ABSTRACT:
The arc gear with a rotary transmission of 1:1 has an inner toothed toothwheel, an outer toothed toothwheel, each connected to a shaft, one of the shafts being for drive and one for output. The shafts are arranged eccentrically with an eccentricity and parallel to one another. There are provided concave power transmission surfaces, with a first radius of curvature measured from the centers of first circles, on teeth of one of the toothwheels, and convex power transmisison surfaces, with a second radius of curvature measured from the centers of second circles, on teeth of the other of the toothwheels, both of the toothwheels having the same number of power transmission surfaces. Two of the concave power transmission surfaces lie on the same one of the first circles. Two of the convex power transmission surfaces lie on the same one of the second circles. The first radius and the first circles are bigger than the second radius and the second circles. Between the two of the convex power transmission surfaces that lie on the same first circle are at least two other of the convex power transmission surfaces, and between the two of said concave power transmission surfaces that lie on the same second circle are at least two other of the concave power transmission surfaces. And the difference in length between the first radius and the second radius is the eccentricity.
