Well I always like books from RS Khurmi, TOM by RS khurmi pdf is also one of the good book from same author.Machine Design by RS Khurmi contains 32 chapters and total 1251 pages.Mechanical Subjects like Machine Design and Industrial Drafting, Machnie Design -1, Machine Design -2 and Dynamics of Mechanics.I am in TY of Diploma in this book there is all points which i will need in my next study.
Design Of Helical Gear Pdf Is AlsoNordiana et. al.,(2007) study computer aided design f or a spur gear called Cadgear( 2007),an interactiv e computer graphics able to generate accurate data and p roduce precise and efficient 2D desig n drawings based on strength and wear calculations. Design Of Helical Gear Free Of NoiseA designer of a modern gear drive system must remember that the main objectives of a gear drive is to transmit higher power with comparatively smaller overall dimensions of the driving system which can be constructed with minimum possible manufacturing cost, runs reasonably free of noise and vibrations and which requires little maintenance. Design Of Helical Gear Software HelOSpur2011 WasAs a result, an interactive user friendly low cost software HelOSpur2011 was developed to relieve designer of analytical way of calculating needed parameters for design of helical and spur gears, generating reliable data for use in manufacturing process. The software is able to produce accurate and efficient 2D (two dimensional) and 3D (three dimensional) detail working drawings as a result of interactive computer graphics and provide substantial saving in time and cost of production. Relative accuracy of the software stand at 99.6.The work has demonstrated the effectiveness of using the software to cater for helical gear design problems as well as spur gears when helix angle is zero. The introduction of this software to the society will in no small way increase productivity and reliability of helical and spur gears design.

A d esigner of a modern gear drive sy stem must r emember th at the main o bjectives of a gear d rive is to transmit higher po wer with comparativ ely smaller overall dim ensions of the driv ing system which c an be constructed with minimum po ssible manufacturing cost, runs reasonably f ree of nois e and vibrati ons and whic h requires little maint enance. As a result, an i nteractive u ser friend ly low cost software He lOSpur201 1 was deve loped to r elieve desig ner of an alytical way of calcula ting needed parameters for desig n of helical and spur gears, generating reliable data for use in manufacturing process. The sof tware is able t o produce accu rate and efficient 2D (two d imensional) and 3D (three dimension al) detail working drawings as a r esult of interactiv e computer graphi c s and provide substantial saving in time and cost of production. Results generated by the soft ware shows that the computed face width (for strength c heck) and wear check for he lical gears design as against m anual meth ods were i n relative error of 0.64 and 0.35 respectively. Relative accuracy of the sof tware stand at 99.6.The work has demons trated the effectiveness of using the softwar e to cater for helic al gear d esign prob lems as we ll as spur gears whe n helix ang le is zer o. The in troduction of th is software to the society will in no sm all way increase productivity and reliabi lity of helical and spur gears design. Keywords: Helical gear, interactive, efficient, reliability 1. The CAD system allows design modifications to be performed easily and efficiently. The use of computers and the develop ment of computer aided design techn iques have resulted in significant reductions in design project costs, working hours, incons istencies and mistakes (Ra y, 1987).The introduction of CAD to engineering design has yielded economic benefits. Farag ( 1987) reported that the work of 32 dr aftsmen working without a C AD system may be done by 8 draftsmen with th e use of computer aided. Jain (2001) defined the term gear system as a power transmission element commonly used to transmit p ower or rotary motion from one shaft to another. Maitra (2005) st ated that the designed gear must be able to tran smit high power with little or less noise and vi bration.The determination of t he proper gears to use in a p articular application is a co mplex problem because of many factors involved. Singh, (1997) highlighted some of the factors in t he design of gears such as: the gear must operate together without tooth interfer ence with a poor length of contact, the gear teeth must have t he ability to transmit applied load wi thout failure and wearing quali ties of the teeth must b e considered. These theories usually give rise to a set o f equations which has to be solv ed to arrive at a satisfact ory result. Venkatesh, kamala and Prasad (2010) work on Design, Modeling an d Manufacturing of helical gear for m arine engine. The CATIA software was dev eloped to study the structural analysis on a hi gh speed helical gear used in marine engine. This work was carried out to establish stresses generated and deflectio n of the tooth for the differen t materials. This work cam e out with the findings of m aterials best suited for the marine engine.
