Wall, forms the annular groove accommodating chain between two sprocket wheel walls.
Further, the bottom of described annular groove is along driven sprocket axial direction level, said two chain
The cross section at axis direction of wheel wall and annular groove presents " recessed " type.
Further, the bottom of described annular groove has the support projection for contacting chain hinge pin.
Further, the width that described support is protruding matches with the spacing of the inner plate of described chain.
Further, described support is protruding and has, between described sprocket wheel wall, the appearance board slot accommodating carrier bar.
Further, the width of described appearance board slot matches with the thickness of link plates of described chain.
Further, the boss face that described support is protruding is not less than chain with the difference in height of annular groove bottom surface
The height of carrier bar.
The beneficial effects of the utility model are: drive sprocket is toothed sprocket, and described driven sprocket is anodontia
Sprocket wheel, described driven sprocket has the sprocket wheel wall formed by driven sprocket main body, and sprocket wheel wall is along driven sprocket
Both ends of the surface extend and are formed two sprocket wheel walls, form the annular groove accommodating chain between two sprocket wheel walls.
In native system, driven sprocket is without tooth sprocket, and damaging occur in tooth or axle such as driven sprocket, and chain is driven
Sliding friction is become from rolling friction, even if damaging occurs in driven sprocket does not also interfere with sprocket wheel biography on sprocket wheel
Dynamic system worked well, reduces fault rate greatly, reduces the phenomenon generation that transmission is shut down.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in detail.
Embodiment 1
Shown in Fig. 1, Fig. 2, the present embodiment provides a kind of sprocket drive system, including drive sprocket
100, driven sprocket 300 and chain 200, drive sprocket 100 and driven sprocket 300 outer wall are set with chain
Bar 200, drive sprocket 100 is toothed sprocket, and driven sprocket 300 is without tooth sprocket, driven sprocket 300
Having the sprocket wheel wall 310 formed by driven sprocket 300 main body, sprocket wheel wall 310 is along driven sprocket 300 liang
End face extends and is formed two sprocket wheel walls 310, is formed and accommodate chain 200 between two sprocket wheel walls 310
Annular groove.
Concrete, unlike the prior art, the sprocket drive system proposed in the present embodiment is had tooth by one
Drive sprocket 100 and an anodontia driven sprocket 300 directly coordinate, it is not necessary to turn to sprocket wheel, with
Time solve transfer motion power loss that the bending of chain 200 in prior art causes, transmission efficiency declines, this
System uses the power source of a lower-wattage can realize the action of whole system.In the present embodiment, nothing
Two end faces of tooth sprocket extend the main body of formation circular end face, this end face and driven sprocket 300 to around
One-body molded, this end face diameter is more than the diameter of driven sprocket 300 mid portion so that two end faces are dashed forward
Go out to be formed sprocket wheel wall 310.
Chain 200 is connected by tooth with drive sprocket 100, when chain 200 is centered around driven sprocket 300
Time upper, chain 200 is fastened between two sprocket wheel walls 310.In the ordinary course of things, power is by drive chain
Wheel 100 is transferred to chain 200, then is provided sliding friction by driven sprocket 300.At driven sprocket 300
When bearing damage, driven sprocket 300 cannot rotate, driven sprocket 300 and chain 200 are by original rolling
Friction becomes sliding friction, slightly increases with frictional force, but drive system entirety still can normally work.
As preferably, the bottom of annular groove is along driven sprocket 300 axial direction level, two sprocket wheels
The cross section at axis direction of wall 310 and annular groove presents " recessed " type, as shown in Figure 2.Annular is recessed
The bottom surface of groove is preferably smooth, to reduce frictional force during sliding friction.
As preferably, it is protruding that the bottom of annular groove has the support for contacting chain 200 bearing pin
320.This support projection 320 plays and increases the effect of contact area between chain 200 and driven sprocket 300,
On the one hand prevent driven sprocket 300 and chain 200 from skidding under the friction condition that moves in turn, on the other hand, hold
Torr protruding 320 plays the effect of support chain 200 bearing pin, it is to avoid carrier bar compressive deformation.
As preferably, the shapes and sizes of support projection 320 should coordinate with chain 200, i.e. support is convex
Play the width of 320 to match with the spacing of the inner plate of chain 200.Support protruding 320 and sprocket wheel wall 310
Between have accommodate carrier bar appearance board slot 330.Hold the width of board slot 330 and the thickness of link plates of chain 200
Match.The boss face of support projection 320 is not less than chain 200 with the difference in height of annular groove bottom surface
The height of carrier bar.Agree with reaching the perfection of chain 200 and driven sprocket 300.Similarly to the prior art,
Installing hole 340 is offered in the middle of driven sprocket 300.
Sprocket drive system in the present embodiment, in mattress transport field, is particularly suitable for and pneumatic power source
Collocation.
Implement profit 2
Sprocket drive system in the present embodiment is similar with the sprocket drive system in embodiment 1, distinguishes
In from the shape of wheel sprocket.
In some chain gear transmission, chain 200 is flyer chain 200, corresponding driven sprocket 300
Annular groove should be smooth, it is not necessary to support projection 320, to adapt to the shape of chain 200.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art,
According to thought of the present utility model, may be made that many changes in specific embodiments and applications,
As long as these changes are without departing from design of the present utility model, belong to protection domain of the present utility model.
