Drag on conventional reels How can spool turn when pinion is connected to drive?

[thedw]

Hi guys!

sorry if this is a noob question! never owned a conventional level drag reel b4

Since the 'pinion gear' is on the spool, and that is connected to the drive gear, how can the spool turn when line  is being pulled out?

wont the drive gear turn as well???

[Nuvole]

The drive gear are stop by either the AR beaings or dogs.

[alantani]

the pinion gear locks into the shoulders of the spool shaft, or a crosspin through the spool shaft.  but the pinion is bevelled on one side and the pinion will briefly disengage and chatter as the spool spins. 

[thedw]

so the pinion gear on the spool will sort of disengage when the fish pulls out line?

[alantani]

no, only when the spool is spinning in the "retrieve" direction.  when a fish is pulling, the pinion gear is locked in tight.

ohh hahaha got it alan!! thks!!


for low profile reels, since the drag disc are located within the drive gear, the pinion actually turns with the spool and drive gear!

The ones w/o the cast release works differently from the ones with it.

For star drag type conventional reels:
When the reel is engaged (Pinion engaged w/Main) via the eccentric/jack/yoke assembly... the main gear sleeve and the handle to which it is attached are held in place by the dog(s) (or opposing force applied to the handle.  The drag stack which rides inside the main gear creates friction between the main gear and the gear sleeve which allows the pinion (engaged to both the spool, and the main gear, when spool travels in the correct direction) to travel when the static friction forces at a given setting are overcome.  

The basic concept is the same for lever reels, though the mechanics can differ depending on the drag assembly.  The pinion is typically part of or attached to the spool shaft which via a given drag mechanism will creat friction against the spool itself.  The handle is attached directly to the drive gear assembly, which utilizes either dog(s) a one-way bearing, both, or some other mechanism to resist reverse (anticlockwise) movement of tye drive gear, and a cam thrust assembly is attached to the lever which along with spring washers causes the pinion gear/spool shaft/drag and spool assemblies to move laterally and engage the drag assembly or marry the spool to the pinion/shaft via the drag and pressure discs.  The frictional forces generated allow the spool to resist clockwise rotation against the dog/Antireverse mech or handle force applied.  The pinion and main gear stay engaged throughout, and typically drag ranges can be adjusted (by moving the lever) when the reel is under load, but applying force against the handle or reeling under pressure, can introduce lateral forces on the main drive gear and shaft...and increasing drag pressures can apply increased lateral loads on the affected parts (I.e. pinion bearing, left plate bearing or other parts depending on the design.  Another typical advantage of the lever drag reel design is that the drag surfaces are usually larger, fewer, and consequently smoother overall.  There are many other factors at work though.  Take a look at some reel schematics of each type and some of the other posts of the forum and it should be able to make sense.  

Hope that helped?

haha wow!

thks!

Yes, the main gear turns on the gear sleeve when line is puled out under drag and the pinion is engaged with the main gear.

Yes, John (Tightlines) is a wealth of knowledge! You have to pay attention. He uses some big words.
