Gears or cogwheels are used in various machinery to transmit power and motion between different components. They are commonly found in applications such as automotive engines, bicycles, industrial machinery, and clocks. By altering the gear ratio, they can increase torque or speed, making them essential in both simple devices and complex systems. Additionally, gears play a critical role in ensuring precise movement and synchronization in mechanical assemblies.
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.

Planetary gears can be spur or helical gears.
mostly helical gears !1.
There are three main types of gear combinations used in mechanical systems: spur gears, helical gears, and bevel gears. Spur gears have straight teeth and are used for simple applications. Helical gears have angled teeth for smoother operation and higher loads. Bevel gears have cone-shaped teeth and are used to change the direction of rotation.
Gears are used to make pieces of items or objects rotate. They are used in a majority of machines available.
Bevel gears can be used to change the direction of drive in a gear system by 90 degrees
It has 6 gears i know this because i used to have one
Gears on a bike are used to help the rider adjust the resistance and speed of pedaling. By shifting gears, the rider can make it easier to pedal uphill or go faster on flat terrain.
The most common types of bevel gears used in rear axles are straight bevel gears, spiral bevel gears, and hypoid gears. Among these, hypoid gears are the most widely used due to their ability to provide smoother operation, higher load capacity, and better efficiency compared to the others. Spiral bevel gears also offer advantages in terms of load distribution and reduced noise but are less common than hypoid gears in automotive applications. Straight bevel gears are typically used in simpler, lower-speed applications.
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.
