Abstract

Spacing flexible diaphragm shaft coupling of ball socket axial constitutes including power input half -coupling (1), power take off end half -coupling (2), input sheath (3), output sheath (4), middle section (5) and diaphragm group (6). The both ends of middle section (5) are connected with input sheath (3), output sheath (4) respectively. Power input half -coupling (1) is connected with input sheath (3) through diaphragm group (6). Power take off end half -coupling (2) is connected with output sheath (4) through diaphragm group (6). Processing has sphere (7) on power input half -coupling (1) and power take off end half -coupling's (2) shaft hub. Processing has and sphere (7) complex ball socket on the shaft hub of input sheath (3) and output sheath (4). The utility model discloses simple structure installs and removes the convenience, can absorb not centering of the certain angle that exists of unit, parallel.

Description

Ball-and-socket axial limiting flexible membrane coupling

Technical field

The utility model relates to a kind of coupling, and especially a kind of ball-and-socket axial limiting flexible membrane coupling, belongs to unit high-performance connection for transmission technical field.

Background technique

The diaphragm of diaphragm coupling has fabulous flexibility when being spring Stainless Sheet Steel.When connected machine diaxon becomes angle, parallel disalignment or axial motion (exist angle, parallel, axially misalign), diaphragm flexible distortion absorption misaligns, ensure unit smooth operation, thus in turbomachinery unit, be able to extensive use.But some machines are because of structural limitations or other reasons, do not have thrust-bearing, rotor is to needing during the machine vibration on opposite by the thrust-bearing constraint location of coupling by the latter.Tackle this demand, both at home and abroad release multiple axial limiting coupling, they have a common shortcoming to be: although can axial limiting, spacingly become rigid coupling simultaneously, namely can not absorb that unit necessarily exists to Parallel misalignment.

Model utility content

For above-mentioned the deficiencies in the prior art, the utility model provides one and can elongate and can not press short, and can absorb the novel ball-and-socket axial limiting flexible membrane coupling of angle, Parallel misalignment.

For achieving the above object, the technical solution adopted in the utility model is: ball-and-socket axial limiting flexible membrane coupling, comprises power intake half-coupling (1), clutch end half-coupling (2), input end sheath (3), output terminal sheath (4), middle node (5) and diaphragm group (6).The two ends of middle node (5) are connected with input end sheath (3), output terminal sheath (4) respectively.Power intake half-coupling (1) is connected with input end sheath (3) by diaphragm group (6).Clutch end half-coupling (2) is connected with output terminal sheath (4) by diaphragm group (6).The propeller boss of power intake half-coupling (1) and clutch end half-coupling (2) is processed with sphere (7).The propeller boss of input end sheath (3) and output terminal sheath (4) is processed with the ball-and-socket coordinated with sphere (7).

Preferably, described sphere (7) is identical with the radius of curvature of ball-and-socket, and its sphere centre is positioned on the central point C of diaphragm group (6).

Feature of the present utility model and beneficial effect:

1. the utility model proposes a kind of elongation and can not press short axial limiting flexible membrane coupling, structure is is simply installed and removed conveniently.

2. the utility model ball-and-socket axial limiting flexible coupling does not affect the angle, the Parallel misalignment that absorb unit and necessarily exist.

3. the utility model smooth running, not other strength, extends the life-span of unit filmatic bearing.

Embodiment

As shown in Figure 1 and Figure 2: ball-and-socket axial limiting flexible membrane coupling, comprises power intake half-coupling 1, clutch end half-coupling 2, input end sheath 3, output terminal sheath 4, middle node 5 and diaphragm group 6.The two ends of middle node 5 are connected with input end sheath 3, output terminal sheath 4 respectively.Power intake half-coupling 1 is connected with input end sheath 3 by diaphragm group 6.Clutch end half-coupling 2 is connected with output terminal sheath 4 by diaphragm group 6.The propeller boss of power intake half-coupling 1 and clutch end half-coupling 2 is processed with sphere 7.The propeller boss of input end sheath 3 and output terminal sheath 4 is processed with the ball-and-socket coordinated with sphere 7.The sphere of half-coupling is identical with the radius of curvature of the ball-and-socket of sheath, and its sphere centre is positioned on the central point C of diaphragm group 6.The sphere of half-coupling and the ball-and-socket precision-fit of sheath, can realize axial limiting and rotation, can absorb angle, Parallel misalignment simultaneously.
