Bearing is an important part of a widely used in mechanical transmission, but in the process of assembling repair, due to the tolerance matching requirements of "interference" bring great difficulty to the operation, usually to bearing the outside pressure or flame heating, cooking oil heating or use the most primitive methods of technology with a hammer percussion, this method is easy to cause shaft is galling, bearing damage, noise increase, reduce the service life and other large energy consumption, the worker labor intensity higher defect, our factory developed newly for this YG51 DKQ - I ~ V type fully functional electronic SKF 6206 Bearing Clearance [url removed, login to view] collar heater solved this difficult problem, which in the bearing application field for domestic initiative. Used for heating the bearing inner diameter in the range of 115-200 - mm
This machine use transformer short-circuit loop of large current and eddy current heating principle of the motor, the introduction of European and American technology and related electronics, temperature sensor with high precision, electronic numerical control display. Bearing (set) temperature heating choice parameter table accurately using the metal thermal expansion principle, for bearing (set) to provide data and assemble with shaft.
One, the main structure:
Host by the power transformer, moving iron core (matching), temperature sensor, electronic numerical control digital display part.
Second, the use and operation:
1, according to the requirements of the bearing collar and shaft fit, Chad parameter selection table from the heating temperature.
2, according to the inner diameter of the bearing size, choose a different diameter of core column, and its moving iron core spin on the heater panel, will heat the bearing sleeve on the moving core core columns, then put the panel together with the core of moving iron core column into, make the transformer form a closed magnetic circuit.
3, will the power of the heater step switch to the corresponding gear, turn on the juice and according to the bearing, collar diameter size, heating time within 30 seconds to three minutes to complete.
4, insert the plug of the core temperature sensor heating stand sensor in the socket, and then put the sensor temperature sensing head bearing or sleeve within the inner ring, and the bearing pressure on thermal head and working on the bedplate, make its good contacts, so that the temperature measurement accuracy.
5, open the temperature digital display controller, and open the power switch, heat, temperature digital display continuously display bearing heating temperature, temperature rise to reserve the ideal temperature, can cut off the power supply, pull out iron core, remove the trunnion bearing, set into the assembly panel, which is completed.
Four, matters needing attention:
1, the heater warming faster. After turning on the power supply, to keep an eye on the temperature display, after waiting for temperature rise to book value, immediately turn off the power supply, so as to avoid high temperature bearing microstructure.
2, remove has heating bearings must pay attention to safety, prevent burns.
3, after using temperature digital display to push into the machine, lest meet bad and cut off all the power.
