cogged belts

Do cogged belts serve any special purpose are can they be replaced by normal ones ex/ ax45 to a45, stupid question maybe but, I have new maintenance, some units have cogged belts others not and they are same models of units.

Some guys say that X belts grip better, but I feel they tend to slip more due to less surface contact with the sheaves. They have a higher HP rating and don't crack as bad when used on a small dia. sheave.

In a nutshell:
Cogged belts have slots that run perpendicular to the belt’s length. The slots reduce the bending resistance of the belt. Cogged belts can be used with the same pulleys as equivalently rated V-belts. They run cooler, last longer, and have an efficiency that is about 2% higher than that of standard V-belts.

Alignment tolerance is less for a notched belt other than that they are a better belt.

They are actually better on smaller sheaves..They contact more of the sheave surface. (Less slipage).

Ive never been one to buy any of the 1 size fits all parts that have been on the market for years such as rescue capacitors and motors and such, not saying I havnt used some with sucess but was wondering if anyone has used the adjustable or build your own v-belts? I was wondering if they really work and do you leave them permanent? It looks like to me its got less surface area to grip. I guess youall know a belt grips on the sides not the bottom, and they look like theres not much for the pully to grab so I would think they would be temporary. Any experiance with them?

I use these as a temporary replacement if I happen to run out of a certain belt and this particular piece of equipment needs to be up and running NOW. Then it will be replaced as soon as i get the new belt.

On another note, another tech once told me that he had seen one come in from the factory on a piece of food equipment. Cant remember the manufacturer (maybe hobart?)

Havent used them...And havent heard anything good about them. most people I'v talked to about them said they dont last long.
I guess they would be ok temporally until you get the right one.

browning has an app for smart phone ,belt efficiency calculator,for regular belt vs cogged belt

I prefer the ax belts. They last longer, don't stretch as much as "a" belts, but they wear out pulleys faster.

That was this link

Carrier does not use them. They claim they wear out pulleys faster. On jobs I have cogged belts, I'm replacing pulleys and sheaves every 2 years. Thats with a 32nd to a 16th groove worn into the pulleys

I've seen these belts:

used on heat wheels on ERU's.
