Universal Joints - Precision Gears

The Department of Army, Rock Island Arsenal Joint Manufacturing Technology Center, is conducting market research to identify qualified sources capable of manufacturing universal joints. The scope of work includes the manufacturing of two precision gears with specific capabilities, such as breaking load, materials, certificate of conformance, spline feature, precision requirements, manufacturing processes, finish requirements, and quality assurance provisions. The information received will be used to assess the availability of qualified vendors and to develop a future acquisition strategy. This project supports the manufacturing of self-propelled artillery. • Breaking load: Static torque rating of 9000 in-lbs. compression or tension load 10,000 lbs. min. • Materials: Steel alloy per ASTM A340 • Certificate of Conformance: Stating steel utilized conforms to specification ASTM A304 and product meets all requirements of drawing • Spline feature: internal involute spline, per drawings 10953657 and 10953661 data tables • Precision Requirements: Tight tolerances (±0.005” or better) may be required on certain features • Manufacturing Processes: CNC spline, grinding, shaping, and milling • Finish Requirements: Finish 5.3.1.3 is a heavy manganese class 3 phosphate coating without supplemental oil and 5.3.2.3 is a heavy zinc class 3 phosphate coating without see note 5 • Quality Assurance provisions: Drawing 13101232 applies to both drawings
