1. Introduction

TheSKFBearingHeaterTMBH1isintendedforheatingrollingbearingswith

aninnerdiameterupto80to100mm(3-4in)andamaximumcorresponding

weightof4-5kg(9-11lb).

Otherring-shapedmetalcomponentsformingaclosedcircuitsuchasgears,

pulleys,bushingsandshrinkringscanalsobeheated.

Thisapparatususesapatentedmethodofheatingbasedonhighfrequency

induction.Thisnewconceptcatersforoptimizedefciencyandisatrulyportable

unit.

Theunitissuppliedwithheatingclamp,temperatureprobe,powercable(without

plug)andacarryingcaseasstandard.

1.1 Principle of operation

Aninductionheatercanbecomparedwithatransformerusingtheprincipleofaprimary

coilwithalargenumberofwindingsandasecondarycoilwithafewwindingsona

mutualcore.

Theinput/outputvoltageratioisequaltotheratioofthewindings,whiletheenergy

remainsthesame.InthecaseoftheSKFBearingHeaterTMBH1,theprimarycoil

isconnectedtoahighfrequencypowersupply.Thebearingactsasashort-circuited

single-turnsecondarycoilthroughwhichalowACvoltageowsathighamperage,

thusgeneratingalotofheat.Theheateritselfaswellastheclampremainatambient

temperature.

Duetodifferentphysicalproportionstheinnerringofabearingwillheatupfasterthan

theouterring,thusreducingtheradialinternalclearance.Aslongastherecommended

temperatureof110°Cisnotexceeded,thisdoesnotthreatentodamagethebearing.

Bothgreasedandsealedbearingscanbeheatedwithoutriskofdamage.
