  2. List of DIN standards - Wikipedia

    en.wikipedia.org/wiki/List_of_DIN_standards

    This is an incomplete list of DIN standards.. The "STATUS" column gives the latest known status of the standard.. If a standard has been withdrawn and no replacement specification is listed, either the specification was withdrawn without replacement or a replacement specification could not be identified.

    Today industry and ISO also do a lot of this standardization specification, freeing the U.S. DOD and military to do less of it (as explained at United States Military Standard > Origins and evolution), although many MIL standards are still current. (See also MS-and NAS.) ANN: anneal, annealed: ANSI: American National Standards Institute

    Shaft angle. A shaft angle is the angle between the axes of two non-parallel gear shafts. In a pair of crossed helical gears, the shaft angle lies between the oppositely rotating portions of two shafts. This applies also in the case of worm gearing. In bevel gears, the shaft angle is the sum of the two

  5. Geometric dimensioning and tolerancing - Wikipedia

    en.wikipedia.org/wiki/Geometric_dimensioning_and...

    Example of true position geometric control defined by basic dimensions and datum features. Geometric dimensioning and tolerancing (GD&T) is a system for defining and communicating engineering tolerances via a symbolic language on engineering drawings and computer-generated 3D models that describes a physical object's nominal geometry and the permissible variation thereof.

  6. Engineering tolerance - Wikipedia

    en.wikipedia.org/wiki/Engineering_tolerance

    The standard (size) tolerances are divided into two categories: hole and shaft. They are labelled with a letter (capitals for holes and lowercase for shafts) and a number. For example: H7 (hole, tapped hole, or nut) and h7 (shaft or bolt). H7/h6 is a very common standard tolerance which gives a tight fit.

  7. Shaft (mechanical engineering) - Wikipedia

    en.wikipedia.org/wiki/Shaft_(mechanical_engineering)

    In mechanical engineering, a shaft is a rotating machine element, usually circular in cross section, which is used to transmit power from one part to another, or from a machine which produces power to a machine which absorbs power.

  8. Power take-off - Wikipedia

    en.wikipedia.org/wiki/Power_take-off

    A split shaft PTO is mounted to the truck's drive shaft to provide power to the PTO. Such a unit is an additional gearbox that separates the vehicle's drive shaft into two parts: The gearbox-facing shaft which will transmit the power of the engine to the split shaft PTO; The axle-facing shaft which transmit the propelling power to the axle.

  9. Geometrical Product Specification and Verification - Wikipedia

    en.wikipedia.org/wiki/Geometrical_Product...

    Geometrical Product Specification and Verification (GPS&V) [1] is a set of ISO standards developed by ISO Technical Committee 213. [2] The aim of those standards is to develop a common language to specify macro geometry (size, form, orientation, location) and micro-geometry (surface texture) of products or parts of products so that the language can be used consistently worldwide.
