Abstract (en)

[origin: JPH05256268A] PURPOSE: To obtain a gear-type machine capable of reducing noise generation and enhancing mechanical efficiency. CONSTITUTION: An internally toothed ring gear 3 meshes with a pinion 6 having only one tooth less than the gear. For the purpose of reducing noise, the teeth of the pinion 6 are only half as wide as the internally toothed ring gear 3. The cycloids of the internally toothed ring gear 3 and/or the pinion 6 are flattened in order to ensure adequate free passage of the teeth heads in a region opposite the point of deepest teeth engagement of the two gears in spite of minimum clearance.
