A kind of Chain conveyer clutch
Technical field
The present invention relates to a kind of clutch.
Background technology
Clutch is that one can pass through various maneuverability patterns, there is when realizing main secondary part transmitting movement and power the device engaged with separation function, what current purposes was the widest is positive clutch and slip clutch two kinds, the driving part of both clutches requirement clutch and slave unit are on coaxial line, it is suitable for the transmission in same equipment, for the transmission between distinct device, owing to being difficult to proper alignment between equipment, driving part and slave unit have deviation on coaxial line, and existing clutch can not meet requirement.
Summary of the invention
The technical problem to be solved be to provide one both can transmission in same equipment, again can the Chain conveyer clutch of transmission between different devices.
The technical scheme is that a kind of Chain conveyer clutch, including slave unit and driving part, slave unit is driven sprocket, and driving part includes drive sprocket, driving shaft, tightener sprocket, rotating shaft, driving-chain, support plate, electronic screw putter;Described support plate is provided with installing hole I, installing hole II and supporting rail, driving shaft may be rotatably mounted in the installing hole I of support plate, rotating shaft may be rotatably mounted in the installing hole II of support plate, drive sprocket is fixedly mounted on driving shaft, tightener sprocket is fixedly mounted in rotating shaft, driving-chain is arranged on drive sprocket and tightener sprocket, electronic screw putter is arranged on support plate, electronic screw putter promotes support plate to rotate around driving shaft, making driving-chain engage with driven sprocket, the roller of site of engagement driving-chain is clipped between driven sprocket and the supporting rail of support plate.
As a modification of the present invention, described driving shaft is to be arranged in the installing hole I of support plate by rolling bearing.
As the another kind of improvement of the present invention, described rotating shaft is to be arranged in the installing hole II of support plate by rolling bearing.
The Chain conveyer clutch of the present invention is so work, clutch in conjunction with time, starting electronic screw putter promotes support plate to rotate around driving shaft, the driving-chain being arranged on drive sprocket and tightener sprocket together rotates with support plate, the roller of driving-chain is squeezed in the teeth groove of driven sprocket by the supporting rail of support plate, driving-chain is made to engage with driven sprocket, electronic screw putter stop motion, owing to screw putter has auto-lock function, after electronic screw putter stop motion, driving-chain and driven sprocket energy positive engagement, pass to driven sprocket by the power of driving shaft;During clutch separation, electronic screw putter anti-phase motion, pull support plate to rotate around driving shaft, driving-chain separates with driven sprocket, clutch separation.
The Chain conveyer clutch of the present invention, slave unit is driven sprocket, driving part includes drive sprocket, driving shaft, tightener sprocket, rotating shaft, driving-chain, support plate, electronic screw putter, rotated around driving shaft by electronic screw putter push-and-pull support plate, the driving-chain being arranged on drive sprocket and tightener sprocket is made to engage with driven sprocket or separate, realize clutch function, the sprocket of the energy-conservation embedding driven sprocket of chain that this clutch mode only requires driving-chain, owing to the inner width of driving-chain is sized larger than sprocket wheel facewidth size, and sprocket wheel flank has chamfering, the chain link of driving-chain is easier to embed the sprocket of driven sprocket, it is not required for driving part strictly to align with slave unit, therefore the Chain conveyer clutch of the present invention both can transmission in same equipment, again can transmission between different devices.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described, but embodiment is not intended that limitation of the present invention.
Fig. 1 to Fig. 5 illustrates the structure chart of a kind of Chain conveyer clutch embodiment of the present invention, referring to Fig. 1, this Chain conveyer clutch includes slave unit and driving part, slave unit is driven sprocket 8, and driving part includes drive sprocket 1, driving shaft 2, tightener sprocket 6, rotating shaft 7, driving-chain 5, support plate 3, electronic screw putter 4;
Referring to Fig. 2, support plate is provided with installing hole I 10, installing hole II 11 and supporting rail 12;
Referring to Fig. 3, driving shaft 2 is arranged in the installing hole I of support plate 3 by rolling bearing 13;Drive sprocket 1 is fixedly mounted on driving shaft 2 by flat key 14;
Referring to Fig. 4, rotating shaft 7 is arranged in the installing hole II of support plate 3 by rolling bearing 15, and tightener sprocket 6 is fixedly mounted in rotating shaft 7 by flat key 16;
Referring to Fig. 1 and Fig. 5, driving-chain 5 is arranged on drive sprocket 1 and tightener sprocket 6, electronic screw putter 4 is arranged on support plate 3 by bearing pin 9, electronic screw putter 4 promotes support plate 3 to rotate around driving shaft 2, making driving-chain 5 engage with driven sprocket 8, the roller of site of engagement driving-chain 5 is clipped between the supporting rail 12 of driven sprocket 8 and support plate 3.
The Chain conveyer clutch of the present invention in conjunction with time, starting electronic screw putter 4 promotes support plate 3 to rotate around driving shaft 2, the roller of driving-chain 5 is squeezed in the teeth groove of driven sprocket 8 by the supporting rail 12 on support plate 3, making driving-chain 5 engage with driven sprocket 8, the power of driving shaft 2 passes sequentially through drive sprocket 1, driving-chain 5 passes to driven sprocket 8;During clutch separation, electronic screw putter 4 anti-phase motion, pull support plate 3 to rotate around driving shaft 2, driving-chain 5 separates with driven sprocket 8, clutch separation.
