{"data":{"fields":"term_definition","term_definition":"<div class=\"definition\">The value of the diametral pitch as calculated in a normal plane of a helical gear or worm. The ratio of the number of teeth to the inches in the pitch diameter. There is a fixed relation between diametral pitch (DP) and circular pitch (CP), namely CP=DP. On bevel and hypoid gears, it is understood to be the transverse diametral pitch. See drawing: A gear with 12 Teeth and a 1\u201d pitch diameter is 12 Pitch.<\/div><div class=\"align align-image align-left\" itemscope itemtype=\"http:\/\/schema.org\/ImageObject\"><img src=\"https:\/\/www.gleason.com\/images\/t5L7Fr.2940\/544w\/ED-108.jpg\" alt=\"ED-108\"><\/div>"}}
