{"data":{"fields":"term_definition","term_definition":"<div class=\"definition\">Teeth that are curved and oblique. The line of contact between mating teeth is curved and oblique to the teeth. As with helical gears and skew bevels, the tooth contact starts at one end of the tooth and travels to the other end. Spiral bevel gears are smoother, quieter, and stronger than straight bevel gears and should be used for all high speed drives. These gears can be designed to have much better operation characteristics than skew bevel gears.<\/div><div class=\"align align-image align-left\" itemscope itemtype=\"http:\/\/schema.org\/ImageObject\"><img src=\"https:\/\/www.gleason.com\/images\/YYXval.4d97\/544w\/ED-151a.jpg\" alt=\"ED-151a\"><\/div><div class=\"align align-image align-left\" itemscope itemtype=\"http:\/\/schema.org\/ImageObject\"><img src=\"https:\/\/www.gleason.com\/images\/YYXval.4d97\/544w\/ED-151a.jpg\" alt=\"ED-151a\"><\/div><div class=\"align align-image align-left\" itemscope itemtype=\"http:\/\/schema.org\/ImageObject\"><img src=\"https:\/\/www.gleason.com\/images\/YYXval.4d97\/544w\/ED-151a.jpg\" alt=\"ED-151a\"><\/div>"}}
