About influence of accuracy of manufacture of links on E.F. of screw coaxial mechanisms

Abstract

Three-link screw mechanisms converting translational motion into rotational motion are widespread due to their compact design. They are used in pneumatic drilling hammers and perforators, the annual production of which for mining and construction industry only in our country counts' hundreds of thousands of units. Development of the national economy puts forward the tasks of increasing the productivity of this equipment and increasing the efficiency of mechanisms perforators.
