Description
Technical field
The utility model relates to a kind of Hooks coupling universal coupling, relates in particular to a kind of axle head and puts round bar formula Hooks coupling universal coupling.
Background technique
In mechanical system, when angular displacement, see various forms of coupling being arranged in action through regular meeting.In the heavy machinery driving mechanism, what use at first is steel slide block type coupling, because this coupling quick abrasion, steel consumption are big, be eliminated gradually, the substitute is cross universal coupling, although cross universal coupling has many good qualities, but it the momentary angular speed of driving shaft and driven shaft can occur when single use asynchronous, thereby rotational speed and torque is all changed, and this variation meeting is along with the change of angular displacement greatly and sharply strengthens, therefore, cross universal coupling is not suitable for using under the situation of high rotating speed, Angular Displacement.For solving the shortcoming that above-mentioned coupling exists, people have been developed synchro-nizing universal coupling with ball and sacker again, synchro-nizing universal coupling with ball and sacker has solved the problem that above-mentioned coupling exists, but, synchro-nizing universal coupling with ball and sacker comprises all multiple components such as steel band hoop, outer cover, ball cage, star sleeve and snap ring, complex structure makes its manufacturing procedure complexity, cost height.In addition, existing coupling all is only limited to automobile-used, restricted application.
In sum, there is the technical problem of complex structure, manufacturing procedure complexity, cost height and restricted application in coupling of the prior art.
The model utility content
The purpose of this utility model is to provide a kind of axle head simple in structure, that processing technology is simple, with low cost and applied widely to put round bar formula Hooks coupling universal coupling.
For achieving the above object, the utility model provides a kind of axle head to put round bar formula Hooks coupling universal coupling, comprise: primary shaft, driven shaft, some round bars and some round bar links, the outer wall of primary shaft one end is an arc surface, the inwall of driven shaft is an arc surface, primary shaft is connected by the outer wall arc surface of primary shaft and the inwall arc surface of driven shaft movingly with driven shaft, joint at primary shaft and driven shaft, the outer wall of driven shaft is provided with the some round bars perpendicular to driven shaft, primary shaft is provided with some round bar links, the round bar link is arranged on the round bar both sides, is connected movingly with round bar.
Put round bar formula Hooks coupling universal coupling according to the described a kind of axle head of the utility model preferred embodiment, its primary shaft and driven shaft diaxon axis angle can change.
Put round bar formula Hooks coupling universal coupling according to the described a kind of axle head of the utility model preferred embodiment, its primary shaft, driven shaft are the hollow tubular axle, and round bar and round bar link can be arranged on primary shaft inside.
Put round bar formula Hooks coupling universal coupling according to the described a kind of axle head of the utility model preferred embodiment, its primary shaft is a solid shaft.
Put round bar formula Hooks coupling universal coupling according to the described a kind of axle head of the utility model preferred embodiment, the round bar girth member is installed on its driven shaft.
Compared with prior art, the utlity model has following advantage:
1, this axle head is put round bar formula Hooks coupling universal coupling and has been cancelled component such as the steel band hoop of synchro-nizing universal coupling with ball and sacker, outer cover, ball cage, star sleeve and snap ring, simple in structure, manufacturing procedure is few, with low cost.
2, this axle head put round bar formula Hooks coupling universal coupling except that be used for automobile-used, also can be used on the drilling rod of rig, Applicable scope is extensive.
Description of drawings
Fig. 1 is that schematic perspective view cuts open in the office that the utility model axle head is put round bar formula Hooks coupling universal coupling;
Fig. 2 is the schematic perspective view of the utility model axle head when putting the primary shaft of round bar formula Hooks coupling universal coupling and driven shaft two axis angle being arranged.
Embodiment
Below in conjunction with accompanying drawing, specify the utility model.
See also Fig. 1 to Fig. 2, a kind of axle head is put round bar formula Hooks coupling universal coupling, comprise primary shaft 1, driven shaft 2, some round bars 3 and some round bar links 4, the outer wall of primary shaft 1 one ends is an arc surface, the inwall of driven shaft 2 is an arc surface, primary shaft 1 is connected by the outer wall arc surface of primary shaft 1 and the inwall arc surface of driven shaft 2 movingly with driven shaft 2, joint at primary shaft 1 and driven shaft 2, the outer wall of driven shaft 2 is provided with two round bars 3 perpendicular to driven shaft 2, primary shaft 1 is provided with four round bar links 4, wherein, per two round bar links 4 are arranged on round bar 3 both sides, are connected movingly with round bar 3.Need to prove, adopt two round bars 3 and four round bar links 4 in the present embodiment, but the utility model is not limited thereto, in actual applications, can select the quantity of round bar 3 and round bar link 4 according to the actual loading intensity of Hooks coupling universal coupling, a round bar 3 can be set, two above round bars 3 also can be set, the quantity of round bar link 4 is according to the quantity setting of round bar 3.Therefore, more than adopting two round bars 3 and four round bar links 4 is an example, and is not used in qualification the utility model.In addition, in this example,, the round bar girth member can also be installed on driven shaft 2 for increasing the intensity of round bar 3.
In this example, primary shaft 1 and driven shaft 2 are the hollow tubular axle, and round bar 3 and round bar link 4 can also be arranged on primary shaft inside except that the above-mentioned outer wall that is separately positioned on driven shaft 2 and primary shaft 1.But primary shaft 1 is not defined as the hollow tubular axle, and its arc end also can be set to solid, and when the arc end of primary shaft 1 is set to when solid, round bar 3 and round bar link 4 can not be arranged on primary shaft inside.
