Description
The continuous increase in requirements for the surface quality of elements in machine-building products, particularly gear transmissions, necessitates the improvement of machining and control methods. A major influence on the smoothness and noiseless operation of power transmissions is the correct selection of the method for machining the base holes of gears.
The methods currently known for final hole machining—such as countersinking, reaming, grinding, etc.—do not guarantee sufficient wear resistance. Consequently, during assembly with the shaft journals transmitting torque, they do not ensure the prescribed kinematic accuracy in gear transmissions.
This necessitates conducting research on the combined machining of holes in gear blanks and de-termining machining regimes that affect surface roughness and microhardness.
Keywords: kinematic accuracy, machining quality, surface machining.
