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.
Inventor 2012
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 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 1 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 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 RelatedI'm trying to create a few sets of planetary gears and I'm running up against a wall here.
Both sets, for simplicity, need 1:4 ratios which makes the planet and sun gears the same size. I was using 20 teeth for the planets/sun and 60 teeth for the ring which based on my understanding of the ratios, should work. My problem arises when I attempt to get all of these gears(sun, four planets, and the ring) to mesh and rotate.
I can't figure out how to make sets of more than two gears using the Spur Gear tool. When I make the other gears on their own and add them to the system, they don't inherently mesh and pass through each other. Obviously I'm missing something here because I clearly need more than a two gear system.
As a side question, is there a method(Derived Parts, maybe?) through which I can add to a gear made with the Spur Gear tool to create a new part that will still function as a proper gear?
I want to add a twist to my inventor gear model (helical gear). I need a twist approximate 30 degree.
File attached.
I have created a 3D model of a helical gear. The process followed was to use the profile of one tooth, which by the way is a true involute shape, then displace that profile and rotate it the amount needed to equal the face width of the gear and to match the helix angle. There is also a profile located at the midpoint of the gear. The profiles are all closed polylines.
I then used the LOFT command to create a solid tooth. It looks exactly like it should. I tried to use the SWEEP command but that rotates the profile 90 deg. from the path. Extrude won't work because the path is a 3D line in space.
I then invoked the POLAR array and put 28 teeth around the center of the gear. That too looks exactly as I would expect it to.
BUT - when I try to UNION the 28 teeth into one solid, AuotoCAD 2013 stops working. And that occurs the moment the cursor touchs any part of any individual tooth. If I try to UNION the array by dragging a window over it, it stops when the window gets about halfway over the model.
The computer is a Lenovo S-30 workstation with 8 Gig of ram, an nVidia 2000 with 1Gbyte of video memory and dual 1Tbyte hard drives.
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 .

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 an ipart for helical gear.

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 1 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?

View 7 Replies View RelatedTrying to make an internal gear with design generator. I fill in appropriate info, click the 'internal' check box and when I generate I still get an external gear (using component).
Tried creating a part with the proper bore (root) diameter first and use feature...it wipes out my part and creates and external gear with virtually no bore.
I am wanting a piece of info that I cannot seem to locate in the spur gear generator. I will post a picture when I have a chance, but what I am looking for is the 'W' figure (distance over 'x' number of teeth at the pitch line). What I have is a 19.xxx deg. helical gear so the best way to get this info is calculate it, but again, I dont see it in the inventor calculation.

View 1 Replies View RelatedI have generated a gear set using inventor. Now I would like to 3d print the gears. I have uesd the export tooth shape to get the true tooth profile. now I am attempting to use the coil feature to generate the helical tooth. The problem im running into is in the coil tool I can only give it a Revolution and height dimension. The hight is the width of the gear, but I am having a problem converting the helix angle to the "Revolution" perameter. I have read other posts and they say that it is Helix angle / 360. I have tried that and then compared it to the original gear generated by inventor and it is not even close. I need to do this on in internal gear and match it to an external gear.
