Gearbox: Know Its Functions and How to Care for It

The speed generated by the motor comes not only from the gas, but also thanks to the role of the gearbox. The function of the gearbox is very important to regulate the speed of the vehicle.


In a gearbox there are various components that will support its performance so that the motor can go at the desired speed. Just imagine if there is no gearbox component in the motor, how can you regulate the speed of the vehicle?


Information about the gearbox and its functions will be discussed in detail here, complete with how to care for it.


What Is a Gearbox in General

The gearbox itself is a component that is needed in the industry or machinery. So in general its use is not limited to motorcycles.


This component has the main function to move the driving force on the machine that you want to move. The two main reasons why a gearbox is important is because it serves to slow down the rotational speed of a motorized dynamo or diesel engine.


The second reason is to strengthen the torque obtained from the diesel or dynamo. So if a machine does not have a gearbox, then the power generated from the diesel engine or electric motor dynamo cannot be controlled.


Besides being used on motorcycles, the gearbox function is also applied to conveyor machines that transport passenger goods at airports. The speed of the conveyor machine can be adjusted through the gearbox so that it can be slowed or accelerated.


The use of gearboxes in general is for machines in factories, fisheries, mining and the most widely felt is to amplify the power of electric motors.



What Are the Functions of the Gearbox on the Motor?

Another term used to refer to the gearbox is Speed ​​Reducer because it can be used to reduce the speed of the power generated. Then how does it function when used on a motorcycle?


The gearbox used in the motor is also referred to as a manual transmission. The existence of this component will create a power transfer system from engine power to other engine parts. In addition, it can also adjust the torque of the rotating motor.


You can see what the detailed description of the gearbox function looks like below.


  • Power Supply in Motorcycle Engine

The main function is to transfer the power or power that has been generated by the engine on another engine so that movement or shift will appear. That way the motorcycle you use can move forward.


The transfer of power from the engine is carried out from the engine room to the wheel which is connected through a chain component. While the automatic motor power will be channeled through the vanbelt so that the two wheels of the motor will rotate.


When you shift gears, the gearbox will work to accelerate or decelerate the vehicle. So the gearbox function here is very vital and cannot be underestimated.


  • Adjusting the Power Generated by the Machine

Reviewing how you add gears or downshift the motor, then the gearbox will adjust the power that is already generated by the engine. That's why each motor has several gears that have different speed levels.


You can adjust the speed by shifting gears by lowering the gas and passing. Then the speed will change according to the level of the entered gear. Then what about automatic motorcycles which in fact only use gas and brakes?


The automatic motor also has a gearbox component, it's just that in its use it will not be felt. You can feel the automatic motor gear shift if you look closely when you speed up the vehicle and then lower it but it's very smooth.


  • Some Other Gearbox Functions

In addition to the two main functions above, specifically for manual motors, there are several other functions of the gearbox components installed. The first is that it functions to convert motor power into greater power.


So the resulting engine power will turn out to be large so that the vehicle acceleration is higher. The second is to regulate the speed of motion and torque as well as the process of turning around.


The third is to provide a gear ratio in a motorcycle that has a load according to its power. Fourth is to change the turning moment to be transmitted to the machine spindle on a manual motor.


The fifth function is to produce a more stable motor rotation without slipping. You will also be safer driving with this component.


There are several components in the gearbox that support its performance, namely as follows:


  1. The frame is the housing of the gearbox.
  2. Packing is a retainer or clamp so that the transmission oil does not leak.
  3. Out Cove is a cover for the hole on the output shaft.
  4. Worm shaft is a component that functions to continue the rotation of the worm wheel to the output shaft.
  5. Worm wheel is a component to continue the rotation of the input shaft to the output shaft.
  6. The input shaft is a component to continue the rotation of the driving motor.
  7. The oil seal is an oil retainer so that there is no leakage in the shaft.
  8. Oil hole cover is a channel for entering oil.

How to Take Care of the Gearbox Correctly?

As a two-wheeled vehicle owner, of course, you have to pay more attention to every component of the engine and motor electricity. That way you will know how to use a motorcycle so that the engine lasts longer.


Including how to take care of the gearbox so that the gearbox function can run better. There are several treatments that should not be missed if you want this one component to last longer. Given that if damaged then the cost is very large. 1. Routinely Change Transmission Oil


The first way is to regularly change the transmission oil if the quality has decreased. It's not just automatic motors that need to be regularly replaced with transmission oil, as well as all vehicles that use gearboxes.


Without transmission oil that is still of good quality, the components contained in the gearbox will easily be damaged or fall out. Because every time it is used all the components in it will experience friction.


The friction that occurs requires a quality lubricant to function properly. Always check whether the transmission oil needs to be changed during regular service. 2. Choosing the Best Oil Quality


Transmission oil is different from engine oil in that it usually needs to be changed every time it is serviced. Changing the transmission oil is done by checking the condition of the previous oil whether it is not of good quality.


In addition, the use of quality transmission oil will affect the performance of the gearbox later. There is a special oil that needs to be used and make sure the amount is correct. Avoid using used oil because it will create technical problems in the future. 3. Cleaning CVT


Especially automatic motors, gearbox performance is closely related to CVT components. Maintenance is not only carried out on the gearbox, but also pays attention to the CVT space. Make sure the space is kept clean and free of dirt or dust.


That way the gearbox components on the automatic motor will be more durable and work optimally. Try asking a technician to check the condition of the CVT chamber if it needs to be cleaned.


Do you understand what is the function of the gearbox? Make sure every time you do the service, ask the technician how the condition of the gearbox, whether there is a problem or not.


Know, This Is the Function of the Alternator and Its Components


For automotive experts, of course the alternator is not a foreign thing. Especially considering that the function of the alternator is very vital and cannot be separated from the various vehicles that are now the needs of everyone.


To find out the benefits or functions of an alternator, it's a good idea to first know what an alternator is.


Why do these objects become important objects in the automotive world or for motorized vehicles? The following is a discussion of the alternator, its functions and components.


What Is an Alternator?


The alternator is also known as a dynamo. Dynamo itself is a tool or component of a power plant that is in every motorized vehicle, including cars. This is because electricity is an important component in these vehicles.


Here the alternator or dynamo acts as a power generator for all components in the car that require electric power. Components in vehicles that require electricity, for example, such as lights, car air conditioners, car tape and wipers.


To turn on or make these components work properly, an electric power is needed. This is done by a device that can generate or supply electric power, which is called an alternator.


Alternator Function


At this point, you may start to ask, what exactly is the function of the alternator? In accordance with the understanding of the alternator, namely as a means of generating electricity for components of motorized vehicles that require electric power, the function of this alternator is as a supplier.


So far, ordinary people think that the source of electricity in a motorized vehicle or car is a battery. When the components in the vehicle do not function properly, many people assume that the car battery is damaged or has problems.


In fact, it is the alternator that functions as a supplier of electricity to all components in the car. Here, the alternator can function as long as the motor vehicle engine is running. So, the new alternator can function when the engine is turned on.


Why is that? Because the actual electrical energy that flows to the components in the motorized vehicle comes from the conversion of existing kinetic energy into electric power.


From this electrical energy, all components in a motorized vehicle can function. Without an alternator, the battery can only last no more than thirty minutes.


Components in the Alternator



To be able to convert kinetic energy into electrical energy, the alternator cannot work alone. Here it takes a series of cooperation from several components to be able to produce the required electrical energy. These tools are commonly referred to as alternator components.


The components that support the work of the alternator essentially consist of several circuits. The circuit supporting the work of the rotor consists of a battery, alternator, and regulator.


Basically, the alternator itself consists of a rotor, which is a combination of magnetic poles. In the rotor there are several magnetic coils called the stator. Through the magnetic coil, the alternator works by converting motion energy into electrical energy.


As already explained, this alternator can work when the engine is turned on. While the alternator itself can work because of the components in it. Important components in the alternator itself details can be seen below.


  • alternator cover

This section is where all the alternator components. The shape of this component resembles a hole, where the hole also has its own function. Its function is as a cooling device to prevent the engine from overheating, being damaged, or burning.


  • Pulley alternator

This tool is shaped like a wheel. The wheel will be connected to a belt, which causes the pulley to rotate and rotate the rotor oil inside.


  • Bearing

This is the fulcrum of the ends of the rotor coil to rotate. Thus, this bearing also has more than one.


  • Regulator

This regulator has a very important function. Through the regulator, the voltage generated by the alternator remains stable even though the rpm is rising rapidly. With this tool, the machine will not be damaged quickly due to fluctuations in electrical voltage.


  • Diode

The voltage generated by the alternator is usually an alternating current. Through this diode, electric current can be converted into direct current which will flow into components that require electricity.


  • Water Rotor

This tool is in the form of a coil that functions to convert magnetic energy into electrical energy. The electrical energy generated will be processed and then channeled to the brushes and diodes. From here, the electrical power needed by car components is obtained.


The components in this alternator must be able to work perfectly all of them. If one component has a problem, it will affect the overall work of the alternator, and thus the function of the alternator will also not be perfect.


How the Alternator Works


How does the alternator work? Alternators work by relying on components that are in the alternator itself.


Here, the alternator can work when the engine is started. From here the components in the alternator begin to perform their respective functions.


The first, when the engine starts, the alternator pulley starts to work and rotates the rotor coil inside.


Here the diode will then convert the resulting alternating voltage into direct voltage. The resulting voltage will be applied to the battery.


The resulting electrical voltage is usually unstable. This can result in damage to the engine because the engine can become hot, catch fire, and also overheat. Here, the regulator functions to stabilize the electrical voltage generated with the help of a rectifier and a fan that produces air circulation.


Causes of Damage to the Alternator


Because the alternator consists of several components, the damage to the alternator is also caused by several things. For this reason, it is necessary to find the component that is experiencing problems before deciding to replace it. Moreover, there are several damages with the same symptoms.


Damage to the alternator usually occurs due to the addition of an excessive electrical load on the vehicle. For example, the addition of lights and car air conditioning with a large enough energy consumption. This will result in damage to the alternator and shorten the life of the car battery.


Due to Broken Alternator


There are several malfunctions in the vehicle that can be caused by damage to the alternator. There are disturbances that can be seen directly and result in the malfunction of one of the components on the vehicle, and some are only in the form of minor disturbances.


The disturbance caused by a faulty alternator, the first is the emergence of a squeaking sound like the sound of a mouse. This can happen when the end of the rotor coil is no longer resting on the bearing. If not repaired immediately, this will result in not turning the alternator pulley.


Another disturbance caused by a damaged alternator is that the alternator cannot supply electrical energy properly to the battery. If this happens, the vehicle's engine will not automatically start when it is turned on.


Because the function of the alternator is very important for motorized vehicles, the alternator must be maintained so that its condition remains stable, so that it can function normally.


Well, if the alternator is badly damaged, it would be better if you immediately take it to an authorized Auto repair shop. so that it can be handled by an expert.
