What is the use of the speed reducer, why use a gearbox?

The gear box has the function of protecting the electric motor in the transmission. During operation, the gear box is usually exposed to a sizable torque. When the overload is certainly transmitted to the engine, just the overload amount is definitely divided by the decrease ratio. If it is definitely directly borne by the motor, the motor may be broken. When the overload is normally very huge, the deceleration chance is certainly damaged first, and the gearbox can be used just after changing the extra parts. The cost is relatively low. If the engine is directly damaged, the maintenance is definitely relatively slow and the price is certainly high.

Adding a gearbox can decrease the moment of inertia, generally the block of the speed ratio is certainly reduced, which usually is very important to get control, and can control the begin and quit and shifting in period. Raising the torque through the gear Rotary Air Compressors reducer is comparative to raising the insight power, which can decrease the power required to input the engine (in the case where swiftness rules is definitely needed). Generally, the electric motor is certainly more expensive than the gearbox, so consider using a reducer. The working theory of the gear reducer varies according to the type of reducer. At present, the overall performance of the gearbox belongs to the Tomas planetary gear gear reducer. The transmission system of the planetary equipment gearbox is a equipment. The structure diagram is usually not attracted, it is usually very simple. Imagine having two huge and one little circles, two circles concentric, and three other little circles in the band part between the two circles. The largest one of all the circles is normally the inner band gear, and the other four small circles are things. The middle one is definitely known as the sunlight wheel, and the various other three little rounds are known as the planetary wheel. The servo motor runs the sun equipment of the speed reducer, and the sun gear drives the planetary equipment backed on the internal band gear. The planetary gear transmits the meshing transmission with the external band equipment to drive the result shaft linked to the outer ring gear to obtain the deceleration. Purpose, the reduction ratio is usually related to the specifications of the equipment teach. As for the selection, it is definitely related to the kind of servo engine used and the specialized requirements in the program.
