbon solvent (see 7.6 or 7.7), to facilitate air drying. Allow gears to air dry. If the gears are not tobe used immediately, wrap them in a paper towel and Nox-Rust paper.24,118.4.1.1 Discard the test gears if not used within 24 h after polishing is completed.8.5 Test BearingPr
43、ior to installation, wash the test bearing first with cleaning solvent (see 7.5), and finally with a volatilehydrocarbon solvent, to facilitate drying. Allow the bearing to air dry.8.6 Copper Catalyst:8.6.1 Notch one strip for purpose of identification. The notch shall be triangular in shape centere
44、d on the long side of the strip.Sides of the triangular notch shall be equal and approximately 0.2 in. (approximately 5 mm) in length.8.6.2 Polish both catalyst strips on all six sides with Screen-Kut silicon carbide C-180 paper.23,11 Use either a new piece ofScreen-Kut or one retained from the gear
