Significance of snap rings in a turbo

In summary, snap rings are used in turbocharger core assembly as a cheap and effective means of holding bearings and seals in place. They are an important part of the design process as they help to address concerns about dimensional changes with heat and stress, as well as vibration. These snap rings are made of varying materials and can hold together different parts of the turbo, including the compressor housing and journal bearings.

Hmmmmm. Sorry if this sounds like a smart a$$ answer but if they are there I am sure it is for a good reason. Like to hold it together?

They hold bearings in place and are easily installed. Rods/shafts have to be passed through casings and turbo internals before the bearings can be installed, so the best way to hold bearings in one spot is to use snap rings.

They are very important.

You have already heard good answers. Snap rings are cheap and effective means of holding such things as bearings and seals in place.

But a general comment about turbo machinery is probably in order. Two things cost probably the most in the design phase. They are how things change dimensions with heat and stress, and vibration. Often, at least part of the solution to these concerns will involve a snap ring rather than some other retention device.

Snap rings that hold the housings together or snap rings that hold the bearings?

well i happened to see a turbo being assembled ..thats where i saw snap rings ..what material are they made of ..and do you mean to hold together the journal bearings ?

On my 3000gt VR4, they hold the cold side compressor housing on as well as the bearings.
 

FAQ: Significance of snap rings in a turbo

What is the purpose of a snap ring in a turbo?

A snap ring is a type of retaining ring used to hold components in place on a turbocharger. Its purpose is to secure the turbine and compressor wheels onto the shaft of the turbo, ensuring they rotate at the correct speeds and do not come loose during operation.

How does a snap ring affect the performance of a turbo?

A snap ring is an essential component in a turbocharger, as it helps maintain the balance and alignment of the turbine and compressor wheels. If the snap ring is missing or damaged, it can cause the wheels to shift or become unbalanced, resulting in decreased performance and potential damage to the turbo.

What are the different types of snap rings used in turbos?

There are two main types of snap rings used in turbos - internal and external. Internal snap rings are inserted into a groove on the inside of the turbo housing, while external snap rings are placed on the outer edge. The type of snap ring used depends on the design and manufacturer of the turbo.

How do you install a snap ring in a turbo?

The installation process for a snap ring in a turbo can vary depending on the specific model. In general, the snap ring should be placed in the designated groove on the shaft, and then compressed and inserted into the housing. Specialized snap ring pliers or tools may be needed to properly install the snap ring.

Can a snap ring be reused in a turbo?

In most cases, snap rings should not be reused in a turbo. Over time, snap rings can become worn or damaged, leading to potential failure and damage to the turbo. It is recommended to always replace a snap ring when performing maintenance on a turbocharger.
