What are the faults of Flender Flander reducer when it is frequently started and stopped

Gear wear: When frequent start and stop, the impact load under the reducer gear increases. When the start is started, the torque output by the motor is suddenly applied to the gear, resulting in a large impact force; when the gear movement suddenly stops, it will also produce a reverse impact force. Under the action of this impact load for a long time, the gear teeth surface is prone to wear, pitting, peeling and peeling, etc., and in severe cases, it may even cause the gear teeth to break, affecting the normal transmission of the reducer.

Bearing damage: Frequent start and stop will cause the bearing inside the reducer to be subjected to alternating load. When the shaft starts up, the speed of the shaft will rise rapidly, and the bearing will bear large radial and axial forces. When stopped, the inertia of the shaft will cause the bearing to be subjected to additional impact force. This alternating load will accelerate the wear of the bearing, increase the clearance of the bearing, causing the bearing to generate heat and vibration, and even cause jamming, affecting the stability and reliability of the reducer.

Oil leakage of oil seal: Frequent start and stop may cause the internal pressure fluctuation of the reducer internal pressure fluctuation, and the pressure increases. When the start is started, the oil temperature drops, and the pressure decreases. This frequent changes in pressure will cause a greater pressure impact on the oil seal, causing the sealing performance of the oil seal to decrease. At the same time, the vibration of the reducer will also affect the fit of the oil seal, resulting in damage to the oil seal, resulting in oil leakage, which will not only pollute the working environment, but also cause the internal lubricating oil of the reducer to be insufficient, affecting its lubricating and heat dissipation effect.

Motor overload: When frequent start and stop, the motor needs a large starting current at the moment of starting, which is generally several times the rated current. Due to the inertia and load characteristics of the reducer, during frequent start and stop, the motor may be in a high load state for a long time, which can easily cause the motor overload protection operation. If the overload condition is serious and lasts for a long time, it may also cause the motor winding to be damaged overheating and insulation, or even burn the motor.

Coupling damage: When frequent start and stop, the coupling must bear large torque changes and impact loads. When starting, the coupling needs to quickly transmit the motor torque to the reducer; when stopped, it must bear the effect of inertial force for a long time. Under this working condition, the elastic components of the coupling are prone to fatigue and damage, and the connecting bolts may also be loose and broken, which affects the normal transmission of power and even causes the equipment to stop.
