Detailed Description

The pull rod type metal spring coupling of the present invention will now be described in greater detail with reference to the schematic drawings in which preferred embodiments of the present invention are shown, it being understood that those skilled in the art may modify the invention herein described while still achieving the advantageous effects of the present invention. Accordingly, the following description should be construed as broadly as possible to those skilled in the art and not as limiting the invention.

The invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.

As shown in fig. 1, an embodiment of the present invention provides a pull rod type metal elastic coupling, which includes two joints 1 for mounting a driven shaft and a driving shaft respectively, and a metal elastic pull rod 2 located between the two joints 1;

the metal elastic pull rods 2 are multiple, the metal elastic pull rods 2 are annularly arranged, and two ends of the metal elastic pull rods 2 are movably connected with the two connectors 1 through movable hinge parts 3 respectively.

In this embodiment, through a plurality of metal elasticity pull rods 2 that the annular set up between two joints 1, cooperation activity articulated elements 3 for the whole antitorque square that has of shaft coupling and automatic ability of rectifying for can satisfy the user demand under the high rotational speed scene better.

In one embodiment, specifically, the articulated part 3 includes a reamed hole bolt 31, a self-locking nut 32 and an oil-retaining bearing 33, the self-locking nut 32 is matched with the threaded end of the reamed hole bolt 31, the oil-retaining bearing 33 is installed at the end of the metal elastic pull rod 2, and the inner side of the oil-retaining bearing 33 is matched with the end of the reamed hole bolt 31 far away from the threads of the reamed hole bolt. In the present embodiment, the movable connection between the metal elastic pull rod 2 and the two joints 1 can be realized by using a movable hinge 3.

Specifically, referring to fig. 2, mounting holes 21 for mounting the oil-retaining bearing 33 are formed through both sides of the metal elastic pull rod 2, and both ends of the oil-retaining bearing 33 extend out of the mounting holes 21; the joint 1 is provided with a joint hole 11 which is matched with one end of the hinged hole bolt 31 far away from the thread.

The hinged hole bolt 31 passes through the connecting hole 11 and the oil-containing bearing 33 to be connected with the self-locking nut 32, so that the connection between the two joints 1 and the metal elastic pull rod 2 is realized, when the hinged hole bolt is used, the two joints 1 are respectively connected with the driven shaft and the driving shaft, after the driving shaft is started, the metal elastic pull rod 2 is stirred by torque through the joint 1 connected with the driving shaft, the self-locking nut 32 is in movable fit with the oil-containing bearing 33, and the self-locking nut 32 can be self-locked at a proper position, so that the hinged hole bolt can flexibly center and freely correct the deviation. Because the plurality of metal elastic pull rods 2 are annularly arranged, the cross section of each metal elastic pull rod 2 can be in a better molded surface of the resultant force of tensile stress and bending moment stress, the strain of the metal elastic pull rods 2 is larger, the generated reaction force is smaller, and better torque resistance is realized.

Preferably, the reamed hole bolt 31 sequentially passes through the engagement hole 11 and the oil bearing 33 to be in threaded connection with the self-locking nut 32. Through this kind of design, can be so that can take off metal elasticity pull rod 2 under the condition that need not remove both ends equipment after metal elasticity pull rod 2 fatigue life arrives, it is convenient to maintain.
