hiiiiiiiiiii............

i 😕am having problems with rack and pinion calculatons.................can ny i plsssssss give me the formula in terms of pitch of the rack and the no. of teeth
of the pinion. i need to findout the teeth spacing on the rack and pinion........... that can help me calculate the distance moved by the rack for 1 rotation of the pinion...........
thanx.............😛
@Tkelly • 01 Jun, 2009 Without knowing the load to be moved, you can not decide the pitch of Rack & Pinion.
Also mention the distance of the rack you required to mave by one revolution of pinion.

@hinduja.prasad • 01 Jun, 2009 ok....thanx for the reply but the problem is i am using this steering and i have a particular steering ratio in my mind. and yes i also know the total rack length and dia of the pinion. so can u plsssssssss 😔 help find out pitch.........
@Tkelly • 06 Jun, 2009 There is formula for calculating the pitch, but it also requires the technical data as written earlier.

first u need to know the load,to choose the module type.ie.module1,1.5 etc.higher the module more distance u will travel for one rotation of pinion.and lower the resolution will be.
you need to have the gears technical handbook to choose the appropriate rack and pinon.give me some time i will post the gear reference manual.using which u can do the module and pitch calculations.
@Tkelly • 12 Jun, 2009 Zorif is right. I also suggested same thing.
From the load you can decide module od DP ( in inches). Once you know the module, you can calculate further data from gear design handbook.

tnx..for this info..hope it will be completed soon.,Im gonna subscribe to this thread cause I really need a solution for my rack and pinion and other mercedes parts..😒
@satanas • 03 Nov, 2009 hi, i would like some information about " how to mount a rack and pinion in the vertical plane".. the pinion will be moving the rack, which will follow a reciprocating vertical motion.. the load is aprroximately 3 kg.. any recommendation on wat type of rack should i use?

thx beforehand..

@madhukar0028 • 02 Sep, 2010 hi.......can someone tel me how to calculate rpm of pinion in rack pinion mechanism.........
thanx
@Soham De • 03 Nov, 2014 Dear Sirs i want to know the standard rack and pinion gear dimensions for the steering . where cn i get that I hv my load details!!!

@entrepreneur • 23 Dec, 2015 i need 1:2 steering ratio can u plz hlp me?????
@Anjudivi • 04 Mar, 2016 Hii . Actually i want to knoe the formula for 1/16th distance travelled on the work piece which has rack and pinion movement . Can u plz help me out
@Anjudivi • 04 Mar, 2016 Plzzzz plzzz ans me fast
@Kalaiyarasan Rajendran • 04 Mar, 2016 www.atlantadrives.com/pdf/ads_racksel.pdf
check out the link.!
@Anjudivi • 04 Mar, 2016 Actually wanted to knoe the distance travelled not the load which is kept
@Anjudivi • 04 Mar, 2016 Thnks 4 try 2 help me out but the link which u sent me does not contain the info which i want
@Kalaiyarasan Rajendran • 05 Mar, 2016 oops.!! sry 2 hve👎
