Transmission mechanism for spring winding machine

A transmission mechanism used in a spring winding machine comprising:

• a rotary table, said rotary table having a first side, a second side, a center wire passage hole through the center of said first side and said second side, a main shaft eccentrically extended through said first side and said second side, said main shaft having a first end protruding over said first side and a second end protruding over said second side, and a driven gear mounted on the first end of said main shaft;
• a wire feeding box fixedly mounted on the second side of said rotary table, said wire feeding box comprising an intermediate gear, a transfer cylinder set formed of a wire-transfer cylinder and an impression cylinder adapted for transferring a spring wire through said center wire passage hole of said rotary table, a spur gear coaxially connected to said wire-transfer cylinder and meshed with said intermediate gear, a first bevel gear fixedly mounted on the second end of said main shaft, and a second bevel gear coaxially connected to said intermediate gear and meshed with said first bevel gear;
• a wire feeding motor installed in the first side of said rotary table, said wire feeding motor having an output shaft and a pinion fixedly mounted on said output shaft and meshed with said driven gear at said main shaft;
• and
• a reversible wire winding motor coupled to said rotary table through a transmission belt and adapted for rotating said rotary table clockwise/counter-clockwise through 180°.
