Embodiment Construction

[0017] see first figure 1 and figure 2 , the coupling includes two diaphragm plate members 1 and 2 having central hub parts 11 and 21, respectively. The socket part 11 on the right-hand member 1 is substantially cylindrical and is provided with a splined portion 12 on the outside. A socket part 21 on the other member 2 has a cylindrical portion 22 extending axially and terminated by a transversely extending mounting flange 23 having four mounting holes 24 at its corners. Each member 1 and 2 also includes an integral diaphragm plate 15 and 25 extending radially outwardly from the respective hub 11 and 21 respectively and joined together around its outer periphery. In use, the splined portion 12 is inserted into the drive input of a gear or the like (not shown), while the flange 23 is bolted to a similar flange at one end of a torque tube or other rotatable drive member. (not shown) on. In this way, the drive from the torque tube is transferred to the gear or other driven c...

Abstract

One aspect of the present invention relates to a diaphragm coupling having first and second diaphragm plates (15, 25) that are joined together around their outer edges. Each diaphragm plate 15, 25 has a central, axially-extending hub (11, 21). The hub (11) of the first plate (15) supports within it a pin member (30) having an outwardly projecting shoulder (31, 36) at each end adapted to engage an internal shoulder (117) on the hub (11) of the first plate (15) at one end and an internal shoulder (215) on the hub (21) of the second plate (25) at the other end so as to limit axial separation of the two hubs (11, 21) from one another.

Description

technical field [0001] The present invention relates to diaphragm couplings. Background technique [0002] Diaphragm couplings are used to provide a constant velocity connection between two rotating components that allows for small amounts of angular displacement between the components. The coupling consists of two parallel flexible plates joined together around their outer edges and joined at a central mount to respective rotating members. Alternatively, the plates may be joined together in the center and joined to the rotating part at their outer edges. When there is an angular displacement between the two rotating parts, the two plates flex to accommodate it. Among the advantages that these couplers have is that they have no moving parts and require little or no maintenance. Examples of membrane couplings are described in US4133188, US3959988, US4802882, US6394387, US4191030, US4411634, EP0627571, US6183317, US6050865, US5755622 and US5407386. [0003] Membrane coupli...
