I am trying to create a simulation in which a shaft rotates and the a spur gear attached to the other end rotates with it. When I apply torque to shaft, the shaft does rotate but the gear does not. I believe I have done something wrong with the constraints.

I'm not able to get the right gear rotation in a planetary gear drive that I'm working on.
If I make the ring gear stationary and rotate the sun gear, the planetary gear engages and rotates around the ring gear
but in the opposite direction of what it should be turning. The planet to sun gear engagement rotates backwards regardless of what I do to the rotation constraint that I've applied.
If I make the ring gear free to rotate, and the planet gear stationary, the gear train rotates properly.
I've attached a mock up of the plant gear system to share and show what I'm dealing with.
I have created a shaft and splined one end of it successfully. The shaft is the same diameter at both ends and I need to spline the other end as well but when I try, I get the following error messages, Cannot create iFeature. Not possible to create shaft groove. Splining the first end went without a hitch but Inventor absolutely refuses to spline the opposite end of the shaft. The shaft diameter is correct for the spline I have chosen (same as the major diameter)

I am using the design accelerator to create a shaft with multiple features. Works well. This shaft is 90"+ in length and although I realize we create in full scale, having it display into my drawing in full scale is unnecessary because one diameter is nearly 60" long. As such I would like to shorten it by using a shaft end, but cannot figure how to do it.
Just to be clear, by shaft end (term used in Mechanical) I refer to the squiggly lines that basically fudge the OAL of a component.
I am not able to convert a 2d gear to 3d gear . I have attached the 2d gear that i had created. I use Autocad student version 2012 . The gear is not getting converted into a complete solid on use of extrusion command . There are gaps in within the gear around the circle or something like that .
View 7 Replies View RelatedI have written some VB code which updates parameters in a model. I would like the code to update the shaft parameters. The shaft is created using the shaft generator. I can use a parameters to set the lengths, diameters and fillets. But when the parameter updates the length stays the same. If I open the shaft assembly, click 'edit using design accelerator' and then click 'ok' in the window the shaft updates. Is there anyway to do this automatically?, maybe through iLogic or API?

What factor of safety value the Shaft Generator program uses when you run the calculations?
Does the factor of safety value change when you are not using the inventor user material option?
Lastly, when exactly do you know when to use the density option in the calculation properties or not?
i am trying to design a shaft with a cut out that would cut along the shaft a a set angle and wrap around the shaft.
I am going to have a bearing ride along the cut out and cover this to a linear motion but can't seem to grasp how you do this in inventor 2013.
Have attached a simple assembly..i have constrained the parts but how do i get the shaft/Fan to spin inside the case?

Trying to dimension a shaft in isometric view with various diameters. I am unable to find or select the centerpoints at the ends of the shaft. This causes dimensions to be crooked. How can i get the centerpoints to display so that they may be selected?

I created several Parts with the Shaft Generator, and from one moment to another it always says that it can't update the part file with the new shaft when I press Ok.
Here is the original error, I'm german, so of cause its in german, but i discribed above what it says:

How I could go about creating a standard locknut thread, with the shaft generator (easy so far) BUT create a proper single rounded end key way? It does the end of the locknut groove with the rad that exits the shaft, but in complete truth (and 15+ years of experience.) I have never seen this done in the real world.

View 3 Replies View Relatedis it possible to produce something like in the attached image using the design accelerator? Instead of making a cylinder and sketching the spline patterns and extruding? To me there must be a way besides sketching and use the library's of standard splines patterns and sizes.

I create a engine assembly and used "Drive Constrain" to rotate the crank shaft. The animation shows the crank shaft turns continuously in one direction. However, when I animate the constrain in Inventor Studio, the crank shaft turned in two different directions (see the vide file attached).
May I know why the crank shaft turns different direction?

In any case, we found a serious problem in one of the files.Ring mount2.ipt Sketch11 there is an arc that centerpoint should be same as projected Origin Center Point, but it is not.It is actually at the midpoint of a projected line that is very close to the origin, but not at the origin.
With the common knowledge of Inventor having a Spur gear generator, please I need calling that Spur gear generator from my API. Note that I am using VB for the programming and I have use Try and Catch for linking my API to the inventor. So on starting debugging my API, Inventor starts just as the example in the my first pluggin.
The Only thing remaining is to link my API to the Spur Gear Generator.
I need to create planetary gear. Where should i start? I tried assembly with spur gear, but half of the times program crashes. when gears are made, they don't match.

View 4 Replies View RelatedI am working on a project which uses two gear reducers. I have built the gear reducer and saved it as an assembly file so to import it to the assembly of the project. When i import the reducer assembly into the project assembly, the reducer is shown as a single piece, not as a mechanism which i can interact with. But if i select, by doubleclicking, the reducer, it becomes active again. The problem is that i want to connect the reducer to another gear assembly and watch it interact.
View 7 Replies View Relatedthe .iam assembly and the .ipt parts are to follow.I'm not very concerned with the teeth meshing properly at this stage. I just want to get the rotational constraints correct first. There are two situations that I am trying to work out, and I think I took care of the first one.
Situation 1: Blue carrier is grounded.
Input: Rotate purple sun gear.
Result: red planets turn the orange planets which turn the green sun(green sun to purple sun ratio = 1:1 but in the opposite direction)
Situation 2: Purple sun is grounded (Blue carrier is released)
Input: rotate the blue carrier
Result: I want the planets to still be able to rotate, and basically be driven by the purple sun which is being held. This should then drive the green sun to rotate in the same direction as the blue carrier gears.
The issue here is clearly that the red planets will not rotate since the purple sun is grounded. What should the constraints be instead of a simple rotational motion constraint? In a perfect world, I would like to not have to ground the purple sun, and only have the purple sun rotate when I specifically rotate it. The main input to this system is rotating the blue carrier gear. The purple sun is simply a control/variant.
I'm desperately trying to model a planetary gear set.I've tried using the gear design accelerator but with little success. Essentially, I would like to have the gears set up with the planet carrier held stationary and the ring and sun gears rotating in opposite directions: URL....The first 5 seconds of this video indicate what I'm after.
I know all of the gear data, but am having trouble generating the gear set.
I am looking to generate a planetary gear arrangement similar to the picture attached. I am looking for a 6:1 ratio between the outer sput gear and the inner sun gear.
View 9 Replies View RelatedI have tried in vain to construct a planetary gear train in Inventor 2011 & the spur gear generator hasn't work much since the results are far from good, I have problems getting all the gears to fit together. The Internal gear has a diametrical pitch of d=120mm & the smallest gear a diametrical pitch of d=20mm, the outcome should produce a 6:1 gear ratio. The 3 other gears only offer stabillity, but I still need to know how I get it all to fit together with my measurements?
View 9 Replies View RelatedWhen showing a gear in an inventor drawing they look good, but showing a helical gear SUCKS! The display, I realize, is very realistic to what you would see if you held the gear in front of you at this view point or that.
Problem is, I put a helical gear drawing on the shop floor and they machinist wonder why I have two rows of teeth on the gear (since it shows the front face and the helix'd gear teeth).
Any way to remove said offending gear teeth?
