In the market, some of the synchronous pulley factory is currently produced by the timing belt pulley ring riveting is to use the chisel at the junction of riveting a few points (usually in the circle on the four points are distributed), this point Rivets, only by the timing belt pulley on the part of the metal deformation to fix the retaining ring, the solid strength of the pulley is difficult to ensure the reliability of the work.
If the timing belt pulley and the ring is the gap with, it is more difficult to ensure the quality and intensity of riveting belt Pulley in use, the ring is very vulnerable to the side of the extrusion belt, a long squeeze will make the retaining ring It is easy to fall off, this phenomenon will seriously affect the timing belt pulley and the normal operation of the reliability.
