MIL-C-23233A

Abstract

This specification covers flexible couplings for propulsion units, auxiliary equipment, and line shafts. <br>Couplings are of the following types and classes as specified (see <a>6.2</a>): </span><pre> Type I Dental coupling lubricated by oil circulation. Class 1 275 minimum Brinell tooth hardness. Class 2 350 minimum Brinell tooth hardness. Class 3 Nitrided, 49 minimum Rockwell C tooth hardness. Class 4 Carburized or induction hardened, 56 minimum Rockwell C tooth hardness. Class 5 Nitrided, 59 minimum Rockwell C tooth hardness. Type II Dental coupling, self-contained (grease) lubricant. Class 1 Commercial, 160 minimum Brinell tooth hardness. Class 2 275 minimum Brinell tooth hardness.</pre> <br> <strong>Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: Commander, Naval Sea Systems Command, SEA 05Q42, 2531 National Center, Bldg. 3, Washington, DC 20362-5101 by using the self-addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.</strong> <pre> Type III Laminated-disc coupling. Type IV Nonmagnetic, noise-attenuation coupling. Type V Line-shaft noise-attenuation coupling assembly. Type VI Diaphragm coupling. Type VII Elastomer flexible coupling. Type VIII Connect or disconnect dental coupling.</pre> <br> <br><b><u>Intended Use:</u></b> Equipment described by this specification will be a permanent installation on Naval ships and is used to transmit power from prime mover, electric motor or reduction gear (as applicable) for propulsion or from prime mover to driven equipment for auxiliaries. <br>
