What are the types and ratios of gears needed to manufacture a differential?

In summary, the conversation discusses a college project involving the manufacture of a differential. The group has decided to replace the crown and drive pinion with a simple chain mechanism for easier manufacturing. They are seeking advice on the type of gears needed for the remaining components, specifically bevel gears with a helical tooth spiral. The ratios and power requirements will depend on each application and further specifications are needed to fully understand the design problem. Several sources are provided for more information on differentials and bevel gears.

Hello!

i have a project at college in which we have to manufacture a differential.
We have decided to eliminate the crown and drive pinion (from engine) and replaced by a simple chain mechanism for ease for manufacture.
However, there are 4 more gears (one each for the half-shaft, and two planetary gears) to make. i was wondering if someone could advice me about their type (e.g hellical, bevel etc, simpler the better), ratios of each, and other such info...

thanks in advance!

The gears are bevel gears that usually have a helical tooth spiral (but not always). As far as the ratios that is going to be dependent on each application. What ratio do you need for your application? What kind of power do you need to transmit through them? These are all questions you need to specify to understand your particular design problem.

What is a differential?

A differential is a mechanical device that is used to transfer power from the engine to the wheels of a vehicle while allowing them to rotate at different speeds. It is an essential component in all vehicles with wheels, including cars, trucks, and motorcycles.

What is the purpose of a differential?

The purpose of a differential is to allow the wheels of a vehicle to rotate at different speeds while still receiving power from the engine. This is important because the wheels on the outside of a turn need to travel a greater distance than the wheels on the inside, and without a differential, this would cause skidding and damage to the vehicle.

How does a differential work?

A differential works by using a set of gears and shafts to transfer power from the engine to the wheels while allowing them to rotate at different speeds. The gears inside the differential allow for the power to be split and distributed to each wheel, depending on their rotational speed.

What are the different types of differentials?

There are several types of differentials, including open differentials, limited-slip differentials, and locking differentials. Open differentials are the most common and allow for different rotational speeds between the wheels, while limited-slip differentials use clutches or viscous fluid to limit the speed difference. Locking differentials mechanically lock the wheels together for maximum traction.

How is a differential manufactured?

The manufacturing process for a differential involves several steps, including casting or forging the housing, machining the gears and shafts, and assembling all the components together. The gears and other internal components must be precisely machined to ensure proper functioning and durability. Quality control and testing are also essential in the manufacturing process to ensure the differential meets safety and performance standards.
