16 teeth for driver 32 teeth for driven with a 6 dp

16 teeth for driver, 32 teeth for driven with a 6 DP
32 pitch for driver, 64 teeth for driven with a 12 DP
5. Pitch: 6
5. Driver HP= 7.5
Gear Type= spur gear
7. Driver= NSS616
Driven= NSS632
Post Lab Exercise
1.
a.
Mutually perpendicular: Miter gears, worm gears,
b.
Parallel: Spur, helical
2. 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.
