Gear reducers are popular in many mechanical fields, but the normal use of gear reducers is very important. Is the work of the gear reducer affected by temperature when working?
1. The limit operating temperature of the insulation material refers to the maximum hot spot temperature of winding insulation within the life expectancy of the gear reducer design. If the operating temperature exceeds the material’s limit operating temperature for a long time, the insulation aging will increase and the service life will be greatly shortened. Therefore, in the operation of gear reducer, temperature is one of the main factors affecting life.
2. Temperature rise is the temperature difference between the gear reducer and the environment, which is caused by the heat of the gear reducer. Temperature rise is an important index in the design and operation of gear reducer, which indicates the degree of heating of gear reducer. In operation, if the temperature rise of the gear reducer suddenly increases, it means that the gear reducer is faulty, or the air channel is blocked, or the load is too heavy;
3. The iron core of the running gear reducer will produce iron loss, copper loss and other stray losses in the cross-change magnetic field when the winding is powered on. All of this increases the temperature of the gearbox and, on the other hand, the gearbox dissipates heat. When the heat and heat dissipation are equal, it will reach equilibrium, and the temperature will no longer rise, but will stabilize at a level. When heating increases or cooling decreases, the balance will be broken, the temperature will continue to rise, the temperature difference will widen, the cooling will increase, and a new balance will be reached at another higher temperature.
Gears and gearboxes are subject to temperature when working, so a stable temperature needs to be maintained when the gear reducer is working to make the gear reducer work better and extend its operating life.
