Abstract
Abstract An arrangement for coupling a rotary member such as a pulley of V-belt or flat belt to a rotary shaft. A boss is mounted on the rotary shaft so that the rotary shaft will have its one end protruding from the boss. The protruding end is passed through a center hole in the rotary member. A nut is tightened on the end of the rotary shaft protruding from the center hole to tighten the rotary member and the boss and thus couple them together. A plurality of projections are formed on one of the rotary member and the boss and a plurality of cutouts or holes are provided in the other. The projections are inserted in the cutouts or holes to couple the rotary member and the boss together.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
160 words
An arrangement for coupling together a rotary shaft and a rotary member having a center hole therethrough, comprising: a polygonal cross-section part adjacent one end of said shaft and a protruding portion at said end of said shaft and having a threaded portion thereon; a boss having a polygonal cross section-hole extending axially therethrough with a cross-sectional shape complementary to the cross-sectional shape of said part of said shaft, said boss being fixedly mounted on said polygonal cross-section part of said rotary shaft with said protruding end of said rotary shaft extending through said center hole in said rotary member; recess means in said boss; engaging means on said rotary member constituted by a portion of the thickness of said rotary member deformed in a direction toward said boss and having a shape complementary to said recess means and fitting into said recess means; and threaded means engaged on said threaded portion and clamping said rotary member against said boss.
Claim 2
Dependent Claim
