Medidor de prueba de alargamiento de desgaste de cadena

Este medidor verifica el alargamiento por desgaste de las cadenas.
Verify the chain elongation at a portion that’s most
frequently engaged with all the sprockets (portion almost certainly for being worn).
Once the center of your pin from the chain for being measured
Este medidor verifica el alargamiento por desgaste de las cadenas.
Check out the chain elongation at a portion and that is most
comúnmente engaged together with the sprockets (portion probably to get worn).
When the center on the pin of your chain to get measured reaches the arrow stage, it means that the chain continues to be critically elongated. In this case, change the chain.
Make use of the gage to check the wear elongation of your chain.
Términos básicos para piñones
Cantidad nominal de piñones
The nominal amount of a sprocket will be the exact same because the nominal number of the corresponding chain. One example is, Chains such as 50, 50HK, and 50LD is usually engaged by using a sprocket 50. It’s followed by symbols and characters indicating the number of chain strands, the amount of sprocket teeth, hub kind, tooth head hardening, etc.
Diámetro del agujero listo y acabado del agujero del eje
A typical sprocket for a single strand or double strand chain features a shaft hole prepared at a diameter stated during the table of dimensions. Once you finish the shaft hole, machine it in reference to your outer diameter or root diameter.
Endurecimiento de las cabezas de los dientes
The teeth of the sprocket has to be tough and put on resistant as they are impacted when engaged with the rollers on the chain and worn by sliding with the rollers. When serious wear and massive shocks are anticipated, sprocket.
Sorts, development and components
manufactured from carbon steel or cast steel really should be utilised and high-frequency hardening should really be conducted.
The common sprockets forty to 120 that has a hub on just one side for single and double strand chains are induction-hardened even when the number of teeth is smaller. No matter if the solution is induction hardened or not is proven during the tables of dimensions of respective sprockets for your reference. On top of that, inside the following situations, induction-harden the teeth with the sprocket.?The modest sprocket has twenty or less teeth and is employed at 1/6 or more from the optimum pace stated while in the table of highest kilowatt ratings.
The modest sprocket is used at a alter gear ratio of 4:one or far more.
The modest sprocket is made use of to get a lower velocity substantial load transmission as in circumstances of variety according to the “Low-speed selection”.
Sprockets are used in conditions wherever the teeth are heavily worn.
Sprockets are used beneath conditions the place there are frequent commences and stops or sudden typical or reverse rotations.
Precauciones básicas
For picking the quantity of teeth and pace ration of the sprocket, see “How to pick good chain” . For cautions for installing a sprocket on the shaft and replacement timing, see “Installation adjustment maintenance” .
