Description
Technical field magnetic bullet shaft coupling relates to a kind of transmission coupling.
The current shaft coupling of background technology mostly uses frame for movement, and structure is complex.
nullThe purpose of summary of the invention magnetic bullet of the present invention shaft coupling is to propose a kind of simple in construction、Use the shaft coupling with overload protection of magnetic force，It is by left axle sleeve、Left button groove、Left disk、Outer housing、Through hole、Pellet、Permanent magnet、Cover plate、Endoporus、Cover plate bolt、Spring、Inner sleeve、Right disk、Right axle sleeve、Right button groove、Side plate，Side plate bolt composition，It is characterized in that: on the left of left disk, set left axle sleeve，Left button groove it is provided with in left axle sleeve，In left disk right periphery, outer housing is set，Outer housing is tubular，It is covered with through hole outside，It is provided with right axle sleeve on the right side of right disk，Right button groove it is provided with in right axle sleeve，On the left of right disk, periphery is provided with inner sleeve，Interior set is provided with endoporus，Inside it is set in outer housing，And the through hole on outer housing aligns with endoporus，Spring is set in endoporus，Pellet is set in through hole，Permanent magnet is set on through hole，Cover plate covers on through hole，Cover plate cover plate bolt is fixed，Pellet is adsorbed by permanent magnet，Side plate it is provided with on the right side of outer housing，Side plate is fixed on the right side of outer housing by side plate bolt.
Through hole, endoporus or be circular or for rectangle, pellet or be the assembly of cylinder and round platform, or be that rectangle adds trapezoidal cylinder for transverse section.
In actual use, left axle sleeve is connected with drive shaft, and right axle sleeve is connected with bearing axle, and pellet is adsorbed by permanent magnet, and pellet limits the relative motion between outer housing and inner sleeve, and such driving side is integrally forming with load-side.Magnet magnetic force is the biggest, and pellet cone angle is the least, and driving torque is the biggest.
When moment of torsion exceedes limit value, through-hole wall promotes pellet, pellet to depart from permanent magnet, and pellet is got into endoporus, and now outer housing departs from inner sleeve, and driving side disengages with load-side, it is achieved that safe overload is protected.
Outer housing and interior inner room have between gap, pellet and through hole and have gap, make the connection of load-side and driving side for flexibly connecting.
Compared with traditional shaft coupling, magnetic bullet shaft coupling has simple in construction, and overload protection speed is fast, overload get rid of after the feature such as system recovery automatically.
The features such as to have magnet consumption few for pellet magnetic shaft coupling of the present invention compared with traditional magnetic shaft coupling, and moment is big, overload protection speed is fast.
