I have a stepper motor (this one). Its shaft is of type "oval" or whatever, so like a circle but with 2 flat sides.

I have a stepper motor (this one). Its shaft is of type "oval" or whatever, so like a circle but with 2 flat sides.
2) Am I even choosing the right things for this task of spinning a rod perpendicular to the shaft's axis? here
1) Is there a standard term, or language, for describing my motor's shaft, as well as the coupler which would connect my shaft to a metal rod? more
What are the benefits of a rigid flange compared to a split flange beside costs? Doesn't the flexible coupler give more friction?
A rigid flange coupling may be a more economic choice if it suits.

That might be overkill in your application (but I don't know).
I'm trying to drive an aluminium plate using a motor via a 20mm-wide 2mm-thick stainless steel tube. The tube is driven by a 6mm motor shaft via a pulley and the torque will be around 5Nm at most. Is it a good idea to attach the plate to the tube with a split collar like this?
However it's not clear what the rated torque and axial force are. If this isn't a good way, what might be an alternative without welding or adhesive?
In last month’s column, I mentioned keys and keyways. Typically, when keys are used with gears, they are accompanied by set screws (also known as grub screws). The tapped holes to accommodate these screws are commonly positioned above the keyslot as shown in Figure 1 and the second at 90 degrees to the keyslot.
Use of a keyless shaft-hub locking mechanism: There are several styles of locking hubs that exist. Their primary purpose is to allow for the repeated repositioning of the gear and also to prevent any damage to the shaft during installation or removal. Thus, they perform the same action of a shrink fit, but they use mechanical means instead of heat. [links]
D id you ever have someone “give you the shaft”? This insult is defined as ignoring or putting someone down. In gearing, giving you the shaft is just the beginning part of constructing your geartrain. Each gear in a system is going to be resting on a shaft as the purchase of each gear is to transmit motion through the shafts of the mechanism. Just as there are many types of gears, there are also many types of methods to attach a gear to a shaft.
Conversely, Fred Couples has a longer, flowing golf swing that looked effortless. But don’t let looks deceive you; both golfers were swinging the golf club very fast (compared to recreational players). here
Getting the right shaft flex is more about what kind of load the golfer applies to the shaft. The shaft itself has no idea how fast you are swinging. It mostly responds to the force you apply. more
I’ve learned by working with one of the best clubfitters in the entire industry that swing speed is not necessarily the most important factor when choosing your shaft flex. Despite that, plenty of “guides” all over the internet will say if your swing speed is “X,” then you should get a specific shaft flex. It’s more complicated than that. Let me explain…
If you have access to a clubfitter or even a teaching professional who has a lot of knowledge about golf clubs, I urge you to use them as a resource first. If you purchase a shaft based only on your swing speed and nothing else, you are just guessing. [links]
Despite having similar swing speeds, each player needed a much different shaft flex. Nick Price couldn’t find a shaft that was stiff enough for him. He applied so much force to the shaft with his swing length and tempo that he needed a much stiffer shaft profile compared to Fred Couples. here
