Abstract

The utility model discloses a quincuncial elastic coupler for connecting a driving shaft and a driven shaft. The quincuncial elastic coupler comprises a first coupling half, a second coupling half and quincuncial elastic parts. The first coupling half is connected with the driving shaft. The second coupling half is connected with the driven shaft. End faces of the first coupling half and the second coupling half are respectively provided with quincuncial double wedges. The quincuncial elastic parts are placed between the first coupling half and the second coupling half. Petals of the quincuncial elastic parts are placed in a gap of the double wedges between the first coupling half and the second coupling half. The number of the petals of the quincuncial elastic parts is eight. The number of the double wedges of the first coupling half and the second coupling half is eight. The quincuncial elastic parts are monomer cast nylon elastic parts or polyurethane elastic parts. The quincuncial elastic coupler has the advantages of being tight in structure, reliable in operation, large in transmission torque range, and overladen in protection function.

Description

Quincunx elastic coupler

Technical field

The utility model relates to a kind of coupling, relates in particular to a kind of Quincunx elastic coupler.

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 just is to provide in order to address the above problem the Quincunx elastic coupler that a kind of torque range with compact structure, reliable operation, transmission is large, have overload protection function.

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 and quincunx elastic component, described the first half-coupling is connected with described driving shaft, described the second half-coupling is connected with described driven shaft, the end face of described the first half-coupling and described the second half-coupling is provided with quincunx double wedge, described quincunx elastic component places between described the first half-coupling and described the second half-coupling, and the petal of described quincunx elastic component places in the space between the double wedge of described the first half-coupling and described the second half-coupling.

Further, the petal of described quincunx elastic component is eight lobes; The double wedge of described the first half-coupling and described the second half-coupling is eight.

Further, described quincunx elastic component can be the monomer cast nylon elastic component; Described quincunx elastic component can also be elastic polyurethane spare.

The beneficial effects of the utility model are:

The torque range that the utlity model has compact structure, reliable operation, transmission is large, have advantages of overload protection function.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

As depicted in figs. 1 and 2, the utility model is used for connecting driving shaft (not shown) and driven shaft (not shown), comprise the first half-coupling 1, the second half-coupling 2 and quincunx elastic component 4, the first half-coupling 1 is connected with driving shaft, the second half-coupling 2 is connected with driven shaft, the end face of the first half-coupling 1 and the second half-coupling 2 is provided with quincunx double wedge 3, quincunx elastic component 4 places between the first half-coupling 1 and the second half-coupling 2, and the petal 5 of quincunx elastic component 4 places in the space between the double wedge 3 of the first half-coupling 1 and the second half-coupling 2.

As depicted in figs. 1 and 2, the petal 5 of quincunx elastic component 4 is eight lobes; The double wedge 3 of the first half-coupling 1 and the second half-coupling 2 is eight; Quincunx elastic component 4 is the monomer cast nylon elastic component, also can adopt elastic polyurethane spare.

In conjunction with Fig. 2, in the utility model working procedure, the petal 5 of quincunx elastic component 4 places in the space between the end face double wedge 3 of the first half-coupling 1 and the second half-coupling 2, makes to form very closely between them to connect, its transmission better effects if is worked more stable; In addition, the elasticity of quincunx elastic component 4 also helps to cushion the rigid impulse power in the transmission process.

The coupling that focuses on providing by quincunx elastic component transmission of the present utility model if only change size or the structure of quincunx elastic component, then all should be considered as invading right of the present utility model.
