Abstract

The drive from the machine to the drill is via two circular faces lying close to one another and contg. a number of balls in pockets. The circular faces surround the spindle. The upper circular face is formed by a plate free to move axially and held in contact with the lower face by two disc springs and a coil spring in series. The spindle is threaded and onto this screws a cap which compresses the springs. The slipping torque can be adjusted by turning the cap, and so suit the slipping torque required by a wide range of drill sizes.
