That's easy -- if the top gear reduces rpm, that would reduce engine wear, noise and gas consumption. Maybe the other person is smart and says, let's just put in a lower final ratio. The problem there is that many modern cars don't have optional final ratios.

Dual clutch's generally provide more speed and better economy. I would presume the same could be said for a straight cut or dog box since they're more efficient than a normal manual. So not only will it save you money in fuel but it wil also mean you can get places faster which allows more time to spend with the family/better half. Hows that?

Have to point out a straight cut gear is actually weaker than a helical gear. Its just they dont generate axial load which forces to 2 gears aparts and causes teeth to get munched off.
@deveusdude6 жыл бұрын
LandRoverLife it's stronger because since 2 teeth are meshing at once instead of 2, more surface area=high load capacity
@SomervilleMetalWorks6 жыл бұрын
Peter Donaldson mate you might want to check your facts if size is equal helical gears are stronger because they are longer contact patch because theyre angled. Most straight cut gears replacing helical take up less room therefore can be made larger in same space. Its not to say they're stronger only that bigger teeth are stronger than smaller teeth. Once again my point is that its the axial load that causes helical gears to fail not that they are weaker
@NBSV16 жыл бұрын
The helical gears also have higher parasitic power loss because of the sliding in and out of mesh.
@gordowg1wg1456 жыл бұрын
Swings and roundabouts... For the same tooth count, a helical gear is thinner in the loaded direction - approximately 90 degrees to the tooth face helix. A helical gear is point loaded, with a sliding action, whereas a spur/straight cut gear is loaded across the full width of the gear - so it has a higher stress on a smaller load bearing part of the tooth - you can verify that with a simple vector diagram. A helical gear has a higher axial force on the end thrust faces/bearings, which increases with the helix angle, and 'may' increase case loading and distortion. Despite the common misconception (even seen here) there is still a single tooth contact for most of the rotation of the gears, except the very small period when the load is transferred from one pair/set to the next. Where a helical gearbox has a big advantage is in reducing the backlash/chatter/shunting as torque is transferred more smoothly between the loaded teeth as the shafts rotate, which means they are much, much quieter - spur gears can be made relatively quiet ( I have known an instance where it sounded just like any normal helical type - but that was a single example), but the tooth design and manufacturing is expensive as the tolerances and design has to be right.

Robert D Way back in the day, I swapped a 5 speed close ratio in place of a 4 speed in a diesel rabbit. Those things are soooo slow, rated 52hp. Dropped like 5 seconds off the 0-60, felt like a comparison of it picking up 15-20hp. Way over on the other hand, I put a close ratio behind a late model diesel and while it would rip trees out, a buddies stock model was quicker.

Helical gears are always stronger compared to same straight cut gear but generate a side thrust. This is why herringbone gears are used where high loads and tooth velocities are high. Helical gears have a huge advantage is one important area. By changing the helix angle you can produce a mathematically perfect gear. Pitch circles that are thru the middle of teeth instead of on the outer portions. Not having to compramise this aspect is important when many ratios must share the same shaft centres. No point in having an expensive transmission if it has a compromised gear pair.

Very cool, think gear ratios is much simpler then people make it out. You basically want, the most granular gear ratios that means more gears as possible, but add's weight as literally more gears jamming into transmission. So like you said, you really don't have to worry about lower ratios cause your not in them ever on race track (except quarter mile). So by making the lower gear very long, you can be more granular on the top end, and that means you have more phases where you can be in the power band or torque band of the engine, and be faster.
@kevinburke67433 жыл бұрын
I would have thought a Helical Gear of the same face width/thickness as a Spur Gear would be much stronger in terms of load carrying capacity & life. A Spur gear of say 1" thickness has a contact ratio of 1.1(teeth engagement.) Gears are always in pairs or more in a train. The smallest gear goes the fastest by definition. So wears quicker, also the teeth are weaker if not corrected as they are further from infinite(Basic Rack Form.) Now let's look at the same gear but give it a 30degree pitch helix angle. The SIN of 30degrees is 0.5. Therefore the effective face width along the line of action(normal to the helix angle is 1.1/2". Or 50 % more. Now let's look at engagement. You have a rolling continuous helical overlap plus a higher contact ratio. This has to result in a better stronger more reliable gear set. The load sharing of the helical overlap & higher contact ratio must win out every time?
@gogogeedus Жыл бұрын
The down side to a helical gear is side thrust which wear parts out, and must be considered as part of the equation, wouldn't you say? but I guess they have very adequate thrust washer designs these days.
@griplimit2616 жыл бұрын
I agree with everything you said but one thing, helical cut gears are generally stronger than strait cut due to the fact that there is more surface area of the teeth in contact with one another at any given moment. Strait cut gears are used a lot in racing applications because they are more efficient with less friction because there is less surface contact between gears.

There is something important you could have covered with your straight vs helical cut gears. Helical cut gears have a sideways thrust that straight cut gears do not have. Most helical cut transmission use taper bearings to transmit this thrust to the case, a straight cut transmission can use roller bearings instead and that reduces the size and weight of the case.

I was looking for a sequential shifted, dog engaged, helical gear transmission that is rated for 900-1000 hp and had enough gear spread to allow 4.11 rear ratio and not have huge revs at highway speed. Think pro touring. I can find 3 out of 4.
