Abstract
The utility model discloses a half-coupling device. The half-coupling device comprises a shaft sleeve and a clamping plate connected with one end of the shaft sleeve. The central axis of the shaft sleeve coincides with the central axis of the clamping plate. Four connection bosses are arranged on the end surface of the clamping plate and arranged on the same circumferential surface, the cross section of each connection boss is quadrilateral, and each side is of an arc-shaped structure. The clamping plate is provided with connection holes formed between the connection bosses and the outer circumference of the clamping plate. According to the half-coupling device, the connection performance of a coupling device is good, and therefore normal operation of equipment is guaranteed.
Description
Technical field
The utility model relates to coupling technical field, is specifically related to a kind of half-coupling.
Background technique
Coupling is comprised of two half-couplings, is used for connecting two axles (driving shaft and driven shaft) in different institutions, makes it common rotation with the mechanical parts of transmitting torque.General power engine is mostly connected by means of coupling and working machine, is that engineering goods axle is the most frequently used coupling member of transmission.
The connection of coupling is mainly by the connection that cooperatively interacts of the link on two half-coupling chucks, and is provided with elastic component between two half-couplings, and it is connected firmly.And in prior art, link on half-coupling chuck mostly is trapezium structure, the face that two half-couplings contact with elastic component is plane, in coupling running, frictional force between two half-couplings of cause and elastic component is little, easily cause connection loosening, thereby affect the normal operation of equipment.
Model utility content
The purpose of this utility model is to overcome above shortcoming, and a kind of half-coupling that can strengthen switching performance is provided.
The technical solution of the utility model is:
A kind of half-coupling, comprise axle sleeve and the chuck being connected with described axle sleeve one end, the central axis of described axle sleeve and the central axes of described chuck, on the end face of described chuck, be provided with four connection boss, described four connection boss are arranged on same circumferential surface, and the cross section of described each connection boss is quadrilateral, and described every limit is arcuate structure, on described chuck, be provided with attachment hole, described attachment hole is arranged between described connection boss and the excircle of described chuck.
Further, described four connection boss are evenly distributed on same circumferential surface.
Further, the arc radian of described connection boss both sides size is ∏/3, radian-2, ∏/3 radians.
Further, the inwall of described axle sleeve is provided with flat key groove.
The half-coupling that the utility model provides, has the following advantages:
The half-coupling that the utility model provides, can strengthen the switching performance of coupling.The half-coupling that the utility model provides, comprise axle sleeve and the chuck being connected with described axle sleeve one end, the central axis of described axle sleeve and the central axes of described chuck, on the end face of described chuck, be provided with four connection boss, described four connection boss are arranged on same circumferential surface, the cross section of described each connection boss is quadrilateral, described every limit is arcuate structure, on described chuck, be provided with attachment hole, described attachment hole is arranged between described connection boss and the excircle of described chuck.The connection boss cross section arranging on chuck is quadrilateral, and each limit is arcuate structure, and four side faces that connect boss are cambered surface, when two half-couplings connect, reduced the relative sliding between two half-couplings, thereby the switching performance of coupling is better, guarantees the normal operation of equipment.
On chuck, be provided with attachment hole, described attachment hole is arranged between described connection boss and the excircle of described chuck, has stablized the switching performance of two half-couplings, has thoroughly solved the loosening problem of the coupling causing because of the slip between two half-couplings.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment's technological scheme, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the three-dimensional structure diagram of the utility model half-coupling;
Fig. 2 is the plan view of Fig. 1;
Reference character: 1-axle sleeve, 2-chuck, 3-connects boss, and 4-connects the arc of boss side, 5-attachment hole, 6-flat key groove.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment
In conjunction with Fig. 1, Fig. 2, a kind of half-coupling, comprise axle sleeve 1 and the chuck 2 being connected with axle sleeve 1 one end, the central axes of the central axis of axle sleeve 1 and chuck 2, is provided with 3, four connection boss 3 of four connection boss and is arranged on same circumferential surface on the end face of chuck 2, each cross section that connects boss 3 is quadrilateral, and every limit is arcuate structure, is provided with attachment hole 5 on chuck 1, attachment hole 5 is arranged on and connects between boss 3 and the excircle of chuck 2.Chuck 2 is as the connected element of coupling;
The cross section that connects boss 3 is quadrilateral, and every limit is arcuate structure, four side faces that connect boss are cambered surface, when two half-couplings connect, between two half-couplings, be provided with elastic component, corresponding elastic component, for being also corresponding globoidal structure, has reduced the relative sliding between two half-couplings, thereby the switching performance of coupling is better, guarantee the normal operation of equipment.
On chuck, 1 is provided with attachment hole 5, and attachment hole 5 is arranged on and connects between boss 3 and the excircle of chuck 1, has stablized the switching performance of two half-couplings, has thoroughly solved the loosening problem of the coupling causing because of the slip between two half-couplings.
In the present embodiment, four connection boss 3 are evenly distributed on same circumferential surface, and half-coupling and corresponding elastic component are easy to process, and two supporting half-couplings are when connect, and attended operation also more for convenience.
In the present embodiment, the arc 4 radian sizes that connect boss side are ∏/3, radian-2, ∏/3 radians, and the central angle that makes arc is 60 °-120 °, within the scope of this radian, connect boss 3 and can closely cooperate with elastic component, further reduce the slip of supporting two half-couplings and elastic component.
In the present embodiment, the inwall of axle sleeve 1 is provided with flat key groove 6, and when coupling is connected with driving shaft or driven shaft, on driving shaft or driven shaft, correspondence is provided with flat key groove, flat key is connected with the flat key groove on axle with the flat key groove 6 of sleeve lining respectively, and axle sleeve is connected closely with axle.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing, be equal to replacement etc., within all should being included in protection domain of the present utility model in protection domain of the present utility model.
