Ev.{Ivan Evernden - coachwork} ORIGINAL EFC2/AD20.8.30. X7625 X7655 PHANTOM II SEQUENCE STARTER. COMPLETELY SHARP EDGED MOTOR PINION AND FLYWHEEL GEAR. Engagement tests of the arrangement of completely sharp edged pinion and flywheel gear have been made utilising our bench rig starter apparatus. Previously no such test has been made on the standardised apparatus and very little was done with completely sharp edged pinion and gear on previous arrangements. The idea originally suggesting this experiment was again to start with the simplest possible arrangement of teeth, other features being as now standard, and to rearrive by an evolutionary process at the most suitable modifications of teeth. Concerning sequence starter engagement and dis-engagement in general, we sometime back formulated a schedule of experimental tests of various arrangements of pinion and wheel assuming the use of a standard starter motor. Tests on the present arrangement have been carried out to that schedule. The nature of the several items of test and the corresponding results are contained in what follows. | ||
