What is BS 2519-2 - Glossary for gears - notation about?
Gears are used to transfer motion and torque between machine components in mechanical devices. BS 2519-2 is an International Standard that provides you with a glossary for gears.
BS 2519-2 is the second part of the BS 2519 multi-series, and specifies symbols for geometrical data for use in gear notation. It consists essentially of two parts:
- On the one hand, the principal symbol, is composed either of a single basic letter or of a basic letter and suffix or sign which are generally inseparable from the given term
- On the other hand, additional suffixes or signs may be added if necessary to the principal
- symbols, in order to imply a particular qualification of the given term
BS 2519-2 provides you with lists classified in alphabetical order according to the Roman and Greek alphabets, on the one hand, the basic letter symbols, and on the other hand the suffixes and signs which have been used in the establishment of BS 2519-2. You can then use a combination of these for the notation of any other term of geometrical data not explicitly mentioned in BS 2519-2.
Who is BS 2519-2 - Glossary for gears - notation for?
BS 2519-2 on a glossary for gears - notation is useful for:
- Manufacturers and suppliers of motors and components
- Product design engineers / innovation teams
- Mechanical engineers
- Quality control/testing personnel
- Fabricators
- Researchers
Users of motors and components such as:
- The aerospace industry
- The automotive industry
- The shipping industry
- The oil and gas industry
- Railways
- Electric power stations
- The construction industry
- The mining industry
Why should you use BS 2519-2 - Glossary for gears - notation?
Gears can serve as an efficient means to reverse the direction of motion, change rotational speed, or change which axis the rotary motion is occurring on.
BS 2519-2 aims to unify the symbols used in different countries for the international notation of gears with regard to the principal geometrical data defined in ISO/R 1122, Glossary of gears — Geometrical definitions.
These symbols have been chosen after a detailed comparative study, taking into account the necessity of retaining a certain number of letters for standardization of other notations at a later date, such as those dealing with gear accuracy.
Consequently, BS 2519-2 is instrumental in:
- Bringing national standards into line with this International Standard, so that in the future a real international language of notations will facilitate the exchange of documents between one country and another
- Using for geometrical data only combinations of letters or signs appearing in the alphabetical annex, in order to avoid any risk of confusion with notations to be determined later with regard to other gear data
BS 2519-2 guidelines enable the industry to use standardized vocabulary and notations worldwide, so that communication across the manufacturing industry is clear, and innovations as well as commerce are facilitated.
