First look at the effect of the NTN bearing heater:
The primary effect of the NTN bearing heater is the support; the essence of the support is to be able to bear the radial load. It can also be understood that it is used to fix the shaft. That is, the fixed shaft can only complete the transformation; and the axial and radial directions are controlled. The result is that the motor has no bearing. The bottom can not work. Because the shaft can move in any direction; while the motor requires the shaft to change only when it is working. In theory, the effect of the transmission cannot be completed; not only that; the bearing also affects the transmission. In order to reduce this effect, it is necessary to complete outstanding smoothness on the bearings of the high-speed shaft; some bearings are now smooth; they are called pre-smooth bearings; and most of the bearings need to have smooth oil; Conflict does not only add energy; what is even more frightening is that it is very simple to damage the bearing. The idea of ​​turning a sliding conflict into a rolling conflict is one-sided; because there is something called a sliding bearing.
Secondly; the professor describes the working principle of NTN bearing heaters:
1. Check if the wiring between the plug and the socket is common; the grounding should be excellent; then puncture the plug into the power socket with the control switch.
2. The main machine is a special layout transformer; the movable yoke is used to directly pass the sleeve bearing or other heated workpiece. During operation; the main power supply is turned on; the short circuit current is induced in the workpiece (corresponding to the secondary winding) and heated.
3. Press the start button; the host is powered; at this time, the green indicator light is red and the button is pressed; the red light is off and the green light is off. At this point; the debugging is completed; it can be put into use.
4. Turn the function selection switch to the manual control position; close the power supply; then the red indicator light is on.
We now know the effect and working principle of the NTN bearing heater that the professor described for us; trust knows that the bearing can work better for us.
