Principales parámetros técnicos y diseño
1. Diseño compacto: La forma del deslizador está optimizada al extremo dentro del espacio mínimo requerido para la circulación y sellado de la bola, logrando una altura mínima.
2. Equilibrio de rendimiento: utilizando una jaula de alta rigidez y un ángulo de contacto de bola optimizado, la capacidad de carga y la rigidez del sistema se mantienen tanto como sea posible al tiempo que se reduce la altura.
3. Sellado y lubricación: Equipado con sellos de extremo compactos y depósitos de grasa potencialmente integrados, lo que garantiza una buena protección contra el polvo y una lubricación duradera incluso en espacios confinados.
4. Consideraciones de selección:
Confirmar altura máxima: Definir claramente la altura máxima de instalación permitida del equipo; esta es la primera restricción para la selección.
Calcular la carga: bajo la premisa de cumplir con los requisitos de altura, seleccione las especificaciones que cumplan con los requisitos de carga y vida útil.
Elija el tipo de montaje: seleccione el tipo CA (montaje con brida lateral) o el tipo SA (montaje superior) según la estructura del equipo.
Aplicaciones
La serie EGH-CA/SA es el socio perfecto para los siguientes equipos sensibles al espacio:
Fabricación electrónica de precisión: plataformas de movimiento XY para máquinas de colocación SMT, máquinas de envasado de chips y máquinas perforadoras de PCB.
Dispositivos médicos y equipos de laboratorio: analizadores automatizados, secuenciadores de ADN y plataformas de microscopios automáticos.
Pequeña automatización: robots de escritorio, pequeños módulos de motores lineales y mecanismos de guía para máquinas dispensadoras de precisión.
Industria de semiconductores y paneles: robots manipuladores de obleas y ejes lineales con espacio limitado en equipos de inspección de paneles LCD.
La guía lineal de perfil bajo de la serie EGH-CA/SA es la culminación del ingenio de ingeniería en entornos de diseño "con espacio limitado". Esto demuestra que el guiado lineal de alto rendimiento no tiene por qué realizarse necesariamente a costa de ocupar una gran cantidad de espacio. Elegir la serie EGH significa que puede integrar un núcleo de movimiento lineal confiable, preciso y eficiente en su equipo, incluso dentro de estrictas restricciones de tamaño. Es un componente clave para lograr la miniaturización, la integración y el equilibrio del rendimiento en su equipo.

Ball Screw Assembly Workshop
One ball screw shaft matches one ball screw nut. Because each ball screw shaft has a very tiny different tolerance. There are dozens of different ball sizes for different screw shaft. Our ball screw shaft and nut can be interchanged with the Taiwan TBI ball screw shaft and nut very well. |
