Hello, Anyone know how to determine the max torque on thrust bearings in a PDM? How to determine how much pre-load you need on a thrust bearing stack? Any information or resources would be greatly appreciated. Thanks

Does anyone know how I would calculate the clamping force of this piece? It is Stainless Steel.

I am needing help making the box and pin for this thread. It is 4 T.P.I. 1.25 TPF. Thanks

I am researching max possible torque for a design for a cv joint. My question is: There are ball groove type with splines and just ball groove designs. Which design would produce the most torque? If there is anything you need to know more just ask. Thank you for responding in advanced.

I am needing help to calculate the flow through this piece. I have attached a photo stating the question. Thanks for any help.http://files.engineering.com/getfile.aspx?folder=832beede-dbe4-4af5-bae1-da0a5b07dae4&file=flow_calc.jpg

Hello, I was wondering if anyone has any information on the design process for these kinds of motors? Any PDF? Resources etc... Thanks in advance. If there is anything you know about mechanical breakaway connections for coiled tubing, that would be a plus. Thank you.

Does anyone have any information on these threads? Maybe a PDF to share. Thanks

I was wondering if anyone has any information on where to get started for the design process of this type of downhole drilling tool? Any pdf's? Equations? Design considerations? Any help would greatly be appreciated. Thanks

Good morning, I am currently designing a hydraulic radial piston motor that will require 6000 ft-lbs of torque, as the end result. What I have so far is: I have 18 pistons (6 per cam) in series. I have a fluid flow of 600 gpm min. I have an inlet port of hydraulic diameter of .2832211511 in. An...

Does anyone have any resources as to where one could download these types of drawings? I find they are good practice to do in spare time. Thanks

I would like to know which resources and books everyone thinks is the best to use for MEchanical Engineering?

I have 3 shear pins 120 deg. apart connecting to concentric pieces of pipe. I want to shear the pins at a given force. My questions are: How do I calculate the shear and do the 3 pins sahre the shear load or individual. If that makes sense?

I am trying to figure out the equations needed to find max axial thrust on a single deep groove bearing (Ball Bearings 5/8" Diameter) as a function of weight on bit and rpm. What is there relationship. Any help would be appreciated. Thanks

My boss came to me this morning and asked me to do a gap study on our new design concept. I have never done one and do not know where to look to even begin. Also he wants me to conduct a flow analysis across the cross sectional area of the gap. Help... Thanks in advance.

Hello, I am trying to figure out the calculations for a shear flange. I have tried Tau=v/a. There is a thickness "t" that needs to be calculated to determine the width of the flange to shear. The material is 4140 hfs Q&T. The flange needs to shear off at >40,000 pounds of force. My "t" =.37 I...

I have a tool that uses external hydrostatic pressure and internal fluid pressure to move a piston.( In static equilibrium) I have 2 check valves inside that allow the transfer of fluid internally from one chamber to another. I also have another regulated valve internally that allows .1gpm to...
