As preferably, described bevel gear rotating shaft key is connected to axis hole one end of sleeve pipe, and be communicated with at the other end of axis hole and be provided with splined hole, hand-operated rotating shaft is slidably connected in splined hole by external splines interworking.Hand-operated rotating shaft is connected with sleeve pipe by spline, connects safe and reliable, splits simple and convenient.
As preferably, described hand-operated rotating shaft is rotatably connected on body, and on body sliding plug can the arming pin of apical grafting on hand-operated rotating shaft outer ring surface.By arranging arming pin apical grafting on hand-operated rotating shaft outer ring surface, hand-operated rotating shaft axial float can be avoided, improving safety reliability when using.
On the annular hand-operated rotating shaft that can be arranged on close sleeve pipe from keyway, as more preferably, the outer ring surface of described hand-operated rotating shaft is provided with the annular side by side corresponding with arming pin and joins keyway with annular from keyway, annular is wherein joined on the hand-operated rotating shaft that keyway is located near sleeve pipe, and the top of arming pin is connected to annular and joins keyway or annular from keyway.Keyway is joined with annular from keyway by arranging annular on the outer ring surface of hand-operated rotating shaft, the top of arming pin is connected to annular and joins keyway with annular from keyway, when hand-operated rotating shaft and sleeve pipe are by spline joint, the top of arming pin is connected to annular and joins in keyway, when hand-operated rotating shaft is separated with the splined hole on sleeve pipe, the top of arming pin is connected to annular from keyway, and chocking construction is simple and reliable; When annular joins one end that keyway is positioned at close sleeve pipe, annular when being positioned at the other end away from sleeve pipe from keyway, need move to sleeve pipe when hand-operated rotating shaft is separated with the splined hole on sleeve pipe, namely the external splines of hand-operated rotating shaft end is positioned at the axis hole of sleeve pipe, shorten the axial space of clutch mechanism thus, make its overall structure compact and reasonable more.
As more preferably, the hand-operated rotating shaft corresponding with described sleeve pipe is set with Compress Spring and split washer, one end apical grafting of Compress Spring is on body end face, and the other end apical grafting is on split washer.By arranging Compress Spring on hand-operated rotating shaft, by Compress Spring, hand-operated rotating shaft is automatically reset.
As preferably, the hand-operated rotating shaft outboard end relative with described sleeve pipe is provided with handwheel.Hand-operated rotating shaft is facilitated to rotate by arranging handwheel.
Therefore, a kind of clutch mechanism of the present utility model has following advantage: utilize existing technique and existing machinery structure, when not increasing cost and technology difficulty by before engaging and disengaging gear change axial motion into, effectively reduce space, 1/3rd are reduced with the final controlling element volume of same torsion, fuselage weight alleviates 1/4th, and to the pressure of pipeline and infringement after reducing, effectively extends the working life of valve and pipeline.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of a kind of clutch mechanism of the utility model.
Embodiment:
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
As shown in Figure 1, a kind of clutch mechanism of the present utility model, the main shaft 1 of valve can be opened or closed when comprising rotation, on main shaft 1, key is connected to drive bevel gear 2, drive bevel gear 2 engages driven wheel of differential 3, wherein the bevel gear rotating shaft 4 of driven wheel of differential 3 correspondence is rotatably connected on bearing support by needle bearing, the bevel gear rotating shaft 4 outboard end key relative with driven wheel of differential 3 is connected in the axis hole 51 of one end of sleeve pipe 5, be splined hole 52 at the other end of axis hole 51, the large footpath of splined hole 52 is less than the internal diameter of axis hole 51, in splined hole 52, interworking is connected to and can slides axially, and the hand-operated rotating shaft 6 that sleeve pipe 5 can be driven to rotate, hand-operated rotating shaft 6 end corresponding with splined hole 52 is with external splines 61, hand-operated rotating shaft 6 is slidably connected in splined hole 52 by external splines 61 interworking, hand-operated rotating shaft 6 is wherein rotatably connected on body 7 and also can relatively horizontally slips by body 7, sliding plug vertical on body 7 one can the arming pin 8 of apical grafting on hand-operated rotating shaft 6 outer ring surface, the annular corresponding with arming pin 8 that have arranged side by side on the outer ring surface of hand-operated rotating shaft 6 joins keyway 9 with annular from keyway 10, annular wherein joins the left-hand end that keyway 9 is positioned at close sleeve pipe 5, annular from the right-hand end of keyway 10 near sleeve pipe 5, during arming pin 8 slide downward, its top is connected to annular and joins keyway 9 or annular from keyway 10, the hand-operated rotating shaft 6 corresponding with sleeve pipe 5 side overlaps and is filled with Compress Spring 11 and split washer 12, one end apical grafting of Compress Spring 11 is on body 7 end face, the other end apical grafting is on split washer 12, hand-operated rotating shaft 6 outboard end relative with sleeve pipe 5 is equipped with handwheel 13.
