Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of chain-type coupling system, including first Half a coupler 1,1 right end of the first half a coupler are equipped with drive sprocket 11, and the drive sprocket 11 is connected by double strand chain 5 Have driven sprocket 21, teeth be equipped on the drive sprocket 11 and driven sprocket 21, be cased in the teeth it is anti-raise one's hat, can be with Double strand chain 5 is prevented to be detached from from drive sprocket 11 and driven sprocket 21.The driven sprocket 21 is located at the second half a coupler 2 The inner wall of left end, second half a coupler 2 and the first half shaft couplings is provided with slot 3, and the quantity of the slot 3 is 6, described Terminal pad 4 is installed, 4 left and right ends of terminal pad are welded in the gap between first half a coupler 1 and the second half a coupler 2 It is connected to inserted block 41, and inserted block 41 is plugged in slot 3, as the first half a coupler 1 drives the second half shaft couplings by double strand chain 5 Device 2 is rotated, and when there is the case where double strand chain 5 snaps suddenly, the second half a coupler 2 will lose double strand chain 5 The speed of transmission, 2 speed of the second half a coupler and the first half a coupler 1 will be no longer identical, and at this moment, terminal pad 4 will pass through inserted block 41 are plugged in slot 3, are driven for the first half a coupler 1 and the second half a coupler 2, to ensure that the normal of shaft coupling Work.The outer end junction of first half a coupler 1 and the second half a coupler 2 is equipped with protective shell 6, and the protective shell 6 is SKH57 high-speed steel protective shell, 6 inner end of protective shell are fixedly connected with convex block 61, and 5 left and right ends end abutment of double strand chain There is convex block 61, can not only prevent dust from entering by protective shell 6, avoid dust from dropping on double strand chain 5, influence double strand chain The normal work of item 5, moreover, the convex block 61 on protective shell 6 can limit drive chain when double strand chain 5 loses transmission effect The position of wheel 11 and driven sprocket 21 prevents driving shaft and driven shaft to be detached from and have an accident.Include in the protective shell 6 The first half protective shells, the second half protective shell and fixing bolts, the first half protective shell are fixedly connected with second by fixing bolt Half protective shell.

Working principle: when there is the case where double strand chain 5 snaps suddenly, the second half a coupler 2 will lose double strand chain The speed of the transmission of item 5,2 speed of the second half a coupler and the first half a coupler 1 will be no longer identical, at this moment, terminal pad 4 will lead to It crosses convex block 61 to be plugged in slot 3, be driven for the first half a coupler 1 and the second half a coupler 2, to ensure that shaft coupling Normal work；When the second half a coupler 2 is during being rotated, meeting generate becoming for centrifugal movement because lacking constraint Gesture, but because the convex block 61 on protective shell 6 abuts the left and right ends of double strand chain 5, so that drive sprocket 11 and driven sprocket 21 Position be restricted, to prevent the disengaging of driving shaft and driven shaft, avoid the generation of peril.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
