Abstract
The utility model discloses a diaphragm coupling which is used for connecting a driving shaft with a driven shaft and comprises a first half-coupling, a second half-coupling, an intermediate shaft, a first circular elastic part and a second circular elastic part. The first half-coupling is connected with the driving shaft, the second half-coupling is connected with the driven shaft, the intermediate shaft is arranged between the first half-coupling and the second half-coupling, one end of the intermediate shaft is connected with the first half-coupling by the first circular elastic part, and the other end of the intermediate shaft is connected with the second half-coupling by the second circular elastic part. The diaphragm coupling has the advantages that the diaphragm coupling is simple in structure and convenient to maintain, does not need to be lubricated and is light. Besides, the diaphragm is adaptable to various environments.
Description
Technical field
The utility model relates to a kind of coupling, relates in particular to a kind of diaphragm coupling.
Background technique
Coupling makes for various reasons its barycenter or principal inertia axis add shaft axis with it and does not overlap, to produce in the running the phenomenon of uneven centrifugal inertia force, centrifugal inertia idol power and dynamic deflection (vibration shape), this energy imbalance must cause the vibration of axle system, thereby shadow error, axle stand under load and the distortion, pedestal distortion, bearing wear, the temperature variation (expanding with heat and contract with cold) that produce affect the normal work and use life-span of machine, diaxon that coupling joins is owing to the many factors such as relative movement between foozle, installation, the parts produce relative displacement.Generally speaking, the diaxon relative displacement is difficult to avoid, but the direction of displacement that the axle under the different working condition is transmission to be produced, namely axially (x), radially (y), angle (a) and displacement amount is big or small different.Existing coupler structure more complicated, needs often lubricate, maintenance cost is high, and adaptability is strong not.
Summary of the invention
The purpose of this utility model has compact structure with regard to being to provide a kind of in order to address the above problem, do not need to lubricate, diaphragm coupling easy to maintenance.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model is used for connecting driving shaft and driven shaft, comprise the first half-coupling, the second half-coupling, jack shaft, the first ring elastic component and the second ring elastic component, described the first half-coupling is connected with described driving shaft, described the second half-coupling is connected with described driven shaft, described jack shaft places between described the first half-coupling and described the second half-coupling, one end of described jack shaft is connected with described the first half-coupling by described the first ring elastic component, and the other end of described jack shaft is connected with described the second half-coupling by described the second ring elastic component.
Further, be provided with several bolts hole on the circumference of described the first ring elastic component and described the second ring elastic component, the bolt hole of described the first ring elastic component becomes to interlock with the bolt hole of described the second ring elastic component and is spaced.
Further, described the first ring elastic component and described the second ring elastic component are the metal diaphragm group;
Described metal diaphragm group is copper film sheet group; Described metal diaphragm group comprises four metal diaphragms.
The beneficial effects of the utility model are:
The utlity model has simple in structure, elastic element the connection gapless, do not need to lubricate, easy to maintenance, balance is easy, quality is little advantage, and can adapt to different working environments.
