21_Gears

Transfers motion between two shafts running parallel to each other. They are characterized by their teeth, which are straight and parallel to the gears axis of rotation.

• Spur Gear

• Worm Gear

• Bevel Gear

• Crown Gear

Conically shaped gears that transmit power between shafts that have intersecting axes of rotation.

• Spur Gear

• Bevel Gear

• Rack Gear

• Crown Gear

A type of bevel gear in which the teeth project perpendicular to the gear face.

• Spur Gear

• Bevel Gear

• Crown Gear

• Worm Gear

A gear mounted to a straight rod, such that it moves in a linear fashion when torque is applied to it by a spur gear (known as the pinion gear).

• Spur Gear

• Crown Gear

• Bevel Gear

• Rack Gear

In order for two gears to mesh, they need to have the same size (and shape) teeth on the same spacing, known as what?

• Gear ratio

• Gear aptitude

• Gear pitch

• Gear crest

The relationship between the numbers of teeth on two meshing gears used to transmit motion. It reflects the change in mechanical advantage resulting from the gears.

• Gear pitch

• Tooth decay

• Gear ratio

• aspect pitch

The ratio of output force to the input force applied to a mechanism is known as ___________________.

• Pressure

• Weight

• Mechanical Advantage or gear ratio

• 3.14

____________ gears come in pairs that mate together to transfer power between perpendicular shafts that have axes of rotation offset from one another. These gears resemble screws; as they spin they turn their mating wheel.

• Spur gears

• Bevel Gears

• Crown Gears

• Worm gears

The larger the radius, the ______ force a turning wheel has

• MORE
• LESS

What is the gear ratio of a gear train with a big gear of 48 teeth and a little gear of 12 teeth?

• 1:4
• 1:3
