The influence of temperature on the gearbox

With the discovery and recognition of the advantages of high transmission rate and smooth operation of reducers, this equipment has been widely used in various industries; However, as the temperature gradually increases, many users will also ask the editor if the temperature changes will have any impact on the operation of this device. So today, the editor will briefly introduce the relevant content and help solve this doubt for everyone:
1. The temperature difference between the gearbox and the environment is called temperature rise, which is often caused by equipment heating and indicates the degree of heating; If the temperature suddenly increases during operation, it often indicates that the equipment has malfunctioned, or the air duct is blocked or the load is too heavy.
2. During the expected lifespan of the gearbox design, the temperature of the hot spot in the winding insulation of the equipment during operation is the working temperature of the insulation material; If the operating temperature exceeds the limit working temperature of the material for a long time, the aging of its insulation will intensify and the service life will be greatly shortened; So we can see that temperature is one of the main factors affecting the lifespan of the gearbox during operation.
3. The iron core of the gearbox in operation will experience iron loss in an alternating magnetic field, and copper loss will occur when the winding is energized, which are all reasons for the temperature rise.
4. The gearbox also releases heat - when the heat and heat dissipation are equal, reaching an equilibrium state, its temperature will no longer rise and stabilize at a certain level; When the heat generation increases and the heat dissipation decreases, the balance will be disrupted, causing the temperature to continue to rise, expanding the temperature difference and increasing heat dissipation, and reaching a new equilibrium at another higher temperature.
Generally speaking, when the temperature of the gearbox exceeds the normal operating temperature range, or when its temperature rise exceeds the specified range, or when the temperature rise suddenly increases at low loads although it does not exceed the specified range, it often indicates that the equipment has malfunctioned and needs to be dealt with in a timely manner.
