  • Patent number: 7802508
    Abstract: A high speed braider, includes a main shaft, driven by a prime motor. The main shaft drives rotating shafts of inner and outboard spindle driving disks through a cylindrical gear transmission mechanism. The cylindrical gear transmission mechanism includes a main shaft gear and two translating gears. The main shaft gear engages with one of the cylindrical gears on the shaft of the inner or outboard spindle driving disks, and the two translating gears rotate together, of which, one engages with the cylindrical gear on the main shaft, another engages with the other of the cylindrical gears on the shafts of inner or outboard spindle disks. The transmission ratio between the rotating shaft of the inner spindle driving disk and the main shaft is equal to the transmission ratio between the rotating shaft of the outboard spindle driving disk and the main shaft.
