Description
Technical field
The utility model relates to a kind of coupling, relates in particular to a kind of coupling with overload protection.
Background technique
Current continuous rolling production line.The transmission of power of motor is given a concentrated transmission case or is power distribution case, has many output shafts, and every output shaft is given corresponding frame by coupling by transmission of power.When certain frame breaks down, or other reason causes loading excessive, and the shear pin of coupling the inside is cut off, and this frame runs out of steam.In each frame, have windrow to shut down, due to spatial position and people, always action is sensitive not, so, often have two, three even five, six frames windrows in succession, cut off shear pin, deal with very loaded down with trivial details.
Separately having China Patent No. is 201120180591.7 to disclose the utility model of a kind of elastic coupler of safety pin, its structure characteristic is that pin passes in the sliding bearing in the elastic sleeve that half-coupling I boss embeds and half-coupling II is fixed, pin is rotary with nut, with nut, half-coupling I and half-coupling II is tightened; Half-coupling I is connected with drive motor, and half-coupling IIYu working end machinery connects, and by the fixing half-coupling IIYu working end machinery of safety pin.The utility model links together drive motor and working end by safety pin; when the load of working end surpasses the setting value of safety pin; safety pin is sheared and is disconnected because of overload; drive end and working end are thrown off; thereby protection drive motor and working end equipment (as retarder etc.); although having solved elastic coupling flexible coupling, this model utility cannot reach the problem that mechanical type torque overload is protected; but Power Drive Unit can not autostop or warning; even one or more frames are windrow in succession, has increased labor intensity.
Model utility content
In order to overcome the defect of above-mentioned prior art, the utility model provides a kind of coupling with overload protection, when overload appears in certain frame, and when safety pin is cut off, can autostop or warning, reduce fault, reduce labor intensity, enhance productivity.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
Coupling with overload protection, comprise connecting sleeve, internal gear, described connecting sleeve is connected by shear pin with internal gear, it is characterized in that: described internal gear vertically interval have three through holes, the right connecting sleeve of each through hole is provided with a pit, is placed with the steel ball that can move in described through hole in described pit;
Also comprise and connect electricity ring and push rod, Compress Spring is installed on push rod, described push rod one end is encircled and is connected with connecing electricity, and the other end passes into through hole and is pressed on steel ball;
Also comprise a trolley pole, when push rod is ejected by steel ball, described in connect electricity ring and be connected with trolley pole, described trolley pole is connected with warning device or arresting gear.
Described connecting sleeve is connected with the transmission shaft of drive unit, the external gear engagement of internal gear and working end equipment.
Described trolley pole fixed insulation puts, and insulating bush is fixed on fuselage.
The utlity model has following advantage:
1, in the utility model internal gear vertically interval have three through holes three through holes of decile (preferably), the right connecting sleeve of each through hole is provided with a pit,, in described pit, be placed with the steel ball that can move in described through hole; Also comprise and connect electricity ring and push rod, described push rod one end is encircled and is connected with connecing electricity, and the other end passes into through hole and is pressed on steel ball; Also comprise a trolley pole, when push rod is ejected by steel ball, described in connect electricity ring and be connected with trolley pole; described trolley pole is connected with warning device or arresting gear; when transship working end, shear pin is cut off, only transmission shaft and connecting sleeve rotation; now steel ball is connected cover and ejects pit; connect electricity ring and connect with trolley pole, thereby realize autostop or warning, reduce frame windrow degree; reduce labor intensity, enhance productivity.
2, in the utility model, connecting sleeve is connected with the transmission shaft of drive motor; the external gear engagement of internal gear and working end equipment; shear pin is cut off; only transmission shaft and connecting sleeve rotation; now slider will deviate from pit be connected cover eject; connect electricity ring and connect with trolley pole, thereby more easily realize autostop.
3, in the utility model, trolley pole fixed insulation puts, and insulating bush is fixed on fuselage, thereby makes this coupling electric property stable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, mark 1 is transmission shaft, and 2 is connecting sleeve, and 3 is shear pin, and 4 is external gear, and 5 for connecing electricity ring, and 6 is internal gear, and 7 is slider, and 7.1 is push rod, 7.2 steel balls, and 8 is trolley pole, and 9 is insulating bush, and 10 is wire, and 11 is pit, 12 is through hole.
Embodiment
As shown in Figure 1, coupling with overload protection, comprise connecting sleeve 2 and internal gear 6, connecting sleeve 2 is rigidly connected with the transmission shaft 1 of drive unit (concentrated transmission case), connecting sleeve 2 is connected by shear pin 3 with internal gear 6, internal gear 6 vertically interval have three best deciles of through hole 12(), on the connecting sleeve 2 that is positioned at through hole 12 places, being provided with pit 11(is on the right connecting sleeve of each through hole, to be provided with a pit), 11 li of described pits are placed with the steel ball 7.2 that can move in described through hole;
Also comprise and connect electricity ring 5 and push rod 7.1, Compress Spring is installed on push rod, described push rod 7.1 one end with connect electricity encircle 5 be connected after, the other end packs the through hole 12 of internal gear 6 into, push rod 7.1 is pressed in steel ball 7.2 in the pit of connecting sleeve 2;
