Does high temperature affect the use of planetary gear reducer?

For a planetary reducer in normal use, its temperature rise under rated load is theoretically independent of the ambient temperature, but it is actually affected by environmental temperature and other factors. The following is about the influence of temperature on the use of planetary reducer.

Planetary reducer is a kind of transmission that is driven by gears to achieve the purpose of speed reduction. It is a type of planetary reducer that is often seen and used among the reducers.

1、 The limiting operating temperature of the insulating material refers to the temperature of the hottest point in the winding insulation during operation of the planetary reducer within its design life expectancy. If the operating temperature exceeds the limit operating temperature of the material for a long time, the aging of the insulation will be aggravated and the service life will be greatly shortened. Therefore, the temperature is one of the main factors for the life of the planetary reducer in operation;

2、 The temperature rise is the temperature difference between the planetary reducer and the environment, which is caused by the heating of the planetary reducer. The temperature rise is an important indicator in the design and operation of the planetary reducer, which marks the degree of heating of the planetary reducer. During operation, if the temperature rise of the planetary reducer suddenly increases, it indicates that the planetary reducer is faulty, or the air duct is blocked or the load is too heavy;

3、 When we use the planetary reducer, its iron core will suffer from iron loss in the alternating magnetic field. After the winding is energized, copper loss will occur, as well as other stray losses. These will cause the temperature of the planetary reducer to rise.

In addition, the planetary reducer will also have heat dissipation. When the heating and heat dissipation are equal, the equilibrium state is reached. If the temperature does not rise any more, it is stabilized on a horizontal plane. When the heating increases or the heat dissipation decreases, the balance will be broken, causing the temperature to continue to rise, expanding the temperature difference, which will increase the heat dissipation, and a new balance can be reached at a higher temperature.
