Preparation of Apparatus8.1 Air Box Temperature Limiting DeviceAfter initial riginstallation, preset the oven air temperature limit to 400F(204C). This can be achieved by placing the insulated ovencover in position on the rig and inst

32、alling the air temperaturesensor at a penetration depth of 3 in. (75 mm) below the topinner surface of the cover. Switch on the heaters and circulatingfan. Adjust the temperature control device to deactivate theheaters when the air temperature reaches 400F. This oventemperature limit may later be re

33、duced as outlined in 10.3 tomeet rig heat-up requirements.8.2 Temperature Recording and ControllingInstrumentationSince this test procedure is extremely sensi-tive to temperature, it is necessary to maintain a periodic checkupon the accuracy of all items related to temperature measure-ment and contr

34、ol. Therefore, immediately after the installationof a new test rig, and before every set of reference tests, theinstrumentation used to measure and record the air and oiltemperatures shall be calibrated against known standardstraceable to NIST.22For instance, the oil temperature thermo-couple and in

35、dicating controller shall be calibrated. This can beaccomplished by immersing the tip of the probe into anauxiliary temperature-controlled oil bath equipped with astirrer. The bath temperature shall be set accurately at 325F(162.8C) and the test measuring equipment shall be confirmedto be accurate p

Carefully examine the gear teeth for nicksand burrs. Do not use gears with major imperfections. Redressminor gear

43、 teeth imperfections with a fine stone or file. Afterfinal examination, wash gears once more with cleaning solventand finally with a volatile hydrocarbon solvent, to facilitate airdrying. Allow gears to air dry.8.4.1 Prepare each gear with one piece of Screen-Kut siliconcarbide C-180 paper.11,23Use

44、one side of the silicon carbidepaper to prepare one side of a gear. Use the opposite side of thesilicon carbide paper to prepare the opposite side of the gear.Place a piece of silicon carbide paper on a solid surface that hasa thickness greater than or equal to12 in. Saturate the entiresilicon carbi

45、de paper with cleaning solvent (see 7.5). Sand bothsides of the test gears, with the required gear holder apparatus(6.1.16) on the silicon carbide paper, using a figure eightmotion. Do not apply a downward force to the gear holderwhile sanding. Sand the gears until the manufacturers machin-ing marks

46、 are removed. Prepare the test gears prior to thecatalyst. A third sheet of silicon carbide paper may be used toprepare the catalyst strips. After final examination, wash gearsonce more with cleaning solvent (see 7.5) and finally with avolatile hydrocarbon solvent, to facilitate air drying. Allowgea

47、rs to air dry. If the gears are not to be used immediately,wrap them in a paper towel and Nox-Rust paper.11,24Start thetest within 24 h after polishing is completed.8.4.2 Discard the test gears if not used within 24 h.8.5 Test BearingPrior to installation, wash the test bearingfirst with cleaning so
