The speed reducer has the function of protecting the engine in the transmission. During procedure, the speed reducer is normally subjected to a big torque. When the overload is definitely sent to the electric motor, only the overload amount is divided by the decrease ratio. If it is normally straight paid for by the motor, the motor may be broken. When the overload can be extremely huge, the deceleration chance is definitely damaged 1st, and the speed reducer can be used only after replacing the extra parts. The price is definitely fairly low. If the engine is straight broken, the maintenance is definitely fairly gradual and the price is certainly high.
Adding a speed reducer can easily decrease the instant of inertia, generally the square of the rate ratio is reduced, which usually is usually extremely important to get control, and can easily control the begin and prevent and shifting in period. Raising the torque through the gearbox can be equivalent to increasing the input power, which can reduce the power required to insight the motor (in the case where velocity rules can be required). Generally, the motor is usually even more expensive than the gear box, so consider using a gear reducer. The functioning concept of the speed reducer varies based on the type of gear reducer. At present, the efficiency of the gear reducer belongs to the Tomas Taper Lock Pulley planetary equipment gear box. The transmitting system of the planetary equipment gear reducer is usually a equipment. The structure diagram is not really attracted, it is usually extremely basic. Imagine having two large and one little circles, two circles concentric, and three various other little circles in the ring part between the two circles. The largest one of all the circles is definitely the inner band equipment, and the various other four little circles are things. The middle one is usually known as the sunlight wheel, and the various other three small rounds are called the planetary wheel. The servo engine forces the sun gear of the gearbox, and the sun equipment drives the planetary gear supported on the inner band equipment. The planetary gear transmits the meshing transmission with the external ring gear to drive the result shaft connected to the outer ring gear to achieve the deceleration. Purpose, the reduction ratio is certainly related to the specs of the gear teach. As for the selection, it is normally related to the kind of servo motor used and the technical requirements in the application.
