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 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 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.

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?

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.
View 3 Replies View RelatedI 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?

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.

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 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 have an inside web plate sketch that i want to offset but my offset does only do one line at a time.
So my problem basicly is that I want it to do the whole sketch in one click. Is it possible to join all the lines? or is there another function that I do not know of that will do this for me.
Attached is photos of the problem I have
1 picture - How do I join these lines
2 picture - How the whole sketch looks
3 picture - The offset does only do one line at a time (i want it to do the whole sketch)
i have a photo with a line near a teeth model which i need to measure. i have attached photo to autocad but how can i setup the real world scale so my measurements will be accurate?

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.

I know it has something to do with the settings, but can figure out what the correct settings are...
I'm seeing a very strange behaviour with the routing though. In the first picture you can see both connection points are lined up in the y plane (measuring 0mm). However in the second picture you can see the route inventor choose for me which is strange. It shows the path moving in the "y" direction before returning in the same direction at the next connection point. I've plenty of room for all bends and piping (I'm using ANSI Schd40 1.5NB - Welded ends). I've tried doing the route manually then connecting the top horizontal section but it again wants to throw an offset or two in there when there is no need.
