Seleccionar un freno industrial no se trata solo de elegir un modelo que \"parezca lo suficientemente grande\". Si subdimensionas el par, la carga se deslizar\u00e1 o caer\u00e1. Si lo sobredimensionas, romper\u00e1s ejes, desgastar\u00e1s dientes de engranajes y da\u00f1ar\u00e1s estructuras con golpes de parada brutales.<\/p>\n\n\n\n
This article provides the engineering formulas<\/strong> y safety factors (K-factors)<\/strong> needed to size brakes correctly for hoists, travel drives, and belt conveyors. We will connect these calculations to our product lines, such as YWZ13 drum brakes<\/strong><\/a> for general crane duty and SH fail-safe disc brakes<\/strong><\/a> for high-energy holding.<\/p>\n\n\n\n Infograf\u00eda que muestra las entradas de la f\u00f3rmula: Potencia del motor (P), Velocidad (n) y Factor de Seguridad (K).<\/p>\n\n\n\n Comienza con el par est\u00e1tico requerido para mantener la potencia nominal del motor. La ecuaci\u00f3n que rige es:<\/p>\n\n\n$T_{est\u00e1tico} = \\frac{9550 \\times P}{n}$<\/span>\n\n\n\n Ejemplo:<\/strong> A 45 kW motor running at 750 rpm (common for crane hoists):<\/p>\n\n\n$T_{est\u00e1tico} = \\frac{9550 \\times 45}{750} = 573\\ \\text{N\u00b7m}$<\/span>\n\n\n\n Note: This is just to hold the motor against its own rating. It does not account for gravity, safety, or dynamic stopping.<\/em><\/p>\n\n\n\n You never select a brake at $T_{static}$. You apply a Service Factor ($K$)<\/strong> based on the risk and application type.<\/p>\n\n\n$T_{freno} \\ge T_{est\u00e1tico} \\times K$<\/span>\n\n\n\n1) La f\u00f3rmula fundamental del par<\/h2>\n\n\n\n
