Fig. 1-Fig. 6 is referred to, the belt drive unit of the band tensioning that the present invention is provided, its specific work process is as follows：
In normal work, the advance low rate start of driving shaft 11 simultaneously drives drive 2 to rotate, by the ring ear of driving wheel 2
Portion 22 drives arrangement of clutch 4 to rotate, due to not being using being directly connected to, but by driving wheel 12 when driving wheel 12 and driving shaft 11
It is fixed on drive plate 2 by drive wheel bearing 3, when drive plate 2 is improved constantly with the velocity of rotation of driving shaft 11, and reaches one
After constant speed degree, arrangement of clutch 4 is expanded outwardly by centrifugal force, makes spring 42 then in the state that is stretched, and the rubber of clutch plate 41
Layer 411 is in contact with the medial surface of the ring portion 120 of driving wheel 12, and drives driving wheel 12 to rotate by frictional force, driving wheel 12
Then driven pulley 14 is driven to rotate by driving belt 16, so as to carry out transmission work；
When tensioning driving belt is needed, the velocity of rotation of driving shaft 11, band nutating disk 2 and arrangement of clutch are reduced first
4 speed of drive plate 41 reduction, and each drive plate 41 of arrangement of clutch 4, retract in the presence of the back stretch of spring 42, and
Depart from the frictional contact conditions with the ring portion 120 of driving wheel 12, so that driving wheel 12 runs out of steam and gradually stalls, then band
Dynamic driven pulley 14 and driven shaft 13 are stalled；Then, the handle 51 gripped in eccentric ring seat 5 rotates eccentric ring seat, using eccentric hoop
The eccentric structure feature of seat 51, changes the shaft core position of driven shaft 13, so change between driving wheel 12 and driven pulley 14 away from
From tensioning function is realized, after tensioning operation is completed, you can improve the velocity of rotation of driving shaft 11 again, and by foregoing mistake
Journey, drives driven pulley 14 and driven shaft 13 to rotate again, carries out tensioning operation without shutting down, it is not required that frequent starting power
Machine, you can to belt speedup, realizes the non-loaded startup of engine low speed.
The belt drive unit of the band tensioning that the present invention is provided, lightweight, compact conformation carries out tensioning work without shutting down
Industry, it is not required that frequent starting engine, you can to belt speedup, realizes the non-loaded startup of engine low speed.
Schematical specific embodiment of the invention is the foregoing is only, the scope of the present invention is not limited to.It is any
Those skilled in the art, the equivalent variations made on the premise of design of the invention and principle is not departed from and modification, all should
Belong to the scope of protection of the invention.
