The best I was able to manage was the component on which the damper is fit/location in which it is fitted.

what are changes we need to do in the original design of a sprocket to compensate for manufacturing tolerances? how would it change the performance of sprocket?

i think that the basic principle creates noise is rubbing contact between parts.. i think there is some geometry involved in making the design.. is there some before hand information on that..

Thanks Jack action for good link that you have sent... i have tried to find good silent chain but in the design of my engine there is no provision of silent chain... only roller chain are available... can we do something on the sprocket side to remove this noise... maybe something which can...

hi. can someone help on this.. in a two wheeler automobile engine, What does a damper inside the clutch and magneto cover do... it is a rubber stripe fastened to the wall of covers..

i am talking of a two wheeler 4 stroke petrol engine. in my existing design i have a sprocket and roller timing chain.. this is not a silent chain but a roller chain and the noise is prominent at 2000 rpm. if i reduce the tension of the chain the noise level is reduced.

For adiabatic process solve by equation: w= (Cv+R)(T2-T1) is this giving correct answer?

hi there.. i think you are trying to find the stress at a section in this problem.. is this a thick or a thin section? With some calculus we can figure out what will be the moment of inertia..

hi.. can someone help me out with noise in engines.. i am specifically interested in noise due to running of chain on sprockets.. it is a sort of whistling noise... which are those parameters in design of sprocket and chain which contribute in noise.. we can also talk in terms of different...

Thanks for the response.. Ok.. All the produced cam shaft go through magnaflux inspection as it is forging root. The possibility remains that the crack was not exposed after machining. There is no visible scoring mark or sign of seizure between the gudgen pin and the small end so for now we...

On the part which remained undamaged in the block there is no mark of rubbing or seizure as such. Your point that it is quite unusual is correct as we have only received 6 cases out of around 5 lack engines we have produced, The big end is well in tact and appears to have no signs of improper...

Hi.. We have both roots for the crankshaft assembly that we manufacture. The stock removal is lesser in case of press forged component as they more accurate in dimension but as far as machining is concerned there is a little difference between the two. There can be something wrong with the...

hi.. I am new to this site. I want to know about reasons of failure of connecting rod of 4 stroke petrol engine. In this case the rod has broken into two parts from the small end of the rod. The manufacturing root of the component is hot forging - hardening - induction softening of the small...
