Abstract
The utility model relates to a castellated electromagnetic clutch, which is characterized in that an excitation coil is arranged at the front end of a magnetic yoke; a ring-shaped baffle with a shaft is movably arranged on the front end of the magnetic yoke through a central hole of the magnetic yoke; the ring-shaped baffle has face teeth at the front end; a ring-shaped armature is arranged opposite the ring-shaped baffle; the ring-shaped armature has matching face teeth at the front, with a spline gear ring at the back; a ring-shaped coupling plate is arranged at the back end of the armature through bolts and compression springs; the outer ring of the ring-shaped coupling plate is provided with spline teeth that are matched with the armature gear ring; the front end of the ring-shaped baffle is provided with a plurality of blind threaded holes, in which a post-shaped jingse with shaft shoulder and a recovery spring are arranged; the threaded holes are provided with a ring-shaped locknut that restricts post-shaped jingse and the recovery spring. In case of power off, the armature is propped open timely by the post-shaped jingse, thereby improving reliability of the clutch; in addition, the utility model has the advantages of simple structure and easy manufacture.
Description
Technical field
The utility model relates to a kind of magnetic clutch that is used for machine driven system, especially a kind of slipping toothed electromagnetic clutch.
Background technique
Slipping toothed electromagnetic clutch is mainly used in the machine driven system, and it can be under master and slave moving axis relative rotation speed be zero situation, realizes the combination of driven and driving shaft or separates.Known slipping toothed electromagnetic clutch structure is: the yoke of annular has center hole and field coil, be movably arranged on the ring baffle of yoke front end by the yoke center hole, the front end of ring baffle is shaped on the end face tooth, the rear end of ring baffle is shaped on the axle with yoke center hole coupling, this axle is shaped on center hole and keyway, on the baffle plate opposite armature is installed, the front of armature is shaped on the end face tooth that is complementary with ring baffle end face tooth, the armature back side is shaped on spline gear, the armature ear end face is equipped with annular jointing plate by screw and pressure spring, and the outer ring of annular jointing plate is shaped on the spline tooth with armature gear ring coupling.The slipping toothed electromagnetic clutch of this structure is suitable for horizontal arrangement.When vertical use, because the deadweight of armature, make armature return fully sometimes during outage, cause this clutch not separate, cause the machine driven system transmission malfunctioning.
Summary of the invention
The utility model can vertically use for the technical problem that exists in the solution known technology provides a kind of, reliable slipping toothed electromagnetic clutch.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of slipping toothed electromagnetic clutch, comprise the annular yoke that has center hole and field coil, be movably arranged on the ring baffle that has the end face tooth of yoke front end by the yoke center hole, the front that is installed in the baffle plate opposite has the ring armature that coupling end face rear flank has spline gear, and have with the annular jointing plate of the spline tooth of armature gear ring coupling by the outer ring that screw and pressure spring are installed in the armature ear end face and to form, the front-end face of described baffle plate is shaped on several tapped blind holes, column holder and the Returnning spring that has the shaft shoulder is installed in each tapped blind hole, the ring-type locknut of restriction column holder and Returnning spring is installed on the tapped hole.
The utility model can also adopt following technological scheme:
Described tapped hole has three.
The back side of described ring-type locknut is shaped on counterbore.
Advantage and the good effect that the utlity model has are:
Because the front-end face at baffle plate is shaped on several tapped blind holes, by the ring-type locknut column holder and the Returnning spring that can push armature open is installed in each tapped blind hole, when outage, armature is pushed open in time by the column holder, improved the reliability of this clutch; In addition, the utility model also has advantage simple in structure, that be easy to make.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1, jointing plate; 2, armature; 3, ring baffle; 4, coil; 5, yoke; 6, bearing; 7, Returnning spring; 8, holder; 9, locknut; 10, screw; 11, pressure spring; 12, end face tooth; 13, end face tooth; 14, center hole; 15, keyway.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, the yoke 5 that has a center hole ringwise, its cross section is Y-shaped, the front end of yoke is equipped with field coil 4, by bearing 6 movable ring baffle 3 that has axle of installing in the yoke center hole, the axle center of ring baffle is shaped on center hole 14 and the keyway 15 thereof that is connected with driving component, and the front end of ring baffle is shaped on end face tooth 13.Corresponding installation is armature 2 in the ring baffle front, the front correspondence of armature is shaped on the end face tooth 12 of coupling, the back side of armature is shaped on spline gear, the back side of armature is equipped with the jointing plate 1 that is connected with driving component by screw 10 and pressure spring 11, jointing plate ringwise, the outer ring of jointing plate is shaped on the spline tooth with armature gear ring coupling.In order to improve the return elastic force of armature, front-end face at baffle plate is shaped on several tapped blind holes, present embodiment is 3, column holder 8 and the Returnning spring 7 that has the shaft shoulder is installed in each tapped blind hole, the ring-type locknut 9 of restriction column holder and Returnning spring is installed on the tapped hole, the back side of ring-type locknut is shaped on the counterbore with column holder shaft shoulder coupling, makes holder and spring more flexible, stable like this.
Claims (3)
1. slipping toothed electromagnetic clutch, comprise that the annular that has center hole and field coil bumps yoke, be movably arranged on the ring baffle that has the end face tooth of yoke front end by the yoke center hole, the front that is installed in the baffle plate opposite has the ring armature that coupling end face rear flank has spline gear, and have with the annular jointing plate of the spline tooth of armature gear ring coupling by the outer ring that screw and pressure spring are installed in the armature ear end face and to form, it is characterized in that: the front-end face of described baffle plate is shaped on several tapped blind holes, column holder and the Returnning spring that has the shaft shoulder is installed in each tapped blind hole, the ring-type locknut of restriction column holder and Returnning spring is installed on the tapped hole.
