Improving the efficiency of impact mining machines equipped with a cam impact mechanism
One of the options for ensuring the impact load in drilling machines is the use of an end cam mechanism, which allows you to rationalize the cam profile to increase the productivity of drilling operations. The article presents a solution to the problem of increasing the efficiency of drilling machines by taking into account not only the geometric parameters of the striking body, but also all the elements of the impact nodes. A computer model of the impact cam mechanism is presented, which makes it possible to evaluate its kinematic and dynamic characteristics.
