Abstract
The invention discloses an overload preventing transmission device comprising a first transmission shaft, a cylindrical shell, strong permanent magnets, a hollow chamber, a circular baffle plate, rolling balls and a second transmission shaft. The first transmission shaft and the second transmission shaft are connected with the cylindrical shell through a bearing. One end of the first transmission shaft is provided with the hollow chamber. One strong permanent magnet is arranged in the hollow chamber. One end of the hollow chamber is sleeved by the circular baffle plate. One end of the circular baffle plate is provided with one circular baffle plate. The other end of the circular baffle plate is connected with one end of the second transmission shaft through the rolling balls. According to the overload preventing transmission device, the rolling balls are separated from grooves when rotating force from the second transmission shaft is greater than the effect of repulsive force between the strong permanent magnets through the effect of the repulsive force between the strong permanent magnets so that the second transmission shaft is enabled to stop rotating, and then the overload phenomenon of a motor can be prevented.
Description
Technical field
The present invention relates to transmission art field, a kind of anti-overload actuating device.
Background technology
At present, it is mostly bolt connection for connecting the attachment means of driving shaft and power transmission shaft, the so transmission speed of main shaft and transmission speed of countershaft is identical, but, the device being driven for needs connected due to countershaft, when the device that needs are driven is heavier, at this moment main shaft is accomplished by providing bigger transmission dynamics, when transmission dynamics now is more than the specified output of motor, it is likely that the phenomenon that motor burns out occurs.
Summary of the invention
It is an object of the invention to provide a kind of anti-overload actuating device, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme: a kind of anti-overload actuating device, including the first power transmission shaft, cylindrical outer casing, strong permanent magnets, hollow chamber, circular baffle plate, ball and second driving shaft, described first power transmission shaft and second driving shaft are connected with described cylindrical outer casing by bearing, one end of described first power transmission shaft is provided with described hollow chamber, the inside of described hollow chamber is provided with strong permanent magnets described in, one end set of described hollow chamber puts circular baffle plate described in, one end of described circular baffle plate is provided with strong permanent magnets described in, the other end of described circular baffle plate is connected by ball with one end of described second driving shaft.
Preferably, the magnetic of the opposite of strong permanent magnets described in two is identical.
Preferably, described circular baffle plate and described second driving shaft are provided with the semi-circular recesses for placing described ball at the position being connected with described ball.
Preferably, include eight groups for placing the semi-circular recesses of described ball, and be evenly distributed on 3/4 radius circle of described circular baffle plate and described second driving shaft.
Preferably, the other end of described first power transmission shaft and the other end of described second driving shaft are equipped with the bolt hole for connecting.
Compared with prior art, the invention has the beneficial effects as follows: a kind of anti-overload actuating device, by repulsion effect middle between strong permanent magnets, when being more than the effect of repulsion between strong permanent magnets from the rotation dynamics of second driving shaft, ball can depart from groove, second driving shaft is stopped the rotation, and then prevents the generation of motor overloading.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
In figure: 1, the first power transmission shaft, 2, cylindrical outer casing, 3, strong permanent magnets, 4, hollow chamber, 5, circular baffle plate, 6, ball, 7, second driving shaft.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Refer to Fig. 1, the present invention provides a kind of technical scheme: a kind of anti-overload actuating device, including the first power transmission shaft 1, cylindrical outer casing 2, strong permanent magnets 3, hollow chamber 4, circular baffle plate 5, ball 6 and second driving shaft 7, described first power transmission shaft 1 and second driving shaft 7 are connected with described cylindrical outer casing 2 by bearing, one end of described first power transmission shaft 1 is provided with described hollow chamber 4, the inside of described hollow chamber 4 is provided with strong permanent magnets 3 described in, one end set of described hollow chamber 4 puts circular baffle plate 5 described in, one end of described circular baffle plate 5 is provided with strong permanent magnets 3 described in, the other end of described circular baffle plate 5 is connected by ball 6 with one end of described second driving shaft 7.
Described in two, the magnetic of the opposite of strong permanent magnets 3 is identical；Described circular baffle plate 5 and described second driving shaft 7 are provided with the semi-circular recesses for placing described ball 6 at the position being connected with described ball 6；Include eight groups for placing the semi-circular recesses of described ball, and be evenly distributed on 3/4 radius circle of described circular baffle plate 5 and described second driving shaft 7；The described other end of the first power transmission shaft 1 and the other end of described second driving shaft 7 are equipped with the bolt hole for connecting.
Specifically used mode: in present invention work, by repulsion effect middle between strong permanent magnets 3, when being more than the effect of 3 repulsion of strong permanent magnets from the rotation dynamics of second driving shaft 7, ball 6 can depart from groove, second driving shaft 7 is stopped the rotation, and then prevents the generation of motor overloading.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, and without departing from the spirit or essential characteristics of the present invention, it is possible to realize the present invention in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in the present invention.Should not be considered as limiting involved claim by any reference in claim.
