AutoCAD Inventor :: Connecting More Than Two Gears?
Jan 18, 2012
I 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.

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.

How can I create bicycle gears that have different numbers of teeth but all have an inter tooth distance (distance between the teeth centres) of 12.7mm?
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.

I am trying to draw a bevel gears from drawings, one is a scroll plate and the others are gears with a key hole. As you can see in the following attachment.
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 have two gears. In the assembly I have them setup to mesh correctly. I can drive the constraint on the pinion and the gear will follow it (some what). 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.

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.

When we generate a gear pair using the design accelerator, the balloon from the drawing assembly only reflect one number instead of 2 different numbers. How can we change the number to reflect individual gears. Attached is the graphics.

I 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 am working on my project at home and I am having some problems with the fillet tool.
Attached is a picture of my problem with what it is doing.
I am trying to fillet A to E and E to C (B to D and D to F also)
On the left hand side when I fillet, it connects C to E instead of A to C and I do not know why it is doing that or what I am doing wrong.

As i discovered, frame generator is a very handy tool to make a frame, and to connect beams to each other.
For a customer we need to build a large frame, The outer beams are connected directly to each other. The beams inside the outer frame need to have a gap because of mounting and welding.
What i am looking for is a kind of tool, where i can add a notch, and after the notch, shorten the beam with 1 mm at each side to make a gap, which is needed for welding.
Inventor gives an error if i add first a notch followed by a Lengthen/Shorten command. How to add a notch and a gap of 1 mm to a connecting beam?

I'm using Inventor 2010 and I have a problem with connecting the sheet metal corners to each other when making round radius flanges. How to connect the corners to each other (even though this is probably not possible in reality). Even better would be if the flat pattern of the sheet metal part would also look proper.
Note that the short edges are 90 deg bent and longer edges are 75 and 105 deg bent. This also makes creating "corner fill" parts a bit tricky.

i a'm using Inventor routed 2011 and am having a issue with a revolve. I created an axis with a sketch in the part. Than i created a plane that does not pass through that axis. i sketch on that plane than try to revolve using the axis. it gives me an error. what i have is a arm3+"w x 28"l that is pivoting in the in the center and about 9" from the end it tapers out .5". The bottom is the cutting edge that i need to revolve onto a weldment for matching to keep a tight seal.

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.

Why have i got 0 for all my z values I have followed all the steps in the Guide and still have 0, my x and y axis are ok. Im wondering if it may be something to do with the Digimap and OS downloads.
Another thing, How do i conect all my drawing downloads i have together ive tried the coordinates system and just dont get anywhere.
Downloaded from Digimap i have 20 different drawings of this section but i cant connect them together. I have a catalogue system which is just like a coordinates section with these 20 places. All my drawings are fine they open in autocad fine just need to put them together to link them.

Im having a little issue with connecting lines and circles but not sure how to shorten the question to do a search on here. I have 2 concentric circles (the two circles form the walls of a round tower wall) which have 2 lines (representing a wall) passing through them. I want to join the circles from the circumference to the lines, but each time I try to do it the line seems to default to the center of the circles and to the endpoints of the lines which is not what I want. The eventual aim will be to remove a section of the circles and the lines where the new line connects to them to form an opening in the walls.
Ive tried <shift>right click and selecting tangent on the circles but I cant figure out what to do on the lines and it constantly defaults to the end of the line not to where I want to intersect the lines.

connecting two circles with different diameter into a solid. I tried loft, but it is a partial solution since it creates a surface. I know there is a solid option. There surely is a way and a simple one but i don't know how. Bellow there is a picture with diameters and length of the mast. Also i included a dwg file. Not much done there.

We maintain most of our GIS data in either personal (.mdb) or file (.gdb) geodatabases. I have AutoCAD Map 3D 2012 and want to be able to connect to these geodatabases. Where can I find the FDO provider to connect to these types of geodatabases and what is the process for updating the providers list for AutoCAD?

I'm using Windows 7 (64 bit) and I have to connect a file (.mdb) created with Microsoft Access 2007 to my Autocad Map 3D 2011 draw. I uninstalled Office, installed the AccessDatabaseEngine_x64.exe and re-installed Office. Then I followed step by step the process shown in the video here with ODBC but it doesn't worked for me. It says "test connection succeeded" but when I attach the database, it comes up with a red "X" symbol next to it.

As you can see in my attachment, I have a emergency spillway coming out of a dugout wetland. The fill area, the pool area, and the emergency spillway channel are all separate surfaces. All three of these surfaces are created from gradings. The fill was a feature line drawn around the top witdth of the dam, and then graded down to the Existing Ground. The channel is another polygon feature line with elevations at each PI and then graded up to the EG. The pool was a feature line I drew around the perimeter of my pool, laid on the surface EG, and then graded down to an elevation on a slope.
I'd really like to blend all the surfaces together. Right now, they are all separated with tiny slivers of Existing Ground.
How do I go about this? As you can see, I'm still pretty green with gradings.
