Embodiment
Referring to the elastomer coupling of the present embodiment of Fig. 1~9, including the first half a coupler 1, the second half a coupler 2, bullet
Property body 5, the first half-shells 4, the second half-shells 6, as shown in Fig. 2 in the relative of the first half a coupler 1 and the second half a coupler 2
The convex portion face of the convex portion of circle distribution, the first half a coupler 1 and the second half a coupler 2 is respectively arranged with face；Such as Fig. 1 and figure
Shown in 4, elastomer 5 is enclosed on outside the first half a coupler 1 and the second half a coupler 2, and the inner side of elastomer 5 is provided with double wedge 8, double wedge
8 two sides are raised arc, according to the difference of arcuate shape, with the side of elastomer double wedge 8 and the tie point of elastomer 5
Locate to arrive at 0 ° for point of contact, the span of the angle 11 between the tangent line of the side of double wedge 8 and the tangent line of the inner circumferential circle of elastomer 5
Between 90 °, in the present embodiment preferable angle be 30 °, 45 ° or 60 °, other angles can also, can be selected according to being actually needed
Select, mainly solve the shortcomings that right angle heel teeth is easy to wear in the prior art, extend the life-span of elastomer.Each two elastomer double wedge
Form groove between 8, the convex portion of the first half a coupler 1 and the second half a coupler 2 is embedded in the groove between two elastomer double wedges 8；
A cut is provided with elastomer 5, during later maintenance, is not dismantling the first half a coupler 1 and the second half a coupler 2
In the case of, it is necessary to when unloading elastomer 5, when pulling open the cut on elastomer 5, elastomer 5 can be made from the first half a coupler 1
Taken out with the second half a coupler 2.
Shell is provided with outside elastomer 5, shell is made up of the detachable convenient half-shells 6 of first half-shells 4 and second, the
The both ends of one half-shells 4 and the second half-shells 6 are equipped with connector, the connector at the both ends of the first half-shells 4 and the second half-shells 6
The connector at both ends aligns trip just, and is detachably connected by fastener.In the present embodiment, the structure of shell such as Fig. 5
It is shown, cage connection part 401 is provided with wherein one end of the first half-shells 4, the width of cage connection part 401 is the first half-shells
The half of 4 width, the head 4002 of cage connection part is cylinder design, and head 4002 is provided with bolt hole in the direction of the width
4003, for being set through the junction 4001 of fastener, cage connection part 401 and the first half-shells 4 for two-sided spill arc-shaped
Meter, circular arc are tangential on the head 4002 of the first half-shells 4 and cage connection part simultaneously, and the other end of the first half-shells 4 is also provided with
There is a same cage connection part 401, the size and shape of the second half-shells 6 is identical with the first half-shells 4.The fastening of shell
Part both can be bolt or buckle, as shown in figure 3, preferably using the first bolt 3 and the second bolt in the present embodiment
7 are attached；The inner circumferential of shell is provided with a circle groove 10, and the width of groove 10 is identical with the width of elastomer 5 or is slightly larger than
The width (purpose being slightly larger than be for convenience by casing on elastomer 5) of elastomer 5, to fixed elastomer 5, prevent
It slides laterally；The outer surface of elastomer 5 sets the breach 9 of 1 or more than 1, the inner surface setting of the shell and
The projection that the breach 9 matches, generally, the outer surface of elastomer 5 set 1 breach 9 to play fixed work
With, but in order that installation is more convenient, in the present embodiment, as shown in Fig. 2 the outer surface of elastomer 5 sets 2 of face to lack
Mouthfuls 9,2 projections that inner surface setting and the breach 9 of the shell match play that to prevent that elastomer 5 from occurring with shell relative
The effect radially slided.
When needing to change elastomer 5 during use, it is only necessary to back out bolt 3 and bolt 7, then pull open bullet
Property body 5 on cut so that cut opens certain width, you can by elastomer 5 from the first half a coupler 1 and the second half
Taken out on shaft coupling 2；Then the cut of new elastomer 5 is pulled open, the groove of new elastomer 5 is fitted into the first half
Shell, is then fixed on the outside of new elastomer 5, makes elastomer 5 by the convex portion of the face of 1 and second half a coupler of shaft coupling 2
Just in the groove 10 of shell inner circumferential, while make the projection of inner surface of outer cover just embedding with the breach 9 of the outer surface of elastomer 5
Close, finally screw on bolt 3 and bolt 7, whole Renewal process is convenient and swift, it is not necessary to good to mounting and adjusting the first half
The half a coupler 2 of shaft coupling 1 and second moves, it is not required that carries out centering tune to the center of drive end and driven end equipment
It is whole, avoid due to alignment deviation and influence the normal work of equipment, the problem of even resulting in shut-down (breakdown) mainteance.
In the present embodiment, specially designed arc-shaped gear elastomer, substantially increases shaft coupling and integrally depends on elastomer
Supported for the alignment deviation that equipment provides, it is easier for installation, without higher maintenance preciseness, plug and play, reduce peace
Dress and maintenance cost.Meanwhile the shortcomings that right angle heel teeth originally most easy to wear also is evaded falling by the design of arc-shaped gear, more preferable
While keeping the rotation of two axles, extending elastic body life time, elastomer root portion is provided with pinnacle angle, on the premise of stress is reduced,
Ensure elastic body life time, the triangle formed with root portion is hollow, there is provided good support force, can keep elastomer in motion state
In stability.
Other shell especially employ can two halves separation design, the Center tongue in both sides, in the interior table of shell
Face sets the projection that the breach with outer elastomeric surface matches, and to fixed elastomer, two parts of shell, which are done, detachably to be set
Meter, it is frequently necessary to break shell in order to change into pieces when changing elastomer originally, now need to only turns on screw, opening shell can be more
Change elastomer so that the replacement frequency of shell reduces, more scientific and reasonable, also reduces the maintenance cost of product.
