.~.~.~ By temperature differential (e.g., shrink fit)
DEFINITION
Classification: 29/447
By temperature differential (e.g., shrink fit):
(under subclass 446) Process in which the tension or compression is effected by changing a dimension of one of the parts relative to the other part by creating a temperature variation between the parts.
(1) Note. Included in this subclass is a process of fastening parts by means of a shrink fit for example, heating to expand a rim followed by assembling the rim over a wheel and allowing the rim to cool and shrink into gripping assembly with the wheel.
(2) Note. "Expansion Fitting", as by cooling to shrink and prestress is included herein.
