Analysis of technical capabilities of cylindrical straight-tooth

The article deals with the advantages and disadvantages of articulated gear – straight-toothed cylindrical transmission, in which the teeth have convexconcave profiles and interact with each other on the surface. The surface contact of teeth of this transmission provides reduction of contact stresses in gearing in 7-50 times in comparison with involute. It is established that the articulated gear provides a fairly smooth rotation of the driven wheel: the coefficient of unevenness of the stroke is not higher than 0.012. The main disadvantage of this transmission is the radial shocks caused by the oscillation of the center distance. Therefore, gearshifts are recommended for use only at minimum speeds, for example in manual drives.
