Is there any book or internet source available where I can find a formula for finding natural frequency of vibration of a shaft?
I found ageneral formula f = sq root of(Stiffness/mass) . The question is "How to calculate the stiffness of a member?"
I am lookng to Calculate torque for a gasketed connection on a gerabox with an oil under pressure no more than 8 psi.
This connection is a drain plug with plug size M20 and a copper washer to seal the joint. I have the cacualtion formulae for steel connections and bolts but not for copper...
I received a drawing of a gear from a customer. On the left side he has drawin a front view of a gear. He has taken a section at 15 deg to horizontal and shown that in the middle of sheet. And on the right side he has drawn the back view of the left hand view. He has not named it as such on the...
Does any body know which standard is used for calcualting and specifying the specific sliding ratio for an external gear pair?
I know that this is a ratio of sliding velocity to the rolling velocity and is an indicator of the scoringg and noise generation.
Hello
I am assessing a design of a small gear box for manufacturing. I noticed that if I follow the dimensions to the print for the shaft groove location lengths and the gear face width ( gear to be press fitted on shaft) then I end up with 0.010 Max. Intrerference to 0.020 max. clearance...
I tried to do a search for getting some hlep in converting a metric dwg to inch. I did the first part of scaling the diemsnion by 1/25.4 and converting the actual diemsnions to inch. But the dimension value displayed against that particular diemsnion does not get changed. Is there any way to do...
I am looking for this book but on all the websites I serached it is referred to as out of print.
Does anybody know of any used books seller in North America where I can buy this book.
I am evaluating a gearbox design received from a manufacturer and I notice that the mislaignment is about 8 minutes and the bearings used are deep groove ball bearings with C3 clearance. Manufacturer recommends max 10 minutes of mislaignment. The design is within that but it is usually advisable...
I wish to specify "Electroplated Zinc coating plus Yellow Dichromate" specification on the drawing. I was looking for a standard thickness spec for such a coating.
I researched the web and machinery's Handbook for this and it looks like ASTM B633 is the standard being followed.
IS there any...
We have 8620 Hot Rolled annealed material 8.5 inch dia. We finish turn it to 8.448 Gear OD in soft turning. In the recent supply we found that atleast 15% parts showed cracks on the OD after soft turning. I know that we have to use a bigger bar size to leave more allowance for finish turning...
Does the thread get stripped only beacuse it is case hardned to 0.02/0.03? All other things remaining same.
Thread size M20. Does the same logic apply to internal and external threads?
WE have one appliocation for steering shaft for material handling equipment. Due to difficulties observed in shaping blind splines in 4140 shaft ( H/T to 28/32 HRC) we are changing it to broaching one end ( 3 inch long) and welding it to the other long end ( about 13 inches long).
My main...
I am aware of the fact that we can use a Lft hand hob for Right hand gear and vice versa. But how do the machine accuracy and backlashes affect this process? Do the LC 382 liebherr CNC hobbers do the reverse hobbing without a proble?
I would appreciate the response.
I am looking for an indicating dial bore gage for checking dimension between balls for internal gear. The existing gages in the market are very costly and are relevant for only one gear data.
Just wondering if we could convert the standatrd Mitutoyo dial bore gages to check the dimension...
I have a question about grinding a shoulder and cylindrical diameter. I guess an undercut is essential in a prior turning operation so that in grinding the corner breakdown does not occur.
I have searched a lot of technical articles on the internet but could not get any which specifically...
We are having a 8620 gear forging which we are gear cutting prior to heat treatment. Then we are cutting internal splines to ANSI class 5 and then sending it for carburise and hardening to 57-60 Rc.
The perfectly OK spline is increasing in size by almost 0.005" between pins. We purchased the...
Could any body help me in deciding what fit is supposed to be used between a shaer pin and mating hole. This connection is supposed to drive a torque. I do not know the value, as it is customer design.
Pin is made of material 96 ksi and the driving member is made of UTI 116 ksi. Nominal dia of...
I was just wondering if there is any software out there which could be used to test the rolling of rack and a gear of known data.
WE are having gear and a rack of 14.5 degree Pressure angle and 20 DP but do not seem to roll properly. Individually both are good in dimensions but seem to have...
