What are the effects of changes in equipment working time and frequency on the service life of NGW83-250 planetary gear reducer

The changes in equipment working time and frequency have a significant impact on the service life of NGW83-250 planetary gear reducer, as follows:

The impact of working hours on service life

Intensifying wear: The longer the working time, the more severe the wear of internal transmission devices such as gears and bearings in the gearbox. For example, prolonged operation can cause the gear teeth to constantly rub against each other, leading to problems such as tooth wear and root fatigue cracks, thereby shortening the service life of the gearbox.

Causing overheating: Long term operation can cause the temperature of the gearbox to rise, as friction between components such as gears generates a large amount of heat. High temperature can decrease the performance of lubricating oil, deteriorate the lubrication effect, further increase frictional resistance, accelerate component wear, and even cause gear deformation, bearing failure, and other faults, seriously affecting the service life of the gearbox.

The impact of operating frequency on service life

Increased fatigue damage: High operating frequency means that the gearbox frequently starts and stops, and each start and stop will cause internal components to bear an impact load, which will accelerate the fatigue process of the components. For example, during frequent start stop processes, gears are subjected to alternating stress on their tooth surfaces, which can easily lead to fatigue pitting, peeling, and other phenomena. Bearings can also shorten their service life due to frequent impacts.

Causing current fluctuations: If the operating frequency of the equipment changes and the motor circuit is frequently connected and switched, the load current will fluctuate frequently, thereby generating significant additional force on the winding of the reducer. These forces are related to the square of the current, and long-term effects can damage the insulation of the winding, causing short circuits or open circuits, making the gearbox unable to work properly.

Influence on lubrication effect: Changes in operating frequency may cause changes in the flowability and viscosity of lubricants at different frequencies, thereby affecting lubrication effect. For example, rapid frequency changes may prevent lubricating oil from covering the friction surface in a timely and sufficient manner, resulting in dry or semi dry friction between components, exacerbating wear and reducing the service life of the gearbox.
