Detailed Description

Example 1

As shown in fig. 1 to 7, the utility model discloses a sprocket formula torsion overload protector, the main part comprises a plurality of lamellar structure, and wherein sprocket 3 provides torsion as the action wheel, can drive corresponding driven part and rotate, receives to obstruct when difficult the rotation at driven part, and sprocket 3 will increase torsion, and then makes driven part can continue to rotate, nevertheless damages too greatly in order to prevent the torsion that driven part received, the utility model discloses a main point of well design is, in case torsion exceeds the predetermined value, sprocket 3 will continue to rotate, but rotates the in-process driven part and no longer rotates.

In order to realize the above functions, in this embodiment, a second through hole 4, a slot 5, a through groove 7, a second wave plate 8, a third through hole 9, a ball 12, and a spring 13 are provided, wherein the second through hole 4 is provided in the middle of the sprocket 3, and the second wave plate 8 is located in the second through hole 4 and slidably connected to the sprocket 3, so that the sprocket 3 and the second wave plate 8 can rotate with each other, the second wave plate 8 is provided with a plurality of third through holes 9 capable of being fixed to other objects, such as a flange, and then the flange is fixed on a shaft, so that the second wave plate 8 can rotate with the shaft at the same time, in addition, the second through hole is further provided with a plurality of slots 5, the second wave plate 8 is provided with a plurality of through grooves 7 corresponding to the slots 5, when the installation and use, the ball 12 and the spring 13 need to be placed in the through groove 7, the ball 12 is tightly pressed into the slots 5 under the action of the spring 13, at this time, the balls 12 are partially in the slots 5 and partially in the through slots 7, when the torque is relatively small, the sprocket 3 provides torque to rotate, at this time, the balls 12 are driven by the slots 5 to rotate, and then the side faces of the balls push against the through slots 7 and drive the second wave plate 8 to rotate, the second wave plate 8 drives the flange plate to rotate, and finally drives the corresponding shaft to rotate, and if the shaft is blocked by too much force or is fixed, the sprocket 3 continues to increase the torque, and will not drive the shaft to continue to rotate, at this time, once the torque provided by the sprocket 3 exceeds a predetermined value, the slots 5 will continue to rotate, and the balls 12 pushed by the springs 13 will move inwards in an extruding manner, at this time, the balls 12 slide around the second through holes 4 until entering into another adjacent slot 5, and if an object connected with the second wave plate 8 still cannot rotate, the above process will be repeated, the magnitude of the preset torsion force can be controlled by controlling the number of the matched balls 12 and springs 13.

In order to prevent the sprocket 3, the second wave plate 8 drops at the pivoted in-process, or the ball 12, the spring 13 breaks away from the through-groove 7, set up end cover 1 in this embodiment, first through-hole 2, the third wave plate 10, fourth through-hole 11, wherein end cover 1 and third wave plate 10 are all set up for sprocket 3 upper and lower symmetry, all be equipped with the corresponding first through-hole 2 in a plurality of positions on end cover 1, the second wave plate 8, third wave plate 10, can couple together the device wholly through adapting unit such as first through-hole 2 cooperation bolts, and then spacing second through-hole 4 in sprocket 3 with second wave plate 8, the setting of fourth through-hole 11 can prevent ball 12, the upper and lower both sides of spring 13 from receiving the friction.

Sprocket 3 and second wave plate 8 are mutual rotation each other, in order to avoid end cover 1, second wave plate 8, third wave plate 10 to press from both sides tight sprocket 3 after connecting, still set up first wave plate 6 in this embodiment, can cooperate second wave plate 8 to install in the second through-hole 4 on sprocket 3 for space adaptation between two third wave plates 10 is in sprocket 3, can not press from both sides tight sprocket 3 and lead to it can't rotate for second wave plate 8.

As an optimized technical solution of the present invention, the thickness of the end cover 1 and the third wave plate 10 is 2mm.

As a preferred technical solution of the present invention, the end cap 1, the first wave plate 6, the second wave plate 8, on the third wave plate 10, the number of the first through holes 2 is 12.
