Gears and Manual Transmission Introduction

Which Manual Transmission bearings ONLY operate when the vehicle is moving?

• Rear output shaft

• Front output shaft

• Center output shaft

• Input shaft

The spur gear is:

• Straight cut

• Angle cut

• Cut on two diagonal lines

• a very quite running gear set

The Helical gear is:

• Cut with straight teeth

• Cut with a double offset

• A noisy gear set

• Cut on an angle

When a small gear is driving a larger gear you will have:

• Underdrive

• Overdrive

• A speed increase

• A torque decrease

When a large gear is driving a smaller gear you will have:

• A speed decrease in the driven gear

• A torque increase in the drive gear

• Overdrive

• Underdrive

Another name or term for Gear Reduction is:

• Overdrive

• Underdrive

• Toque multiplier

• Speed converter

In a gear set that has a ratio of 2:1. Choose All correct answers. There may be more than one.

• Torque will double from the input drive gear

• Speed of the driven gear will be reduced by half

• Toque of the driven gear will be reduced by half

• Speed of the driven gear will be double

In a gear set that has a ratio of .5:1. Choose All correct answers. There may be more than one.

• Torque will double from the input drive gear

• Speed of the driven gear will be reduced by half

• Toque of the driven gear will be reduced by half

• Speed of the driven gear will be double

On a 4 or 5 speed rear wheel drive (RWD) transmission: Choose all correct answer. There maybe more than one answer.

• 4th gear is direct drive

• 4th gear has a gear ratio of 1:1

• 4th gear has a gear ratio of .8:1.

• 4th gear drives the counter shaft driven gear.

When calculating the gear ratio on a gear set that incorporates and idler gear.

• You must use the two gear ratio math method

• You can ignore the idler gear size and calculate using the drive and driven gears only.

• You have to measure the size of the gear with a dial caliper before you can calculate the ratio

• You must know the speed of the gear first before you can calculate the gear ratio.
