Gears are used to transfer power from one part of a machine to another. For example, in a bicycle, it is a gear for power from the pedals to the rear wheels. Similarly, in a car, gears transfer power from the crankshaft (the rotating shaft of power from the engine) to the drive shaft running underneath the car, which ultimately powers the wheels. We can connect any number of gears together and they can come in different shapes and sizes. Whenever we transfer power from one gear to another, we can do one of two things: gear box bicycle gear increases speed: if two gears are connected together, the first gear has more than the second, and the second gear must turn faster to keep up. This arrangement therefore means that the second wheel rotates faster than the first, but with less force.
Change direction: When two gears are engaged, the second always turns in the opposite direction. So if the first rotates clockwise, the second must rotate counterclockwise. We can also use specially shaped gears to turn the force of the machine at an Angle. For example, in automobiles, the differential (the gearbox in the middle of the rear axle of a rear-wheel drive vehicle) uses conical bevel gears to turn the drive shaft power 90 degrees and the rear wheels.
A gearbox is a mechanical device used to increase/decrease by reducing/increasing torque. It consists of two or more gears, one of which is driven by a motor. The output speed of the gearbox is inversely proportional to the gear ratio. Gearboxes are often preferred in constant speed applications, such as conveyors and cranes, to provide increased torque.
Gear box includes a drive gear of a certain diameter, and the drive mechanism (motor, turbine, diesel engine, and so on) connected to another smaller gear gear (if driven mechanism drive faster than the driving mechanism of high) diameter (if the speed of the driven mechanism should be less than the speed of the drive mechanism) connected to be driven mechanical load. Just speed/torque increase/decrease or vice versa mechanism. This is a mechanical motor accessory.
Convert the motor to high speed, low torque to low speed and high torque (no idle even at X-MAS).
Low speed/high torque to high speed/low torque.
Sometimes the "gear head" operates with a 1:1 gear ratio synchronous belt or chain to reduce transmission of motor vibration to the load.
Often overlooked - the gear head reduces the motor inertia in proportion to the square of the motor's transmission ratio. For example. If we install a gear head with a ratio of 4:1, 2000 RPM will harmonize to 500 RPM, but the load inertia will be reduced by 16 times.
If worm gear is used, the system automatically locks the mechanism (we cannot move the load until the motor rotates).
There are others that have their own characteristics (for example, ball screws that are also gear heads, but we don't usually call them gear heads). Also note that gears don't run for free, which means we have less power output, which means gears have some efficiency. There are various types of gear heads: spur, planetary, first, multistage, harmonic, spur layman, (cycloid), worm, etc., as well as a combination of the above, but this is a whole, separate science.
