The synchrodrive and the tightening device of two roller spacings of scalable of the present utility model comprise the upper roller that is arranged on the top roll power wheel, are arranged on the lower roller on the lower roll power wheel; The lower roll power wheel is arranged on and can moves with on the spacing control apparatus that changes upper roller and lower roller spacing with respect to upper roller; Top roll power wheel and lower roll power wheel are by chain or strap drive, so that formation upper roller and lower roller locking phase are to interlock; It also comprises the stretching device that makes described chain or be with in tension.
The utility model makes two rollers produce synchronous interaction by chain-driving (or strap drive), directly make lower roller move up and down the spacing that just can regulate upper roller and lower roller, and guarantee that two rollers remain synchronous main gear state in the spacing adjustable extent by spacing control apparatus (as cylinder).Regulating chain (or driving band) the degree of tightness variation that lower roller moves up and down generation, is the normal smooth running that guarantees driving system, also must dispose the stretching device that makes described chain or be with in tension.The utility model can guarantee that two rollers, two rollers in the spacing adjustable extent remain the synchronous in opposite directions main gear state of pulsation-free.
Described stretching device is varied, for example comprise the tension wheel that contacts with described chain or band, the tension wheel shaft of suit tension wheel is slidingly arranged on the permanent seat, makes tension wheel compress the elastic element of described chain or band (as spring, cylinder or hydraulic actuating cylinder or the like) when being provided with in normality between permanent seat and the tension wheel shaft.
For above-mentioned synchrodrive and tightening device, it also comprises motor reducer, be arranged on the motor reducer power wheel on the output shaft of motor reducer, described chain or band pass motor reducer power wheel, top roll power wheel, lower roll power wheel, tension wheel successively, form osed top chain or strap drive.
For above-mentioned synchrodrive and tightening device, S-shaped walking between described chain or band top roll power wheel and the lower roll power wheel.
For above-mentioned synchrodrive and tightening device, the lower roll power wheel rotates and is arranged on the lower roller bearing seat assembly, and lower roller bearing seat assembly is arranged on the spacing control apparatus.
The utility model is specially adapted to the higher occasion of temperature if adopt chain-driving.If adopt synchronous strap drive, be specially adapted to the not too high occasion of temperature.
Description of drawings
Fig. 1 is the synchrodrive and the tightening device scheme drawing of the utility model scalable roller spacing.
Fig. 2 is the stretching device scheme drawing among Fig. 1.
The specific embodiment
Further specify the specific embodiment of the present utility model below in conjunction with accompanying drawing, but not as the qualification to the utility model content.
As shown in Figure 1, the utility model comprises upper roller 1, lower roller 4, lower roller bearing seat assembly 5 moving up and down and connect firmly cylinder 10, chain wheel driving mechanism, automatic tensioning mechanism 6 on it only.
Referring to Fig. 2, automatic tensioning mechanism 6 comprises movable idler sprocket 3, sprocket shaft 14, spring shaft 15, permanent seat 16, spring 17, spring housing 18.Wherein movable idler sprocket 3 usefulness sprocket shafts 14 are fixedly connected with spring shaft 15 upper ends.Spring 17 is enclosed within spring shaft 15 bottoms, and between the φ d of spring housing 18 inner bottom surfaces and spring shaft 15 end face, φ d size is greater than the middle footpath of spring 17, and spring 7 can extend or compression thereupon when spring shaft 15 moved up and down, and spring housing 18 is connected with permanent seat 16.Automatic tensioning mechanism 6 is contained on the machine by permanent seat 16.
Chain wheel driving mechanism comprises motor reducer 13, last roller chain 2, following roller chain 7, fixed tensioning wheel 8,9, chain 11.Chain 11 passes motor reducer sprocket wheel 12, fixed tensioning wheel 8, last roller chain 2, following roller chain 7, movable idler sprocket 3, fixed tensioning wheel 9 and motor reducer sprocket wheel 12 successively, form the osed top messenger chain, guaranteeing also can synchrodrive two roller under the situation that has the gap between upper roller 1 and the lower roller 4.
Referring to Fig. 1, the gap minimum between the roller up and down during work, lower roller 4 is positioned at the extreme higher position, and movable idler sprocket 3 also rises to the extreme higher position with chain tension automatically under the elastic force effect of spring 17.When needing to regulate two roller spacings, make the piston rod retraction of cylinder 10 by change-over valve, the lower roller bearing seat assembly 5 on it of being connected drive lower rollers 4 and down roller chain 7 move down apart from e to 7 ' position, simultaneously, the cylinder pulling force forces movable idler sprocket 3 to overcome to arrive after the automatic lowering distance c behind the elastic force that spring 17 makes progress by chain 11 and still can make chain 11 slack-free positions 3 '.After adjusting put in place, system still can guarantee pulsation-free synchrodrive state.
The utility model makes two rollers produce synchronous interaction by chain-driving (or strap drive), directly make lower roller move up and down the spacing that just can regulate upper roller and lower roller by cylinder 10, and guarantee that two rollers remain synchronous main gear state in the spacing adjustable extent by air operated control.
