What is the difference between syncromesh and constant mesh gearboxes?

In a synchromesh gearbox, synchronizers are used to match the speed of gears before engaging, resulting in smoother and quieter gear shifts. Constant mesh gearboxes have gears that are always in mesh, with dog clutches used to engage gears for selection, which can be quicker but may be noisier.


What is difference between synchromesh and sliding mesh gearbox?

Sliding mesh - This is where the gears are not in constant mesh with each other and the gears on the main shaft slide over to mesh with the gears on the lay shaft/counter shaft. Synchromesh - the problem with constant mesh is that the gears crash into each other when changing gear because there travelling at different rpms (one at engine speed and the other a lot slower) They dont line up properly when spinning and when they go to mesh they end up grinding. So the awnser is Synchromesh which uses Baulk rings to lock onto the gear first before the sliding sleeve comes over to lock on. Difficult to explain how it works but basically its a smooth gear change.

Where are sliding gears used?

Sliding Gears in a transmission are straight-tooth spur gears with a taper (also known as a lead) to make engaging easier. Helical gears are mostly used in a transmission because spur gears produce gear noise and have a great strain on the teeth of the gear since only one tooth can be in contact at any given time. But because helical gears cannot be taken out of mesh, spur gears are used for the reverse gear because reverse spins the opposite way and cannot be in constant mesh.


Why reverse gear is spur?

Reverse gear is spur because it has to slide, sliding mesh gearbox uses spur gears. Because if it was constant mesh gear (helical) it could not slide in and out, therefore it could not go in the opposite direction of rotation.


Do the gears of a bicycle mesh together?

Don't really know what you're tinking of with "mesh together"... On a bike with external gears the gears will not mesh. There's the chain acting as a go-between to transfer the energy. On an internally geared bike you will have cogwheels that are interlocking and driving each other.
