Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Fig. 2 is the A-A structural representation of Fig. 1.
In figure, axle 1, speed regulator 2, spring I3, pulley 4, belt 5, spring II6.
Detailed description of the invention
Adopting stepless time adjustment is a kind of angular velocity according to own rotation, and the way regulating output maximum radius realizes, and namely speed is more fast, and transmission radius is more big.
Describe the present invention below in conjunction with accompanying drawing.
The present invention as it is shown in figure 1, include axle 1, speed regulator 2, spring I3, pulley 4, belt 5, spring II6,
Described axle 1 two ends are with spacing end face, and axle 1 is by spline through speed regulator 2, and speed regulator 2 is horizontal truncated cone-shaped；Speed regulator 2 two ends are with spacing end face, being provided with spring I between horizontal truncated cone-shaped speed regulator bottom surface and the spacing end face of axle, the conical side surface of speed regulator is provided with pulley drive group and belt transmission group, pulley 4 and belt 5 and all touches with the conical side surface of speed regulator,, and coordinate transmission；Pulley is connected to spring II, it may be achieved flexible.
Operation principle of the present invention:
After this Product Assembly, pulley 4, under the effect of spring II6, is pressed on the conical surface of speed regulator 2, and it is made a concerted effort to horizontal truncated cone-shaped speed regulator 2 bottom surface, and force value is slightly larger than spring I3.
When axle 1 is static, debugger 2, under the effect of spring I3 and pulley 4, is made a concerted effort to horizontal truncated cone-shaped speed regulator 2 bottom surface, and at this moment speed regulator 2 and axle 1 tightly compress spring I3, and at this moment belt 5 is at the cross section end of horizontal truncated cone-shaped speed regulator 2, and the radius of gyration is minimum.After axle 1 rotates, device can produce centrifugal force, when after the centripetal force that centrifugal force produces more than spring 6, pulley 4 moves to horizontal truncated cone-shaped speed regulator 2 bottom end, at this moment, make a concerted effort less than spring I3, owing to speed regulator exists certain tapering, speed regulator moves to the other end of axle, the spring force of balancing spring I3, belt 5 will move relative to round platform bottom surface, at this moment the radius of gyration becomes big, belt 5 output lead speed also becomes big, when speed reduces, centrifugal force diminishes, pulley 4 moves to round platform cross section end, the resultant direction of pulley 4 and spring 3 is to round platform bottom surface, speed regulator is to axle spring side shifting, belt 5 will move relative to round platform cross section, at this moment the radius of gyration diminishes, thus realizing stepless time adjustment.
The present invention experiment proves that, for ensureing that speed regulator can move smoothly, action is sensitive, the conical surface gradient of usual speed regulator is at 10-20 degree, with about 15 degree for the best, and the active force slightly larger than spring I3 of making a concerted effort of spring II6, less than 1.3 times, the quantity of spring II6 and pulley 4 is 6 groups or more.
The unspecified part of the present invention is known to the skilled person technology.
