Determination of the Rational Number of Cutters on the Outer Cutting Drums of Geokhod

cutters on the outer cutting drums of the geokhod for the formation
of grooves in medium strength rocks is considered in this article. It
is established that the coefficient of variation of the torque m
taken into account while determining the number of cutters. It is
established that the required feed velocities are realized with a
crown-type outer cutting drum at one or two cutters in the cutting
lines, and the coefficient of torque variation doe
any allowable number of cutters and equal lag angle. On the disk
type outer cutting drum required feed velocities are realized with
the number of cutters in the cutting lines from 1 to 4. The minimum
number of cutters providing a coefficient of variation of the torque
on the disk-type outer cutting drum above the set depends on the
angle of coverage and reduces with the increase of the angle of
coverage. The example of schematic designs of OCD AR and OCD
EP development is shown for a prototype model of geokhod (3.2 m
diameter) using the obtained expressions to determine the basic
geometric, kinematic, force, and structural parameters. The
possibility of decision making of the type of OCD for geokhod and
its creation is confirmed. The documentation design documents for
production crown-type OCD for a prototype of geokhod were
developed based on the conducted research.
