VEL INDUCTION HEATERS FOR BEARING, MOUNTING & DISMOUNTING


Application:
  • Shrink Fitting (gear/pinion assembly, Wheel assembly, rotor casing, bearings, Reactor end fitting, etc.)
  • Brazing
  • Heat Treatment
  • Hardening (for higher case depth)
  • Forging
  • Melting

Introduction:

VEL Induction Heater (Type VEL/MF/BMD/40) is specially designed & manufactured for mounting & dismounting of shrink fit components like bearing, gear assembly, rotor casing, end fitting of reactor tube etc. It is a high po wered electronic equipment with control system, interlocking, protective devices and inductor.

Technical Data 
INPUT Power Supply
440V AC, 3ph. 50 Hz
Output power rating
30 kW
Output frequency
6 kHz
Maximum heating temperature 300°C
Heating time
150°C in 30 sec for all inner races
Timer
0-300 sec.


Special Feature of VEL/MF/BMD/40 :

*Faster out turn of wheel. (Single fitment/removal of bearing sleeve in just40sec.)

*No rejection of axle/gear assembly/traction motor during fitment/removal of   bearing/gear/pinion. (Also, precision shrinkfit of reactor tube assembly possible)

*No residual magnetism in the bearing while heating, hence longer life of bearings.
  (We also save on demagnetisation cycle time)

*Equipment ready for use immediately. (Instantaneous start)

*Precision power control & uniform heating, so no distortion, no metallurgical change   & no decolouration of bearings. (So the bearing could be reused)

*Most efficient, takes balanced 3 phase current without KVAR loading (Lesser load   on electric system)

Superiority Over Conventional Methods of Removal
of Shrinkfit Components:


oilbath


OIL BATH :


Mess of oil, heat of the bath or hot plate, vapour of oil, smoke, fear of fire hazards, requirement of high degree of manual skill & efforts.


Hyfraulicpress


HYDRAULIC PRESS :


It has the risk of damaging the inside surface of inner race of bearing.


Hammerblow


HAMMER BLOW:


Apart from the risk of getting the bearing damaged, requires high manual effort.


Gastorch


GAS TORCH :


Apart from damaging the bearing, has a good chance of spoiling the axle shaft.
