Abstract
The utility model discloses a simple shaft coupling, which belongs to the field of mechanical transmission parts, and overcomes the defects that an existing shaft coupling is inconvenient to disassemble and assemble and has poor buffering and damping effects to a transmission shaft during work. The simple shaft coupling comprises two butt-joint hollow circular cylinder bodies, enclasping blocks, in which a rotation shaft can be loaded, are connected to the outer ends of the bodies, an annular elastic ring for connecting the two bodies is arranged between the two bodies, four installation holes uniformly distributed along the circumference are formed in the elastic ring, the end faces of the two circular cylinder bodies are respectively provided with two convex columns matched with the installation holes, and the elastic ring is embedded in the convex columns for clamping connection. The convex columns are arranged at both ends of the shaft coupling and are connected with each other by the annular elastic ring. The simple shaft coupling has a simple structure, a small size and a rotation clearance close to zero and is convenient to install and disassemble. By virtue of the simple shaft coupling, the axial offset of the transmission shaft can be effectively compensated during work, and vibration can be alleviated.
Description
Technical field
The utility model belongs to the mechanical transmission part field, and is especially relevant with a kind of simple and easy coupling.
Background technique
In mechanical transmission fields, adopt shaft joint to be in transmission connection between each transmission shaft.Common rigid coupling can't to transmission shaft buffering and vibration damping, be dismantled also pretty troublesome when work.When common cross universal coupling connected the rotating shaft of two fixing devices, coupling must match fully with two coupling shaft spacings; During coupling shaft in the middle of dismounting, must in advance one in two fixing devices first be folded down, just can take off the coupling of respective side, the coupling shaft in the middle of pulling down, dismounting inconvenience, and not good to transmission shaft buffering and effectiveness in vibration suppression during work.
The model utility content
The purpose of this utility model is intended to overcome the defective of existing coupling dismounting inconvenience, has buffering and damping effect when a kind of work is provided, and installation and removal are simple and easy coupling more easily.
For this reason, the utility model is by the following technical solutions: a kind of simple and easy coupling, the hollow circuit cylinder body that comprises two docking, the body outer end is connected to the piece of holding tightly of the rotating shaft of can packing into, it is characterized in that, described two docking cylindrical body hollows, be provided with the ring elastic ring that connects both between two bodies, elastic ring is provided with circumferentially uniform mounting hole of four edges, respectively be provided with two projections that coordinate with mounting hole on two cylindrical body end faces, described elastic ring is nested in clamping on projection, and is simple in structure, easily manufactured.Utilize the ring spring sheet of hollow will dock cylindrical body and be connected to become complete coupling, in the middle of coupling can move to, be convenient to the dismounting of jack shaft as axle sleeve on coupling shaft, again can the compensating axial skew; Utilize the distortion of elastic ring to cushion and alleviate the vibration that produces in transmission process.
As to technique scheme replenish and perfect, the utility model also comprises following technical characteristics.
The described piece of holding tightly is formed by connecting by fastening screw trip bolt by a pair of semicircle link, and is simple and reliable.
Use the utility model can reach following beneficial effect: projection is set and utilizes the elastic ring of annular to connect at coupling two ends, simple in structure, volume is little, has the revolution gap that goes to zero; In work, but the axial dipole field of effective compensation transmission shaft, alleviate vibration, and installation and removal are convenient.

Fig. 2 is the side view of Fig. 1.
Fig. 3 is the utility model coupling shaft schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
As depicted in figs. 1 and 2, the utility model comprises the hollow circuit cylinder body 2 of two docking, the projection 5 that two uniform settings are respectively arranged on the two corresponding end faces of body 2, line passes the end face center of circle, be nested with the elastic ring 3 of annular on projection 5, have the circumferentially uniform mounting hole corresponding with projection 5 of four edges on elastic ring 3, elastic ring 3 links together two cylindrical bodies 2, cylindrical body 2 outer ends are connected to holds piece 1 tightly, hold piece 1 tightly and be formed by connecting by fastening screw trip bolt 4 by a pair of semicircle link, the rotating shaft of can packing in it.
When the utility model uses, as shown in Figure 3, couple together by the rotating shaft with A, B two fixing devices of two novel Simple elastic coupling and an intermediate connecting shaft, when the installation or removal coupling, the fastening screw trip bolt at coupling two ends need only be unclamped, coupling just can axially move freely along coupling shaft, has solved existing cross universal coupling installation and removal hard problem; But the elastic ring on the while coupling is the axial dipole field of effective compensation transmission shaft at work, the vibration that buffering produces.
