Handle
 |
Handles are frequently used in hand-operated devices (clamps, fixtures).Although there are many standard (commercial) configurations for handles and knobs it is a good practice to have some handle design in your archives. |
Tongue and Groove
 |
Torque transmission, shaft alignment, position locking and others are some examples of numerous applications where a non rotating assembly is needed. The tongue and groove design is ideal where there is a lack of space. |
Shoulder (low cost design)
 |
Shoulders provide a positive rest for components in fixed joints or an abutment for axial displacement of parts in movable connections. Usually are made as a feature on the shaft. A low cost design for light parts and low forces is presented in this article. |
Spring guiding stem
 |
Springs are very useful in mechanical engineering. In order to increase the life of a compression spring, correct guiding of the spring must be provided. |
Keyway for square-ended key
 |
Keys are usually made from stock size rectangular bar (structural steel). Rectangular bars produce square-ended keys which could bind at the closed end of a round-ended keyway. How to make them not to bind; |
Shaft locking
 |
Another method for locking a shaft and preventing it from turning is with a parallel pin (dowel pin). This method is ideal for small and light weighted components. |
Shaft locking-screw lock retainer
 |
Another method of locking a shaft is with a screw lock retainer. The shaft is totally secured by means of a dog point or a round end shaped set screw. |
Shaft rotation control
 |
A shaft could be totally or partially controlled for rotation. In total rotation control the shaft is non-rotational. In partial rotation control a shaft can rotate by a certain amount of angle in order to perform a specific function. |
Tension spring end holder
 |
Numerous applications in machinery require springs (tension, compression and torsion). Design solutions for guiding, holding and adjusting the spring must be provided in order to achieve functionality and failure proofing operation. |
Linear micro adjustment
 |
Micro adjustment is a useful feature at mechanism and fixture assemblies. Unknown final position, rotation or linear movements must be regulated at assembly in order to work or clamp the work piece properly. This article describes a linear micro adjustment. |
