Membrane compensating coupling and hole anchor connection

A technology of coupling and compensating parts, applied in the direction of couplings, elastic couplings, mechanical equipment, etc., can solve the compensation of the radial change due to the difficulty of manufacturing the compensating parts, the low mass moment of inertia, and limiting the large axial length of the coupling and angle change compensation to achieve the effect of improving deformation potential, low moment of inertia mass, and large compensation ability

Problems solved by technology

This design allows a low mass moment of inertia; however, manufacturing reasons limit the axial length of the coupling and thus the possibility of compensating large radial and angular changes
The shape of the compensator is also difficult to manufacture

Embodiment 1

[0030] The first embodiment shows the membrane compensation coupling 1 in the installed state between the elastically fitted motor 2 and the drive unit 3 . The coupling 1 is of block construction and consists of three elements. It comprises a first compensator 4 with two opposing membranes 5 and 6 , a second compensating element 7 with two opposing membranes 8 and 9 , and an intermediate tube 10 embedded between them. The individual elements are manufactured in one piece from fiber composite material. The compensating elements 4 and 7 are always made of resin embedded with glass and / or carbon fibers, depending on the intended use. Although the maximum axial length of the compensating elements 4 and 7 is limited for manufacturing reasons, the intermediate tube 10 can achieve dimensions adapted to the different installation situations.

[0031]The membranes 5 , 6 and 8 , 9 of the compensating elements 4 and 7 are connected to one another at their outer circumferences by substa...

Embodiment 2

[0037] figure 2 A second embodiment of a membrane compensating coupling is shown in which the compensating elements 4 and 7 are of the same design as the first example. When the distance between the engine and the transmission is long, it is sometimes necessary for the intermediate pipe 10 to pass through the partition wall 27 . In this case, a slightly raised metal or plastic ring 28 is additionally provided on the outer circumference of the intermediate pipe 10 made of fiber composite material, a metal or plastic ring with a radially split sealing ring 29 connected to the partition wall 27 A plastic ring forms a flexible sliding seal.

[0038] During the installation process, the intermediate pipe 10 is now installed first. The compensating elements 4 and 7 are then moved radially into their connected position. Their connection to the intermediate pipe 10 is the same as in the first embodiment. Since the connecting flanges 12 and 15 separated from the intermediate pipe ...

Embodiment 3

[0040] image 3 A third embodiment is shown in , where a compensating element can be designed as an elastic connecting element 30 . The elastic connection 30 comprises two annular membranes 31 and 32, which are always made of fiber composite material and can be provided with curvature. Elastomer 33 is placed between membranes 31 and 32 and is preferably vulcanized onto the membranes. The membrane 32 facing the central tube 10 has a radially inwardly protruding connecting flange 34 which is of the same design as the connecting flanges 13 and 14 of the two preceding exemplary embodiments. Here too, the connection to the intermediate pipe 10 is via a hole anchor connection 22 . In the embodiment shown, the other membrane 31 is fixed at its outer end to an intermediate flange 35 which may be fixed to the output element of the motor or the input element of the driven unit. However, instead of the intermediate flange 35, it is also possible to connect the membrane 31 to the motor...

Abstract

The membrane compensating coupling comprises a first compensating element (4) made of fiber composite material with two membranes (5, 6) facing each other, a second compensating element (7) and an intermediate Tube (10). The first and second compensating elements (4, 7) each have a radially inwardly protruding connection flange (13, 14) at their end pointing toward the central tube (10). Therefore, there is provided a membrane compensating coupling comprising at least two membranes made of fiber composite material which is easy to manufacture and install while having a low inertia, allowing large angular, radial and axial compensations and also having a flexible shaft length. The invention also describes a hole-anchor connection particularly suitable for this coupling.

Description

technical field [0001] The invention relates to the field of membrane compensating couplings made of fiber composite material. The invention also relates to a hole-anchor connection for connecting flanges made of fiber composite material, which is especially suitable for use in membrane compensation couplings. Background technique [0002] With at least one deformable membrane made of fiber composite material, the membrane compensation coupling allows compensation of angular and length deviations that exist between machine parts that rotate during operation, such as the output element of the engine and the input element of the drive unit, such as the transmission device. Since the life of a membrane made of fiber composite material depends primarily on the deformations that occur thereon, displacements of the installed machine parts should be avoided as much as possible in the stationary installation state. Compensating couplings comprising a membrane made of fiber composi...
