このような歯付ペル）ａは、チェーン、ギヤ等の伝達手
段に比して、一般に低騒音となっているが、高速駆動に
なるき、上記伝達手段と同様に無視できない騒音が発生
するという問題点があった。As shown in Fig. 2, in the conventional toothed belt (a), square prism-shaped teeth C in a direction perpendicular to the belt longitudinal direction, that is, in the belt width direction, are arranged at equal intervals around the entire circumference of the belt, as shown in Fig. 2. 0 Such toothed pels a) generally have lower noise than transmission means such as chains and gears, but when driving at high speed, Similarly, there was a problem in that non-negligible noise was generated.
そこで、発明者は、前記騒音発生の一因子として歯付ベ
ルトの歯元とプーリの歯先との衝突時に発生する打撃音
が考えられることから、歯付ベルトの歯元すなわち歯部
と歯部との間に、クッション作用を呈する突部を設ける
ことによって、衝撃時における打撃音を吸収緩和し、駆
動を低減することができる歯付ベルトおよび歯付ベルト
駆動装置を開発するに至ったのである。Therefore, since the impact sound generated when the tooth root of the toothed belt collides with the tooth tip of the pulley is considered to be one of the factors that generate the noise, the inventor proposed that the tooth root of the toothed belt, that is, the tooth portion By providing a protrusion that exhibits a cushioning effect between the belt and the belt, the company has developed a toothed belt and a toothed belt drive device that can absorb and soften the impact sound caused by an impact and reduce the drive force. .
本発明は、駆動時、特に高速駆動時における騒音が著し
く低減される歯付ベルトおよび歯付ベルト駆動装置を提
供することを主′目的とする。The main object of the present invention is to provide a toothed belt and a toothed belt drive device in which noise during driving, particularly during high-speed driving, is significantly reduced.
以下、本発明の構成を、実施例について、図面に沿って
説明する。DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below with reference to embodiments with reference to the drawings.

高さとなっている。すなわち、突部４の高さは歯部３の
高さの５％〜３０％になるように形成されている。1 to 3, reference numeral 1 denotes an endless toothed belt, in which toothed portions 3 in the belt width direction are arranged on a belt base band 2 at equal intervals over the entire circumference of the belt. A protrusion 4 is provided at a substantially intermediate position between 3.3 and 3. This protrusion 4 is formed over the entire width of the belt base band 2 like the toothed portion 3, but its height is lower than that of the toothed portion 3. That is, the height of the protrusion 4 is formed to be 5% to 30% of the height of the toothed portion 3.

ることになるので、騒音の低減が図られる。The depth of this groove 7 is 0 to 10θ equal to the height of the protrusion 4.
%, so that when the toothed belt 1 and the pulley 5 are in mesh with each other, the protrusion 4 supports the shaft (not shown) of the toothed belt 1, making the entire belt into an arc shape. Since the protrusion 4 bears part of the load that the tooth 3 receives, noise can be reduced.

た。(Experiment, 2) Using the toothed belt according to the present invention used in (Experiment/),
The depth of the groove 7 relative to the height of the protrusion 4 in the pulleys 11 and 12 was varied, and the effect of this on noise was investigated.

The contact state is the same as that shown in FIG. The belt running conditions were a belt speed of 10 rn/sea and a belt tension of 20 Kq.

命の低下に通ずるので好ましくない。From Figure 7, which shows the results of (Experiment 2), the noise reduction effect is obtained when the groove depth ratio (=depth of the groove to the protrusion/height of the protrusion x/θO) is 40% or more. If there is, you know it's the best thing. However, if the groove depth ratio exceeds 700%, the portion of the belt tooth tip that comes into contact with the pulley tooth tip will decrease, and the local load burden on that portion will increase, leading to a reduction in belt life, which is undesirable.
したがって、前記凹溝深さ率は、１０％〜１００％の範
囲にあることが望ましい。Therefore, it is desirable that the groove depth ratio is in a range of 10% to 100%.

た効果を有する。In addition, even when no groove is provided for the protrusion, that is, when the groove depth ratio is θ%, the sound pressure level is about jdB lower than in the conventional case, which is advantageous in terms of noise reduction. According to the present invention, as described above, the protrusion is provided between the teeth, so that when the toothed belt meshes with the pulley, the protrusion has a cushioning effect. and reduce noise.
In particular, the depth of the groove into which the protrusion fits is determined by the height of the protrusion.
% to 10θ%, the noise is significantly reduced and does not pose much of a problem even during high-speed driving, which is an excellent practical effect.
