Abstract

PURPOSE: To rapidly carry out installation and removal of shear keys to a casing of complicated shape by using cylindrical rollers as shear keys of dropping-in type.
CONSTITUTION: As shown in the drawings, a top cover 5 and a bottom cover 6 are fitted to the upper and lower portions of a casing 3, respecitvely, through which sear keys 1 are installed or removed. The installation of the shear keys 1 can be made by dropping the cylindrical type shear keys 1 into a groove formed in an end plate 2 through a top opening from which the top cover 5 is removed, while the removal of them can be made through a bottom opening from which the bottom cover 6 is detached. Even if the casing 3 has complicated shape such as, for example, a cocoon like shape as shown in the drawings, the installation and the removal of the shear keys 1 can be easily made. As since cylindrical rollers are used as the shear keys 1 of dropping-in type, the installation and the removal of the shear keys 1 can be rapidly carried out to the casing of complicated shape.
