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.
NM194 Flexible Coupling
NM194 provides 840 N.m nominal torque, up to 85 mm bore capacity and a rated speed limit of 1500 rpm. It is suited to higher-torque pumps, compressors and process equipment when torque, shaft fit, alignment and installation space are all within the model limits.
NM194 technical data
NM194 moves into the large end of the NM range with 840 N.m nominal torque and an 85 mm maximum bore. Unlike NM168, its rated speed limit is 1500 rpm, so speed becomes a decisive selection check rather than a secondary line in the table.
| Modèle | Couple nominal | Limitation de vitesse | D | D1 | d max | L | S | Radial | Angulaire |
|---|---|---|---|---|---|---|---|---|---|
| NM194 | 840 Nm | 1500 tr/min | 194 mm | 140 mm | 85 mm | 100 mm | 3.5 +/- 1.5 mm | 0.10 mm | 2.0 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
This coupling is 194 mm in outside diameter and 100 mm long. Allow enough room for the rotating envelope, guard and maintenance access, and verify that shaft shoulders do not interfere with the required hub position.
Où cette taille convient
NM194 can be evaluated for higher-torque pumps, compressor auxiliaries and process equipment that operate within the 1500 rpm limit. Provide start method, load changes and shock details because the large nominal rating does not replace a duty review.
Alignement et assemblage
The specified S value is 3.5 +/- 1.5 mm. Radial misalignment is limited to 0.10 mm and angular misalignment to 2.0 degrees. A heavy machine train should be aligned after piping, guards and other connected loads are in their final condition.
Prepare the NM194 RFQ
For NM194, send the exact running speed before anything else if the machine is near 1500 rpm. Then add both bores and keyways, design torque, driven equipment, quantity and any drawing-controlled machining requirement.
Conditions matérielles et de service
The standard ring material is NBR. If the installation has heat, oil, chemicals or a specified elastomer hardness, include those conditions so the quoted element matches the service requirement.
Comparez les tailles NM les plus proches
If 840 N.m or 85 mm bore capacity is not enough, NM214 is the next size and keeps the same 1500 rpm speed class. If the machine runs above 1500 rpm, return to the selection basis rather than simply upsizing.
