Description
Technical field
The utility model relates to a kind of Hooks coupling universal coupling, relates in particular to a kind of disc type synchronous 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 is big, be eliminated gradually, the substitute is cross-axle universal shaft coupling, although cross-axle universal shaft coupling has many good qualities, but, when its jack shaft and driving shaft, when the interaxial angle of driven shaft axis unequal or three are not positioned at same plane, the momentary angular speed that driving shaft and driven shaft will occur is asynchronous, and can not keep driving shaft and driven shaft to rotate synchronously, make it be not suitable at high rotating speed, use under the situation of Angular Displacement.
The model utility content
The purpose of this utility model is to provide a kind of disc type synchronous universal coupling, rotates technical problem asynchronous, restricted application to solve existing cross-axle universal shaft coupling driving shaft and driven shaft.
For achieving the above object, the utility model provides a kind of disc type synchronous universal coupling, comprise: driving shaft, driven shaft and a minor axis, the driving shaft axle head is provided with the slot of two positions symmetry, and the axle head inwall is provided with arc groove, and the driven shaft axle head is a disk, disk and arc groove socket, disc centre is provided with a jack, and minor axis is arranged in jack, and is connected with two slots.
According to the described disc type synchronous universal coupling of the utility model preferred embodiment, its jack is a circular hole.
According to the described disc type synchronous universal coupling of the utility model preferred embodiment, its jack is the long-round-shape hole, and this center, long-round-shape hole is a circular hole, and expands the formation long-round-shape along Circularhole diameter gradually to both ends of the surface.
According to the described disc type synchronous universal coupling of the utility model preferred embodiment, this coupling also comprises a back-up ring, this back-up ring and driving shaft socket.
The utility model also provides a kind of disc type synchronous universal coupling, comprise: driving shaft, driven shaft and a minor axis, the driving shaft axle head is provided with first jack of two positions symmetry, and the axle head inwall is provided with arc groove, the driven shaft axle head is a disk, disk and arc groove socket, and disc centre is provided with one second jack, minor axis is arranged in second jack, and pegs graft with two first jacks.
According to the described disc type synchronous universal coupling of the utility model preferred embodiment, its second jack is the long-round-shape hole, and this center, long-round-shape hole is a circular hole, and expands the formation long-round-shape along Circularhole diameter gradually to both ends of the surface.
According to the described disc type synchronous universal coupling of the utility model preferred embodiment, this coupling also comprises a back-up ring, back-up ring and driving shaft socket.
The beneficial effects of the utility model are: driving shaft is connected with driven shaft by minor axis, and driving shaft rotates by minor axis and drives the driven shaft rotation.When no angle rotated between driving shaft and the driven shaft, minor axis rotated simultaneously with driving shaft, drove driven shaft and rotated.When having angle to rotate between driving shaft and the driven shaft, outside minor axis rotates simultaneously with driving shaft, also to-and-fro motion in the driving shaft slot, and self rotates simultaneously, and then realized that driving shaft and driven shaft rotate synchronously.The utility model also can use under the situation of high rotating speed, Angular Displacement, and Applicable scope is extensive.

Embodiment
Below in conjunction with accompanying drawing, specify the utility model.
Embodiment one
See also Fig. 1 to Fig. 5, a kind of disc type synchronous universal coupling, comprise: driving shaft 1, driven shaft 2 and minor axis 3, driving shaft 1 axle head is provided with the slot 11 of two positions symmetry, and the axle head inwall is provided with arc groove 12, and the driven shaft axle head is provided with a disk 21, disk 21 and arc groove 12 sockets, disk 21 centers are provided with jack 211, and minor axis 3 is arranged in jack 211, and are connected with two slots 11.
Jack 211 is arranged on disk 21 centers, itself and disk 21 concentric settings, and as shown in Figure 5, in this example, jack 211 adopts circular holes.
In this example, need to prove that disc type synchronous universal coupling of the present utility model also can be at driving shaft 1 arranged outside one back-up ring, shield ring sleeve is connected to the axle head of driving shaft 1, and minor axis 3 is blocked, and can prevent effectively that minor axis 3 from coming off, and using effect is better.
Above jack 211 is set to circular hole, and still, this jack 211 is not defined as circular hole, and it also can be arranged to oblong hole, and this center, long-round-shape hole is a circular hole, and expands the formation long-round-shape along Circularhole diameter gradually to both ends of the surface.If jack 211 is set to slotted hole, when having angle to rotate between driving shaft 1 and the driven shaft 2, outside minor axis 3 rotates simultaneously with driving shaft 1, also to-and-fro motion in the slot 11 of driving shaft 1, and self rotates and back and forth rocks in the long-round-shape hole simultaneously, realizes that driving shaft 1 has also increased interaxial angle when rotating synchronously with driven shaft 2.
Embodiment two
A kind of disc type synchronous universal coupling, comprise: driving shaft, driven shaft and a minor axis, driving shaft axle head are provided with first jack of two positions symmetry, and the axle head inwall is provided with arc groove, the driven shaft axle head is a disk, disk and arc groove socket, disc centre are provided with one second jack, and minor axis is arranged in second jack, and peg graft with two first jacks, this second jack is oblong hole, and this center, long-round-shape hole is a circular hole, and expands the formation long-round-shape along Circularhole diameter gradually to both ends of the surface.In the present embodiment, the difference with embodiment one is that the driving shaft axle head is provided with first jack and replaces slot, and second jack adopts the long-round-shape hole.Other structures of present embodiment are all identical with first embodiment with working principle, do not repeat them here.
