Abstract
The utility model relates to a bidirectional automatic clutching mechanism. The symmetrical positions at both sides of the connecting line of the shaft center of a drive shaft and a driven shaft are provided with a clutching gear and wheel shafts of the clutching gear which have the same parameter; two holes of the wheel shafts are two concave arc-shaped shaft holes; center line of the two holes of the wheel shafts can use the shaft center of the drive shaft as the center of a circle; the sum of the reference radius of the drive gear and a clutching gear can be used as the radius of the two holes of the wheel shafts; the drive shaft is also provided with a torsion spring; both ends of the torsion spring respectively and tightly are fixed at two clutching gear shafts; the torsion spring is used for the resetting operation; the utility model has simple structure; the utility model can conveniently and reliably realize the bidirectional automatic clutching operation of a drive wheel and a driven wheel in a gear transmission component; the driven wheel can be disengaged from the clutching mechanism to carry out the independent rotation; the utility model is especially suitable for the electric and manual dual-purpose control so as to do the bidirectional movement.
Description
The utility model relates to automatic clutch, relates in particular to a kind of two-way automatic clutch mechanism.
Existing two-way automatic clutch mechanism, structure more complicated, especially follower can not be thrown off the clutch mechanism independent rotation, not only needing not to be suitable for electronic but also to need manual controlled motion spare to carry out making bidirectional automatic clutch in the five metals commodity of forward and reverse motion." bidirectional automatic clutch " as Chinese patent CN2091381U bulletin.
The purpose of this utility model is to remedy the deficiencies in the prior art, proposes a kind of two-way automatic clutch mechanism.
The purpose of this utility model is achieved by the following technical programs.
This two-way automatic clutch mechanism comprises that reference radius is respectively R
1, R
2Driving and driven gear and master and slave moving axis thereof, it is characterized in that being provided with the identical reference radius of parameter at master and slave moving axis axial connecting line bilateral symmetry place is R
3A clutch gear and radius thereof be R
4Wheel shaft, and the two-wheeled axis hole is that two center lines are to be the center of circle and with R with the driving shaft axle center
1With R
3Sum is the concave arc shape axis hole of the camber line of radius, is the center of circle and with R with the point that is the clutch gear Outside radius with master and slave moving axis axial connecting line perpendicular distance on the axis hole center line
4For the circular arc of radius is the lower limit circular arc of concave arc shape axis hole inboard, with the axis hole center line with the driven shaft axle center be the center of circle and with equal, greater than R
2With R
3Sum is that the intersection point of the camber line of radius is respectively the center of circle and with R
4For the circular arc of radius is the upper limit circular arc of concave arc shape axis hole inboard and the circular arc in the outside, is fastened on two clutch gear axles respectively and makes it when driving wheel stops operating, reset at the torsion spring that axis hole departs from inboard neutral position respectively also being provided with two ends on the driving shaft.
The utility model is novel, simple in structure, can realize the two-way automatic clutch of driven wheel in the gear-driven assembly easily and reliably, and follower can be thrown off the clutch mechanism independent rotation, especially be suitable for not only needing electronic but also need manual controlled motion spare to carry out the five metals commodity of bidirectional-movement, make bidirectional automatic clutch as power window, electrically driven curtain, electronic children and car for disabled persons etc.
Accompanying drawing is a composition schematic representation of the present utility model.
The contrast accompanying drawing is also made an explanation to the utility model in conjunction with the embodiments below.
The electronic sliding door bidirectional automatic clutch of embodiment
This bidirectional automatic clutch comprises that reference radius is respectively R
1=3 centimetres, R
2=3 centimetres driving and driven gear 1,2 and master and slave moving axis 3,4 thereof, driving gear 1 is meshed with motor output shaft through the reduction gear transmitting assemblies, driven gear 2 be fastened on same driven shaft 4 as the sliding door return pulley, omit gearing down assembly, motor, return pulley and gear-box in the accompanying drawing and do not draw, it is characterized in that being provided with the identical reference radius of parameter at master and slave moving axis 3,4 axial connecting line bilateral symmetry places is R
3=1.6 centimetres clutch gear 5,6 and radius thereof are R
4=0.3 centimetre wheel shaft 7,8, and the two-wheeled axis hole is that two center lines are to be the center of circle and with R with driving shaft 3 axle center
1+ R
3=R
5=4.8 centimetres is the concave arc shape axis hole 9,10 of the camber line of radius, its medial and lateral radius of arc R
6=R
4=0.3 centimetre, be fastened on two clutch gear axles 7,8 respectively and make it when driving wheel 1 stops operating, reset at the torsion spring 12 that axis hole 9,10 departs from inboard neutral position respectively also being provided with two ends on the driving shaft 3.Clutch gear axle 7,8 is in concave arc shape axis hole 9,10 arbitrary positions, clutch gear 5,6 all is meshed with driving gear 1, at concave arc shape axis hole 9,10 inner sides, clutch gear 5,6 all is meshed with driving and driven gear 1,2, and in concave arc shape axis hole 9,10 outsides with depart from inboard position, 5,6 of clutch gears are meshed with driving gear 1, and are separated with driven gear 2.When motor drives driving gear 1 rotates clockwise, clutch gear 5,6 counterclockwises rotate, its wheel shaft 7,8 overcomes torsion spring 12 under the effect of engaging friction power and rotating force torsion slides onto the medial and lateral circular arc near concave arc shape axis hole 9,10 respectively, driven gear 2 is meshed with clutch gear 5 with clutch gear 6 reliable separation and does and driving gear 1 rotation clockwise in the same way, and the sliding door return pulley drives door and opens.And when motor oppositely drove driving gear 1 inverse clock and rotates, driven gear 2 was meshed with clutch gear 6 with clutch gear 5 reliable separation and makes counterclockwise and rotate, and the sliding door return pulley drives closes.When motor stops operating, driving gear 1 stops operating, the wheel shaft 7,8 of clutch gear 5,6 resets at concave arc shape axis hole 9,10 respectively and departs from inboard neutral position under the twisting force of torsion spring 12, driven gear 2 is thrown off can make independent rotation, take manually to control the return pulley translation, can the switch sliding door.
