Gear and s

7、pline data depicted on drawings prepared by contractors for the Government has varied considerably. Problems of interpretation have been encountered because of the varied methods of specifying gear and spline data on drawings. The problems have ranged from omission to over-specification of data that

8、 impaired the quality and decreased the reliability of secondary procurement parts. To alleviate gear and spline specification problems, a technical committee, to be known as the USATACOM Gear and Spline Technical Committee, was formed early in 1958. The committee was made up of personnel having kno

9、wn gear and spline talents and product design, manufacturing, tooling, and product assurance. The objective of the committee was to develop a series of formats to provide necessary guidance for uniform specification of gear and spline data on tank-automotive drawings. The initial set of formats enti

10、tled, STANDARD DATA PRESENTATION FOR GEARS, SPLINES AND SERRATIONS,“ was published in September 1958 for use by tank-automotive design activities. standard data presentation formats had proven their worth as a guide and reference in the establishment of uniform design practice, the formats were not

11、contractually binding. Consequently, the permissible latitude in the method of specifying gear and spline engineering data by defense contractors allowed certain variations and inadequacies to creep into drawings. Even though the In 1965, the committee recognized the need for expanding the scope of

12、gear and spline requirements for preparation of engineering drawings. It was agreed that a harmonious interface of applicable military and industrial standards was needed. A decision was made to prepare a handbook consolidating all the gear and spline drawing preparation requirements under one cover

13、. As a handbook it provides a convenient means of implementing uniform engineering drawing preparation practices. It further provides regulatory control over various types of gears and splines, assuring adequate specification of data essential to design, competitive procurement, manufacture, and acc

14、eptance of gear and spline components for the Department of Defense (DoD). In addition, the handbook will serve as a textbook for specialized programs of instruction, for centralized or local training, and as a preparedness measure for accelerated training of Government and contractor personnel duri
