the technological scheme that the present invention solves its technical problem is:a kind of direct-drive stepless speed changes devices, mainly comprise position shelf, input initiatively shaft of bevel gear, export driven shaft of bevel gear, input gear pedestal, input driven bevel gear, initiatively diameter-changing wheel, output gear pedestal, driven diameter-changing wheel and output initiatively bevel gear, described active diameter-changing wheel and described driven diameter-changing wheel are circular arc scanning body structure, become large from little bottom surface to large plane perpendicular successively in the radius of axis, top layer is abrasive rubber, and is provided with the cylindrical shaft of coaxial line outside two bottom surfaces.
The same plane of described position shelf is provided with two perforation, and described input initiatively shaft of bevel gear and the driven shaft of bevel gear of described output is separately fixed in two perforation by bearing.
Described input gear pedestal and described output gear pedestal are the dihedral steel body of casting that angle is greater than that 0 ° is less than 180 °, two gussets are respectively provided with a perforation, and the plane that any center line at the axis that two gussets are linked to be with the summit at angle and angle is determined is for symmetry plane full symmetric.
The cylindrical shaft of described active diameter-changing wheel and side, described driven diameter-changing wheel little bottom surface is fixed on described input gear pedestal and described output gear pedestal respectively by bearing.
The driven bevel gear of described input and described output initiatively bevel gear are fixed on the top of described active diameter-changing wheel and side, described driven diameter-changing wheel little bottom surface cylindrical shaft respectively by lid silk and key, and are meshed with the described gear inputting initiatively shaft of bevel gear and the driven shaft of bevel gear of described output respectively.
Combine closely all the time in described active diameter-changing wheel and described driven diameter-changing wheel surface, by the relative static friction transmission of the abrasive rubber on top layer, and by respectively with described input initiatively shaft of bevel gear and the driven shaft of bevel gear of described output for axle rotates, described input gear pedestal and described output gear pedestal change the mode in conjunction with radius of described active diameter-changing wheel and described driven diameter-changing wheel, continuously change output speed and the moment of torsion of the driven shaft of bevel gear of described output, there is no differential change, achieve stepless change.
the invention has the beneficial effects as followscompared with prior art, variable speed drive is simplified greatly, not only greatly reduce manufacture requirements and cost of production, and achieving good level and smooth variable transmission, whole device transmission performance is good, efficiency is high, and maintains simple, with low cost, can Large-torsion transmisson be met, widely applicable and be easy to promote.
