When body builder is when running certain lift instantaneously (running platform assembly 200), now running platform assembly 200 is in upper position under the effect of return spring assembly 307; When certain only rides upper running platform assembly 200, pressure can be produced to it, this pressure can make running platform assembly 200 (driving roller for running apparatus 100 assembly) move down, gear 101 and rack-plate 305 engage each other, now gear 101 is rotated counterclockwise, the relative inner ring 1033 in unilateral bearing 103 outer ring 1031 is in not usable rotational direction, (horizontal plane direction cut by two groups, front and back roller for running apparatus assembly see so roller for running apparatus assembly 100 rotates counterclockwise, or have treadmill belt 204 between the two, plane on it) all the time along with people at the double, quick march side move in the opposite direction.
When body builder's both feet leave the moment of running platform assembly 200 again, return spring assembly 307 makes running platform assembly 200 moves, now gear 101 turns clockwise, the relative inner ring 1033 in unilateral bearing 103 outer ring 1031 is in usable rotational direction, and roller for running apparatus assembly 100 neither rotates clockwise, also do not rotate counterclockwise; But due to the effect of upper Secondary Shocks, if roller for running apparatus assembly 100 now creates inertia force, this inertia force has exceeded frictional resistance, roller for running apparatus assembly 100 by inertia force drive be free to rotate counterclockwise, treadmill belt 204 still to people at the double, quick march side move in the opposite direction; Move in circles with this.
Concrete computational process is as follows:
If human body impulsive force is F, then act on 4 gears 101 (or friction pulley, symmetrical) tangent line (do not consider mechanical loss for F with joint efforts, lower same), then have: the stressed P=F × r/R of treadmill belt 204, there is the frictional force f=F × μ between jackshaft 210 and plastic sheath 211 simultaneously.
Wherein, r is the radius of gear 101; R is the radius of roller for running apparatus 104.
The ratio of r/R is larger, then P is more close to F; Being greater than 1 when the ratio of r/R is that then P is greater than F;
μ---coefficient of friction, for sliding friction, μ is less than 1 forever; Coefficient of friction for rolling bearing is lower.So P > f, treadmill belt to deviating from people at the double, quick march, move by direction.
As shown in Figure 12 and Figure 13, also treadmill belt 204 can not be used in embodiment 1.Particularly,
