Bearing Heater

Abstract

The invention discloses a bearing heater. The bearing heater comprises a heating rod, an iron core, an induction coil, a power supply driving control module, a silicon controlled rectifier, a mutual inductor, and an operating display panel, wherein the heating rod is connected with the iron core; the induction coil is wound around the iron core; the power supply driving control module is connected with the silicon controlled rectifier for controlling the switch-off / switch-on of the silicon controlled rectifier; the mutual inductor is connected with the power supply driving control module; the power supply driving control module comprises a total-power interface and a half-power interface; the induction coil comprises a first induction coil and a second induction coil which are connected in series; the tail end of the first induction coil is connected to the half-power interface while the tail end of the second induction coil is connected to the full-power interface; the power supply is connected to the first end of the first induction coil; and the operating display panel is connected with the power supply driving control module. According to the bearing heater, real-time regulation by combination with software and hardware is carried out for the magnitude of the current specific to bearing workpieces of different specifications under the premise of rated output power, thereby improving the universality of the bearing heater and improving the production efficiency.

Description

technical field [0001] The invention relates to the field of electrical product testing equipment, in particular to a bearing heater. Background technique [0002] Bearing heaters, also known as electromagnetic induction heaters, are one of the heating tools for metal workpieces. Utilize the principle that the metal generates eddy current in the alternating magnetic field and absorbs the heat generated to realize the principle of rapid heating of the metal workpiece, and heats various metal parts such as bearings, gears, and bushings. The problem with this technical solution is that: due to the different specifications of various bearings, their inductive reactances are also different. When designing the rated power of the heating equipment, only one and a very similar limited number of bearings can work at the rated power output state when heated, while most of the other bearings can only absorb less than or far less than the equipment when heated. Therefore, there will b...

Problems solved by technology

The problem with this technical solution is that due to the different specifications of various bearings, their inductive reactances are also different.

When designing the rated power of the heating equipment, only one and a very similar limited number of bearings can work at the rated power output state when heated, while most of the other bearings can only absorb less than or far less than the equipment when heated. Therefore, there will be a large waste of redundant capacity of bearing equipment with a diameter within a certain range, and the use of the same bearing heater cannot quickly heat most of the same bearings, resulting in low production efficiency and poor versatility of the bearing heater. sex problem
