HOW TO READ THIS MODEL

The system, explained.

A shaft coupling connects a driver-side shaft with a driven-machine shaft. Disc-coupling families use flexible-element packs; spacer arrangements place a central member between two packs. This original static assembly separates the bored hubs, six-layer lamina packs, spacer flanges and centre tube. Three hub-side and three spacer-side attachment locations alternate around each pack. Larger openings in the opposing flange provide visual bypass regions. Deliberate gaps expose the layers and shaft bores; no clamped contact, deformation or torque transfer is calculated. Compare the coupling with the separate bearing, seal and pump lessons: these components have different roles, and the independent models do not establish a matched machine.

Model scope and limits

Original invented static geometry: two shaft/hub envelopes, twelve separately named flat annular laminae in two packs, four flanges with alternating small/large geometric bores, hollow centre spacer, twelve hollow sleeves and separate smooth bolt/head/washer/bored-nut groups, two guard halves, two annular guard-end markers, four support/foot pairs. 105 named mesh instances include repeated laminae and joint hardware. No OEM CAD, figures, proprietary optimized profile, product dimensions, materials or ratings imported. Deliberate layer and shaft/hub gaps are teaching choices, not selected fits or clamped operating clearances. No keyway, shaft locking, threads, preload, torque/speed rating, misalignment/deflection/stress/fatigue/balance result, weld/manufacture, certified guarding/access protection, complete collision or engineering qualification. No installation, guard removal, operation or maintenance procedure.

GUIDED COMPONENT STUDY

Trace the system.

Read each explanation, then focus its component in the explorer. This is a learning route through the model, with no operating or maintenance sequence.

Identify the driver-side hub
The blue hub has a real bore around a separate shaft envelope. A deliberate gap makes that boundary visible. No key, clamp, interference fit or other qualified shaft engagement is supplied.
Distinguish the hub flange
Three smaller openings alternate with three larger bypass openings. Attachment identity is a teaching relationship, rather than proof of fit, contact, preload or torque transfer.
Inspect an individual lamina
This thin gold annulus is one of six separate layers at this end. Each has six true openings. The deliberate gaps and flat shape support inspection; they do not reproduce a selected pack product or operating clamped stack.
Compare the other pack
A second six-layer pack occupies a separate location beside the driven hub. There is no bending or misalignment simulation, and neither pack has a rated capacity.
Follow a hub-side attachment sleeve
The hollow sleeve spans the hub flange and lamina region. Its own bore surrounds a separate smooth bolt marker. The sleeve is an original geometric teaching element without a selected precision fit.
Find the alternating spacer attachment
This location attaches at the spacer flange instead of the hub flange. The opposing larger opening is separate. Alternating locations explain the conceptual sequence without calculating force distribution.
Inspect the bypass region
The opposing flange opening is deliberately larger around the hub-side joint envelope. Selected actual nut vertices clear its geometric radial envelope; that narrow check is not a complete contact or collision analysis.
Look through the centre member
The centre tube is hollow and lies between the two spacer flanges. The independent shaft segments stop outside it. No selected span, welded joint, balance or torque capacity is established.
Separate washer and nut roles
A bored hexagonal nut envelope sits beside a separate annular washer and smooth bolt. These visible openings establish no thread engagement, tightening value or preload.
Distinguish the guard from rotating components
This enclosure-shaped half has real inner and outer surfaces, independently selectable from the hub and disc regions. Reveal internals hides shell-layer parts. Guard certification, reach distances and access protection are absent.
Inspect the guard end boundary
The end-location annulus has a shaft opening. It is not a shaft seal or a qualified guarding boundary. The original poster omits both end markers to make the assembly readable.
Find an independent guard foot
This foot has a real anchor-position bore beside its support marker. The model supplies no anchor, foundation or structural design and no mounting procedure.
