1 Gear Design Tools & Presented by : Mr. R. N. Madke Date :

2 Gear Design Tools The Gear Design Tools normally we use today are The software for sizing of gears, their geometry and rating as per different standards. Software for Shafting and Bearing - Sizing & Selection. Micro-geometry & Contact Analysis. Software for 3D Modelling and 2D drafting. Software for Structural Analysis. Bearing and torsional analysis. 2

3 Gear Design Tools There are many software for Gear Calculations which have come in the Market. But we have preferred KissSoft and KissSys. Reasons : - User friendly - Interactive - Suggests solutions - Decision making on optimum sizing is faster - Covers almost all international standards - Almost all types of gear applications can be solved 3

4 Gear Design Tools In good old days when I started my career in 1973 the available tools for calculations for gear rating and gear geometry were - Logarithmic Tables - Slide Rules In late 70s or early 80s the scientific calculators came into the market. In late 70s we used to write the computer program for gear rating and geometry calculations in FORTRAN language. But the availability of computer was a problem. 4

5 Gear Design Tools Scientific Calculators had made our life some what easier. The PC came into the market in early 90s and subsequent to that we have seen a revolutionary change in computing system as well as in Industry. Programming languages also changed & life started becoming easier and simpler. KissSoft came into the market in early I know KissSoft scince the time it was launched into the market. 5

6 Gear Design Tools Initially the rating calculations were limited to DIN 3990 and the geometry was as per MAAG method of calculations. Many features got added over a period of time as a part of up-gradation based on the suggestions and requirements of customers. Customer satisfaction has brought them to this leading position today. On behalf of KissSoft & KissSys users, I Thank Dr. Kissling for developing a software which made your customers happy. 6

7 Gear Design Tools Introduction of any software in a industry requires training and re-training of the people for : - Understanding the features & using them effectively. - Understanding the new upgrades. - Thanks to Mr. Hanspeter Dinner & Mr. Raman Gupta who always take interest in introducing the new features and upgrades to the users from time to time. 7

8 The Top Management always looks for return on investment and a pay back period. It is always the responsibility of R & D Chief OR The Design Head to convince Top Management on investment in software. Following points are important : - What is the present method of design & What change the software will bring in. - Increase in output because of the change. - Reduction in material cost due to optimization in sizing and change of material. - How can your product be with the present trend in the market. 8

9 - The changes in the International Standards are always available in the next or next to next upgrades of the software. - To take the benefits of these advantages one has to have the AMC. - Get yourself convinced before you convince anybody. - No management will say NO if you put up the case with proper justification. 9

10 Whenever any new engineer joins engineering dept. or R & D, he should be trained in a proper way. I have few suggestions to the Design Incharges : - Do not be in a hurry to give him software for calculations for gears. - Give him an induction programme in Gear Manufacturing. Let him go through the total gear manufacturing process and understand the same. - Let him study the gear quality and study how to ensure the same. - Now start his training in Gear Design with Study of 10

38 On understanding of all this the new engineer will know what really the gear design is. Now let him workout with manual calculations the geometry and rating of gears as per any standard. This will make him to understand what is happening at the back side of the software. Let him prepare the cross sectional and detail drawings for few sets of gearboxes. Now the engineer is ready for use of software because now he is ready to have interaction with the software. Train him for using the software. This the way I feel you can produce a good gear engineer. Follow this and give me a feed back. 38
