Abstract

The utility model relates to an improved shaft coupling disassembling structure. A shaft coupling is provided with two groups of fastening units, wherein each fastening unit is respectively provided with a first disk-shaped assembly and a second disk-shaped assembly, and one of the first disk-shaped assembly and the second disk-shaped assembly is provided with a plurality of second screw holes for a plurality of second bolts to insert; a spiral theory is used for generating large push force to push the first disk-shaped assembly or the second disk-shaped assembly to simply separate the two disk-shaped assemblies of the shaft coupling, and thus the disassembling procedure of the shaft coupling saves time and labor. The bolt is used for pushing and separation, which avoids external force knocking parts to result in damage and enhances the durability of the shaft coupling.

Description

Improved coupling detaching structure

Technical field

The utility model relates to a kind of coupling, relate in particular to a kind of effectively avoid prior art when dismounting to the injury that part caused, and allow the improved coupling detaching structure of coupling unloading process time and labour saving.

Background technique

See also Fig. 5, be existing coupling, this kind coupling has two first disc assemblies 8, the tapered portion 81 of these two first disc assemblies 8 is inserted in the taper hole 91 of two second disc assemblies 9 respectively, and with a plurality of lock bolts 821 stretch through respectively each first disc assemblies 8 perforation 82 and screw in the screw 92 of each second disc assemblies 9, and make the taper hole 91 of second disc assemblies 9 and tapered portion 81 drive fits of first disc assemblies 8, come packing rotating shaft 83.9 of these two second disc assemblies link with a bellows 93, reach the function of transmission two rotating shafts 83.

Because of producing above-mentioned closely cooperating after the coupling locking, so the utmost point was not quick detachable when desire was separated this device, though take out lock bolt 821, still often need by external force, as use instruments such as iron hammer to knock sleeve 8 and it could be separated with flange 9, therefore easily cause the damage of part, the durability of single unit system and practicability are greatly reduced, so above-mentioned structure has improved necessity in fact.

Embodiment

Seeing also Fig. 1 to Fig. 4, is the selected example structure of the utility model shown in the figure.

See also Fig. 1 to Fig. 3, it is first embodiment of the present utility model, and it mainly is to have the bellows 4 of two groups of packing unit 1, in order to link two groups of packing unit 1 and two fixed covers 41 of fixing these bellows 4 two ends; Each packing unit 1 has one first disc assemblies 11, one second disc assemblies 12, a plurality of first bolt 2 in order to each first disc assemblies 11 of locking and each second disc assemblies 12 and a plurality of in order to back down second bolt 3 of each first disc assemblies 11 respectively.

Wherein, these two first disc assemblies 11 all have a tapered portion 111 and a perforation 112 that supplies rotating shaft 7 to insert respectively, these two tapered portion 111 have the axial joint-cutting 113 in three places respectively, and the periphery of the perforation 112 of these two first disc assemblies 11 has a plurality of perforation 114 and three second screws 124 that are equally spaced that are equally spaced respectively.

These two second disc assemblies 12 have a taper hole 121 respectively, insert for each tapered portion 111, and two second disc assemblies 12 outer periphery have a linking department 122 respectively, link for this bellows 4.Again, the periphery of the taper hole 121 of these two second disc assemblies 12 has a plurality of first screws 123 and a plurality of second screws 124 respectively.

The utility model is when packing rotating shaft 7 into, earlier each second bolt 3 is screwed in two second disc assemblies 12 respectively, after again the tapered portion 111 of these two first disc assemblies 11 being inserted the taper hole 121 of two second disc assemblies 12, stretch through the respectively perforation 114 of two first disc assemblies 11 of each first bolt 2, and screw in locking in first screw 123 of two first disc assemblies 12, after these two first disc assemblies 11 are closely cooperated with these two second disc assemblies 12, can each tapered portion 111 of packing, the joint-cutting 113 that makes it dwindles and clamps rotating shaft 7.

Of paramount importancely be, the utility model is when dismounting rotating shaft 7, and the effect that institute should reach for ease of comparison and understand, sees also Fig. 3, shows among the figure that the right side is the still clamped state of rotating shaft 7, and the left side then is that rotating shaft 7 is no longer clamped, and the state that can withdraw from.At first, after each first bolt 2 withdrawed from each second disc assemblies 12 from each first disc assemblies 11, this moment, the state of closely cooperating was still kept in each first disc assemblies 11, second disc assemblies 12 and two rotating shafts 7.Then, the utilization spiral motion can produce the principle of big end thrust, because of spiral is the distortion on " inclined-plane ", utilizes in the inclined-plane action, and the weight of the power of can reducing friction and the part that takes in sail reaches the labour-saving effect because of reducing energy loss.So, go pushing tow first disc assemblies 11 by screwing out each second bolt, 3 generation thrust, first disc assemblies 11 can be separated easily with second disc assemblies 12.At this moment, joint-cutting 113 reinstatements of the tapered portion 111 of two second disc assemblies 11 can be taken out two rotating shafts 7, and easily, the labour-saving finishes disassembling section.

Certainly, still there are many examples in the utility model, therebetween the only variation on the details.See also Fig. 4, right side place is the clamped state of rotating shaft 53 among the figure, and the left side is then no longer clamped for rotating shaft 53, and the state that can withdraw from.It is second embodiment of the present utility model, and the combination of its first disc assemblies 51 and second disc assemblies 52 and utilization principle are same as the previously described embodiments, repeat no more.Different is on each first disc assemblies 51, equidistantly is provided with second screw 523 of a plurality of perforations, and respectively with one second bolt 6, revolves through each second screw 523 to second disc assemblies, 52 directions.

During desire dismounting rotating shaft 53, then each second bolt 6 of turn in regular turn supports it and compels second disc assemblies 52.So, the reaction force of 52 pairs second bolts 6 of second disc assemblies be can borrow, and the taper hole 521 of second disc assemblies 52 and then the clamping of the countershaft 53 that gets loose gradually the tapered portion 511 of first disc assemblies 51 withdrawed from.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.

In sum, the utility model is on structural design, use practicability and cost benefit, it is required to meet industry development fully, and the structure that is disclosed also is to have unprecedented innovation structure, have novelty, creativeness, practicability, the regulation that meets relevant novel patent requirement is so mention application in accordance with the law.
