Description

V-belt effective diameter measuring device

The present invention relates to a V-belt effective diameter measuring device that measures the effective diameter of a V belt that is disposed in the engine room of a car and transmits rotational power. In particular, when the 25-kgf tension is applied to the V-belt, the V-belt is measured. The present invention relates to a V-belt effective diameter measuring apparatus that can easily determine the presence or absence of a defect.

In general, the V-belt, which is disposed in the engine room of a car and transmits rotational power, is repeatedly subjected to repeated bending movements because of large fluctuations in rotational speed or a large load, and a small pulley diameter.

As such, the V-belt is generally used to cover the outer circumference of the synthetic rubber with a cover cloth by inserting a rope made of tetron in the center of the synthetic rubber to prevent the elongation of the effective diameter.

In other words, the V-belt, which is installed in the engine room of a car and transmits rotational power, has to have a proper effective diameter when the tension of 25 Kgf is applied to perform the function.

Like this, when the 25Kgf tension is applied, the V-belt that has to have the proper effective diameter does not have the equipment to measure the effective diameter before installing it in the engine room. When the V-belt was installed in the engine room, the mounted V-belt was removed from the engine room, and another V-belt was installed and the tension thereof was checked.

That is, conventionally, there is a problem that the effective diameter can not be checked when the tension of 25Kgf is applied before the V belt is mounted in the engine room.

The present invention has been made in view of the above-described problems, and an object of the present invention is to measure the effective diameter at a tension of 25 Kgf before mounting the V belt in the engine room, and to detect a defective V belt having no predetermined effective diameter. An effective diameter measuring apparatus for a V-belt is provided.

In order to achieve the above object, the effective diameter measuring apparatus for a V belt according to the present invention includes a base member having a fixed pulley fixed to an upper surface thereof so that a part of the V belt is caught, and a V belt fastened to a fixed pulley fixed to the base member. A transfer member disposed on the upper portion of the base member so that the other end is caught, and a transfer member which is interlocked with the transfer pulley so as to apply tension to the V-belt caught on the transfer pulley and the fixed pulley and the transfer pulley is fixed on the upper portion And, the conveying means for controlling the conveying member to convey the conveying member and the conveying means consisting of a screw and handle, and the V belt wound around the conveying pulley conveyed by the control of the conveying means of the base member Tension measuring means mounted on one side of the upper surface, and the image to measure the effective diameter of the V belt is measured by the tension measuring means It characterized in that the effective diameter made of a measuring means fixed to the top surface of the base member.

According to the effective diameter measuring device of the V-belt according to the present invention, the V-belt is put on the feed pulley and the fixed pulley, and then the feed pulley is transferred to the conveying means so that the V-belt takes a tension of 25 Kgf. By measuring the effective diameter of the V-belt it is possible to easily determine whether or not.

Hereinafter, with reference to the accompanying drawings an embodiment of the effective diameter measuring apparatus of the V belt according to the present invention will be described in detail.

1 is a perspective view showing an effective diameter measuring apparatus of the V-belt applied to the present invention.

In Fig. 1, reference numeral 1 denotes a base member having a fixed pulley 2 fixed to an upper surface thereof so that a part of the V belt mounted on an engine room of an automobile is caught, so that the other end of the V belt is caught in an opposite direction of the upper portion thereof. The feed pulley 3 is mounted.

In addition, the transfer pulley (3) is reciprocated so as to apply tension to the V-belt caught on the transfer pulley (3) and the fixed pulley (2) transfer member (4) is conveyed in conjunction with the transfer pulley (3) It is fixed to the upper part of.

In addition, an indicator needle 5 is attached to one side of the transfer member 4 to instruct the scale of the effective diameter measuring means described later so that the effective diameter of the V belt can be easily known.

On the other hand, in the figure (10) is a conveying means consisting of a screw 11, a handle 12, a fixing member 13, etc. to control the conveying of the conveying member 4, the fixing member 13 and the Between the fixed member 13, the guide member 14 for guiding the transfer of the transfer member 4 is mounted so that the transfer member 4 is transferred without being flown.

In addition, at a predetermined position on the upper surface of the base member 1, the tension measuring means 20 so as to measure the tension of the V-belt wound on the conveying pulley 3 conveyed by the control of the conveying means 10. ) Is installed.

In addition, an effective diameter measuring means 30 is attached to the upper surface of the base member 1 so as to measure the effective diameter of the V belt in which the tension is measured by the tension measuring means 20.

Next, the effect of the effective diameter measuring apparatus of the V belt according to the present invention configured as described above will be described.

First, one end of the V-belt to be measured is wound on the fixing pulley 2, the other end of the V-belt is wound on the conveying pulley 3, and the handle 12 of the conveying means 10 is turned, and the screw 11 ) Is rotated so that the conveying member 4 is conveyed in the direction of arrow A shown in FIG.

In addition, when the conveying member 4 is conveyed in the direction of the arrow A under the control of the conveying means 10, the conveying pulley 3 fixed to the upper portion of the conveying member 4 is also conveyed with the conveying member 4. Interlocked with each other, it is conveyed in the direction of arrow A.

In addition, when the transfer pulley 3 is transferred in the direction of arrow A, tension is applied to the V-belt wound around the fixed pulley 2 and the transfer pulley 3, and the tension applied to the V-belt is the tension measuring means. Appears at (20).

At this time, the operator transfers the transfer pulley 3 until the tension of 25Kgf is applied to the V-belt, and then reads the dimension indicated by the indicator needle 5 mounted on the transfer member 4 to determine the effective diameter of the V-belt. You will know.

In other words, the operator can easily find out the effective diameter of the V-belt when the V-belt is subjected to a tension of 25Kgf, it is possible to extract the defective V-belt rather than the appropriate dimensions.

As described above, according to the effective diameter measuring device of the V-belt, the V-belt is applied to the conveying means by hooking the V-belt to the conveying pulley and the fixed pulley so that the V-belt takes a tension of 25 Kgf. By measuring the effective diameter of the V-belt, there is a very practical effect that it is possible to easily determine whether or not the V-belt is defective.
