Description
Technical field
The present invention relates to electromechanical integration technology areas.More particularly, to a kind of mono-directional overrun clutch.
Background technology
Freewheel clutch is with the development of electromechanical integrated product and the basic part that occurs, it is to be used for prime mover and work
Make between machine or power transmits the important component with separation function inside machine between driving shaft and driven shaft.It is using it is main,
The velocity variations of secondary part or the transformation of direction of rotation have the device of voluntarily clutch function.
There are two types of common freewheel clutches, i.e. roller type and pawl type.Surmount direction again by it and can be divided into and is unidirectional and double
To two kinds.Roller type freewheel clutch is commonly used in the mechanical equipment to run at high speed for a long time, but the roller bearing table after long-time service
Surface wear is serious, when causing to bear compared with big load " skidding " and fail.Abrasion of the pawl-type overrunning clutch in transmission is smaller,
But it is more suited in the mechanical equipment of low speed rotation.
Invention content
Present invention aims at a kind of mono-directional overrun clutch is provided, existed with solving roller type and pawl-type overrunning clutch
Transmission is run at high speed for a long time compared with the wear failure problem in big load.
In order to achieve the goal above, the present invention uses following technical scheme：
A kind of mono-directional overrun clutch, including：
Driving wheel with internal tooth；
Driven wheel in the driving wheel；And
The tongue piece being arranged on the driven wheel corresponding with the internal tooth；
The side of the flank profil of the internal tooth tilts so that the chela that the driven wheel passes through the tongue piece and internal tooth with driving wheel
Close only relative rotation in one direction.
Preferably, when the driving wheel rotates counterclockwise, the driven wheel is driven to rotate counterclockwise；When the driving wheel
When rotating clockwise, the driven wheel is static.
Preferably, one end of the tongue piece is rotatably connected on the driven wheel, the other end by spring with it is described
Driven wheel connects.
Preferably, the rotatable angle of the tongue piece is 0 °~50 °.
Preferably, the driving wheel is provided with 6 internal tooths.
Preferably, the mono-directional overrun clutch further includes connecting to form inclusion cavity with the driving wheel mate
End cap；The driven wheel is located in the inclusion cavity.
Preferably, the end cap is connect by screw with the mate of the driving wheel.
Preferably, the spring is V-type spring.
Beneficial effects of the present invention are as follows：
Tongue piece formula mono-directional overrun clutch provided by the invention surmounts with common freewheel clutch is equally easy to implement；And
And to overcome in roller type freewheel clutch roller bearing easy to wear in use and lose for the tongue piece in tongue piece formula mono-directional overrun clutch
The defect of effect, and can be driven compared with big load.The tongue piece formula mono-directional overrun clutch of the present invention is simple in structure, easy to use, can grow
Time high speed uses and transmits the bearing capacity for improving freewheel clutch compared with big load.
Description of the drawings
Specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the principle schematic diagram of the mono-directional overrun clutch in the embodiment of the present invention.
Fig. 2 is the Standard figure of the mono-directional overrun clutch in the embodiment of the present invention.
Fig. 3 is the combining structure schematic diagram of the mono-directional overrun clutch in Fig. 2.
Description of the drawings：1- tongue pieces, 2- driven wheels, 3-V type springs, 4- driving wheels, 5- end caps.
Specific implementation mode
In order to illustrate more clearly of the present invention, the present invention is done further with reference to preferred embodiments and drawings
It is bright.It will be appreciated by those skilled in the art that specifically described content is illustrative and be not restrictive below, it should not be with this
It limits the scope of the invention.
The present invention provides a kind of mono-directional overrun clutch, which includes：Driving wheel with internal tooth；Position
Driven wheel in the driving wheel；And the tongue piece being arranged on the driven wheel corresponding with the internal tooth；The internal tooth
The side of flank profil tilt so that the driven wheel and driving wheel by the chelating of the tongue piece and internal tooth only in one direction
Relative rotation.When driven wheel and driving wheel relative rotation in one direction, that is, shows as driving wheel and rotates in this direction,
And driven wheel does not rotate, and surmounts to realize, driven wheel is equivalent to be detached with driving wheel.
Tongue piece formula mono-directional overrun clutch provided by the invention surmounts with common freewheel clutch is equally easy to implement；And
And to overcome in roller type freewheel clutch roller bearing easy to wear in use and lose for the tongue piece in tongue piece formula mono-directional overrun clutch
The defect of effect, and can be driven compared with big load.
With reference to figure 1- Fig. 3, the embodiment of the present invention provides a kind of mono-directional overrun clutch, including：Driven wheel 2, driving wheel 4, V
Type spring 3, tongue piece 1 and end cap 5.
The driving wheel 4 and driven wheel 3 of mono-directional overrun clutch by positioning key respectively in transmission system driving shaft and
Passive axis connection.Driven wheel is sleeved in 4 inner cavity of driving wheel, and driven wheel 3 and the 4 end face gaps Jian You of driving wheel can be movable relatively.It is main
There are six internal tooth on driving wheel 4, the teeth directional of six internal tooths is consistent.There are six tongue pieces 1 for installation on driven wheel 3, and tongue piece 1 can be around mounting hole
0 °~50 ° of central axis.Each V-type spring 2, off working state, tongue piece 1 exist there are one installations between tongue piece 1 and driven wheel 3
It is under the action of V-type spring 2 and struts upward extreme position.Driving wheel 4 is equipped with driven wheel close to the end face of driven axle
End cap 5 is limited, end cap 5 is fixed on driving wheel 4 by three screws, prevents from moving to axial between driven wheel 3 and driving wheel 4.
The application method of mono-directional overrun clutch in the embodiment：
When one, rotating：Driving wheel 4 is rotated counterclockwise by the drive of driving shaft, and the internal tooth of driving wheel 4 pushes tongue piece 1, band
Dynamic driven wheel 3 rotates together in the same direction.
When two, surmounting：Driving wheel 4 is rotated clockwise by the drive of driving shaft, and the internal tooth compressing tongue piece 1 of driving wheel overcomes
The elastic force of V-type spring 2 inwardly rotates, and crossing the realization of remaining in operation of tongue piece 1 until driving wheel 4 surmounts；Driven wheel 3 is not affected by this time
Rotating force remains static always.
The present invention uses tongue piece and V-type spring and various forms of by a kind of novel overrun clutch structure
Driving wheel and driven wheel etc., simple and convenient realizing surmount, and can be transmitted in running at high speed for a long time compared with big load, are promoted
The bearing capacity of freewheel clutch.
Obviously, the above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be pair
The restriction of embodiments of the present invention may be used also on the basis of the above description for those of ordinary skill in the art
To make other variations or changes in different ways, all embodiments can not be exhaustive here, it is every to belong to this hair
Row of the obvious changes or variations that bright technical solution is extended out still in protection scope of the present invention.
