Classifications of Gear Drives
Gear drive is a precision component. According to gears' different working principles and applications, gear drivers can also be divided into various types. It can achieve the intended function relying on many aspects such as solid design, precise assembly, and high-quality components and so on.
There are various gear drives. Now let see them specifically. The first category is the electric drive. It is an industrial system that can transform the electrical energy to mechanical energy. This drive system is not complicated. It makes use of electrical components to achieve its performance. Although it is very simple, it can still be used in many places such as home appliances, air compressors, music or image players, robots, etc. Besides, it can also be used in transportations like boats. This kind of system has many advantages. For instance, it can contain the control of wheel slip and slide which can lead to reducing the tire wears.
The second category is the mechanical drive. Generally, it is used to provide a variable output speed from a constant speed power source or to provide torque increase for a variable speed power source as in an automobile. This category can be future divided into geared transmission, belt drives, chain drives and so on. As to the chain drives, they can provide infinitely variable speeds. The mechanical drives also have many advantages. When compared to the electrical drives, they are less costly. Moreover, their control is much simpler. They also have a wide range of applications such as the heavy industries, mining, and even aerospace, etc. It is also very common that they carry a lot of disadvantages. For example, they can not transmit as much power as the first category. Besides, they are not durable enough.
The third category is the hydraulic drive. It is also called the fluid drive. When the driving motor is operating at a constant speed, they are used to hydraulically change the speed of the driven load. This category can also be further divided into three basic types, i.e. individual hydraulic drive, central hydraulic drive, direct drive hydraulic drive. Like other types of gear drivers, they can also be used in various places. For example, they can be applied in drilling, anchor winches, deck machinery, and trawl winches, etc.
Addition to the above types, there are still other classification of gear drives such as the hydrostatic drives and speed changers. These two are also quite important in our industries. They have very wide range of applications, too. All in all, different gear drive classifications can perform differently to meet various requirements.

Is it bad to change between the Drive gear and Neutral gear while driving?
I have a Hyundai Elantra with automatic transmission.
Jeremy, the other folks are full of you know what. If one is going to answer a question, they need to know the answer. No, shifting from drive to neutral or neutral to drive while in motion won't hurt a thing. The only way you could do any damage would be to be in neutral, rev the engine way up and put it in drive (or any other gear). You'd get a big jerk and a loud clunk which would stress the drivetrain. If you're coasting in neutral at a slower speed, shift into drive and don't worry. If you're coasting at a higher speed, say 30+ mph, rev the engine up to the speed it would normally be turning before putting it into drive. What IS hard on a transmission is to be stopped in traffic and you set there forever with it in gear and your foot on the brake. This causes the oil in the tranny to get hot.
Put very simply, the automatic transmission works by one fluted device attached to the engine throwing oil onto another fluted device attached to the transmission shaft. When idling, little oil is being thrown onto the transmission side and thus the car wants to creep forward slightly. Rev it up, more oil is thrown and the tranny starts turning. Think of it like a garden hose, squirt a little water against your hand and you barely feel it, turn up the pressure and you feel the energy. When stopped in traffic in drive, the oil it being thrown around and since it can't turn the tranny, the energy of the moving oil is turned into heat. Shifting into neutral lets the oil turn the tranny side but you don't go forward since the transmission gears aren't engaged. Since things can move, no heat is produced by the moving oil.
