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 ovencov

32、er in position on the rig and installing 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 ove

33、ntemperature limit may later be reduced as outlined in 10.3 tomeet rig heat-up requirements.8.2 Temperature Recording and Controlling Instrumenta-tion Since this test procedure is extremely sensitive totemperature, it is necessary to maintain a periodic check uponthe accuracy of all items related to

34、 temperature measurementand control. Therefore, immediately after the installation of anew 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

35、 temperature thermo-couple and indicating 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 s

36、hall be confirmedto be accurate prior to testing.8.3 Gear CaseUsing the organic cleaning agent (see 7.3),clean the gear case, vent tube, vent tube baffle, retainerbushings, seal sleeves, case cover plate, seal plate, nuts, studs,flat washers, baffle plate, spacer bushings, bearing bushingsand clamp,

Allow parts to air dry.8.4 Test GearsThoroughly clean the test gears with clean-ing solvent (see 7.5). Carefully examine the gear teeth for nicksand burrs. Do not use gears with major

43、 imperfections. Redressminor gear 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 sil

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.

45、 Saturate the entiresilicon carbide 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 t
