For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Need to prove, the word that uses in describing below " on " with orientation such as D score refer in the accompanying drawing upper and lower to, word " interior " and " outward " refer to respectively towards or specific features geometrical center direction away from drawing or in scheming.
Shown in Fig. 1-13, a kind of quick degree of tightness coupling system, it comprises: two fastenings are first, second reversal connection flange 1 of one; 2, two flanges have an opening end and a closed end, and first, second reversal connection flange is in the bottom and the top of quick degree of tightness coupling system respectively; The free end of two flanges is provided with annular bolts assemblies hole (free end is the closed end of flange); Two flange inner annular are provided with assembly cavity 10,20 (referring to Fig. 5 a, Fig. 6, Fig. 7, Fig. 6 is for analysing and observe the back sectional view for the first reversal connection flange that the direction dextrorotation turn 90 degrees along Fig. 5), and two assembly cavities constitute the holding cavity of slide block and locating stud jointly; Said assembly cavity has the inner fovea part 101,201 of band gradient; Wherein inner fovea part 101 is arranged to the sloping shape with gradient near the second reversal connection flange, one side, and its gradient is 14 °, and inner fovea part 201 is arranged to the sloping shape with gradient near the first reversal connection flange, one side; Its gradient is 14 °; The buckling end of two flanges is provided with awl tooth 11,21, the second reversal connection flanges middle part and is provided with axial through hole A22, and the first reversal connection flange is provided with radial direction through hole B12a, the 12b of symmetry.
Two are located at the slide block 3 of assembly cavity relatively; The upper and lower end parts of two slide blocks is provided with the bump 31,32 that cooperates and be with gradient with the assembly cavity inner fovea part; Bump 31 is arranged to the sloping shape with gradient towards bump 32 1 sides, and its gradient is 14 °, and bump 32 is arranged to the sloping shape with gradient towards bump 31 1 sides; Its gradient is 14 °, and two slide blocks are provided with tapped screw hole 33.
Be installed in the locating stud 4 of two flange assembly cavities; It comprises that two are located at boss 41,42 and the head 43 of band tapering at the bottom of the first reversal connection flange assembly cavity; The head of band tapering is located among the through hole A of the second reversal connection flange; This locating stud installing gets into after the assembly cavity of two flanges, and the bearing of trend of its two boss is vertical each other with the bearing of trend of slide block two screw holes, and locating stud is between two slide blocks.
Two be arranged in the slide block screw hole screw mandrel 5,5 ', slide block under the drive of screw mandrel can towards or away from the assembly cavity motion, the front end of screw mandrel is positioned at the space between the locating stud boss, the sheathed oil sealing in screw mandrel rear end and be arranged in through hole B 7.
Two fasten to first, second reversal connection flange buckling end of one circumferentially is provided with step-like groove, this groove installing protecting jacket 6, and this protecting jacket is provided with the through hole of symmetry, and protecting jacket is ringwise.
The bolts assemblies hole that the free end of two flanges is provided with is provided with each eight with the annular array mode, each bolts assemblies hole installing stud bolt 8.
Referring to Fig. 2 and Fig. 3, the said first and/or second reversal connection flange free end is provided with groove radially, is positioned at the side of setting, groove place bolt bar 9, said groove and put between the bolt bar and be provided with screw hole, and the two passes through screw.
Referring to Fig. 3, be provided with screw hole between the boss of said locating stud and the first reversal connection flange assembly cavity bottom, the two passes through screw.
When this quick degree of tightness coupling system is installed on the cardan shaft; If the dismounting cardan shaft only needs to use interior Hexagonal jacket, rotate the screw mandrel 5 of the band outer-hexagonal head of this quick degree of tightness coupling system to clockwise direction; Screw mandrel will drive slide block 3; Slide block 3 is moved inward, unclamp two reversal connection flanges, reach two reversal connection flanges and slide block and break away from.After slide block and two reversal connection flanges break away from, two reversal connection flanges vertically just do not have an active force, two reversal connection flanges just can come off automatically, are connected the cardan shaft of two reversal connection flange both sides and the transfer case of power intake and also just come off automatically.So just realized the effect of fast quick-detach cardan shaft.
After device maintenance was good, cardan shaft will install, and is also very convenient, only need be to the counter clockwise direction rotary screw rod, and screw mandrel drives slide block, outwards moves, and slide block band gradient part will slowly tighten two reversal connection flanges.Thereby realization quick mounting.In design, the flute profile of an end of two reversal connection flanges all is to be with tapering; K position shown in Fig. 5 a, flute profile all are the band taperings, when not having this quick degree of tightness coupling; The installation of cardan shaft is difficulty very, because at the end face of flange of transmission shaft, the fit tolerance of step during with the installation of another one flange has only within the 0.04mm; Has only the quite difficulty that cooperates of boss with the recess of 0.04mm so realize fit tolerance; And load onto after this quick degree of tightness coupling system, when two reversal connection flanges soon near the time, two reversal connection flanges need be on same straight line; As long as, differing several millimeters at the recessed position of another one reversal connection flange tooth, the tooth of a reversal connection flange can both realize quick mounting.A locating stud 4 also has been installed on reversal connection flange 1 in addition; This locating stud is installed in the neutral position of reversal connection flange through boss; The head of locating stud also is the band tapering; Size is identical with the clear size of opening of the reversal connection flange of an other end in the locating stud neutral position, and the gap has only 0.5-0.6mm between locating stud and the through hole.Also can realize quick location through locating stud through the through hole of another one reversal connection flange like this.
The above is merely the preferred implementation of the utility model, and the protection domain of the utility model is not limited in above-mentioned mode of execution, and every technological scheme that belongs to the utility model principle all belongs to the protection domain of the utility model.For a person skilled in the art, some improvement of under the prerequisite of the principle that does not break away from the utility model, carrying out, these improve the protection domain that also should be regarded as the utility model.
