\n

El reductor rotativo del\u00a0\u00a0cami\u00f3n bomba de hormig\u00f3n<\/strong><\/a>\u00a0 Se llena con aceite de transmisi\u00f3n API GL4 con un grado de viscosidad SAE 90 (de f\u00e1brica se llena con aceite para engranajes Shell VG150). Se a\u00f1aden diferentes cantidades de aceite para engranajes seg\u00fan los distintos tipos de reductores (unos 8 litros para Bruvini y unos 4 litros para Comman). Es necesario cambiarlo cada 500 horas de bombeo o cada medio a\u00f1o.<\/p>\n

Inspecci\u00f3n diaria del reductor rotativo<\/h2>\n

1. Limpia a diario y a tiempo la arena y la grava del mecanismo del cojinete de giro y comprueba si los pernos del cojinete de giro y los pernos de fijaci\u00f3n del reductor est\u00e1n sueltos o rotos. Si se detectan pernos sueltos o rotos, deben apretarse o sustituirse;<\/p>\n

\"1\"<\/p>\n

2. Abre la tapa superior; podr\u00e1s ver los engranajes del reductor y el anillo dentado de la mesa giratoria. Procura limpiar con regularidad el mortero y la suciedad de los engranajes que se engranan entre s\u00ed, y aplica mantequilla en el reductor \u2014es decir, debajo del pi\u00f1\u00f3n\u2014 para evitar que entre agua en el reductor;<\/p>\n

\"2\"<\/p>\n

3. Comprueba cada mes la calidad y el nivel de aceite del reductor;<\/p>\n

4. Cambia el aceite de la caja de cambios cada 500 horas de funcionamiento; o bien, c\u00e1mbialo cada invierno antes de que bajen las temperaturas por debajo de cero;<\/p>\n

5. En el caso de los reductores con m\u00e1s de 500 horas de funcionamiento, se debe comprobar el juego axial del reductor una vez al mes (Nota: las 800 horas constituyen el periodo de mayor incidencia de aver\u00edas);<\/p>\n

6. El m\u00e9todo concreto de inspecci\u00f3n peri\u00f3dica es el siguiente:<\/p>\n

Retira la cubierta superior y utiliza la varilla de presi\u00f3n para hacer palanca y sacar el engranaje peque\u00f1o del reductor. Si hay holgura (aunque sea de solo 1 mm), significa que el rodamiento del reductor se ha da\u00f1ado y hay que detener la m\u00e1quina y sustituirlo inmediatamente; los modelos de los dos rodamientos son: 32220 y 30217. Lo mejor es pedir a los clientes que compren rodamientos importados. En cuanto a las marcas nacionales, elija rodamientos Wafangdian o Harbin.<\/p>\n

Las consecuencias negativas de no revisar a tiempo el reductor rotativo<\/h2>\n

1. Cuando el cojinete del reductor se desgasta, el engranaje tiende a aflojarse y la torreta de control no se puede bloquear, lo que da lugar a accidentes de seguridad.<\/p>\n

2. Si los pernos de la torreta est\u00e1n sueltos o rotos y no se inspeccionan a tiempo, el anillo dentado quedar\u00e1 suelto y no encajar\u00e1 correctamente, lo que provocar\u00e1 que la rotaci\u00f3n sea dif\u00edcil y aumente el riesgo de que se produzcan aver\u00edas graves.<\/p>\n

3. Si llega el invierno y no se revisa la junta del reductor, el aceite del engranaje se mezclar\u00e1 con el agua y la carcasa del reductor se congelar\u00e1 y se agrietar\u00e1.<\/p>\n

4. Aumentar los costes de uso para los clientes;<\/p>\n

Pasos para el mantenimiento del reductor rotativo<\/h2>\n

1. Deja que el reductor funcione durante un rato. Cuando la temperatura alcance unos 30 grados, desenrosca el tap\u00f3n de drenaje de aceite del reductor, vac\u00eda el aceite usado y vuelve a apretar el tap\u00f3n.<\/p>\n

2. Limpia la zona alrededor del reductor con un pa\u00f1o;<\/p>\n

3. Desatornilla la tapa de ventilaci\u00f3n y el tap\u00f3n de nivel de aceite, y a\u00f1ade aceite lubricante a trav\u00e9s del orificio de llenado hasta que salga aceite limpio por el orificio de nivel de aceite;<\/p>\n

\"3\"<\/p>\n

Advertencia:<\/strong><\/p>\n

Antes de que lleguen las heladas invernales, sustituya el aceite lubricante del interior; de lo contrario, el reductor podr\u00eda congelarse y agrietarse.<\/strong><\/p>\n
