Report of Test on Gearbox, WesTech Gear Corp,, Model 1321: Production Test,
Abstract
The purpose of the test was to determine the proper assembly and general running performance of the test unit, a Model 1321 Speed Increaser. The test equipment was brought up to 2700 rpm and run for two hours after the oil inlet temperature was stabilized at 180 Degrees F. Readings of unfiltered housing vibration, oil temperature, bearing housing temperature and oil pressure were recorded at half-hour intervals. The coupling arrangement used in the test, made necessary by the test equipment, was unlike the intended installation of the test unit in that the input shaft supported most of the weight of the jackshaft coupling assembly. Much of the pre-test was spent field balancing this assembly to minimize its effect on the housing vibration which initially was as much as 5 mils transverse at 1500 rpm input. The brace between the test unit and the slave gear was decided on during the pretest to provide a more rigid mounting arrangement. The pump suction port was improperly oriented at assembly and was corrected. ALso, substantial leak from improperly tapped plugged holes was noted during the pre-test and corrected by assembly prior to the test run. The recorded results of vibration, temperature and oil pressure are included as Exhibit III. Performance falls within acceptable limits in all areas.
