Is there any way to draw built in gears by gear generator in Inventor? I mean, I need to create a spur gear around a solid body and then it is gonna be processed directly onto the body during manufacturing.
View 1 RepliesI have two sets of identical spur gears. I want them to be lined and connected big-small-big-small gear. But how to connect this two sets together. I can create motion and axes constrains but it still lacks teath meshing. I found some tutorial how to create differential drive, it works with downloaded gears but not with one that I create (it says to set imates to visible which does nothing and alt-move mesh imates toghether which also do not work). I work with 2009 and 2011 versions.

My attempt at a solution and problems encountered:
I made a bicycle gear by patterning a small circle around a large circle then trimming lines (see attached sketch), but this method requires me to estimate the diameter of the large circle before patterning and then keep modifying this slightly until I get an intertooth distance as close as possible to 12.7mm. So I can't get exactly 12.7mm. In my sketch I have labelled this intertooth distance I refer to by construction lines.
I'm trying to design a gear system wherein a small gear rotating on an axle interacts with a large gear, held on an arm. The arm rotates about the same axis as the small gear, in the opposite direction. I applied the relevant motion constraint between the two gears. When I rotate the arm, the motion of the large gear rotates the small gear. However, if I just rotate the small gear, it freewheels, and the large gear doesn't move at all. This is a problem, because the machine depends on the independent rotation of both gear and arm-- the small gear has an input applied to it, but if I try to rotate it it has no effect on the large gear. I assume this is to do with the fact that the large gear's axis of rotation moves with the rotation of the arm.
I can't just throw it all into dynamic simulation, because I don't know yet what kind of torques will be rotating the arm and the small gear-- I know how they rotate relative to each other in terms of degrees, but that's all.
Essentially what I need to do is make it so that rotating the small gear turns the big gear, even when the arm is free to move (when it's grounded, the gears turn normally). I thought about using a contact set, but the gears (generated by Inventor) actually slightly intersect at the teeth, so that doesn't work.
how we can design a set of internal gears?

My question is how do you draw bevel gears on the face of the scroll plate and the cylindrical face of the other 3 gears?
I'm given this data to generate my worm gear set with:
Worm Gear Data:
Diametral Pitch: 8
Number of Teeth: 27
Pressure Angle: 20 Degrees
Pitch Diameter: 4.219
Base Circle Diameter: 4.523
Circular Pitch: .491
Circular Thickness: .246
Root Diameter: 3.906
Face Width: .783
Worm Data:
Number of Threads: 5
Pressure Angle: 20 Degrees
Pitch Diameter: .938
Lead Right Hand: .375
Lead Angle: 169 Degrees
Addendum: .156
Whole Depth: .313
Chordal Thickness: .204
Inner Diameter: .619
Outer Diameter: 1.244
Center Distance: 5
My problem is it keeps changing data and/or failing. It particularly hates the 27 teeth (always changes it), never shows a 5.4 gear ratio (probably because it hates the 27 teeth), and won't accept an addendum of less than 1. Is this feature limited to only certain set gear setups? the automated tool won't accept these values (which I have to work with)?
I am having a problem while making 2 straight spur gears. The purpose is to connect the crankshaft with the camshaft. Center distance is fixed: 85,5mm. I would like a ratio of 0,5 with 22 and 44 teeth. My gears seem to hit each other. Please find the attached pictures below for a detail and my inputs.

I wanted a better video of it, so I went into Studio. Now when I drive the constaint like before on the pinion, the gear goes crazy.

There is a rotational translation constraint set between the pair (= to inverse of gear ratio) that works in the iam, but it is like Studion ignores it. How can I animate this to show the gear mesh?
Is it possible, using Design Accelerator to have Bevel Gears with straight teeth? I've tried every combo I can think of, and they are always curved teeth. Gears are not my most knowledgeable subject. I usually have the engineers produce the specs, & I get to draw them - they are not happy with the pictorial results.

I made internal gears with design accelerator.
It's calculation is OK. And drag it,the rotation is good, But the direction is opposite. The tooth's move opposite direction to each other.
I used Autodesk Inventor 2013, And sp2, update DL22436649.zip But, this appeard before And after sp2 patch.
I'm trying to draw a spiral bevel gears system KLINGELNBERG , but the results do not match the actual measurements of the piece.
ex. measure of the real outside diameter of the gear = 356mm
DATA :
number of teeth pinion = 9
number of teeth gear = 44
module = 5
shaft angle = 90 °
face width = 59mm
helix angle = 35 °
pressure angle = 20 °
I'm trying to run a simulation of 2 bevel gears without using the transitional/rotation constraint, but using the contact between the surfaces to simulate the rotation of the gears - basically I have an L-shaped shaft running through both centers and want to have the upper gear grounded, make the lateral gear rotate around its own axis - the goal is simply to see the contact between the gears make the side gear rotate around the vertical part of the l-shaped shaft, due to the contact forces.

View 1 Replies View RelatedI am creating a couple of spur gears using the "Center Distance" design guide. I have fixed each gear to a cylindrical face, but when I click on the "Calculate" button, there is an error saying that the center distance is incorrect.
I went back and edited my sketches so the center distance matched the one displayed in the design accelerator and attempted to calculate again, but the error persists. What am I not getting here?
I'm trying to make some 3d spline gears in autocad, I start by generating them in eMachineshop then importing into autocad, this works fine but the gear is imported as seperat lines so I can't extrude them, i also cant join the lines because after zooming in there are quite a few gaps. How I can join the lines together without manually connecting the dots? I'll include a copy of the gear, eMachineshop only outputs dxf files as far as i know.

Not sure if this is a coincidence but this has only just started happening since updating my Adobe Reader software to the very latest XI version just released.
I have sent several error reports to Autodesk but can't see any in the support section. I have tried un-installing the Acrobat Reader software and AutoCAD still crashes out. Creating PDF's from external printers like PDF24 have no issues but prefer the inbuilt printer as it keeps the vector data and layering info in the resultant PDF.

We're using a precise level to as-built and create a dtm of a floor. The client would like us to assess the dtm for changes of grade greater than 3mm over 3m. (The test is based on walking around the floor with a 3m straight edge and 3mm blocks - see Figure 6 in this paper .)
Please note that the floor could be laid on a slope and still comply - it's the grade changes we're looking for. And some of these floors are large so we'd prefer make it as automatic as possible.
As far as I know there's no surface style that can display grade changes. We can shade each triangle by slope, but it will still require manual visual inspection to see if adjacent triangles are sufficiently similar to comply.
I left site, we are as building structures. When I id the current info, I have x and y co-ordinates but z values are 0, and when I try edit the z value it wont allow me to apply the new level .

Having issues with data shortcutting custom built structure parts? I built a very simple part that has no dimensions and is for plan appearane only (it is a just a rip rap outfall). The part seems to work perfectly in my design file, appearing exactly as I desired with automatic labeling. However, when I data shortcut the pipe network into the plan presentation file, all default pipes and structures are brought in except for the custom built rip rap outfall.
I have tried to delete and reload the data shortcut, changed the part properties, and made sure the parts lists and styles are the same in both drawing files. If I swap the custom part out (in the design file) for a default part, the default part is suddenly displayed in my plan presentation file after synchronizing. It is as if the data shortcut doesn't recognize the custom part, even though it is in the network parts list?

Am using Photoshop CS5.1, Simply want to create a single picture (file) that has a "built-in" mat around it. Seems like all that's needed is a box in background (color it as a mat), then put the picture on top.
Problem is, when I go to size (or crop) the picture, it changes the size of the mat and Canvas Size. "Really" want the Canvas Size to STAY 16in x 20in, just makes it easier so can SEE and adjust (move, crop, slide arund) the picture to be 13in x 17in in the center or whereever. After all done, will save as jpg, so can view/print easily.
