Patent ID: 8241159

Claim:
A method for mounting a belt on a first pulley and a second pulley, the first pulley successively having an outer pulley flange, a middle pulley flange, and an inner pulley flange; an outer pulley groove provided between the outer pulley flange and the middle pulley flange, and an inner pulley groove provided between the middle pulley flange and the inner pulley flange, and the second pulley having a pulley groove, the belt having a ring-shape and configured to be stretched in a peripheral direction, the belt being mounted on the first pulley groove by being positioned thereon from the outer side of the outer flange, with respect to the axial direction of the first pulley, comprising: using a guide member and a fixing member to install the belt in the inner pulley groove, wherein the guide member comprises an attaching element and a belt guiding element, the attaching element extending in the peripheral direction of the first pulley, the attaching element having an inner surface configured for being seated in the outer pulley groove of the first pulley and for covering the outer peripheries of the outer pulley flange and the middle pulley flange, the belt guiding element provided approximately at the center of the attaching element with respect to the longitudinal direction thereof and protruding from the attaching element, the guide member having a belt introduction surface configured to face the rotational direction of the first pulley when the guide member is installed on the first pulley, the fixing member configure to fix the guide member on the first pulley and to hold the belt so that the belt is seated in the inner pulley groove of the first pulley; winding the belt around the pulley groove of the second pulley; fitting the guide member in the inner groove of the first pulley; fixing the guide member on the first pulley using the fixing member; seating the belt in the inner pulley groove of the first pulley using the fixing member; positioning the belt in the outer direction with respect to the axial direction of the first pulley, by the guidance of the belt introduction surface of the guide member; and rotating the first pulley in the rotational direction of the first pulley so as to seat the belt in the inner pulley groove of the first pulley.
