The gear reducer has the function of protecting 
the engine in the transmission. During procedure, the Dry Screw Vacuum Pumps gearbox is put through to a big torque. When the overload is definitely sent to the engine, only the overload quantity is certainly divided by the reduction ratio. If it can be directly borne by the engine, the electric motor may be broken. When the overload is normally extremely large, the deceleration opportunity is normally damaged 1st, and the gear box can be utilized just after changing the extra parts. The price is normally fairly low. If the motor is definitely straight broken, the maintenance is normally relatively sluggish and the cost is normally high.
Adding a reducer can easily decrease the moment of inertia, generally the square of the speed ratio is certainly decreased, which usually can be extremely important pertaining to control, and can easily control the begin and quit and shifting in period. Raising the torque through the gear reducer is definitely similar to raising the input power, which can reduce the power needed to insight the electric motor (in the case where swiftness legislation is certainly required). Generally, the electric motor is certainly more expensive than the speed reducer, so consider using a speed reducer. The working concept of the gearbox varies based on the type of speed reducer. At present, the efficiency of the gear reducer goes to the Tomas planetary equipment speed reducer. The transmission system of the planetary gear gearbox is usually a gear. The framework diagram is certainly not drawn, it is definitely extremely simple. Imagine having two large and one little circles, two circles concentric, and three other small circles in the band portion between the two circles. The largest one of all the circles is the internal band equipment, and the various other four little circles are things. The middle one is certainly called the sunlight wheel, and the additional three little rounds are known as the planetary wheel. The servo electric motor memory sticks the sun equipment of the gear box, and the sun gear memory sticks the planetary gear supported on the internal ring gear. The planetary equipment transmits the meshing transmitting with the external ring gear to drive the output shaft linked to the external band equipment to attain the deceleration. Purpose, the decrease ratio is usually related to the specifications of the equipment teach. As for the selection, it is usually related to the type of servo engine utilized and the technical requirements in the software.
