Thank you for the responses. I'm using 20dp gears, #teeth=24 on input & output gears and 18 on the idler. Gear material is 1117 steel, hardened to 50Rc. I want to avoid the use of bearings or bushings for economic reasons. Lubrication is not used.
Due to relatively large clearance (about .004...
Dear friends,
I am designing a gear train using 3 in-line spur gears. These gears are supported by 2 parallel plates. I do not have any ball bearings or bushings. Input & output gears have hubs which rotate freely inside the plate holes; whereas the center gear rotates over a fixed shaft.
I...
I am designing a simple spur gear train. Goal is max output torque & high efficiency. OD of gears is pretty much fixed.
Could someone please suggest what would be the optimum pitch which I could consider? I am thinking 12 or 16 dp. However, I am not sure how much of a friction loss there will...
Dear Friends,
Thank you for your responses. I am still trying to find out if my mesh is refined enough to give good results. I am also trying to use the mesh convergence in the area of interest, which is a fillet. I'm seeing that as the mesh is refined more and more the % error increases. At...
Thanks for your response. The contact is between a concave surface and a convex surface. So, it is a line contact. I agree that the theoretical stresses will be infinite due to this. But then, is there any other way to analyze this except by creating an area contact.
I am not aware of the...
Dear Friends,
I am trying to find out if the mesh refinement in the area of interest is good enough to give me good results.
This is what I tried initially. I ran the model with a reasonably refined mesh in region of interest. I noted 1) max equivalent stress and 2) the average stress in that...
I want to find strength of a spot welded joint using Ansys Workbench. The weld needs to be flexible.
If modeling of flexible spot weld is not possible in workbench, how do I model it in classic Ansys.
Any ideas or suggestions would be very helpful to me.
Thanks.

Hi Greg,
Thanks for your valuable advice. I don't know how to deactivate a fixed joint after a certain time interval. If you could give me more details on this, that will be very much appreciated.

I'm having difficulty in defining a displacement/velocity constraint on a part. I want this particular part to be stationary from time = 0 to time =.005 seconds; then, the part would rotate and move axially based on a certain spring force. Can anyone please give me suggestions?
I'm looking to find a manufacturing process for MASS production of a steel tube. OD is 5mm and wall thickness is .35mm.
Any ideas/suggestions will be appreciated.
Thanks.
