Abstract
The utility model discloses a unidirectional self-power-increasing centrifugal clutch, consisting of centrifugal blocks, friction plates, springs, a driving shell and a driven shell. The unidirectional self-power-increasing centrifugal clutch is characterized in that convex blocks are uniformly arranged on the outer circumference of the driving shell at intervals, a knuckle pit is arranged on each convex block, a knuckle head arranged at one end of each centrifugal block is movably mounted in the knuckle pit, and two ends of each spring are respectively fixed on the corresponding centrifugal block and the corresponding convex block. The unidirectional self-power-increasing centrifugal clutch has the characteristics that the connection is stable, the sliding situation cannot be caused easily, the abrasion is very small, and the service life is longer.
Description
Technical field
The invention belongs to the Clutch Technology field, especially relate to a kind of unidirectional self-boosting type centrifugal clutch.
Background technique
Existing centrifugal clutch is to adopt two centrifugal-blocks to connect by spring, the inside and outside both sides of two centrifugal-blocks are respectively equipped with initiatively shell and passive shell, working principle is that initiatively hub rotates, the rotation of drive centrifugal-block, when rotating speed is lower than critical speed of rotation, centrifugal-block relies on initiatively hub under spring tension, disengage with passive hub, can not transferring power, when the rotating speed rising, when reaching a fixed angular speed, centrifugal-block is under the centrifugal acceleration effect, overcome tension spring tension, move radially along clutch, until the friction plate on the centrifugal-block is pressed on the passive hub inwall, with the power of driving shaft, reach passive hub, the torque of existing mechanism transferring power has substantial connection with the contact of friction material and passive hub, and there is following point in existing structure: 1, when one timing of driving shaft rotating speed, contact is a definite value, when loading moment surpassed contact, friction plate and passive hub skidded Fast Wearing; 2, when one timing of driving shaft rotating speed, the friction material wearing and tearing are equivalent to spring tension and strengthen, and enlarged portion is offset the centrifugal force of equivalent, and contact is reduced, and friction plate and passive hub skid Fast Wearing.
Summary of the invention
The object of the invention is to improve the deficiency of prior art and a kind of smooth engagement is provided, unidirectional self-boosting type centrifugal clutch minimum, longer service life is difficult for skidding, wearing and tearing.
The object of the present invention is achieved like this, a kind of unidirectional self-boosting type centrifugal clutch, formed by centrifugal-block, friction plate, spring, active shell and passive shell, be characterized in that the interval evenly is provided with projection on the excircle of shell initiatively, each projection is provided with fossa glenoid, the ball and socket joint that one end of centrifugal-block is provided with is movably arranged in the fossa glenoid, and the two ends of spring are separately fixed on centrifugal-block and the projection.
In order further to realize the purpose of this utility model, can be that the spring that is fixed on centrifugal-block and the projection is two.
Compared with the prior art the present invention has following distinguishing feature and good effect: the present invention adopts that the interval evenly is provided with three projections on the excircle of shell initiatively, each projection is provided with fossa glenoid, the ball and socket joint that one end of centrifugal-block is provided with is movably arranged in the fossa glenoid, the two ends of spring are separately fixed on centrifugal-block and the projection, pto＝power take-off drives when initiatively hub rotates, the rotation of drive centrifugal-block, rotating speed is lower than during the critical speed of rotation, and centrifugal-block relies on initiatively hub under spring force, disengage with passive hub, can not transferring power, when rotating speed raises, when reaching a fixed angular speed, centrifugal-block is under the centrifugal acceleration effect, overcome stage clip elastic force, rotate along rotary joint, until the friction plate on the centrifugal-block is pressed on the passive hub inwall, with the power of active shell, reach passive hub; Centrifugal-block is under the effect of centrifugal force, when moving to center of circle opposite direction, also can occur take rotary joint as the axle center, the motion opposite with the driving shaft sense of rotation, when centrifugal-block moves after being dragged by load, also occur to the motion of enlarged-diameter direction, the friction pressure of friction plate and passive hub can and increase along with the loading moment increasing, and the friction pressure value added of friction plate and passive hub is the several times of load torque value added, thereby eliminates skidding; The spring that is fixed on centrifugal-block and the projection is two, can guarantee that centrifugal-block is subjected to the stepless action of spring force, guarantees working stability.
Move with radial motion after such as Fig. 2 centrifugal-block being dragged and analyze:
Suppose to move apart from being behind the centrifugal-block: 12.5mm, and to the move distance of enlarged-diameter direction be: 87.5mm-82.5mm=5mm, 12.5/5=2.5, move distance behind the centrifugal-block and be 2.5 times of the radial displacement distance, so the friction pressure value added of friction plate and passive hub is 2.5 times of the load torque value added, thereby eliminate skidding.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 moves after centrifugal-block of the present utility model is dragged with radial motion to analyze schematic representation.
Embodiment
Embodiment 1, a kind of unidirectional self-boosting type centrifugal clutch, with reference to Fig. 1, that the interval evenly is provided with projection 6 on the excircle of initiatively shell 4, each projection 6 is provided with fossa glenoid 7, the ball and socket joint 8 that one end of centrifugal-block 1 is provided with is movably arranged in the fossa glenoid 7, the two ends of spring 3 are separately fixed on centrifugal-block 1 and the projection 6, and the outside of centrifugal-block 1 is fixed with friction plate 2, and passive shell 5 is enclosed in outside the centrifugal-block 1, when static, spring 3 is in compressive state, and 5 of centrifugal-block 1 and passive shells form the gap, and the quantity of projection 6 can arrange as required, present embodiment adopts three projections 6, and this consists of a kind of structure of the present utility model.
Embodiment 2, and a kind of unidirectional self-boosting type centrifugal clutch with reference to Fig. 1, is on embodiment 1 basis, are fixed on spring 3 on centrifugal-block 1 and the projection 6 and are two and are arranged side by side, and other and embodiment 1 are identical.
