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:
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.
BS 2519-2 on a glossary for gears - notation is useful for:
Users of motors and components such as:
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:
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.
