Abstract
Heater of bearings mainly used in bearing , gears, bushings, bushings, diameter, pulley, shrinkage, connectors, etc. Various types of metal heat, bearing heater by heating of inflation, achieve a assembly needs. We usually use is inductive bearing heater. This heating temperature easy control, can the bearing type heat range. This bearing heater needs a temperature controller for the heating temperature controlling, control interface in the whole process of temperature control is an important position. This design control interface system is 16F877 PIC as control core and temperature testing system, amplification system, A/D conversion, I/O devices composed A combination of equipment, the temperature control system of the temperature control system is mainly used for bearing heater bearing heating temperature testing, through the keyboard by default heating temperature, temperature of heating tube digital display, and displayed by LED heating condition etc. Function.
Keywords: bearing heater, Human-machine interface, Keyboard technology, LED
