- Description
- This is a modification to the synopsis entitled COMMERCIAL FABRICATION OF TEST GEARS. SOLICITATION NO.NNC06153387Q which was posted on 4/20/2006. You are notified that the following specifications are added. The gear geometry shall be verified by measurement on an appropriate gear checking machine. Conformance of gear tooth profile, lead, and tooth spacing requirements meeting AGMA class 13 shall be verified, and the measurements provided to NASA. Three gears (minimum) shall be checked, one each from the first 1/3rd, middle 1/3rd and last 1/3rd of the parts process through the final grinding operation. 7. The gears shall have the gear working surfaces carburized and hardened per AMS 2759/7 with a minimum surface hardness of 58 Rockwell C. Applied depth: 0.030 to 0.040 inch, finished depth: 0.022 to 0.038. The gears shall be verified as free of grinding burns. 8. Parts shall be checked for hardness after the quenching operation and before the subzero cool operation. Parts shall have a minimum hardness of Rc 58, parts not meeting this requirement shall be rejected as unacceptable. 9. The manufacturer shall provide a certificate stating compliance with part geometry, material specification, results of heat treatment quality control, results of shot peening quality control, and results of grinding burn quality control conformance. 10. The gears shall be marked with serial numbers of the form “9310-06-XXX”. 11. Table 1 provides a heat treatment cycle that has been used successfully for gears of a similar overall size but different pitch (the table has been used for 8 pitch gears; purchase requirement is for 12 pitch gears). TABLE 1 —Heat treatment guideline for AISI 9310 Gears. (Note: The manufacturer shall deviate from this guideline as appropriate such that all operations are completed and such that final requirements for case depth, case properties, and core properties are met). Step 1.) Process = Preheat in air Step 2.) Process = Carburize * Temperature: K = 1,172 ºF = 1,650 * (time, hr 8 ) Step 3.) Process = Air cool to room temperature Step 4.) Process = Copper plate all over Step 5.) Process = Reheat * Temperature: K = 922, ºF = 1,200 * (time, hr 2.5) Step 6.) Process = Air cool to room temperature Step 7.) Process = Austentize * Temperature: K = 1,117, ºF = 1,550 * (time, hr 2.5) Step 8.) Process = Oil quench Step 9.) Process = Subzero cool * Temperature: K = 180, ºF = -120 * (time, hr 3.5) Step 10.) Process = Double temper * Temperature: K = 450, ºF = 350 * (time, hr 2 each) Step 11.) Process = Finish grind Step 12.) Process = Stress relieve * Temperature: K = 450, ºF = 350 * (time, hr 2) The due date for responses 05/05/2006 is not extended. Documents related to this procurement will be available over the Internet. These documents will reside on a World Wide Web (WWW) server, which may be accessed using a WWW browser application.
