Description
Technical field
The utility model belongs to the retainer and star-wheel of freewheel clutch technical field more particularly to a kind of freewheel clutch
Mounting structure.
Background technology
It is well known that double rolling key clutch refers to, one end axis hole connects driving shaft, and other end axis hole connects driven shaft, when
Outer shroud is motionless, and when driving shaft rotates clockwise or counterclockwise, driven shaft also rotates synchronously, and when driven shaft is acted on by moment of face
When, it cannot all rotate clockwise and anticlockwise.Current double rolling key clutch is usually band pusher dog structure, i.e. driving shaft rotates
When, it is necessary to pusher dog action is controlled, then just can guarantee that driven shaft is rotated together with driving shaft, therefore also known as controllable bidirectional is super
More clutch, such clutch need proprietary door to arrange pusher dog structure, and structure is comparatively laborious, need artificial or control system behaviour
Work could realize bidirectional overtaking function.
Utility model content
In order to solve the problems in the existing technology, the purpose of this utility model is to propose a kind of guarantor of freewheel clutch
Hold the mounting structure of frame and star-wheel.
In order to realize that above-mentioned the utility model aim, the utility model use technical solution as described below：
A kind of mounting structure of the retainer and star-wheel of freewheel clutch, including retainer ontology and star-wheel；
Retainer ontology comprising two and half retainers and a spring, two and half retainers be in semi-circular, two and half
The upper end of retainer is connected by spring, and the lower end of two and half retainers is connected on star-wheel, the circumference of two and half retainers
Several roller fixing grooves for installing roller are offered on face respectively；
Star-wheel is evenly distributed on external peripheral surface to offer and several be installed correspondingly with the roller fixing groove
The depth of rebate of slot, mounting groove is gradually reduced along clockwise direction, is provided with limiting slot on the external peripheral surface of star-wheel, two
The lower end of half retainer is connected in the left and right sidewall of limiting slot.
Further, the lower end of two and half retainers is both provided with hook, and the hook on two and half retainers corresponds to respectively
It is articulated in the left and right sidewall of limiting slot, and the mouth of hook of the hook on one and half retainers is towards a left side, on another half retainer
Hook the mouth of hook towards the right side.
Further, the hook is arranged in the inner circumference side of half retainer lower end.
Further, hook and half retainer of respective side are integrated machine-shaping.
Further, spring hanging hole, two and half retainer phases are both provided on the front/rear end of two and half retainer upper ends
It is connected by spring between the spring hanging hole of respective side.
Due to the adoption of the above technical scheme, the utility model has following superiority：
The utility model is novel, reasonable design, by the way that traditional Integral retainer is set as two and half retainers
Two halves structure, and connected by spring between two and half retainers, when in use, which can be higher turn in star-wheel
When fast, realize self-locking using centrifugal force or surmount, the service life of clutch can be greatly improved.

Specific implementation mode
The technical solution of the utility model is described in further detail with reference to the accompanying drawings and embodiments.
As shown in Figure 1, 2, 3, the mounting structure of a kind of retainer of freewheel clutch and star-wheel, including retainer ontology and
Star-wheel 3, retainer ontology include two and half retainers 1 and a spring 2, and two and half retainers 1 are in semi-circular, and two and half protect
The upper end for holding frame 1 is connected by spring 2, and the lower end of two and half retainers 1 is connected on star-wheel 3, the circumference of two and half retainers 1
Several roller fixing grooves 11 for installing roller are offered on side respectively；It is evenly distributed out on 3 external peripheral surface of star-wheel
Equipped with several with 11 one-to-one mounting groove 31 of the roller fixing groove, the depth of rebate of mounting groove 31 along clockwise direction by
It is decrescence small, limiting slot is provided on the external peripheral surface of star-wheel 3, the lower end of two and half retainers 1 is connected to limiting slot
Left and right sidewall on.
The lower end of two and half retainers 1 is both provided with hook 12, the corresponding mounting respectively of the hook 12 on two and half retainers
In the left and right sidewall of limiting slot, and the mouth of hook of the hook 12 on one and half retainers 1 is towards a left side, on another half retainer 1
Hook 12 the mouth of hook towards the right side.
The hook 12 is arranged in the inner circumference side of half retainer, 1 lower end.
Hook 12 and half retainer 1 of respective side are integrated machine-shaping.
Spring hanging hole 13, two and half retainers, 1 corresponding side are both provided on the front/rear end of two and half retainers, 1 upper end
Spring hanging hole 13 between connected by spring 2.
The operation principle of the utility model is：
When mounted, retainer ontology is mounted between star-wheel and outer shroud the utility model, and in roller fixing groove
Roller is installed, when star-wheel rotates and speed reaches a timing counterclockwise, left half retainer is counterclockwise under the influence of centrifugal force
Rotation pushes left side roller in roller gap deeply to shallow partial movement, when being moved to certain position, roller and star-wheel
And outer shroud self-locking, star-wheel drive outer shroud to rotate simultaneously, right half retainer is also by centrifugation force effect at this time, but due to half retainer of the right side
It can not rotate counterclockwise, therefore right half retainer is motionless, right side roller is located at deeper part in ball gap；When star-wheel up time
Needle rotates and speed reaches a timing, right half retainer rotation, right side roller and star-wheel and outer shroud self-locking, and left half retainer is not
It can rotate.
