Maharsh Metal Heat Treatment

Shrink Fitting is a technique in which an interference fit is achieved by a relative size change after assembly. This is usually achieved by heating or cooling one component before assembly and allowing it to return to the ambient temperature after assembly, employing the phenomenon of thermal expansion to make a joint. For example, the thermal expansion of a piece of a metallic drainpipe allows a builder to fit the cooler piece to it. As the adjoined pieces reach the same temperature, the joint becomes strained and stronger.

There are a huge number of industries and applications which benefit from shrink fitting or removal. In practice, the methodology employed can vary from a simple manual approach where an operator assembles or disassembles the parts to fully automatic pneumatic or hydraulic press arrangements.

Industries and applications:

 Railway - gearboxes, wheels, transmissions
 Machine tools - lathe gearboxes, mills

 Steel works - roll bearings, roll neck rings
 Power generation - various generator components

 Cement Industries rollers
 Rerolling mill rollers

 Automotive starter rings onto flywheels
 Timing gears to crankshafts

 Motor stators into motor bodies
 Motor shafts into stators

 Removal and re-fitting of a gas turbine impeller
 Removal and re-fitting of hollow bolts in electrical generators

 Assembly of high precision roller bearings
 Shrinkfitting of 2-stroke crankshafts for ship engines
