Description
Technical field
Rolling bearing installation technical field of heating is the utility model is related to, more particularly to a kind of large-size rolling bearing oil bath adds
Hot device.
Background technology
In the installation process of large-size rolling bearing, because its magnitude of interference is excessive, it is therefore desirable to which the method using heating is entered
Luggage is matched somebody with somebody.Because the plant equipment of smelter belongs to big machinery more, the thus large-scale axis of rolling used in metallurgical machinery
Hold and generally installed using ten thousand methods of heating, the method for use ten thousand of bearing can be improved by so doing one, and giving full play to bearing should
Some efficiency, two help to extend the service life of bearing.Two kinds of heating ten thousand methods of installation of existing heating：First, oil sump heats skill
Art, it is that bearing is placed in the oil sump equipped with high ignition point oil, and oil sump heats below by burn wood, makes its bearing fully swollen
Swollen, to be easy to put axle, oil temperature heating is typically no more than 110 DEG C -120 DEG C；Second, current vortex heating technique, current vortex
Heating technique is that AC rectification is become into direct current, then direct current is converted into the high-frequency and high-voltage that frequency is the 40kH of 20kHz mono-
Electricity, high frequency electric produce the alternating magnetic field of change at a high speed by coil, when the magnetic line of force in magnetic field is by can be with the bearing of magnetic conduction
When can produce countless small vortex in Bearing inner, bearing is generated heat at a high speed in itself, so as to reach the purpose of heating bearing, make its axle
Abundant expansion is held, to be easy to put axle.But both heating ten thousand methods of installation there are deficiency：1. oil sump is below by burning
Timber heating means, Heat artificially operation, the heat time is oversize, wastes time and energy, waste of resource, pollutes site environment, heating effect
Rate is low, constrains installation progress, because environmental requirement, enterprise have not used；2. current vortex heats ten thousand methods in heating process
The hot charging temperature of rolling bearing is difficult to control, and shrinkage-fit bearing is influenceed by the operative skill of installer, easily causes bearing
Inside and outside circle temperature is inconsistent, differs l0 DEG C of one 20 DEG C of temperature difference, causes inside and outside circle expanded by heating inconsistent, ball extruding raceway,
Stress concentration is produced, causes inside and outside circle deformation；3. current vortex is heated in heating process, bearing is exposed in air all the time, make
Into high-temperature oxydation, shorten bearing service life.Therefore, it is necessary to which a kind of technical scheme solves the above problems, just it is particularly important.
