Abstract
The invention relates to a quick overload protection type hydraulic coupler. The quick overload protection type hydraulic coupler consists of a hydraulic coupling part and a quick overload protection part. The quick overload protection part mainly consists of a coupler half body, steel balls, a pressure disc, a disc pressure spring and a nut. The coupler half body and the pressure disc are in splined connection without influencing axial slide of the pressure disc on an output shaft of the hydraulic coupler; and the installation and the disassembly are simple and convenient. The end surface of the output shaft of the hydraulic coupler and the pressure disc are respectively provided with a lap of ball sockets. In normal operation, the steel balls are embedded in the ball sockets of the end surface of the output shaft of the hydraulic coupler and the pressure disc, and are tightly pressed through the disc pressure spring. In overloading, the steel balls instantly slide outside the ball sockets to cut off a torque transfer path so as to realize the overload protection. After the overload is eliminated, the pressure disc is pried by external force so as to return the disc pressure spring, so that a torque transfer function is restored. The quick overload protection type hydraulic coupler can synchronously realize a soft starting function and a quick overload protection function of a traditional hydraulic coupler.
Description
Art
The present invention relates to a kind of quick overload protection type hydraulic couplers, be mainly used in realizing conventional fluid torque Coupler soft start function, the function of quick overload protection can be realized again.
Background technique
Along with scientific development; technological progress; the overload protection problem of manufacturing machine more and more comes into one's own; people are also more and more higher to the sensitivity of overload protection arrangement, precise requirements; traditional hydraulic couplers adopts fusible plug hydrojet to realize overload protection, but this method overload protection is delayed, and needs to change fusible plug; lose time, affect manufacturing efficiency.
Summary of the invention
In order to realize the object of the overload protection of rapid sensitive, there is the soft start function of hydraulic couplers simultaneously, the invention provides a kind of brand-new quick overload protection type hydraulic couplers.
The present invention solves the scheme that its technical problem adopts: a kind of quick overload protection type hydraulic couplers, is grouped into by coupling fluid-structure part and quick overload protection portion.Quick overload protection part is primarily of coupling halfbody, and steel ball, platen, dish-shaped stage clip, nut forms.Coupling halfbody and platen are by splined, and platen can slide axially on hydraulic couplers output shaft.Hydraulic couplers output shaft end face and platen are all processed with a circle ball-and-socket, and when normally running, steel ball is embedded in the ball-and-socket of hydraulic couplers output shaft end face and platen, is compressed by dish-shaped stage clip.During overload, overload moment steel ball skids off ball-and-socket, cuts off moment of torsion transmission way, realizes overload protection.After eliminating overload, prize platen by external force and dish-shaped stage clip is resetted, recover moment of torsion propagation function.
The invention has the beneficial effects as follows: overload protection can not only be realized rapidly and accurately, and the function of soft start can be realized, simultaneously installation, convenient disassembly.
Accompanying drawing illustrates:
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is overall structure schematic diagram of the present invention.
Fig. 2 is overload protection phase diagram.
1. hydraulic couplerss in figure, 2. hydraulic couplers output shaft, 3. coupling halfbody, 4. steel ball, 5. platen, 6. dish-shaped stage clip, 7. nut, 8.O type circle.
Embodiment
In Fig. 1, Fig. 2, a kind of quick overload protection type hydraulic couplers is grouped into by coupling fluid-structure part and quick overload protection portion.Coupling fluid-structure part forms primarily of hydraulic couplers 1, and quick overload protection part is by coupling halfbody 3, and steel ball 4, platen 5, dish-shaped stage clip 6, nut 7, O type circle 8 forms.Coupling halfbody 3 and platen 5 are by splined, and platen 5 can slide axially on hydraulic couplers output shaft 2.Hydraulic couplers output shaft 2 end face and platen 5 are all processed with a circle ball-and-socket, and during normal operation, steel ball 4 is embedded in the ball-and-socket of hydraulic couplers output shaft 2 end face and platen 5, is compressed by dish-shaped stage clip 6.During overload; steel ball 4 overcomes the instantaneous ball-and-socket skidding off hydraulic couplers output shaft 2 end face of dish-shaped stage clip 6 applied pressure; now dish-shaped stage clip 6 stressed after can overturn due to stress relation; pressure can not be produced to platen 5; thorough cut-out torque transmission paths; without residual torque, realize momentary overload protection.After overload is eliminated, use instrument prizes platen 5 by reset hole makes dish-shaped stage clip 6 reset, and recovers the pressure to platen 5, makes steel ball 4 again be embedded between the ball-and-socket of hydraulic couplers output shaft 2 and platen 5, recovers moment of torsion propagation function.O type circle 8 plays seal action, stops dust to enter in ball-and-socket and produces wearing and tearing to steel ball 4.Because coupling halfbody 3 and platen 5 are by splined, to install, easy removal, save time, enhance productivity, and the dual functions that hydraulic couplers soft start and quick overload protect can be realized.
Claims (4)
1. a quick overload protection type hydraulic couplers, is characterized in that: be grouped into by coupling fluid-structure part and quick overload protection portion, and quick overload protection part is primarily of coupling halfbody, and steel ball, platen, dish-shaped stage clip, nut forms.Platen can slide on hydraulic couplers output shaft.Platen and hydraulic couplers output shaft end face are all processed with a circle ball-and-socket, and steel ball is pressed in the ball-and-socket of hydraulic couplers output shaft end face by dish-shaped stage clip and nut by platen.When overload occurs, steel ball overcomes the instantaneous ball-and-socket skidding off hydraulic couplers output shaft end face of dish-shaped stage clip applied pressure, and moment of torsion transmission way, by insantaneous break, realizes the object of overload protection.
2. a kind of quick overload protection type hydraulic couplers according to claim 1, is characterized in that: coupling halfbody and platen, by splined, neither affect platen sliding axially on hydraulic couplers output shaft, also make installation, easy removal.
3. a kind of quick overload protection type hydraulic couplers according to claim 1, is characterized in that: when overload occurs, can overturn after dish-shaped stage clip is stressed; no longer pressure is applied to platen; thorough cut-out moment of torsion transmission way, without residual torque, realizes overload protection.
4. a kind of quick overload protection type hydraulic couplers according to claim 1; it is characterized in that: coupling halfbody is provided with several reset holes; after overload is eliminated, use instrument prizes platen by reset hole makes dish-shaped stage clip reset, and recovers moment of torsion propagation function.
