Cadena de la hoja

Leaf chains consist of pins and plates only and therefore are greater in power than roller chains. They’re appropriate for tasks like hoisting and pulling. Leaf chains conform to ANSI and also have two varieties: AL and BL.
Forma AL
To the use that static load is utilized with very little concern of sporting.
Estilo BL
For your use that put on resistance is needed due to the fact affect load is applied.
Elección de cadenas de hojas
The chain dimension is picked in accordance on the following formula:
¿Tensión de actuación? ¨ ¢ Factor de servicio¡§Q Tensión máxima admisible Notas:
1. Acting stress contains the dead excess weight on the chain, the excess weight on the attachments and inertia.
2. In the event the chain pace exceeds thirty m/min, use a roller chain.
Diámetro mínimo de la polea: SD = ¿paso de cadena? ¨ ¢ 5
Minimum width involving flanges: L = General length of pin?¨¢1.05
? Si se ofrecen pines de conexión: L¡§R2L1? ¨ ¢ 1.05
F.D = S.D + Optimum website link plate height (H) Note:?If dimension H exceeds 25.4,
F.D = S.D + 25.4 is usually adopted because the minimum flange outer diameter.
Inspección periódica y directrices para sustitutos.
Make sure you perform periodical inspection and lubrication to verify security and prolong chain existence. Issues and instructions for alternative are outlined in the following.
Issue:Circumferential dress in of plate
Solution:Exchange the chain if wear reduction gets five % of H.
Dificultad: Vestido oblicuo en placa y cabeza de alfiler
Opción: alinear la unidad.
Problema: protuberancia o rotación anormal de la cabeza del alfiler
Option:Replace the chain Lubricate and eliminate overload.
Problema: alargamiento por desgaste
Resolution:Substitute the chain when its length becomes 1.03L. Note: Wear elongation of the
La cadena reduce su resistencia a la tracción.
El vestido con un alargamiento del 3% reduce la resistencia a la tracción en un 18%.
The dress in lifestyle of chain could be improved by lubrication. Exchange the chain.
Challenge:Cracked plate (one)Crack: Through the hole of the hyperlink plate toward the finish from the website link plate inside the route perpendicular to stress course.
Option:Replace the chain that has a chain of greater maximum allowable stress, or reduced the load or dynamic (shock) load.
Problem:Cracked plate (two)Crack: In an oblique route against tension course.
Alternative:Substitute the chain, and safeguard from corrosive conditions.
Issue:Broken plate(by large stress)
Remedy:Exchange the chain, and remove the lead to of overload.
Problema: agujero de placa agrandado
Alternative:Exchange the chain, and do away with the cause of overload.
Problema: corrosión del pozo
Remedy:Exchange the chain, and safeguard from corrosive situations.
