Stable and unstable configuration of double helical gear

Click For Summary
The discussion focuses on the stable and unstable configurations of double helical gears, highlighting that stability is achieved when the cave of one gear's "V" tooth drives the arrow of the other, while instability occurs when the opposite happens. The question raised concerns whether to realign the driving gear or the pinion, noting that while one may realign in a stable configuration, the other could misalign further. The concept of net force or thrust is debated, with clarification sought on whether it refers to the forces acting on each gear or internal forces. The interaction between the gears is emphasized, as one being pushed in one direction affects the alignment of the other. Overall, the complexities of gear alignment and the forces at play in both stable and unstable configurations are central to the discussion.

Hi :

according to :https://en.wikipedia.org/wiki/Gear#Helicalthe stable configuration is when the cave in one of the gear's "V" teeth drives the arrow of the other "V".where unstable configuration is when the arrow part of V drives the cave of the other Vso assuming the direction of motion is up

unstable : ^ stable V (how the teeth in contact looks like from above)
my question is : do we want to re allign the driving gear or the pinion? because while the driving gear may re-allign itself in the stable configuraiton, the pinion would tend to crock more to the other direction. and vice versa with unstable configuration.on the wikipage when they say netforce/thrust, I am assuming that are talking about the net force/thrust on each of the gears (or else that would be an internal force)

while one gear is pushed to the left, the other is pushed to the right, which means while one gear is being alligned back into it's desired position, the other is being misallign even more.

oh or maybe they are referring to the other type of axial misalignment?
 
Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
