What is the temperature rise of the gear reducer

we are atGear reducerIn the description of fever, there is a word called temperature rise. What does temperature rise mean? Why not use the common form of how much temperature to express? ght by: wy temperature rise is the temperature difference between the gear reducer and the environment, which is caused by the heat of the gear reducer. The iron core of the gear reducer in operation will produce iron loss in an alternating magnetic field, copper loss will occur after the winding is energized, and other stray losses. These will increase the temperature of the gear reducer. On the other hand, the gear reducer will also dissipate heat. When heat generation and heat dissipation are equal, the equilibrium state is reached, and the temperature no longer rises and stabilizes at a level. When the heat generation increases or the heat dissipation decreases, the balance will be broken, and the temperature will continue to rise, and the expansion of the temperature difference will increase the heat dissipation, reaching a new balance at another higher temperature. However, the temperature difference at this time, that is, the temperature rise, has increased compared to before. Therefore, the temperature rise is an important indicator in the design and operation of the gear reducer. It marks the degree of heat generation of the gear reducer. During operation, such as a gear reducer The sudden increase in temperature indicates that the gear reducer is faulty, or the air duct is blocked or the load is too heavy.
