Compressor thrust disc
Thread Content
Why is a groove provided in the middle of the compressor’s thrust disc? ! !
The surface finish accuracy for the part that fits with the shaft is relatively high, and the cost is also high; therefore, only the two ends are machined during processing.
It is unclear which groove the original poster is referring to. If it is the groove on the surface that mates with the shaft, it was designed for use with hydraulic tools for assembly and disassembly; if it is the groove on the outer circle, the main purpose of such a design is to ensure an adequate force-bearing area for the thrust disc while reducing its weight, and this is related to the design of the rotor. Please point out any mistakes!
I think the explanation on the 3rd floor is quite correct

The grooves on our engine unit’s thrust disc are located on the side, not on the outer circumference. I agree with what was said on floor 3 – it’s probably to reduce weight
