A gear drive uses gears to drive the camshaft vs a belt or timing chain. Some bikes use a shaft drive vs a chain that is often confused with a gear dive.
I'm sure it is possible with a bunch of work, but why would you want to? A chain drive is heavier, requires more maintenance, will not last as long and is safer. Chain drive requires rear wheel adjustment every 300 to 3000 miles (depending on the model), lubrication with special chain grease (do NOT use WD-40 or 3-in-1), and if a chain comes off the sprocket, you are facing a rear-wheel lockup which can cause a crash at speed. Belt drive requires no lube, no performance loss vs chain, and if you throw a belt it will become shredded which avoids a nasty rear-wheel lock.
There are a number of factors that would affect the answer to this question including torque, shaft speeds, load etc. This is why there are many methods of delivering force to remote locations (worm, belt, chain). I believe some of the advantages when working with belts are - reduced friction losses as the belt has more contact area - decreased energy loss through vibration (in effect a belt has vibration dampening) - belt breakage usually seperates the drive system causing little damge or danger unlike chain If someone can answer the physics side of this I would be most appreciative as most of these answers come from car knowlege (see variable belt drive vs. timing chain).
chain; most late model hondas now use chains vs belts
I just changed my drive belt on my Cub SLT 1550...first, you must remove mower deck, then crawl under tractor and remove bolt that holds the mower belt pulley and the centrifugal clutch (you will need to use something to hold the shaft so it doesn't spin when you try to loosen the bolt from the shaft). Once you get this far, you can lower the mower belt pulley & the cetrifugal clutch & finally the drive belt pulley. Now you can remove the drive belt. Install new drive belt & make sure you put all parts back the way they were removed...it does take some work, but you can save about $200 doing it yourself VS dealer.
I'll Quote for you the directions given by the Gregory's Manual (No 268 for Commodore Lexen V6 1995 - 1997)Drive Belt:The Drive Belt tension is controlled by a tensioner assembly which maintains the correct tension on the drive belt and compensates for wear and stretch.The tensioner assembly is equipped with a tension indicator that shows when the tensioner is exerting minimum pressure on the drive belt.Check the drive belt for cracks or separation between the rubber and the fibre belt by examining the portion of the belt that is positioned around the water pump pulley.Note: If the drive belt is slipping and the tension indicator is within the normal operating range, remove the drive belt and check that the pulleys operated by the drive belt including the tensioner pully ratate smoothly without binding. If no fault can be found, renew the drive belt tensioner as described in the Engine section.To Renew(1) Place a 15mm ring spanner on the drive belt tensioner pulley bolt and rotate the pulley assembly anti-clockwise away from the belt BOLT IS LEFT HAND THREAD!(2) Hold the pully in this position and remove the drive belt from the water pump pulley. Return the pully to its previous position.(3) Disconnect the drive belt from the engine pulleys and remove the drive beltInstallation is a reversal of the removal with attention to the following points:(1)When installing the drive belt ensure that the grooves in the drive and engine pulleys alighn.(2)Rotate the tensioner pulley and position the drive belt onto the water pump pulley.(3)Start the engine and check the drive belt and tensioner operation.NOTE: It is normal for the drive belt to emit a squeak when the engine is started or stopped.SEE GREGORYS MANUAL ENGINE TUNE UP SECTION PAGE 26 FOR DRIVE BELT INSTALLATION SCHEMATIC.SCHEMATIC IS ALSO IN THE OWNERS MANUAL FOR YOUR CARIT IS VERY IMPORTANT TO REFER TO THIS DIAGRAM UPON INSTALLATION FOR BELT DIRECTION
Most timing belt (vs timing chain) cars need service at 60,000 miles. If the belt fails, and your engine is the interference type, the valves will be hit by the pistons, ruining a good engine.
"Shaft effect" is the drop in the back of a shaft drive motorcycle under acceleration, they also pop up when you stop accelerating which can cause a loss of control in a corner That is why some sport bikes don't use them. BMW paralever-frame motorcycles use a shaft drive; the paralever shaft drive design reduces or eliminates this effect.The shaft effect must be understood to increase control in cornering. By increasing the throttle in a right-hand turn and decreasing the throttle in a left-hand turn shaft effect can work for the rider to increase control. It's all in understanding the limitations of your machine.AnswerThe shaft drive is heavier than the belt drive, has more frictional losses and id more expensive to repair. The belt is more prone to damage from road debris than shaft or even chain. It is also critical that the belt is taught at all positions of the swingarm, something chain is much less sensitive to and shaft does not have. The shaft is more durable and requires little or no maintenance. All run quietly and smoothly when in proper working order, with belt and shaft having a slight advantage over chain.. AnswerThe main disadvantages of shaft drive are weight, cost and a certain loss of horsepower due to friction. They are costly to repair, but that will hardly ever be necessary. The main advantages are smoothness, absence of oil spill, ease of maintenance and reliability. A shaft drive will normally never require a roadside repair, and an oil change each time you change rear wheel will normally be all you need to do about it. Hence, shaft drive is preferable for touring. A more sporting motorcycle will normally have chain drive due to the low weight and ability to easily change transmission ratios by using different size sprockets and partly because of looks. Chain drive is obligatory in most forms of racing. But chains may break and they need frequent attention, maintenance (lubrication) and adjustment. HistoryBMW introduced shaft drive in motorcycles in 1923. This was in response to the fact that at the time, drive belts were made of flaps of leather riveted together. Compared to the level of maintenance required by leather drive belts, a shaft drive seemed to be the final solution. With the advent of chain drive, the low maintenance advantage of shaft drive diminished slightly, but not altogether. Shaft drives may require maintenance between 40,000 and 150,000 miles. Compared with a 8,000-12,000 replacement schedule for chain drives, it is evident that shaft drive still holds a maintenance advantage.Chain/belt drive DOES have an advantage over shaft drive, however. A shaft drive has a mechanical efficiency of around 80%. This means only 80% of the input power is transferred to the rear wheel. The efficiency of a chain/belt is mid 90%. The chain loses efficiency only due to friction internal to the chain and can be helped somewhat by frequent lubrication of the chain, but this increases maintenance effort and time.
In Smackdown vs Raw 2008, You can make any Belt
no
if your a black belt VS HIM AND WIN
you have to vs sensei and get the black belt and win
