Abstract
The utility model relates to an anti-collision embedded type overrunning clutch which comprises a ratchet wheel, pawls and a rotation disk. The ratchet wheel is sleeved on the outer side of the rotation disk, the pawls are arranged on the inner circumferential face of the ratchet wheel, first permanent magnets are embedded on the pawls, a groove is arranged on the outer circumferential face of the rotation disk, the pawls are evenly arranged in the groove at intervals, the pawls are movably connected with the rotation disk through pawl shafts, second permanent magnets are embedded at the ratchet ends of the pawls at the positions corresponding to the first permanent magnets, third permanent magnets are embedded at the corresponding position of the bottom of the groove and the tail portions of the pawls, and repulsive force between the first permanent magnets and the second permanent magnets is smaller than attraction force between the third magnets and the tail portions of the pawls. The anti-collision embedded type overrunning clutch has the advantages of being novel in design and reliable in structure, achieving soft landing between the pawls and the ratchets through repulsive force between permanent magnets, and preventing pawls from directly colliding the ratchets to deform or be broken under the action of centripetal force and magnetic force.
Description
Technical field
The utility model relates to a kind of free wheel device, especially relates to the embedded free wheel device of a kind of anticollision.
Background technique
Free wheel device is the basic part that occurs along with the development of electromechanical integrated product, and it is the vitals for transmission of power between prime mover and the working machine or between machine intimate driving shaft and the driven shaft and separation function.It is the conversion that utilizes velocity variations or the sense of rotation of driving and driven part, has the voluntarily device of clutch function.Be ZL01129231.8 in the patent No., patent name is in the patent of " a kind of free wheel device ", about magnet installation process mode be: stud with ratchet on the pawl disk, ratchet is supported on the pawl disk by pawl axis rotationally, the place is provided with permanent magnet at ratchet tail end axis, permanent magnet is embedded on the pawl disk, and this structure can guarantee ratchet reliably motion under the effect of magnetic force.Although the free wheel device of this structure can better guarantee the reliability of clutch short-term job, but the free wheel device of this structure is also Shortcomings part in use, for example: free wheel device is when starting, ratchet can strike on the ratchet under the effect of the centripetal force of moment and magnetic force, after how the number of times of bump becomes, distortion will appear in ratchet, even the situation that fracture occurs occurs, thereby affect the working life of ratchet, simultaneously also so that there is certain potential safety hazard in this free wheel device when long-term the use.
The model utility content
The purpose of this utility model provides the embedded free wheel device of a kind of anticollision, and it reaches the function that soft landing relies on by the repulsive force between the permanent magnet, has avoided excessive because of impact force or clashed into for a long time the situation that makes ratchet distortion or fracture occur occuring.
The purpose of this utility model is to be achieved through the following technical solutions:
The embedded free wheel device of a kind of anticollision, comprise ratchet, ratchet and rolling disc, described ratchet sleeve is located at the outside of rolling disc, the inner peripheral surface of ratchet is provided with ratchet, be inlaid with permanent magnet one on the ratchet, offer groove on the outer peripheral surface of described rolling disc, evenly be interval with ratchet in the groove, ratchet is flexibly connected by pawl axis and rolling disc, and the ratchet end of ratchet and permanent magnet one corresponding position is inlaid with permanent magnet two, and the position corresponding with the afterbody of ratchet, the bottom of described groove is inlaid with permanent magnet three.The repulsive force that forms between described permanent magnet one and the permanent magnet two is less than the attraction force that forms between permanent magnet three and the ratchet afterbody.
The beneficial effects of the utility model are: modern design, reliable in structure, long service life, by the repulsive force between the permanent magnet, so that pull off a soft landing between ratchet and the ratchet, thereby avoided ratchet direct phenomenon generation of clashing into ratchet and occurring being out of shape or rupturing under the effect of centripetal force and magnetic force.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the broken section structural representation of the embedded free wheel device of the described anticollision of the utility model embodiment;
Fig. 2 is the sectional view of the described rolling disc of the utility model embodiment.
Among the figure:
1, ratchet; 2, ratchet; 3, rolling disc; 4, ratchet; 5, permanent magnet one; 6, groove; 7, pawl axis; 8, permanent magnet two; 9, permanent magnet three.
Embodiment
Shown in Fig. 1-2, the embedded free wheel device of the described a kind of anticollision of the utility model embodiment, comprise ratchet 1, ratchet 2 and rolling disc 3, described ratchet 1 is set in the outside of rolling disc 3, the inner peripheral surface of ratchet 1 is provided with ratchet 4, be inlaid with permanent magnet 1 on the ratchet 4, offer groove 6 on the outer peripheral surface of described rolling disc 3, the groove 6 interior ratchets 2 that evenly are interval with, ratchet 2 is flexibly connected by pawl axis 7 and rolling disc 3, and the ratchet end of ratchet 2 and permanent magnet one 5 corresponding positions are inlaid with permanent magnet 28, and the position corresponding with the afterbody of ratchet 2, the bottom of described groove 6 is inlaid with permanent magnet 39.The attraction force that forms between the afterbody of repulsive force less than permanent magnet 39 and ratchet 2 that forms between described permanent magnet 1 and the permanent magnet 28.
During concrete the use, rolling disc 3 is connected with motor shaft, drives rolling disc 3 by motor shaft and rotate, drive ratchet 1 by rolling disc 3 again and rotate.In the process of rotating, be movably installed on the rolling disc 3 owing to ratchet 2, thereby so that ratchet 2 can outwards rotate under the effect of centripetal force, and because the position corresponding with the afterbody of ratchet 2, bottom of groove 6 is inlaid with permanent magnet 39, thereby so that ratchet 2 can be accelerated the outwards speed of rotation under the effect of permanent magnet 39 attraction forces, can cushion the speed that ratchet 2 outwards rotates this moment by being installed in the permanent magnet 1 on the ratchet 4 and being installed in the repulsive force that produces between the permanent magnet 28 on the ratchet 2, to reach the effect of soft landing, thereby avoided ratchet 2 direct phenomenon generation of clashing into ratchet 4 and distortion occurring or rupturing under the effect of centripetal force and magnetic force, increased greatly the working life of ratchet 2.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technological scheme, all drops within the protection domain of the present utility model.
