DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a V-belt mounting apparatus and a mounting method provided in, for example, a step driving mechanism of an escalator or another power transmission mechanism.

[0002]

2. Description of the Related Art Conventionally, as described in, for example, Japanese Patent Application Laid-Open No. 9-242834, an operation handle is mounted on an end face of a pulley of a power transmission mechanism, and a rake piece and a side guide piece are inserted into a belt groove of the pulley. A V-belt mounting device has been proposed in which, after being inserted and brought into contact with the V-belt, the pulley is rotated by driving the operation handle, and the V-belt is pushed toward the adjacent belt groove by the side guide piece. ing.

[0003]

In the above-described conventional V-belt mounting apparatus, the rake piece is inserted into the belt groove to hold the rake piece in the belt groove. The operation is troublesome, and it is necessary to perform this troublesome operation a plurality of times for each V-belt. In addition, since the rake piece is not fixed to the pulley, the rake piece may be pushed by the pulley and slip down, and there is also a problem that stability is hindered when the V-belt is attached.

The present invention has been made in view of such a situation in the prior art, and a first object of the present invention is to provide a simple structure, good operability, and easy even for an unskilled worker. An object of the present invention is to provide a V-belt mounting device capable of mounting a plurality of V-belts between pulleys.

It is a second object of the present invention to provide a method of mounting a plurality of V-belts between pulleys in a relatively short time.

[0006]

In order to achieve the first object, according to the first aspect of the present invention, a plurality of V-belts are mounted between a plurality of pulleys provided in a power transmission mechanism. A V-belt mounting device, comprising: a base body detachably attached to the pulley; and at least one belt moving means detachably coupled to the base body to move the V-belt in an axial direction of the pulley. A plurality of locking claws, each of which is locked to a belt groove of the pulley, a clamp member for attaching the base body to the pulley by adjusting a distance between the locking claws; A handle for driving the base body, wherein the belt transition means is formed by cutting a predetermined arc angle from the ring body, and a tip of the side of the V-belt is formed. Are a configuration having an inclined surface that engages the.

In the invention according to the first aspect of the present invention, a base member having a belt transfer means connected in advance is attached to a pulley, and one V-belt is provided at the tip end of a plurality of belt grooves of the pulley. And the side surface of the V-belt is engaged with the inclined surface of the tip of the belt shifting means. In this state, the handle is operated to rotate the base member and the belt shifting means in the rotation direction of the pulley. As a result, the side surface of the V-belt is pressed by the inclined surface of the leading end of the belt moving means, so that the V-belt moves inward from the leading end side of the belt groove and is mounted in a predetermined belt groove. Next, the other V-belts are attached to the predetermined belt grooves in the same manner. As a result, a V-belt mounting device having a simple configuration, good operability, and capable of easily mounting a plurality of V-belts between pulleys even by an unskilled worker is obtained.

In order to achieve the second object, the invention according to claim 3 of the present invention provides a method of mounting a plurality of V-belts between a plurality of pulleys provided in a power transmission mechanism. In the above, when the V-belt is hung between the plurality of pulleys, a plurality of belt moving means are connected to a base body, and the base body is attached to one of the pulleys, and one V-shaped belt is moved by the plurality of belt moving means. By shifting the belt in the axial direction of the pulley, the single V-belt is hooked on a predetermined belt groove of the pulley, and each time the V-belt is completely mounted, the plurality of belt shifting means are removed one by one. , And the V-belt are sequentially mounted.

In the invention according to the third aspect of the present invention, a plurality of belt transfer means are removed one by one each time one V-belt is finished hanging on a predetermined belt groove of the pulley. When the next one V-belt is hooked on the corresponding predetermined belt groove, there is no need to close the belt groove with the belt transfer means, and no trouble occurs. Since the transition can be made smoothly to the belt groove, a plurality of V-belts can be mounted between the pulleys in a relatively short time.
