Introduction of temperature limit of gear reducer, affected by temperature

 We have already talked about the price and characteristics of gear reducers, and we also have a general understanding of gear reducers. So, have you known about temperature?The temperature limit requirements of gear reducers are also very particular, let us understand together below.

Are the temperature limits of all parts of the gear reducer the same?

What I want to tell you here is that the gear reducer is composed of different structures, and different structures determine the temperature rise or temperature difference of different parts of the gear reducer.Then in this chapter, let's take a look at the temperature limits of different parts of the gear reducer.

 (1) The temperature rise of the core in contact with the winding (thermometer method) should not exceed the temperature rise limit (resistance method) of the winding insulation in contact, that is, 60°C for Class A, 75°C for Class E, and 80°C for Class B. Class F is 100°C and Class H is 125°C.

 (2) The temperature of rolling bearings should not exceed 95℃, and the temperature of sliding bearings should not exceed 80℃.Because the temperature is too high, the oil quality will change and the oil film will be destroyed.

 (3) In practice, the case temperature is often based on the fact that it is not hot.

(4) The surface of the squirrel cage rotor has large stray losses and high temperature. Generally, it does not endanger the adjacent insulation.It can be estimated by applying irreversible color paint in advance.
