A full-roller transmission structure, comprising:
- a housing including a rear cover, an annular shell, and a front ring, wherein two opposing sides of said annular shell is coupled to said rear cover and said front ring respectively, said rear cover, said annular shell and said front ring being detachably coupled together by using a plurality of coupling bolts, or said rear cover, said annular shell and said front ring being formed into an integral body, and wherein a plurality of inner rollers are disposed on an inner surface of said annular shell at an equal angular interval;
- a first disk mounted in said annular shell, adjacent to said rear cover, wherein said first disk is provided with a plurality of first outer rollers on a circumference thereof, said first outer rollers being arranged at an equal angular interval and capable of acting on said inner rollers, and wherein said first disk defines a first shaft hole at a center thereof and at least two first through holes being arranged at angular intervals;
- a second disk mounted in said annular shell, adjacent to one side of said first disk away from said rear cover, wherein said second disk is provided with a plurality of second outer rollers on a circumference thereof, said second outer rollers being arranged at an equal angular interval and capable of acting on said inner rollers, each said first outer roller being angularly offset from a corresponding second outer roller so that each of said first outer rollers is placed between two of said second outer rollers, and wherein said second disk defines a second shaft hole at a center thereof being coaxially with said first shaft hole of said first disk, and defines at least two second through holes being arranged at angular intervals and corresponding to said first through holes of said first disk respectively;
- a rear disk mounted in said housing between said first disk and said rear cover;
- a front disk mounted in said housing, adjacent to one side of said second disk away from said first disk, wherein said front disk defines a third shaft hole at a center thereof being coaxial with said first shaft hole of said first disk and said second shaft hole of said second disk, and wherein at least two joining bolts and at least two joining pins are arranged at an equal angular interval to be fitted with said rear disk, and inserted through said first through holes of said first disk and said second through holes of said second disk to be fitted with said front disk, each of said joining bolts being placed between two of said joining pins, each said joining bolt having a diameter less than each said first through hole of said first disk and each said second through hole of said second disk, each said joining pin having a diameter less than each said first through hole of said first disk and each said second through hole of said second disk;
- and
- an input shaft including a first eccentric journal and a second eccentric journal adjacent to said first eccentric journal, the eccentricity of said first eccentric journal being offset from the eccentricity of said second eccentric journal at an angle of about 180 degrees, said input shaft being insert through said first shaft hole of said first disk and said second shaft hole of said second disk, said first eccentric journal being located corresponding to said first shaft hole of said first disk, said second eccentric journal being located corresponding to said second shaft hole of said second disk.
