The universal coupling can ensure coaxiality of two shafts, achieves a centring function of the universal coupling, can quickly return to a required range when deviating from a required angle range, and has a good damping effect.
Description
Technical field
The utility model relates to a kind of coupling, is specifically related to a kind of Hooks coupling universal coupling with elastic element with spacing return function.
Background technique
Hooks coupling universal coupling can make two connector elements connect with changing angle, links to each other with axle usually.It can make diaxon not at same axis, exists under the situation of axis angle to realize that the diaxon that connects turns round continuously, and transmitting torque and motion reliably.Angle is in 5 °～45 ° scopes.Hooks coupling universal coupling has bigger angular compensatory ability.But the centering poor performance of present Hooks coupling universal coupling then may can't guarantee the stable of working position because swing speed is very fast if be installed in swing axis one end, influences workmanship, even is difficult to finish predetermined work.And buffering and damping performance are relatively poor, and be bigger to equipment damage in vibration environment, needs frequent maintain and replace part, the labor intensive financial resources.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model is, provides a kind of and can guarantee cardan shaft centering performance and damping performance, and have the Hooks coupling universal coupling of spacing return function.
In order to realize above-mentioned task, the utility model adopts following technological scheme to be achieved:
A kind of Hooks coupling universal coupling with elastic element with spacing return function, comprise two connector elements and a crossed universal shaft, each connector element is provided with two universal-joint forks, be processed with a crossed universal shaft mounting hole on each universal-joint fork, crossed universal shaft is installed in described four crossed universal shaft mounting holes two connector elements are assembled together and constitutes a Hooks coupling universal coupling, be processed with at described each universal-joint fork and stretch out tongue, between two universal-joint forks, be provided with for stretch out the block that tongue has cooperated spacing return effect, the both sides of the block vertical with universal-joint fork are respectively arranged with cushion pad.
The utility model also has following technical characterstic:
Described connector element adopts the axle head connector element.
Described connector element adopts the connector element that comprises that flange and flange connector element constitute.
Hooks coupling universal coupling of the present utility model can guarantee the coaxality of diaxon, realizes the centering effect of Hooks coupling universal coupling, and when departing from the angular range of requirement, can the fast return claimed range, have damping effect preferably; Universal joint structure of the present utility model is simple, and is easily manufactured, and processing cost is lower, is suitable for required angle and changes less device.

Below in conjunction with drawings and Examples particular content of the present utility model is done explanation in further detail.
Embodiment
Below provide specific embodiment of the utility model, need to prove that the utility model is not limited to following specific embodiment, all equivalents of doing on present techniques scheme basis all fall into protection domain of the present utility model.
Defer to technique scheme, extremely shown in Figure 6 as Fig. 1, a kind of Hooks coupling universal coupling with elastic element with spacing return function, comprise two connector elements and a crossed universal shaft 2, each connector element is provided with two universal-joint forks 3, be processed with a crossed universal shaft mounting hole 5 on each universal-joint fork 3, crossed universal shaft 2 is installed in described four crossed universal shaft mounting holes 5 two connector elements are assembled together and constitutes a Hooks coupling universal coupling, be processed with at described each universal-joint fork 3 and stretch out tongue 4, between two universal-joint forks 3, be provided with for stretch out the block 6 that tongue 4 has cooperated spacing return effect, the both sides of the block 6 vertical with universal-joint fork 3 are respectively arranged with cushion pad 7.
Connector element adopts axle head connector element 1 or adopts the connector element that comprises that flange plate 8 and flange connector element 9 constitute.
Cushion pad 7 has the effect of damping and centering return, be not limited only to rubber cushion blocks, can be the cushion pad that any elastomeric cushion material is made, under the situation that the centering return is had relatively high expectations, the cushion pad of selecting for use harder elastomeric cushion material to make, require under the not higher situation cushion pad of selecting for use softer elastomeric cushion material to make at the centering return.
Crossed universal shaft 2 adopts the crossed universal shaft of existing plug-in type structure, to guarantee the smooth assembling of two connector elements.
Be processed with on the top of universal-joint fork 3 and stretch out tongue 4, between two universal-joint forks 3, be provided with for stretch out the block 6 that tongue 4 has cooperated spacing return effect, this stretches out acting as of tongue 4 and block 6 and Hooks coupling universal coupling is carried out radially spacing, prevents because the amplitude of fluctuation that effect such as inertia causes is excessive.
For the Hooks coupling universal coupling that directly is connected with axle head, axle head connector element 1 is deferred to the processing mode of related domain routine, bottom at axle head connector element 1 has through hole, and tail end inside has keyway, and axle head connector element 1 and axle are by bolt, axle head baffle plate or key connecting.For passing through flange plate 8 and the joining Hooks coupling universal coupling of axle, defer to the processing mode of related domain routine equally, tail end and flange plate 8 at flange connector element 9 pass through Bolt Connection, the bottom of flange plate 8 has through hole, tail end inside has keyway, and flange plate 8 and axle are by bolt, axle head baffle plate or key connecting.
Because stretch out the position-limiting action of tongue 4 and block 6, universal coupling all can not carry out the swing of wide-angle on four direction.And because cushion pad 7 has certain elasticity, can play cushioning effect, reduce the vibrations of Hooks coupling universal coupling.When the connector element of Hooks coupling universal coupling turned an angle, rubber cushion blocks produced resistance to it, can reach to get back to meta faster, and carry out spacing among a small circle.
