Gears

Question 1

is a machine
element of a mechanical
system formed by mounting
gears on a frame so the teeth
of the gears engage.

Answer 1

gear train

Question 2

Usually,the first gear that is attached to the motor shaft

Answer 2

Drive Gear

Question 3

the second gear is a “___”
attached to the load shaft.

Answer 3

driven gear

Question 4

How to find gear ratio?

Answer 4

1.Count the number of teeth on
the drive gear.
2. Count the number of teeth on
the driven gear.
3. Divide the driven gear
teeth by the drive gear teeth.

Question 5

how to pronounce this in gear ratio?

3/2

Answer 5

three to two

Question 6

what does it mean in terms of turning(revolutions as well as speed or rad/sec)?

Answer 6

the driver must turn 1 and a half times to make the driven 1 full revolution means also that the larger gear that is the driven will turn more slowly

Question 7

what if the gear ratio is inverted

Answer 7

The read is two to three

means that the driver is larger
but turns two times while the driven which is a smaller gear turns three times

also means that the driven is much faster than the drive

but the drive has more torque

Question 8
