Abstract
The utility model discloses an electromagnetic induction type bearing heater belonging to heating and drying devices, particularly to an electromagnetic induction type heating device. The electromagnetic induction type bearing heater is characterized in that electromagnetic coils are enwound on two upright posts of a square iron core consisting of a U-shaped iron core and a linear iron core; a bearing to be heated is sleeved on the linear iron core; and the electromagnetic coils are connected with an AC power supply. When in use, the bearing to be heated is sleeved on the linear iron core, so that the square iron core is formed by linear iron core and the U-shaped iron core; then the AC power supply is connected; under the action of electromagnetic induction, eddy current is formed inside the bearing, and the temperature of the whole bearing increases rapidly and can reach the required level only in more than 10 minutes; and compared with the prior art, the efficiency is improved by more than 5 times, and smoke pollution caused by oil heating is avoided. The electromagnetic induction type bearing heater can be obtained by modifying a step-down start transformer.
Description
Technical field
The utility model belongs to the heating, drying device, particularly induction heater.
Background technology
After all being heating, considerable plant equipment middle (center) bearing is installed on the axle, so often need be in maintenance with new bearing heating, usual way is new bearing to be placed in the oil bath heat, the oil temperature reaches 100 ℃ of-120 ℃ of heating and is no less than 20 minutes, the heating bearing approximately needs more than 1 hour time, therefore changing motor bearings needs 3,4 hours time, and production efficiency is low, and can produce pollution when adding deep fat.
The utility model content
Use the low deficiency that pollution is arranged of oil bath heating bearing efficient in the prior art in order to overcome, the purpose of this utility model provides a kind of induction bearing heater, and the fast efficient height of this induction bearing heater speed pollutes light.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of induction bearing heater, it is characterized in that: twine solenoid on two columns of the square shape iron core of forming by U-iron core and in-line iron core, be heated bearing holder (housing, cover) on the in-line iron core, solenoid is connected with AC power.
The utility model will be heated bearing holder (housing, cover) on the in-line iron core when using, in-line iron core and U-iron core are formed the square shape iron core, connect AC power, evenly heat up in the inner rapid integral body of eddy current that forms of electromagnetic induction lower bearing, generally only need just reach the temperature that needs in more than 10 minute, raise the efficiency more than 5 times than prior art, and avoided adding the smoke pollution that deep fat produces.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model,
Among the figure, 1.U sections core, 2. solenoid, 3. the yi word pattern iron core 4. is heated bearing, 5. AC power.
Embodiment
Embodiment of the present utility model is, as shown in the figure:
Claims (1)
1. induction bearing heater is characterized in that: twine solenoid on two columns of the square shape iron core of being made up of U-iron core and in-line iron core, be heated bearing holder (housing, cover) on the in-line iron core, solenoid is connected with AC power.
