Abstract (en)
[origin: JPH03252A] PURPOSE: To couple components in an accuracy correspondingly by a frictional coupling by remarkably increasing a frictional force at a predetermined clamping force by providing several frictional members superposed in a thin plate state. CONSTITUTION: To effectively frictionally couple an inner shaft 1 to a segment 2 provided at an outside cylinder, several frictional members 7 of a disc clutch shape are fixed at an interval in a package state, for example, by a screw 9 with a surface B of the segment radially extended as near as a sidewall 4. A package formed complementarily of a frictional member 10 is fixed, for example, by a screw 12 similarly to a radially extended surface of a support base 11 directly coupled to a bearing journal 3 or the shaft 1. In this case, a frictional member 7 superposed with an intermediate layer of the same thickness and a frictional member 10 superposed similarly with such an intermediate layer are engaged with one another and superposed in a specific range 13.
