Bevel gear
 N JIS B 1704

Annotation

This Standard specifies the classification system for the geometrical accuracy of bevel gears and hypoid gears. Also, this Standard defines the terms related to the gear accuracy and specifies the structure and tolerances of the gear accuracy grade. This Standard is applicable to a single gear and a pair of gears, and not applicable to the gear unit assembly.

The single pitch deviation tolerance and the total cumulative pitch deviation tolerance shall be described in Annex A, the single-flank composite deviation measuring method shall be described in Annex B, and the accuracy of small module bevel gears shall be described in Annex C.

NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 17485: 2006 Bevel gears—ISO system of accuracy (MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/lEC Guide 21-1.

Коническая передача

Этот Стандарт определяет систему классификации для геометрической точности конических передач и гипоидных передач. Кроме того, этот Стандарт определяет условия, связанные с точностью механизма, и определяет структуру и допуски класса точности механизма. Этот Стандарт применим к единственному механизму и паре механизмов, и не применим к сборке единицы механизма.
