Hi Guys,
so ive had alot of people asking about why when the drag is maxed out on a lever drag reel does the reel start to feel heavy and everything stiffens up on the reel, otherwise know as "Binding"
I know this is technical but i think it will help alot of guys who are looking at lever drag reels and will help them choose the right reel for the line class they want
This has been written for Avet reels, but will apply to alot of the Lever Drag reels on the market.
The term "binding" is a bit misleading..there is no contact with moving parts or rubbing when this happens. What you are feeling when very heavy drag pressure is applied is added drag from lateral load on a radial bearing. It is not the pinion gear bearing that you feel, its the outside spool bearing. When the Drag lever is applied, the cam pulls a drawbar that goes through the pinion gear bearing, the pinion gear, the drag plate, the spool, to the outside spool bearing. This compresses the spool to the dragplate. When the drag and spool are compressed the load is equally distributed between the pinion gear bearing and the outside spool bearing. The pinion gear bearing is housed in the drive-side plate and is much larger than the spool bearings, and capable of taking much higher side loads. The outside spool bearing is much smaller.
The outside spool bearing was intentionally engineered smaller than the pinion bearing to reduce rotational mass of the spool and reduce the rotational drag of a larger bearing to make a lighter better casting spool. The smaller diameter spool bearing also allows a smaller diameter spool hub for it to fit into, creating much more line capacity for an overall smaller, lighter spool.
It would have been much easier to use the same outside spool bearing as the pinion bearing...fewer parts to stock, simpler engineering and machining, as all the bores would be the same...etc..but the reel wouldnt cast anywhere near as well..and the overall size of the reel would have to be significantly larger and heavier to get the same line capacities. For a great casting, small light leverdrag its a great design, and using a reel within the limits it was designed for its a small trade-off to have it all.
With the Avet Raptor reels, the lateral load issue is eliminated using a different drag compression configuration...keeping similar bearings and spool/reel dimentions.
