This invention provides a high-precision gear transmission backlash elimination mechanism, comprising a fixed gear and a movable gear. The fixed gear is integrally machined onto the gear shaft, and a raised arc-shaped pad is provided on its end face near the movable gear. The movable gear is coaxial with the fixed gear and has the same tooth profile. A coaxial arc-shaped groove is provided on the movable gear at a corresponding position to the arc-shaped pad. A wedge block is inserted between the arc-shaped groove and the arc-shaped pad, causing an angular offset between the movable gear and the fixed gear. An adjusting screw mounting hole is provided on the end face of the movable gear near the arc-shaped groove adjacent to the wedge block. Screwing in the adjusting screw presses the wedge block in, eliminating backlash while preventing the wedge block from loosening. As the gear wears down over time, increasing backlash, it can be eliminated by screwing in the adjusting screw. The gear transmission system using this backlash elimination mechanism has no significant change in size and features high speed resistance, heavy impact load resistance, and high precision.

This invention provides a helical pressure mechanism and a helical pressure device. The helical pressure mechanism includes: a primary screw, a push rod, and a power mechanism. The primary screw has a primary screw hole. The push rod is threaded into the primary screw hole. The power mechanism includes a flywheel and a clutch. The clutch can selectively connect to either the primary screw or the push rod. When the clutch is connected to the primary screw, the rotational force of the flywheel is transmitted to the primary screw. The threaded engagement force between the primary screw and the push rod causes the push rod to move in the direction of pressure application. When the clutch is connected to the push rod, the rotational force of the flywheel is transmitted to the push rod. The threaded engagement force between the push rod and the primary screw causes the push rod to move in the opposite direction of pressure application. During the reciprocating movement of the push rod to achieve the stamping operation, the flywheel maintains rotation in the same direction, thus allowing the small-power motor to continuously store energy and achieve high-power output.
