Gear Design | Spur Gears

[@Lesics]

You can find out derive radii of gears by considering speed ratio and space constrains. If gear 1 is lifting the mass, Torque required , T1 = R1xMxg

I always knew engineering was technical, but I never thought something that looks so very simple had such a paramount science behind it...

[@CockatooDude]

Yeah it's crazy how much knowledge is behind everyday objects.

[@rock3tcatU233]

This is nothing, you should read the theory which has been developed for simple flexure beams... I have a number of 1000+ page books on that stuff alone.

[@drunkdonutboy]

@@rock3tcatU233 yep. I graduated with a mechanical engineering degree, the amount of calculations for the most inane things is overwhelming and there's still more material published on other subjects every bit as lengthy

[@asid61]

Sorry for all the racist comments. The speech is clear and easy to understand for me, and I especailly liked the parts about calculating the allowable parameters using the Lewis formula.

[@shivarudranavi297]

watch again "DESIGN FOR SURFACE RESISTANCE" check its spelling in presentation........

very well presented and coverage of surface stress and load stress very good coverage. Thank you!!

Hey your videos have very good quality. I want to see more videos about machine elements(shaft, belt, chain, bearing). It would help engineering students and others who interested in these.

[@nuchbutter]

I loved it! Just subscribed, and it has already proved invaluable to my new design, prototype and fabrication service. We just incorporated a couple of weeks ago; I'm using Solidworks to design prototype parts, which we print up on our Formlabs SLA 3d printer. All the passion and creativity will get us nowhere without fundamentals, and you have so generously and succinctly provided tools for our foundation! Shukriya, CDR Krotchety USN

[@warlock1ful]

So apparently we have to assume t1 and then check it with the interference equation. Whats the best way t1 without just throwing out a random number?

[@anilaxsus6376]

i dont think there is any, its up to your desired design constraints

[@johnswimcat]

Very clear, to me anyway, and I'm as English as they come (as you can see from my childhood photo on the Norfolk Broads!). Great video

[@fwsilverstone]

Is the diameter of the two gears at 1:45 the diameter of the root circle, pitch circle, or tip circle? I assume pitch circle since they intersect at a single point but it is unclear in the video because if it is the pitch circle then Dp1 + Dp2 does not equal allowable width. To find the allowable width, you would also have to add the addendum of each gear (assuming the diameters are of the pitch circle). If you don't do this, the teeth will stick out slightly further than predicted with the equation, therefore improperly calculating the space that the gears will take up.

if using "diametral pitch" automatically means that u are design this gear in "inch" unit right ? Or else u will use "module" if u are working in "milimeter" .... i have some doubt bout it...

[@nikhilreddy3638]

In the lewis bending equation ,why the bending stress is not depending on the material we use?

[@aswinrajeevan3674]

The critical value of the stress is dependent on the material you use and this has to be greater than the stress generated as calculated from Lewis Bending Equation

so it means that whatever torque is generated by the output gear, the same torque is transmitted by the shaft on which the output gear is mounted......

Sir can you tell me " why in design of gear pair, difference in brinell hardness number of pinion and gear is kept 30

[@gamingSlasher]

The thinking is that the pinion should be a little harder because it has more revolutions and therefore should be a little stronger. The harder tooth will also wear on the softer tooth and you then want that wear on the gear.

When does social and cultural considerations such as pride in regional identity and subsequent non-standard accent become unacceptable? When it can be determined that it is being applied as impedance to conveyance of information, that would be linked to pace of transference and conversion of more physical commodities - like labor into goods and service, or practice into experience. If resources including time, space and raw materials need to be paced and regulated in its conversions and depletion, humans should be permitted to work on other facets of being human in the interim (is this why it's called the "mean time"?), versus inventing techniques to generate resistance and abrasive forces in the social and cultural realms in such deceptive ways. Especially when such forces have been known to get out of hand, leading to outright destruction and, not just collateral damage, but trauma on a psycho-dynamic level, that may take far longer to stabilize or regenerate
