Embodiment
Below in conjunction with accompanying drawing, the utility model is further described: as Figure 1-3; Cone pulley type band transmission buncher, by taper cone pulley 1, fixed sheave 2, removable sheave 3, two-sided transmission band 4, multinomial connecting rod 5, equal armed lever 6, slide plate 7, T-shaped connecting rod 8, equal armed lever axle 9, fixed groove wheel carrier 10, spacing fixing frame 11, rotary extension axle 12, speed control rod 13, composition.Slide plate frame 14 is characterized in that: 4, two-sided transmission band is overhanged a rectangle by four fixed sheave 2, fixed sheave 2 is fixedly connected on body by fixed groove wheel carrier 10, two taper cone pulleies 1 are arranged on the outside of two-sided transmission band 4 with equidirectional, four removable sheaves 3 are arranged symmetrically on the point of contact at 180 degree half cycle diameter two ends of two taper cone pulleies 1, make two-sided transmission band 4 on two taper cone pulleies 1, can respectively maintain all the time half cycle working surface; The inclined-plane of two-sided transmission band 4 coordinates with taper cone pulley 1, edged surface coordinates with fixed sheave 2 and removable sheave 3; Multinomial connecting rod 5 one end are movably connected on taper cone pulley 1, and the other end is movably connected on equal armed lever 6, and multinomial connecting rod 5 middle parts are fixedly connected with slide plate frame 14, and slide plate frame 14 two ends connect slide plate 7; Equal armed lever 6 middle cover are contained on equal armed lever axle 9, the upper end floor beam of T-shaped connecting rod 8 is installed in slide plate 7, T-shaped connecting rod 8 lower ends connect on removable sheave 3, slide plate 7 is arranged in parallel with the inclined-plane of taper cone pulley 1, T-shaped connecting rod 8 is arranged on body by spacing fixing frame 11, because slide plate 7 is parallel with the inclined-plane of taper cone pulley 1, thus can control removable sheave 3 remain at taper cone pulley 1 180 degree half cycle diameter two ends point of contact on.Equal armed lever axle 9 is controlled equal armed lever 6 can only control taper cone pulley 1 and multinomial connecting rod 5 centered by equal armed lever axle 9.Fixed groove wheel carrier 10 is fixed on body fixed sheave 2 is rotated a fixed position.Spacing fixing frame 11 is fixed on and on body, limits multinomial connecting rod 5 and T-shaped connecting rod 8 can only shuttle back and forth and slide in its hole.Rotary extension axle 12 one end connect power or load, and the other end is fixed on taper cone pulley 1, can stretch and transmission rotating force in centre.Speed control rod 13 under external force push-and-pull equal armed lever 6 drives taper cone pulley 1 and slide plate 7 to carry out speed governing.
1 one relative two-sided transmission bands 4 of two taper cone pulleies do and expand circular movement another relative two-sided transmission band 4 and do and dwindle circular movement, move in opposite directions when equidistant with same uniform velocity at relative two-sided transmission band 4 synchronous cross of two taper cone pulleies 1 simultaneously, the half cycle working surface of two-sided transmission band 4 on two taper cone pulleies 1 expands identical with the absolute value of the half cycle numerical value dwindling, because two taper cone pulleies, 1 upper half working surface expands and the variation of the half cycle numerical value that dwindles, the variation that has produced bull wheel band steamboat or steamboat band bull wheel, realizes speed change.
One end of two taper cone pulleies 1, as input and output side, is provided with rotary extension axle 12.The other end is flexibly connected one end of multinomial connecting rod 5.Four fixed sheave 2 overhang a rectangle 4, two-sided transmission band, make the two-sided transmission band 4 can only be four fixed sheave 2 cocycles, when two taper cone pulleies 1 are from install in outside, two-sided transmission band 4 respectively has again a half cycle working surface under the control of T-shaped connecting rod 8, removable sheave 3, slide plate 7, multinomial connecting rod 5 on two taper cone pulleies 1.When speed control rod 13 is when push-and-pull equal armed lever 6 drives taper cone pulley 1 and slide plate 7 to carry out speed governing under external force, the half cycle working surface size of two-sided transmission band 4 on two taper cone pulleies 1 changes.As shown in Figure 1 in the time that speed control rod 13 is subject to external force push-and-pull equal armed lever 6, multinomial connecting rod 5 will drive taper cone pulley 1 left and right operation, one of them taper cone pulley 1 moves left, because two-sided transmission band 4 moves in fixed sheave 2, can not left and right deviation, so the half cycle working surface of two-sided transmission band 4 on taper cone pulley 1 becomes large.Another moves to the right, because two-sided transmission band 4 moves in fixed sheave 2, can not left and right deviation, and the half cycle working surface of two-sided transmission band 4 on taper cone pulley 1 diminishes.And the half cycle working surface of two-sided transmission band 4 on two taper cone pulleies 1 becomes large identical with the numerical value diminishing.Multinomial connecting rod 5 two other parts of while are controlled T-shaped connecting rod 8 with slide plate 7 and are driven removable sheave 3 upper and lower, coordinate two-sided transmission band 4 on taper cone pulley 1, to remain half cycle working surface.Due to the variation of two-sided transmission band 4 on two taper cone pulleies, 1 half cycle working surface, in the time of the 1 stable input of a taper cone pulley, the rotational speed that another taper cone pulley 1 is exported changes.
Two taper cone pulleies 1 also can install in opposite directions or be positioned on inner side but two-sided transmission band 4 and fixed sheave 2 all will change.1 two of described taper cone pulleies, fixed sheave 2 is 0-n, minimum 4 of removable sheave 3, exceed four for auxiliary.
