1 Scope

GB/T 10107.3-2012 is the Chinese national standard on cycloidal drives - part 3: symbols of geometrical data, in the field of mechanical systems and components. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 3 September 2012 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 March 2013.

The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This section GB/T 10107 provisions of the cycloid, planetary drive wheel and geometrical data symbols. This section applies to Cycloid Drive.
