ELECTRIC PULSE TUBE EXPANDER

摘要

ELECTRIC PULSE TUBE EXPANDER The electric pulse tube expander according to the invention comprises a bed with a vertical guide and horizontal guides mounted thereon. An electrode is movable mounted on the vertical guide. Mounted on the horizontal guides are drives for moving the electrode in the vertical and horizon tal planes. The drives contain electromotors, reducers and mechanisms for setting the pitch of the electrode motion. Each of said mechanisms comprises a reducer whose drive gear is kinematically coupled to a lead screw, whereas its driven gear has a strip mounted on its shaft, which periodically interacts with a limit switch of a tube expander control system.
