L'aspect du produit varie selon la taille de l'accouplement et l'alésage fini. Consultez le tableau des modèles ci-dessous pour les dimensions et transmettez les spécifications des deux arbres pour l'usinage.
NM82 Flexible Coupling
NM82 provides 28 N.m nominal torque, up to 32 mm bore capacity and a rated speed limit of 3000 rpm. It is suited to compact pumps, fans and light machinery when torque, shaft fit, alignment and installation space are all within the model limits.
NM82 technical data
NM82 sits between the compact NM67 and the larger-bore NM97. Its 32 mm maximum bore makes it relevant to many small and medium rotating-equipment interfaces where shaft fit becomes the first sizing filter.
| Modèle | Couple nominal | Limitation de vitesse | D | D1 | d max | L | S | Radial | Angulaire |
|---|---|---|---|---|---|---|---|---|---|
| NM82 | 28 Nm | 3000 tr/min | 82 mm | 53 mm | 32 mm | 40 mm | 3.0 +/- 1.0 mm | 0.05 mm | 3.0 deg |
Les valeurs D, D1, d max, L, S et radiales sont exprimées en millimètres. Le déplacement angulaire est indiqué en degrés. Sur les petits écrans, faites glisser le tableau horizontalement pour afficher toutes les colonnes.
Contrôles d'ajustement et d'usinage
Check the 82 mm outside diameter, 53 mm D1 and 40 mm length against the actual machine space. A coupling can satisfy torque and still be awkward to install if the guard opening or shaft projection is limited.
Où cette taille convient
The nominal rating is 28 N.m with a 3000 rpm speed limit. NM82 can be evaluated for pump sets, blowers and machinery with moderate continuous duty, but loaded starts and repeated cycling should be stated rather than hidden inside a generic motor-power figure.
Alignement et assemblage
Use the 3.0 +/- 1.0 mm S value when positioning the hubs. The stated radial limit is 0.05 mm and the angular limit is 3.0 degrees; verify them after the machines are fully assembled and tightened.
Prepare the NM82 RFQ
An efficient NM82 RFQ includes both bore/keyway requirements, running speed, design torque or motor power, the driven machine and quantity. For a retrofit, add the old coupling envelope so installation space can be compared before machining.
Conditions matérielles et de service
The standard NBR element provides the flexible connection for this range. If service includes oil, heat, chemicals or unusual cycling, describe that environment and request the required polymer or hardness explicitly.
Comparez les tailles NM les plus proches
If a shaft exceeds 32 mm or the torque margin is too small, move the comparison to NM97. Where packaging is very tight, also check whether NM67 can satisfy both bore and duty.
