Features of synchronous belts?

Characteristics of high profile circular tooth synchronous belt tooth profile compared to conventional circular tooth synchronous belt tooth profile.
Introduction: This kind of high-toothed arc tooth synchronous belt tooth profile has the following main features compared with the traditional arc tooth synchronous belt tooth profile: (1) The height of the synchronous belt tooth is 14.75% larger than that of the traditional STPD arc tooth, which increases the contact area between the belt tooth and the gear tooth as well as the meshing pressure angle, thus improving the same under the condition of the same unit load bearing strength.
This kind of high tooth arc tooth synchronous belt tooth profile and the traditional arc tooth synchronous belt tooth profile compared with the following main features: (1) synchronous belt tooth profile and the traditional arc tooth synchronous belt tooth profile have the following main features.
(1) synchronous belt tooth height than the traditional STPD arc tooth height is 14.75% larger, increasing the contact area between the belt teeth and gear teeth and meshing pressure angle, thus increasing the synchronous belt load carrying capacity under the condition of the unit load carrying strength remains unchanged.
(2) The height of the teeth of the synchronous belt is 6.06% larger than the height of the gear teeth, to reduce the pressure between the groove of the belt teeth and the top of the gear teeth, improve the wear condition between the teeth of the belt and the stress condition of the bearing layer, and increase the life of the belt.
(3) The four grooves on the top of the teeth of the synchronous belt can remove the air when the belt meshes with the wheel and reduce the noise, and at the same time, the grooves can also deform the top of the teeth and form the elastic top of the teeth, which can reduce the impact of meshing and improve the meshing condition.
Conclusion
(1) Through calculation and simulation, this paper analyzed and compared the design profile of the new high-tooth synchronous belt with the belt wheel tooth profile according to the belt wheel tooth profile (i.e., the belt's calculated tooth profile), and found that one of the matches is very ideal, and the design profile of the belt wheel with the belt tooth profile according to the belt's tooth profile (i.e., the belt wheel's calculated tooth profile) also coincides with the design of the belt wheel tooth profile, which indicates that the new high-tooth synchronous belt with the belt wheel's designed tooth profile is reasonable, and can achieve the close fit during transmission. This shows that the design profile of the new high-tooth synchronous belt and the pulley is reasonable and can achieve a close fit during transmission.
(2) From the drawing of the total reel tooth profile can be seen, the belt mold hob and the belt wheel hob tooth profile of the transition curve do not appear sharp corners, and the eye tooth profile smooth and continuous, the processing process to avoid the phenomenon of ten involved or root cut.
(3) Through the dynamic simulation of the transmission process can be visualized to qualitatively analyze the synchronous belt drive incomplete meshing process of meshing ten.

  • Rubber Wide - Angle Belt
    Rubber Wide - Angle Belt
    The wide-angle belt is a new type of industrial transmission belt developed on the basis of the general industrial V-belt technology.
    They are all driven by the friction diagram on both sides of the belt. The wedge angle of the general V-belt is 40° and the wedge angle
    of the wide-angle transmission belt is 60°.
    According to the principle of transmission dynamics, as the wedge angle of the wide-angle belt increases, the area supported by the
    two transmission sides naturally increases, thus giving rise to the following advantages over the general V-belt:
    1. The load of the wide-angle belt is evenly distributed and the wear resistance is improved.
    2. The contact area between the belt and the pulley increases and the transmission force is increased.
    3. It improves the concave deformation of the drive belt core and strengthens the drive characteristics.
    4. After the wide-angle belt is installed and used, the problem of belt tension drop is improved.
    It is the above-mentioned advantages of the wide-angle belt that are widely used and affirmed by the precision machinery industry.

  • Rubber Conveyor Belt
    Rubber Conveyor Belt
    The conveyor belt is composed of surface adhesive, core, and layer glue. In addition, a layer of buffer cloth can be added to the use of high drop impact to make it more impact-resistant.

    The surface adhesive
    With natural rubber and synthetic rubber as raw materials and in order to enhance wear resistance, crack resistance, aging resistance, and other properties, the surface adhesive has various characteristics such as wear resistance, cutting resistance, heat resistance, flame resistance, cold resistance, acid and alkali resistance, oil resistance, static electricity resistance and so on.
    Cloth layer core
    The cloth layer is composed of natural fiber or chemical fiber alone or a combination of the two, has the same quality after single-step treatment by a mature process, And has good adhesion with rubber.
    The adhesive layer
    The adhesive layer is very important for the adhesive force between the layers of the core of the conveyor belt that is repeatedly flexed. Especially for high-tension conveyor belts, a layer of adhesive with less buckling stress and less fatigue due to internal stress must be used.
    Specifications and models can be customized according to customer requirements, with a thickness ranging from 2.0 mm to 8.0 mm.
