Abstract

A lead screw is formed by cutting spiral channel 10 about the circumference of tube 11. A length of commercially available spring wire is wound in a helix 12 which is inserted over and wound on tube 11. The convolutions of helix 12 are received in channel 10.

Lead Screw

A lead screw is formed by cutting spiral channel 10 about the circumference of tube 11. A length of commercially available spring wire is wound in a helix 12 which is inserted over and wound on tube 11. The convolutions of helix 12 are received in channel 10.

The assembly is then heated for a sufficient time and at a sufficient temperature to stress relieve the spring wire. After the stress relieving operation, the convolutions of helix 12 tightly grip tube 11.
