It elaborates with reference to the accompanying drawing to specific embodiment of the utility model.
As shown in Figure 1, Figure 2 and Figure 3, the utility model is a kind of exclusive compound tight for graded crushing equipment shaft coupling
Firmware, wedge bolt 1 and two-sided wedge-shaped sleeve 2 including coaxial arrangement, two-sided wedge-shaped sleeve 2 are located at the outer ring of wedge bolt 1, wedge shape
Bolt 1 includes the nut 11 and solid lock screw rod 12 of connection, and solid lock screw rod 12 is from one end close to nut 11 to the other end at section
Diminishing wedge shape, the inner ring of two-sided wedge-shaped sleeve 2 and the outer ring clearance fit of solid lock screw rod 12, the outer ring of two-sided wedge-shaped sleeve 2
From one end close to nut 11 to the other end at the diminishing wedge shape of section, transition is equipped between nut 11 and solid lock screw rod 12
Chamfering 13, solid lock screw rod 12 sequentially pass through active connector 3 and are cooperated after follower link 4 with stop nut 6, stop nut 6
Tightening direction and shaft coupling direction of rotation on the contrary, stop nut 6 and by between follower link 4 be equipped with ripple pad 5, nut 11
Section close to 12 side of solid lock screw rod contacts setting with active connector 3, and under normal condition, two-sided wedge-shaped sleeve 2 is far from nut
Minimum range of 11 one end apart from ripple pad 5 is 1~5mm, preferably 2mm or 3mm, reserves falling off for two-sided wedge-shaped sleeve 2
Space timely feedbacks the failure state of cooperation, plays the role of equipment and shuts down, protects other parts, is tying apart from excessive
It is easy to fall off in structure operation process, assembly maintenance period shortens, and cannot achieve the requirement that falls off in time apart from too small, it is preferable that wave
Line pad 5 uses in pairs, and stopping effect is good.
Preferably, transition chamfering 13 is 45 degree of chamferings, and the side length of transition chamfering 13 is the 1/4 of 12 diameter of solid lock screw rod, mistake
The diameter of the specification and solid lock bolt of crossing chamfering 13 sets suitable ratio, and intensity is high, and stability is good；It is highly preferred that nut 11
One end far from solid lock screw rod 12 is equipped with the location hole 14 of indent, and location hole 14 is positive polygonized structure.
Preferably, the gradient of solid lock screw rod 12 is 1:25, the gradient of two-sided 2 inner ring of wedge-shaped sleeve is 1:25, bevel friction power
It is moderate, meet the needs of coupling torque transmitting, stability is good；It is highly preferred that the gradient of two-sided 2 outer ring of wedge-shaped sleeve is 1:20,
Setting is matched with the original bolt hole faying face of shaft coupling, this gradient is less than the gradient of solid lock screw rod 12, that is, can guarantee double wedge shape
It covers 2 outer rings and active connector 3 and is less than between two-sided 2 inner ring of wedge-shaped sleeve and solid lock screw rod 12 by the frictional force of follower link 4
Frictional force, when structure is in load condition, two-sided wedge-shaped sleeve 2 and active connector 3 and being detached from by follower link 4 is lost
Effect, so that structure shuts down, protects other components to be damaged.
Preferably, inner ring of the two-sided wedge-shaped sleeve 2 close to 11 one end of nut is equipped with cooperation chamfering 21, and the inner ring of the other end is equipped with
First keeps away a chamfering 22, and outer ring is equipped with second and keeps away a chamfering 23, avoids interference when cooperation, promotes assembly efficiency.
Preferably, two-sided wedge-shaped sleeve 2 is equipped with close to one end of nut and transition chamfering 13 and mating surface is less than transition
The side length of chamfering 13, so that transition, which is got home, has certain position-limiting action to two-sided wedge-shaped sleeve 2；It is highly preferred that two-sided wedge-shaped sleeve 2 leans on
One end of nearly nut and transition chamfering 13 are equipped with and mating surface is the 1/2 of 13 side length of transition chamfering, so that two-sided wedge-shaped sleeve 2
One end have that a certain distance is poor with nut 11, this ensures that after solid lock screw rod 12 safeguards surface abrasion, two-sided wedge-shaped sleeve 2 is thought
The direction of nut 11 also ensures after to be fitted close with the outer ring of solid lock screw rod 12, it is ensured that is reused, is reduced cost.
Preferably, two-sided wedge-shaped sleeve 2 is integrally formed by polytetrafluoroethylene (PTFE) material, and polytetrafluoroethylene (PTFE) has antiacid alkali resistant, resists
The characteristics of various organic solvents, is practically insoluble in all solvents, and chemical property is stablized, and lubricity is good, and service performance is steady
It is fixed.
Preferably, for the transmitting power of shaft coupling in 110KW or more, the diameter of solid lock screw rod 12 is M22, M24 or M26；
It is highly preferred that the transmitting power of shaft coupling, in 110KW or less, the diameter of solid lock screw rod 12 is M16 or M20, for different
Operating condition targetedly selects the connector of different size, had both guaranteed powerdriven reliable and stable, moreover it is possible to ensure apparatus overload
When, the other parts such as shaft coupling, retarder are protected in time.
In practical work process, it will first reapply after wedge bolt 1 and the assembly of two-sided wedge-shaped sleeve 2 and connect in shaft coupling,
Ripple pad 5 and stop nut 6 are installed in place, such composite fastener changes the single hinged bolts structure that tradition uses
Form solves the problems, such as that hinged bolts protective value is not in place, when transmitting power less than 110KW, is advised using diameter
The lesser wedge bolt 1 of lattice, when transmitting power and being greater than 110KW, using the biggish wedge bolt 1 of diameter specifications, for
Property setting, both guaranteed powerdriven reliable and stable, moreover it is possible to when ensuring apparatus overload, two-sided wedge-shaped sleeve 2 from wedge bolt 1 take off
Fall, cooperation failure, wedge bolt 1 is cut in active connector 3 and in time at the cooperation of follower link 4 so that equipment without
Method runs well, and driven guarantee equipment other component is not damaged, this structure is under normal operation, fastening maintenance one weekly
It is secondary, the workload of plant maintenance worker is reduced, extends maintenance period, and improve safety.
One embodiment of the utility model is described in detail above, but the content is only the utility model
Preferred embodiment should not be considered as limiting the scope of the present invention.It is all to be made according to application scope of the utility model
All the changes and improvements etc., should still belong within the patent covering scope of the utility model.
