16 teeth for driver, 32 teeth for driven with a 6 DP32 pitch for driver, 64 teeth for driven with a 12 DP5.Pitch: 65.Driver HP= 7.5Gear Type= spur gear7.Driver= NSS616Driven= NSS632Post Lab Exercise1.a.Mutually perpendicular: Miter gears, worm gears,b.Parallel: Spur, helical2.An idler does not affect the speed ratio 3.The teeth of helical gears with parallel axis have line contact. This provides gradual engagement and continuous contact of the engaging teeth.
4.Both are constructed by combining 2 identical helical gears of same module and pitch. The main difference is that there is a groove between the two in a double helical. In a herringbone, the two helical gears are flush with one another.5.a.Root diameter: The smallest outside diameter of a roll tool; the part of the tooling that makes contact.b.Backlash: the amount by which the width of a tooth space exceeds the thickness of the engaging tooth on the pitch circles of two gears.c.Tooth profile defines specifications related to the gear tooth, i.e. module, pressure angle, etc. Examples include standard basic rack tooth profile and involute tooth profile.
