Abstract

PURPOSE: To decrease shrinkage allowance of a shrinkage fit assembly structure of a composite product by constituting same such that a recess formed in the inner peripheral surface of a sleeve has a cross section of an arc of a large radius so as to decrease concentration of stress to the assembly.
CONSTITUTION: A thick sleeve 2 to be shrinkage fitted on a shaft 1 has formed at the inner peripheral surface thereof an axial recess 6 of an arcuate cross sectional shape of a larger radius R2. Meanwhile, the shaft 1 of a radius R1 has formed on the outer peripheral surface thereof an axial recess 7 of a rectangular cross sectional shape in a position confronting the recess 6 of the sleeve 2. In a gap formed by the two recesses 6, 7 a key 5 having a cross section corresponding to the shape of the gap is inserted to engage the sleeve 2 and the shaft 1 with each other. In the shrinkage fit assembly structure wherein the recess 6 formed in the inner peripheral surface of the sleeve 2 is formed into an arc of a certain large radius, the key 5 provides an effective means for transmitting torque from the shaft 1 to the sleeve 2 and prevents concentration of stress to the assembly.
