Specific embodiment
The invention will be further described with reference to the accompanying drawing.
Referring to Fig. 1 and Fig. 2, Fig. 1 is a kind of stereoscopic schematic diagram of single-point clutch provided in an embodiment of the present invention, and Fig. 2 is
The schematic illustration of single-point clutch provided in an embodiment of the present invention.Single-point clutch provided in an embodiment of the present invention, including pass
Active toothed disk 4, driving fluted disc 6, piston body 8, cylinder block 10 and shaft 2, wherein the inner ring of driving fluted disc 6 has internal tooth, shaft 2
Outer wall there is external tooth, driving fluted disc 6, which is cooperated by the internal tooth with external tooth when couple with shaft 2, to be coupled, driving fluted disc 6
It can be moved and be coupled with shaft 2 by key, piston body 8 and cylinder block 10 are successively set on driving fluted disc 6 back to the one of transmission fluted disc 4
Side, cylinder block 10 are sleeved in shaft 2 by the first deep groove ball bearing 51, and piston body 8 and driving fluted disc 6 pass through the second deep-groove ball
Bearing 52 is sleeved in shaft 2, therefore, driving fluted disc 6 can be rotated with shaft 2, and cylinder block 10 and piston body 8 not with
Shaft 2 rotate；Meanwhile piston body 8 is slidably connected with cylinder block 10 by mutually chimeric annular groove and ring convex structure, ring convex
It is formed with ring cavity between end face and annular groove, the air inlet 41 being connected to ring cavity is offered on the outer peripheral surface of cylinder block 10, and described
Driving fluted disc 6 and the end face for being driven fluted disc 4 are equipped with mutually matched tartar tooth, the tartar that ring is set on the driving fluted disc 6
It is equipped with groove structure 15 at one at tooth, is equipped at one at the tartar tooth of the transmission fluted disc 4 and is matched with the groove structure
Bulge-structure 16, which is different from the shape of tartar tooth, and the camber ratio tartar tooth difference of protrusion is larger, because
This, the shape of rule can be both made in the tartar tooth in other places, be also possible to irregular shape；Drive fluted disc 6 is opposite to pass
The side of active toothed disk 4 is provided with reset spring 1, and the both ends of reset spring 1 offset with driving fluted disc 6 and baffle 3 respectively, and baffle
3 couple with shaft 2.
Driving fluted disc 6 whole relative to be driven the rotation of fluted disc 4 one it should be noted that " single-point clutch " of the invention refers to
In week, due to being alternately provided with only mutually matched groove structure and bulge-structure at one at tartar tooth, an only position
The two can be intermeshed, i.e., there are clutch unique positions to be driven property.As shown in Figure 6 and Figure 7, fluted disc 6 and transmission are driven
Tartar tooth on 4 end face of fluted disc be it is irregular, have and at only one protrusion and groove structure cooperation, ensure that clutch is
Single-point clutch.
Shaft 2 with the power unit of machine for being connected, by described when due to driving fluted disc 6 to couple with shaft 2
Tooth couples with the cooperation of external tooth 18, so, driving fluted disc 6 can be rotated together with shaft 2, it is also possible to which opposite shaft 2 is axial
It is mobile.Drive the connection between fluted disc 6 and shaft 2 can be with key connecting, it can be lead key, feather key or spline.
Piston body 8 with cylinder block 10 is slidably connected by mutually chimeric annular groove and the realization of ring convex structure, such as Fig. 2 institute
Show, in the present embodiment, ring convex are the structure in cylinder block 10, and annular groove is the structure on piston body 8.Certainly, other real
It applies in example, ring convex are exchanged also possible with annular groove, it can annular groove is designed as the structure in cylinder block 10, and ring convex are set
The structure being calculated as on piston body 8.
It is formed with ring cavity between the end face and annular groove of ring convex, in this way, being passed through pressed gas from the air inlet 41 of cylinder block 10
After, the pressed gas in ring cavity can make 8 complete cycle uniform force of piston body.It, can be in ring convex and ring in order to improve air-tightness
O-ring seal is set on sliding surface between slot.
As shown in Fig. 2, the inner ring of the second deep groove ball bearing 52 is mounted on piston body 8 in the present embodiment, fluted disc 6 is driven
It covers on the outer ring of the second deep groove ball bearing 52.In other examples, can also be arranged by opposite mode, i.e., by mutual
Mounting structure is changed, the inner ring of the second deep groove ball bearing 52 is mounted on driving fluted disc 6, and by 8 sets of piston body in the second zanjon
On the outer ring of ball bearing 52.
In the present embodiment, baffle 3 is fixed in shaft 2 by circlip 51.
The working principle of single-point clutch provided in an embodiment of the present invention is as follows:
A) pressed gas enters ring cavity from the air inlet 41 of cylinder block 10, pushes piston body 8, the second deep groove ball bearing 52 and driving
Fluted disc 6, after reset spring 1 compresses, driving fluted disc 6 is engaged with transmission fluted disc 4, and engagement state is as shown in Figure 3；
B) reset spring 1 stretches, and pushes driving fluted disc 6,8 return of the second deep groove ball bearing 52 and piston body, the gas in ring cavity
It is discharged from the air inlet 41 of cylinder block 10, driving fluted disc 6 is separated with transmission fluted disc 4, and discrete state is as shown in Figure 4.
As shown in Fig. 2, electricity generally is arranged on connection air machinery 30 and the pipeline of cylinder block 10 in specific practical application
Magnet valve 10, solenoid valve 10 are the two-position three way magnetic valve of one-in-and-one-out formula, and the interface as exhaust outlet of solenoid valve 10 generally connects
It is connected to silencer 20.
As shown in Figure 1, the outer surface of cylinder block 10 is provided with locking groove 102, the effect of locking groove 102 be to provide it is a kind of with
The clamping structure of rack resists the rotary motion trend of cylinder block 10.
Further, in order to resist the rotary motion trend of piston body 8, cylinder block 10 and piston body 8 are offered along turning
The location hole that the axis direction of axis 2 extends, positioning hole are equipped with positioning pin 7, as shown in Figure 2.
As shown in Fig. 2, positioning pin 7 is voluntarily withdrawn in order to prevent, offered on the outer peripheral surface of cylinder block 10 along shaft 2
The pin hole radially extended, the location hole in pin hole and cylinder block 10 penetrates through, and the elastic cylindrical pin 9 in pin hole passes through positioning pin 7
On through-hole.Positioning pin 7 is stopped by elastic cylindrical pin 9, because without voluntarily withdrawing, elastic cylindrical pin 9 relies on the bullet of itself
Property deformation swelling in the through-hole of positioning pin 7 and the pin hole of cylinder block 10, thus will not voluntarily withdraw.
