どなくすことができるし、高動力伝達も可能となる。In order to maintain strength by tightening the belt teeth 1b, which are rubber teeth, as in the past, it is necessary to take deformation and fatigue into account and take a large safety factor, but as mentioned above, it is necessary to take into account deformation and fatigue. In the case of a joint with one or more teeth made of synthetic resin, a safety factor of //3 or less is sufficient, so the joint metal fitting 3',!
: The number of meshing teeth may be 7. In other words, in the case of rubber teeth, 7θθθ x 7 - g, 2θOθ (K9), and in the case of a vertical surface, g, 20θθ However, since the stability of "2" used in -tj is low and impractical, safety will be improved if 7 lead surfaces and 2 rubber teeth are engaged, and the Troubles such as cutting can be almost eliminated, and high power transmission is also possible.
また、鉛面を２〜３個にすれば、安全性の点からゴム歯
に噛合ぜる接合金具６が不要となる。Furthermore, if the number of lead surfaces is reduced to two or three, the joining fittings 6 that mesh with the rubber teeth are not required from the viewpoint of safety.
