Description of the invention (I) Field of invention (please read the precautions on the back side before filling in this picture) This invention is about the heating of bearings and other objects that need to be located on shafts, pipes, etc. Background The heating should be well-known in this technology, and it is usually done by a device that forms the primary winding of the transformer and forms a secondary winding with a bearing ring. This method provides a horseshoe-shaped structure for the primary winding and has a connector To achieve the completion of the road, the connector is suitable for accepting the bearing should be suspected. • There are many types of heaters in use at present. However, its use is limited by several shortcomings, which are not sticky. Originating from Qiying heating currently involves the fact that high-power currents (often several kilowatts) pass through Weiying coils to generate high heat in the guide metal; and the primary embroidery set is usually at the normal power frequency and usually makes it difficult to lose power The large size. The S-disadvantage related to the prior art S is that the bearing needs to be demagnetized during or after the heating operation. One of the items of the present invention is to avoid certain shortcomings of the prior art S And provide a device that is easy to carry and does not demagnetize the bearing or the encounter. • Wire, according to the present invention, a pre-heater for Chen-shaped objects includes a clip-shaped magnetic core can be opened to accommodate the object to be heated , A primary silk set, and an off-frequency current source such as a switch or power supply. In this specification and the scope of patent application, the "high-frequency galvanic flow" project means that there is a small current whose frequency exceeds 60 times / second. In other words, the "Yi-Yu" project means that a frequency is away from the upper stream (frequency of 60 Hz) obtained from the normal Xiaoyuan main line. A 4 (210X297 eaves) 215140 V. Description of invention (ζ) is a better one in the present invention The core is ferrite. An important aspect of the present invention is that, because of the novel use of high frequencies that can be generated by small high-frequency generators, it can be made into a small unit that is easy to lose. The low magnetic flux density in the Liu Huiwei core and bearings and where the vibration gradually disappears due to the resonance mode of operation, this high frequency small current means that little or no magnetization occurs and demagnetization steps are avoided. —The European Patent Office's investigation revealed the following prior patents: British Patent No. 1454783, European Patent No. 027306, US Patent 43 1 1 896, US Patent No. 3895295, US Patent No. 3187155, European Patent No. 14309 No. 1 because there is no prior art. The high frequency avoids magnetization, so the above [those do not explain the invention, but tend to emphasize the original step.

Description of the invention (>) 螞 4 is a schematic diagram of the high-frequency source housing for use in the present invention; 黼 5 is the square ring of the two-blue power supply of the heater.诮 Refer to _1 and 2,-the primary coil 10 is set on the iron gas core 12, which is hinged at 14 ·, so that the bearing or Chen-shaped object can be installed at point A or B. The primary coil 10 is connected to a switched-mode source 40, and is connected to this power supply by a connector 16. The circle 4 shows a schematic diagram of the housing of the switch-mode power supply 40, and the circle of the road block is shown in FIG. Majestic Fishy magnetic core 12 is enclosed in a heat-resistant and non-conducting shell 13. Please refer to Chapter 3, Two Temperature Sensitive Mass Enclosures (1C) 18 are installed on a spring clip 20; one of them measures the temperature of the bearing or ring-shaped object, and the other measures the environment or reference temperature. The two IC 18 are connected to the switch-type source 40, and are connected to the power source via the connector 22. 4, referring to FIG. 4, in this form of the invention, the open power supply 40 is placed in an aluminum box 24. The primary coil 10 is connected via a socket 26, and the temperature sensor 18 is connected via a socket 28. The main power supply is connected via open 30 and fuse 32. The temperature control of the over-meter 18 is accomplished by a potentiometer 34. The switch-mode power supply 40 is activated by the button 36, and the light emitting diode (LED) is used as an indication of the active state. Please refer to Garden 5, the circuit current to Lulan power supply 40 is rectified and smoothed using electrolytic capacitor 44 to produce a stable DC current.

Description of the invention (4) Understand the circuit included), and then supply the broadcasted high voltage and high frequency current to The primary coil 10, this coil then heats up any matching element bearing 50. In an example of the present invention, a kind of iron gas magnetic core is selected and selected. The magnetic core is suitable for use at a frequency of 20 kilohertz (KHZ). The invention uses the model Philips A 3 2 0 KP 9012, the size is 9 4 mm long, 27 mm wide and 16 mm thick, and several such cores are combined together to form a heater as shown in FIG. 1 . These cores are wound around 1 5 coils 2 X 1 mm copper wire. The invention includes an auxiliary rib circuit to enable the main circuit 40 to generate a frequency factor of 1 at the primary winding 10 with a power factor of 1. This ensures that the maximum power is always output to the load 50. (Under variable load conditions, the power factor can change, resulting in reduced power in the bearing or the shaft.) This circuit also has the function of switching the transistor at zero current to reduce losses therein. The variable temperature setting can be obtained by the control device 34, and at the set temperature point, the switching power supply 40 is automatically disconnected together with the same audio buzzer. The measurement of temperature rise can be displayed using a liquid crystal display. When setting the workpiece to be heated, if the overpass of the temperature detector is not complete, or the temperature detector is not installed on the workpiece, a safety circuit will invalidate the open source power supply and inhibit the above sources.
