Abstract

The system is particularly for use with the leadscrews of machine tools, to adjust the clearance or pre-loading between a pair of nuts. A supporting bush accommodates a first nut, prevented from turning by a spring, and also a second nut, sliding axially and prevented from turning by a second spring. One end of this second nut has an external thread, whose handing and pitch is the same as that of the internal thread of the adjusting nut screwing onto it. The external thread of the adjusting nut has the same handing but a different pitch, and screws into a mating internal thread in the bush.
