Which gears are used in differential?

In rear-wheel drive automobiles the central drive shaft (or prop shaft) engages the differential through a hypoid gear (ring and pinion). The ring gear is mounted on the carrier of the planetary chain that forms the differential. This hypoid gear is a bevel gear that changes the direction of the drive rotation.

How do spider gears work in a differential?

The diff’s array of spider and side gears take the rotational energy from the driveshaft and help redirect it outwards to the axles and on to the tires. More importantly, they also play a key role in allowing the tires to rotate smoothly at different speeds when the vehicle is turning.

Do differentials have planetary gears?

As already mentioned, a differential gear is a special type of a planetary gearbox. One of the bevel gears on the wheel shafts can be regarded as a sun gear while the other bevel gear then corresponds in a figurative sense to the ring gear.

How do you read a ring gear pattern?

(1) Decreasing backlash moves the ring gear closer to the pinion.

  1. Drive pattern (convex side of gear) moves slightly lower and toward the toe.
  2. Coast pattern (concave side of gear) moves lower and toward the toe.
  3. Drive pattern moves slightly higher and toward the heel.
  4. Coast pattern moves higher and towards the heel.

What is a differential gearbox?

And indeed, the differential gear can be seen as a special form of a planetary gearbox (more on this later). The drive of the spider gear is of course not done by hand but by the engine. The spider gear is in turn driven by a bevel gear unit (usually a hypoid gear ), consisting of a pinion (shown in yellow) and a bevel gear (shown in orange).

How long does it take to change rear differential gears?

There are side bearings and a pinion bearing which can pit or deteriorate, causing your rear differential noise. These bearings are part of a rear differential overhaul, taking three to five hours to complete. Replacing the rear differential gears.

What different types of differential installation kits are available?

Our Differential Installation kits are available as a Master Rebuild Kit with everything you need, a Basic Rebuild Kit for the professional service shop, a Pinion Rebuild Kit with just pinion components, and a Mini Rebuild Kit when you need everything except the bearings. We also have Differential Spider Gear Kits and Transfer Case Kits.

What is the fixed carrier transmission ratio of a differential gear?

In the case of a differential gear, the fixed carrier transmission ratio corresponds to the transmission ratio which is obtained when the carrier is fixed. If one of the wheels (the “ring gear”) is rotated in this state, then the other wheel (the “sun gear”) obviously rotates at the same speed, but in the opposite direction.
