Guangzhou State hung pulley drive features: Advantages pulley drive are: pulley drive can ease the load impact; smooth pulley drive operation, low noise, low vibration; simple pulley drive structure, easy to adjust; pulley drive for the manufacture and installation of precision pulley Unlike strict meshing transmission; pulley drive with overload protection function; two-axis drive from the center of the pulley wide range of adjustment. Disadvantages belt drive are: flexible pulley drive sheave sliding and skidding imports, lower transmission efficiency and can not maintain accurate transmission ratio; shelf sheave, outline dimensions and axial pressure pulley drive to deliver the same circumference greater than the force meshing transmission great. Pulley sheave tested process, according to a certain process to triangulate pulley supplier pulleys for quality inspection following a detailed introduction. Pulley casting quality inspection based on: casting Figure casting process documents, relevant standards and technical conditions of delivery and acceptance of casting. Pulley casting quality and appearance quality castings into internal quality castings. Casting appearance quality including; casting dimensional tolerances, surface roughness of casting, casting weight tolerances, Riser residual amount, casting welding quality and surface defects; intrinsic quality cast including; mechanical properties of casting and chemical properties, chemical composition, microstructure organization, internal defects.
