MIL-C-18087A

Abstract

This specification covers clutches for Naval shipboard propulsion units and auxiliary machinery. This specification does not include all types of clutches but is intended to cover those types most widely used in shipboard propulsion and auxiliary systems. <br>Clutches shall be of the following types as specified (see <a>6.2</a>): </span><pre> Type I - Nonpositive drive hydraulic (fluid drive). Type II - Nonpositive drive friction (tire and tube). Type III - Nonpositive drive friction (disc, drum, or cone) (see <a>6.8.2</a>). Type IV - Nonpositive drive overrunning (see <a>6.8.3</a>). Type V - Positive drive (see <a>6.8.1</a>) forced synchronizing. Type VI - Positive drive overrunning. Class A - Automatically actuated. Class B - Remotely controlled.</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 55Z3, Department of the Navy, 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> <br><b><u>Intended Use:</u></b> This specification is intended to be applied to clutches for service on propulsion units for Navy ships. The intended arrangements and details are those of conventional design (similar units having been built previously and installed on board Navy ships or comparable commercial ships). When a departure from conventional design is contemplated, consideration should be given to applying this specification as a general guide for construction of a prototype. The prototype shall be tested and evaluated to assure that it is suitable for Navy use prior to the manufacture of production models. <br>
