The rotation direction of the dual motors of the Pantalla vibrante is usually opposite. Esta rotación en direcciones opuestas puede formar un movimiento alternativo hacia arriba y hacia abajo., lo que ayuda a separar y cribar eficazmente los materiales durante el proceso de cribado., y al mismo tiempo garantiza que la criba vibratoria pueda formar un efecto de cribado eficaz. La siguiente es una explicación detallada de la dirección de rotación de los motores duales de la criba vibratoria.:

Dirección de rotación del motor dual de criba vibratoria

1. La importancia del sentido de rotación de los motores duales de la criba vibratoria.

En la criba vibratoria, La fuerza de excitación generada por la rotación inversa de los dos motores vibratorios compensa la vibración lateral., y la vibración restante en la dirección de avance forma un movimiento lineal de salto. Este modo de movimiento permite que el material avance en línea recta sobre la superficie de la pantalla., logrando así el cribado del material.

Ajustar la fuerza de vibración de un alimentador vibratorio Es crucial para garantizar que funcione de manera eficiente y efectiva.. La fuerza de vibración se puede modificar ajustando los pesos excéntricos o la amplitud y frecuencia de los motores vibratorios..

Los pasos para ajustar la fuerza de vibración de un alimentador vibratorio.

1. Entender el equipo

Consulte el Manual: Antes de realizar cualquier ajuste, Consulte el manual del fabricante para obtener instrucciones específicas y pautas de seguridad relacionadas con su modelo de alimentador vibratorio..

Identificar componentes: Familiarícese con los componentes clave, como los motores vibratorios, pesas excéntricas, y controlar la configuración.

2. Precauciones de seguridad

Apagado: Asegúrese de que el alimentador esté apagado y desconectado de la fuente de alimentación antes de realizar cualquier ajuste..

Equipo de seguridad: Utilice equipo de protección personal adecuado (EPP), como guantes y gafas de seguridad.

3. Ajuste de pesos excéntricos

Localice las pesas excéntricas: Los pesos excéntricos suelen estar montados en los motores vibratorios.. Cada motor suele tener dos pesos.: uno fijo y otro ajustable.

Ajustar el ángulo de las pesas:

Afloje los pernos que sujetan los pesos ajustables..

Gire los pesos ajustables al ángulo deseado para aumentar o disminuir la fuerza de vibración..

Alinee los pesos en ambos motores para garantizar una vibración equilibrada..

Apriete los pernos firmemente después de realizar ajustes..

Instalación angular contact bearings correctly is crucial for ensuring their performance and longevity. There are several methods for installing these bearings, each suitable for different applications and configurations.

Angular contact bearings installation

1. Single Bearing Installation

Mounting Position: Angular contact bearings must be mounted in the correct orientation, with the marked side facing the correct direction to handle axial loads.

Ajuste a presión: The bearing is press-fitted onto the shaft or into the housing. This method often uses a press tool to ensure the bearing is seated properly without applying undue force to the rolling elements.

Thermal Fit: The bearing or housing is heated (expansión térmica) to allow easier fitting. Once cooled, the bearing contracts to form a tight fit.

2. Paired Bearing Installation

Back-to-Back (DB) Arrangement: Bearings are mounted with their back faces together. This configuration can handle axial loads in both directions and provides high rigidity.

Face-to-Face (DF) Arrangement: Bearings are mounted with their front faces together. This setup also handles axial loads in both directions but allows for some misalignment.

Tandem (DT) Arrangement: Bearings are mounted in the same direction. This arrangement is used to handle high axial loads in one direction.

3. Preloading Bearings

Preloading: Preloading is applying a predetermined axial load to the bearing to remove internal clearance. This is essential for high precision and rigidity.

Fixed Preload: Using spacers or shims to set the preload during installation.

Spring Preload: Using springs to maintain a constant preload regardless of temperature changes or other conditions.

4. Assembly Techniques

Pressing Method: Bearings are pressed onto the shaft or into the housing using specialized tools to ensure even pressure and avoid damaging the bearing.

Hydraulic Method: A hydraulic press or a hydraulic nut can be used to install bearings, providing controlled and uniform pressure.

Induction Heating: Induction heaters can expand the bearing seat, allowing the bearing to be slipped onto the shaft or into the housing easily. Once cooled, it creates a tight fit.

UNA cojinete de mesa giratoria, often used in applications requiring precision rotation, such as machine tools and rotary tables, has a specialized structure to support and facilitate smooth rotational movement. Here is an overview of the key components and structure of a rotary table bearing.

1. Bearing Type

Rotary table bearings are typically cross-roller bearings or YRT (Yaw and Roll Table) aspectos, designed to handle axial, radial, y cargas de momento simultáneamente.

2. Componentes y estructura

Anillos interiores y exteriores:

Anillo interior: Mounted on the stationary part of the rotary table, providing the raceway for the rolling elements.

Anillo exterior: Attached to the rotating part of the table, also serving as a raceway for the rolling elements.

Rolling Elements:

Cross-Roller Bearings: Use cylindrical rollers arranged perpendicular to each other in a cross pattern, which allows them to handle high axial and radial loads as well as tilting moments.

YRT Bearings: Comprise an axial needle roller and cage assembly, a radial cylindrical roller, and two axial cylindrical roller and cage assemblies, ensuring high rigidity and precision.

Cage:

Holds and guides the rolling elements, ensuring they remain evenly spaced and reducing friction.

Seals:

Installed on both sides of the bearing to prevent contamination and retain lubrication, enhancing the bearing’s lifespan and performance.

Preload Adjustment:

Many rotary table bearings come with a mechanism to adjust preload, ensuring optimal stiffness and minimizing deflection during operation.

3. Design Features

High Precision: Designed to maintain accurate positioning with minimal deflection, crucial for precision applications like CNC machines and indexing tables.

Alta capacidad de carga: Capable of supporting heavy axial, radial, and moment loads due to the robust design and high number of rolling elements.

The welding process for wind tower construction is critical for ensuring the structural integrity and longevity of the towers. Here is an overview of the main steps involved in the wind tower welding process.

Wind tower welding process

Preparación de materiales

Corte: The steel plates used for wind towers are cut to size using methods like plasma cutting, laser cutting, or oxy-fuel cutting.

Edge Preparation: The edges of the steel plates are beveled to prepare them for welding. This helps ensure strong and consistent welds.

Plate Rolling

Rolling: The cut and prepared steel plates are rolled into cylindrical or conical sections. Rolling is done using plate rolling machines to achieve the desired curvature and diameter.

Soldadura por puntos

Alineación: The rolled plates are aligned and held in place using fixtures.

Soldadura por puntos: Small welds are made at intervals to hold the sections together temporarily before the final welding. Tack welds ensure that the plates remain properly aligned.

Soldadura de paso de raíz

Root Pass: The first pass, or root pass, is performed to join the plates from the inside. This pass is crucial as it forms the foundation of the weld. It is usually done using a welding process like Gas Tungsten Arc Welding (GTAW) or Shielded Metal Arc Welding (SMAW).

Fill and Cap Pass Welding

Filling: Subsequent passes are made to fill the groove created by the beveled edges. Multiple passes are required to fill the joint completely.

Capping: The final pass, known as the cap pass, is done to create a smooth and even surface on the weld. This pass also enhances the weld’s appearance and ensures it meets quality standards.
