How to draw a turbo compressor wheel in solidworks

all right so I've decided to make a little tutorial on how to draw a compressor wheels for turbochargers haven't found any good tutorials out there all the other ones I've seen they don't really look too nice and they don't really look like what you'd find on an actual turbocharger so here I am showing you how to do one so basically you want to start drying on the front plane draw a nice little center line down the middle for reference and for the revolve that we're going to make it a second so basically I want to set the height of my compressor real first by this line parallel to the coincided with the center line I just drew so that's going to be 50 millimeters not really drawing this based on a real compressor wheel just to my dimensions I'm going to make it 44 45 let's say so it's 90 millimeter X deucer 45 radius on that on the top I'm going to make the center roughly let's say seven millimeters and then I'm going to make an arc right here actually no that's not right all right let's make a this is for a super bad compressor real I'm just doing this little extra thing here so I'm going to do four millimeters here just cause a super back compressor wheel basically the bottom isn't the base isn't flat it has a little as a little arc here if that makes sense to make the back of the compressor wheel I if you know turbos you'll know what I'm talking about we have basically that's just going to be my profile for my center cone and we're going to do a revolve boss/base should create this if not you got to select your axis of revolution as the center line here and then you have to have your clothes profile there so there's our center cone that's very basic that's how it looks from the side there's no super back profile yet I'm going to revolve cut that later so next thing you want to do is create a plane on the bottom so reference geometry plane and then make it zero zero millimeters spaced away from the bottom so it's like that and then I'm going to want to view the bottom face like so and now all we have to do is select this plane we can do a three-point arc this is very rough if you want to make a really nice looking compressor wheel you're going to have to do it a bit differently you're gonna have to actually measure everything I'm just kind of drawing this free-handed so this right here is going to be the curve of the bottom of the blade so the part that scoop will in this case it doesn't scoop air in it kind of throws air out to the side so you want to make it curved like this so yeah that's about good and then the next line here I'll make a line just to make it a proper dimension just do it like this so this line here specifies the thickness of the blade at the bottom so I'm going to do a 1.5 millimeter thick blade so I'm just going to do 1.5 millimeters here - it's not exact by any means but you get the principle so basically I can draw another arc right here and make that roughly the same if you want you can draw other lines in between here just to make it more exact but that's basically it for the bottom so that's the blade profile for the bottom very simple fact isometric view here that's how it looks I'm going to go ahead and exit the sketch so right now we want to make another plane for the top which is going to be right here we want to make it right up against the top again and then we can view it from the top view now right here you want to the top of a compressor wheel the blades the edges are usually squared like they're squared off they're not curved like at the bottom so you can just use a rectangle it's a very easy so yeah we're drawing on plane number two I'm just going to go ahead and make it right up to the edge because we're going to revolve cut this entire thing after and the thickness at the top I'm going to make it like 0.8 millimeters very very small oops I messed that up so for this line you want to take the relations out want to remove the vertical vertical here I want any relations for these lines because I just want to free free free drag it essentially so coincide in for this point delete that delete the horizontal there we want this point coins to coincide it because you want to rotate around the axis but I'm just going to drag it around like this just because it's easy this point here will automatically coincide with the edge there and yeah so I'm just dragging it like that just to make it relatively the right angle away from the bottom so once that's done you can exit the sketch again and then for here this is where you're actually drawing the blade profile the blade how to put the loss of the blade that makes any sense so I'm doing a 3d sketch with hang on I keep exiting it so 3d sketch with an arc I'm just going to draw a line from this point right up to this point here and it's basically going to be a nice curve like that you can see that there this isn't very exact you can draw it on a plane you can make a plane that you can draw this arc on to make it precise but you don't have to this is just the way I like to do it just for oh this is tutorial purposes but I'm gonna exit that sketch here now we're going to go to lofted boss/base and it already selected this line as a guide curve so we can select the bottom profile here and then the top profile and show draw us a nice blade like that a nice loft so once you have that and you're happy with it you can finish it and that's one of your blades so to do the rest of the blades you want to click that blade and then go to circular pattern and then I'm just going to re show my my sketch one well I did that too soon but basically what I did there that selected sketch one because they had a setter line as a revolved base for the blades this is only a six blade I want to be a twelve blade so I'll do that again so selecting the features and faces Loft one for our circular pattern and then parameters right there for the axis of rotation we want to show this axis so right now I'm selecting the centerline right here so it's going to revolve around that center line and then basically I want twelve blades so I'm going to type in twelve here 360 degrees of rotation and then there are our compressor blades so now to get the actual shape of a compressor reel what you have to do is go to front view and then I like to do section view and cut it in half and right here you can actually draw the profile of the blade you want to cut it like revolve cut out of this drawing right here so you can select the front plane to draw on and then basically you're going to draw all the parts that you want to cut out of the drawing so like I was saying before this is going to be super back blade so the bottom base let's say say eight millimeters here and then this is going to curve up to about you know some sit and being really approximate this is about here we don't want to revolve cut this spot right here actually maybe we do we want to make the blade stick out a bit so I'm going to do it to about there and draw this line up to about right here and then I'm going to draw another center line or draw another line with the center line draw it out to about here draw another one slightly down so the blades don't go all the way to the edge I'm going to draw this line to about okay hang on let's just see how wide this is actually going to be so that's going to be so I want to be a sixty millimeter so it's thirty out sorry about there again this is very approximate this isn't how you should actually draw a real compressor wheel if you're actually going to machine it and here is our curve or blade profile again and then in order to cut this out we need to draw a line like that go all the way around come down go to here and then connect it with the thing so basically we're cutting all of this stuff out in this area so I don't even have to exit that sketch I'm just going to go straight to revolve cut and select axis again right there selected contours this and then there we go select just that region and then it's going to select the circumference circumference it's going to select the 360 degree shape of what we drew here I apologize if I'm not making any sense but yeah so basically that's our cutout compressor wheel it's a looks kind of weird it's not really the exact shape that you'd want but it's got extended tips this is really useful for modern compressor wheels because it gives more flow so yeah basically that's that another thing that I'm going to do is on this plane at the bottom I'm just going to draw a circle to extrude as the shaft hole well the hole where the shaft goes through essentially so I guess I'll make that around three millimeters in radius so six in diameter then we're going to do extruded cut and then through all and then there we go there's our hole in the top of the compressor and then I'm going to hide the planes I'm going to hide all my drawings just so you can see that better and basically there's a compressor wheel just like that very easy to draw okay so here's a better drawing of a compressor wheel this one actually has six plus six blades instead of just twelve to draw this basically you do you know how I did the one blade profile just the top plane and then the bottom you can make another plane in the center and then you can draw another arc on the bottom on another flat spot here and then do that you can also fillet the edges like I did here to make it real nice and aerodynamic you can also do a lot of other cuts this is just the prototype wheel so yeah there's a lot of ways to do it if you need any help you can comment below or whatever I'm not really a pro at SolidWorks but uh I learned how to draw compress reels on my own and I feel like a lot of people could benefit from this video all right so thanks for watching
