Abstract
Provided is a gear mechanism in which power transmission efficiency is good and strength of gear does not reduce. The gear mechanism 10 is provided with a gear body 12 in which a plurality of gears is stacked in a rotation axis direction, each gear being equipped with a disk portion 16 and a plurality of teeth 18 arrange at equal intervals on the outer periphery of the disk portion 16. The plurality of stacked gears 14 is shifted in the rotation direction such that the contact ratio is 1 or more. When the reference module of the gear 14 is m′, the diameter of the pitch circle is d, the number of teeth of the gear 14 is zA, and the number of gears 14 is a, m′=d/(zA×a) is satisfied.
Claims5
A gear mechanism comprising:
- a gear body in which a plurality of gears is stacked in a rotation axis direction and fixed to each other, each of the plurality of gears being provided with a disk portion and a plurality of teeth arranged at equal intervals on an outer periphery of the disk portion,
- wherein the plurality of stacked gears is shifted in a rotation direction such that a contact ratio is 1 or more, and
- wherein a tooth depth of the plurality of teeth equipped by each gear is lower than a tooth depth of a standard tooth form of a gear in which a diameter of a pitch circle and the number of teeth are the same as those of each of the plurality of tooth.
