2. Description of the Related Art In currently available compact disc players, a table loading portion and gears used for table loading are the main constituents. The table loading portion has a belt tooth unit. A drive mechanism composed of a timing belt having a very small belt tooth with a pitch of 1.0 to 2.0 mm and a timing pulley meshing with the timing belt, or a coreless rubber square belt having a square belt cross-sectional shape. A drive mechanism including a V pulley having a V groove into which a corner portion of the square belt fits is often used.

DISCLOSURE OF THE INVENTION Problem to be Solved by the Invention Audio equipment such as a compact disc player is extremely disliked by annoying noise. When the belt in the drive mechanism is a timing belt, noise is increased due to the meshing of the teeth of the belt and the timing pulley, and the use of this timing belt has many problems in audio equipment. On the other hand, when the used belt is a rubber square belt, the belt is a coreless body, so that the power transmission ability is unstable and there is a problem in terms of the life of the belt. Further, in the case where the belt is the conventional V-ribbed belt, since the rib height of the belt is large and the rigidity is large, the transmission force in the small pulley becomes small and slipping is observed.

The present invention has been made in view of the problems of the above-described conventional belt. By partially modifying the rib shape of the V-ribbed belt, noise is prevented and sufficient transmission is achieved even if the pulley diameter is small. The purpose is to provide a V-ribbed belt having the capability.

In order to achieve this object, this invention has the following structure. That is, in a V-ribbed belt in which a tension rope is embedded in a spiral shape in a belt body and a plurality of truncated V ribs extending in the belt circumferential direction are integrally formed with the belt body on the lower surface of the belt body, a rib of the V rib is formed. The angle (θ) is 50 ° to 60
The V-ribbed belt is characterized in that the V-rib pitch (P) is set in a minimum range of 0.5 to 1.5 mm. The belt main body and the truncated V rib portion are both formed of urethane elastomer, and particularly the V rib portion has a Shore A hardness of 50 ° to 90 °. Further, the height of the V-rib portion is set in the range of 0.3 to 0.6 mm in order to reduce the rigidity while maintaining a certain transmission force.

In the V-ribbed belt according to the present invention, when the compact disc table is put in or taken out, there is no interference between the belt teeth and the pulley teeth as in the conventional timing belt, so that the table can be put in and taken out very quietly. Further, by making the rib pitch of the truncated V-ribs extremely small and setting the rib height within a certain range, the contact area with the pulley becomes large, and the belt does not slip and the durability is sufficiently cleared.

FIG. 1 shows a V-ribbed belt according to the present invention, in which the main body of the V-ribbed belt 1 is made of urethane resin, and a flat belt-shaped belt main body 2 has polyester, aramid (commercial products) along the circumferential direction of the belt. Name: Kevlar), nylon, glass fiber, etc. A low tensile strength rope 3 of high tensile strength is embedded in a spiral shape, and the inner peripheral surface of the belt body 2 is made of the same material as the belt body and hard. The shore A is in the range of 50 to 90 ° and a plurality of truncated V-ribs 4 extending in the belt circumferential direction are integrally formed with the belt main body 2 while maintaining the parallel state.

[0010] The feature of this invention is indeed to this truncated form V ribs 4, the angle (theta) of this truncated form V ribs 4 is set in a range of 50 ° to 60 °, further pitch of V-ribs 4 (P) is set to a minimum pitch of 0.5 to 1.5 mm. The height (t) of these V ribs 4 is set in the range of 0.3 to 0.6 mm.
Correspondingly, a plurality of V-grooves 7 into which the truncated V-ribs 4 of the belt 1 are fitted are formed at a small pitch on the V-ribbed pulley 6 on which the V-ribbed belt 1 is mounted. (Fig. 2)

When the rib angle (θ) of the V-ribbed belt is 61 ° or more, the wedge effect is reduced and the belt transmission force is reduced. If the angle is less than 40 °, the rigidity becomes large, and if the diameter of the pulley is small, the bending property becomes poor and the transmission force becomes small. Especially, the rib angle is as small as 8mm.
If (θ) is less than 50 °, the flexibility will deteriorate and the transmission
The power becomes smaller. Next, if the rib pitch (P) of the V-ribbed belt is 1.6 mm or more, the belt width becomes too wide when two ribs are required, and the belt is unsuitable for the compact disc table drive device 14 which is aimed at downsizing. On the other hand, if the rib pitch (P) is less than 0.5 mm, there is no functional problem as a belt, but the manufacturing process capability becomes a problem. Further, the height ( t ) of the truncated V rib 4 is 0.
If the thickness is 7 mm or more, the belt thickness becomes too large, the rigidity becomes large, and the flexibility is deteriorated. On the other hand, if the height of the V-rib 4 is less than 0.3 mm, the contact area becomes small, and the problem that the belt easily comes off the pulley becomes remarkable.

FIG. 3 shows that the drive pulley 6A has a small pulley diameter of 8Φ and the V rib height (t) of the V-ribbed belt according to the present invention is changed to 0.4 mm and 0.5 mm, and the conventional V-ribbed belt ( The V-rib height is 0.8 mm) and the results of testing the relationship between the load applied to the belt and the slip ratio are shown in the graph. The rib angle of each belt was 60 °, the rib pitch was 1.0 mm, and the hardness of the V rib was 80 °. As is clear from the test results, the slip ratio decreases as the rib height decreases. Incidentally, the minimum rib pitch of the conventional V-ribbed belt is 1.60 mm for the H type, the rib height is 1.0 mm, and the rib angle is set to 40 °.

When the V-ribbed belt according to the present invention is used in a compact disc table vending machine, more specifically in a compact disc table drive unit, smooth loading of the table is not hindered, and it has been widely used conventionally. The timing belt drive unit, which was widely used in the compact disc table drive field, has a noise level of 4%.
Although it was 3 dB, in the V-ribbed belt drive unit in which the present invention is implemented, the noise is reduced by 36 dB and about 16%, and a desirable effect as a noise mechanism of a hearing device in which acoustic elements are of the utmost importance is exhibited. In addition, compared with the conventional belt, the belt of the present invention has an effect of having a small slip ratio and a sufficient transmission ability even with a small pulley diameter of 8 mm .
