ʻO kēlā ʻano ʻano helical internal gear e koi pinepine i ka hoʻololi ʻana i ka profile a ʻo ka pololei ʻo ISO6-7, ma mua o kēlā me kēia hoʻouna ʻana, e hāʻawi mākou ma lalo o kēia mau hōʻike i ka mea kūʻai aku e nānā i nā kikoʻī helical ring gear e hōʻoia i ka maopopo ʻana o nā mea āpau a maikaʻi i ka moku.

1) Kiʻi ʻōhū

2)Dhōʻike imension

3)He ʻai i ka hōʻike hōʻike ma mua o ka mālama wela

4)Hʻai hōʻike maʻi ma hope o ka mālama wela

5)Mhōʻike aterial

6)Ahōʻike pololei

7)Pictures a me nā wikiō hoʻāʻo āpau e like me runout, Cylindricity etc

8) Nā hōʻike hoʻāʻo ʻē aʻe no ka koi o nā mea kūʻai aku e like me ka hōʻike ʻike flaw
