BS 6413 is a series on lubricants, industrial oils, and related products (class L). A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth (called cogs), which mesh with another (compatible) toothed part to transmit (convert) torque and speed.
BS 6413-6 establishes the detailed classification of family C (gears) which belongs to class L (Lubricants, industrial oils, and related products). BS 6413-6 should be read in conjunction with ISO 6743-0. BS 6413-6 is concerned only with lubricants for industrial gears. Lubricants for motor vehicle gears may be included in a future edition.
BS 6413-6 on the classification of family C (gears) is useful for:
The basic principle behind the operation of gears is analogous to the basic principle of levers. Gear may also be known informally as a cog. To establish this classification, two essential series of parameters have been considered, one including the environment and the other considering the tooth operating conditions. These parameters are explained in BS 6413-6.
To establish this classification, two essential series of parameters have been considered those include the environment and the tooth operating conditions (load level and sliding velocity). These parameters are not the only ones to be considered when a lubricant has to be selected. Nevertheless, due to their importance and for clarification purposes, these parameters have been quantified. The values are given in BS 6413-6. Using BS 6413-6 you can establish the detailed classification of family C (gears) which belongs to class L.
