carburised steels
gears are used to transmit power and motion
Planetary gears can be spur or helical gears.
The suitable materials for gears include steel, which offers high strength and durability, and is often used for heavy-load applications. For lighter applications, aluminum is favored for its lightweight and good machinability. Additionally, plastics such as nylon and acetal can be used for gears in low-load and low-speed environments, providing noise reduction and corrosion resistance. The choice of material ultimately depends on the specific requirements of the application, including load, speed, and environmental conditions.
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.
