Abstract
The utility model relates to a double-arm hinged variable center distance chain-drive mechanism which is especially suitable for the occasion that center distance of the chain-drive needs online varying. One end of a drive hinged arm 4 is provided with a driving sprocket 3 which is hinged on a driving shaft 2, and the other end is provided with a transition sprocket 6 which is hinged with a driven hinged arm 7. The other end of the driven hinged arm is provided with the driven sprocket 9 which is hinged on a driven shaft 10. The driving shaft and the driven shaft are respectively assembled on a machine base 1 and an elevating table 12, and the elevating table is lifted up and down through a cylinder 18. The utility model adopts a crank block mechanism and cylinder drive, and thus the power drive of on-line varying of the centre distance can be completed. The action is rapid, the on-line variation of the central distance is big, and the chain does not need adjusting.
Description
The utility model relates to a kind of hinged change centre distance of chain drive, especially both arms chain drive that is applicable to the online variation occasion of chain-driven centre distance needs.
Under specific situation, need be between two transmission shafts of the online variation of centre distance transferring power.At present, the variation adjustment of chain-driven centre distance is to adopt one side sprocket shaft to fix, and the another side sprocket shaft is fixed in the sliding-groove by screw and briquetting, can adjust this sprocket shaft behind the slack adjuster and slide along groove, tightens screw after adjusting to the right place again.This regulative mode, its centre distance variable quantity is little, adjusts inconveniently, need adjust the tensioning of chain at any time with the variation of centre distance, and centre distance changes and can not onlinely carry out.
The purpose of this utility model provides a kind ofly need not adjust chain tension, and the bigger hinged change centre distance of the both arms chain drive of the online variable quantity of centre distance.
Concrete scheme of the present utility model is: (A), driving shaft is assemblied in the support outside through fixed base, is provided with drive sprocket on driving shaft; (B), driven shaft is provided with driven sprocket, driven shaft is assemblied on the self-powered platform by fitting seat; (C), initiatively articulated jib one end is articulated on the driving shaft, the other end and driven articulated jib one is hinged, and the other end of driven articulated jib is hinged on the driven shaft, in master and slave articulated jib connection place duplex transition sprocket wheel is housed; (D), between drive sprocket and the transition sprocket wheel, be fitted with chain between transition sprocket wheel and the driven sprocket; (E), self-powered platform is installed in the upper surface of support through guide holder, the axis of guide and limiting stopper, self-powered platform stretches in the support, connects with cylinder through the cylinder joint.
The utility model has been owing to adopted slidercrank mechanism and cylinder transmission, thereby the power that can finish the online variation of centre distance transmits.It is compared with existing similar technology, and action is quick, and the online variable quantity of centre distance is big, and need not adjust the tensioning of chain.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is an overall structure schematic representation of the present utility model.
As shown in Figure 1: the utility model is by fixed base 1, driving shaft 2, drive sprocket 3, initiatively articulated jib 4, chain 5, transition sprocket wheel 6, driven articulated jib 7, chain 8, driven sprocket 9, driven shaft 10, fitting seat 11, self-powered platform 12, guide holder 13, the axis of guide 14, cylinder joint 15, spacing fast 16, support 17 and cylinder 18 are formed.Structure outline of the present utility model is: (A), driving shaft 2 is assemblied in support 17 outsides through fixed base 1, is provided with drive sprocket 3 on driving shaft 2; (B), driven shaft 10 is provided with driven sprocket 9, driven shaft 10 is assemblied on the self-powered platform 12 by fitting seat 11; (C), initiatively articulated jib 4 one ends are articulated on the driving shaft 2, the other end and driven articulated jib 7 one is hinged, and the other end of driven articulated jib 7 is hinged on the driven shaft 10, in master and slave articulated jib connection place duplex transition sprocket wheel 6 is housed; (D), between drive sprocket 3 and the transition sprocket wheel 6, be fitted with chain 5 or 8 between transition sprocket wheel 6 and the driven sprocket 9; (E), self-powered platform 12 is installed in the upper surface of support 17 through guide holder 13, the axis of guide 14 and limiting stopper 16, self-powered platform 12 stretches in the support 17, connects with cylinder 18 through cylinder joint 15.
The utility model is performed such work: when needs self-powered platform 12 online lifting actions, initiatively articulated jib 4, driven articulated jib 7 and self-powered platform 12 form slidercrank mechanism, drive self-powered platform 12 by cylinder 18 by cylinder joint 15 and press need of work realization lifting action; By the power on the driving shaft 2 that is fixed in support 17 outsides, can be sent on the driven sprocket 9 along drive sprocket 3, chain 5, transition sprocket wheel 6, chain 8, thus the needs of the online variation of realization centre distance.
