Abstract

A borehole drive for a rock crushing instrument comprises a driving unit (1) connected kinematically to a spindle unit (2). The spindle unit (2) has a casing (16) with a shaft (6) passing through it and connected to the rock crushing instrument. The shaft (6) is mounted inside the casing (16) by means of radial supports and coaxial rings (14) and races (13) with rolling bodies (8) kept between the rings (14), the races (13) and the shaft (6). The shaft is provided with toroidal grooves in direct contact with the rolling bodies (8).
