Quick answer: Show the storage drum, output drum and intended transfer direction in the assembly drawing. Naming only clockwise rotation can be ambiguous.
How should the transfer direction be specified?
A clockwise view from one shaft end becomes counterclockwise from the other. Incorrect viewing conventions can produce a spring that is assembled in the wrong sense. Use a defined viewing datum and describe which drum gains strip during the working motion.
A practical verification method
Confirm the drawing convention with a marked assembly and verify travel without forcing an unapproved bend.
| Item | What to record | Purpose |
|---|---|---|
| Reference configuration | Part or assembly identity and drawing revision | Make comparisons traceable |
| Test conditions | Relevant position, direction and operating condition | Compare the same characteristic |
| Decision evidence | Confirm the drawing convention with a marked assembly and verify travel without forcing an unapproved bend. | Resolve the specific question before approval |
Use the result in an engineering request
Describe the observed condition and the required function separately. Include the relevant drawing revision and your results from the check above. If an acceptance limit has not been established, identify it as an open design input rather than treating a successful trial as approval.
