US 9,038,798 B2 · Shaft connection structure and shaft connection method

Abstract

A shaft connection structure connects a pair of rotating shafts by a fit between a pair of spline shafts, wherein the pair of rotating shafts are provided with corresponding ones of the pair of spline shafts. The shaft connection structure includes a shaft connection assist device. The shaft connection assist device includes a centering ring and centering pins. The centering ring is arranged outside of a first one of the spline shafts and coaxially with the first spline shaft. The centering pins are provided outside of a second one of the spline shafts. The centering pins engage with an outer peripheral surface of the centering ring and bring a shaft axis of the first spline shaft and a shaft axis of the second spline shaft into a range enabling the fit therebetween.

A shaft connection method, comprising:

attaching a first spline shaft to a rotating shaft of a product under test;
arranging a centering ring outside of the first spline shaft and coaxially with the first spline shaft;
attaching a second spline shaft to a rotating shaft of a testing device for testing the product under test;
attaching a plurality of centering pins to a shaft support member to which the second spline shaft is attached, in a manner to allow axial movement of the centering pins by a pin drive member;
allowing axial movement of the shaft support member by a shaft support member drive member;
causing by the pin drive member the plurality of centering pins to travel toward the product under test, to engage with an outer peripheral surface of the centering ring, and to bring a shaft axis of the first spline shaft and a shaft axis of the second spline shaft into a range enabling a fit therebetween;
and thereafter
causing the second spline shaft to travel forward and cause the fit between the first spline shaft and the second spline shaft.
