Abstract
The utility model provides a quick overload protection type fluid coupling ware comprises fluid coupling part and quick overload protection part. Quick overload protection part is mainly by shaft coupling halfbody, steel ball, pressure disk, dish -shaped pressure spring, nut constitution. The shaft coupling halfbody passes through spline coupling with the pressure disk, does not influence pressure disk endwise slip on fluid coupling ware output shaft, installs, dismantles simple and conveniently simultaneously. The round ball socket has all been processed with the pressure disk to fluid coupling ware output shaft end face, and during normal operating, the steel ball inlays in fluid coupling ware output shaft end face and pressure disk ball socket, compresses tightly through dish -shaped pressure spring. During the overload, the instantaneous roll -off ball socket of steel ball cuts off moment of torsion transmission way, realizes overload protection. Eliminate the overload back, prize the pressure disk through external force and make dish -shaped pressure spring reset, resume moment of torsion transmission function. This kind of quick overload protection type fluid coupling ware can realize the soft start function and quick overload protection function of traditional hydraulic coupler simultaneously.
Description
Technical field
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; be grouped into by coupling fluid-structure part and quick overload protection portion; quick overload protection part is primarily of coupling halfbody; steel ball; platen; dish 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.Coupling halfbody is provided with several reset holes.
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 explanation
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.Coupling halfbody 3 is provided with several reset holes, after eliminating overload, use instrument prizes platen 5 by reset hole and makes the pressure of dish-shaped stage clip 6 reset recovery 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 (2)
1. a quick overload protection type hydraulic couplers; it is characterized in that: be grouped into by coupling fluid-structure part and quick overload protection portion; quick overload protection part is primarily of coupling halfbody; steel ball, platen, dish-shaped stage clip; nut forms; platen can slide on hydraulic couplers output shaft, and 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.
2. a kind of quick overload protection type hydraulic couplers according to claim 1, is characterized in that: coupling halfbody is provided with several reset holes.
