The outer wall of the pipe body 11 is provided with a guide protrusion 111; the protrusion 61 is arranged in the middle part of the lower surface of the gland 6; 62.

The upper surface of the gland 6 is provided with a threaded hole 63, and the traction machine is detachably connected to the threaded hole 63 through bolts.

The lower wall of the gland 6 vertically compresses the second elastic element 5 on the pressure plate 4 .

Both the first elastic element 2 and the second elastic element 5 are made of metal rubber, and the density of the first elastic element 2 is 1.2-2.5 times that of the second elastic element 5 .

The use and principle of the three-way vibration isolator of the elevator traction machine provided by the utility model:

The machine foot of the traction machine is threadedly connected with the threaded hole 63 through the bolt, so that the traction machine is detachably connected with the three-way vibration isolator of the elevator traction machine, which facilitates the disassembly and assembly of the traction machine.

The vibration of the traction machine is divided into vibrations in Z-axis, X-axis and Y-axis directions. The Z-axis vibration is transmitted from the gland 6 to the pressure plate 4, the first elastic element 2 and the base 1 in sequence, and the Z-axis vibration is transmitted from the gland 6 When it is transmitted to the pressure plate 4, the Z-axis vibration is also transmitted to the second elastic element 5, so the Z-axis vibration is mainly buffered by the first elastic element 2, and auxiliary by the second elastic element 5.

The first elastic element 2 only deforms in the vertical direction, and the vibration of the traction machine is transmitted from the gland 6 to the three-way vibration isolator of the elevator traction machine, because the gland 6, the pressing plate 4, the first The elastic element 2 and the base are connected sequentially, so the first elastic element 2 buffers the vibration in the vertical direction of the traction machine; the cooperation between the first guide groove and the guide plate 3 makes the pressure plate 4 only move vertically, so that the first elastic The component 2 does not bear the vibration of the traction machine in the horizontal direction; the relative sliding stroke of the first guide groove and the guide plate 3 is the buffer distance of the pressure plate 4 in the vertical direction. When the gland 6 is subjected to the horizontal vibration of the traction machine, because its projection 61 is surrounded by the second elastic element 5, and the second elastic element 5 is sandwiched between the pipe body 11 and the projection 61, so the second elastic Element 5 can buffer the vibration of the traction machine in the horizontal direction. Therefore, the structure of the three-way vibration isolator of the elevator traction machine provided by the utility model not only buffers the vibrations in the three axial directions in the space of the traction machine, but also distributes the vibrations in the three axial directions to the two elastic elements. Buffering prevents an elastic element from being easily damaged and aged due to multi-directional vibration, so that the three-way vibration isolator of the elevator traction machine can maintain excellent shock absorption capacity for a long time.

The above is only an embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent transformations made by using the utility model specification and accompanying drawings, or directly or indirectly used in related technical fields, are all the same. The theory is included in the patent protection scope of the present utility model.
