2. Differential (mechanical device) - Wikipedia

   en.wikipedia.org/wiki/Differential_(mechanical...

   Spur-gear differential. A spur-gear differential has an equal-sized spur gears at each end, each of which is connected to an output shaft. [8] The input torque (i.e. from the engine or transmission) is applied to the differential via the rotating carrier. [8] Pinion pairs are located within the carrier and rotate freely on pins supported by the ...

3. Spiral bevel gear - Wikipedia

   en.wikipedia.org/wiki/Spiral_bevel_gear

   Spiral bevel gear. A spiral bevel gear is a bevel gear with helical teeth. The main application of this is in a vehicle differential, where the direction of drive from the drive shaft must be turned 90 degrees to drive the wheels. The helical design produces less vibration and noise than conventional straight-cut or spur-cut gear with straight ...

4. Bevel gear - Wikipedia

   en.wikipedia.org/wiki/Bevel_gear

   Bevel gears are used in differential drives, which can transmit power to two axles spinning at different speeds, such as those on a cornering automobile. Bevel gears are used as the main mechanism for a hand drill. As the handle of the drill is turned in a vertical direction, the bevel gears change the rotation of the chuck to a horizontal ...

5. Limited-slip differential - Wikipedia

   en.wikipedia.org/wiki/Limited-slip_differential

   A limited-slip differential (LSD) is a type of differential gear train that allows its two output shafts to rotate at different speeds but limits the maximum difference between the two shafts. Limited-slip differentials are often known by the generic trademark Positraction , a brand name owned by General Motors and originally used for its ...

6. Hypoid gearboxes - Wikipedia

   en.wikipedia.org/wiki/Hypoid_gearboxes

   Hypoid gear sets have long been used in the differential of rear-wheel drive cars, trucks and robotic arms.The scope of misalignment between the centers of the two interlinking shafts permits utilization of larger sized gears which enhances the contact surface area and reduces the wear and tear on the gear hence extending the life and power transmission capabilities of the gearboxes.

7. List of gear nomenclature - Wikipedia

   en.wikipedia.org/wiki/List_of_gear_nomenclature

   The module is the measure of gear tooth size which is normally used for metric system gears. It is similar to the Diametral Pitch (DP), which is commonly used for UK system (inch measure) gears but they differ in the units used and in that they bear a reciprocal relationship. Module is the pitch circle diameter divided by the number of teeth.
