A form-fit, form-locking or form-closed connection is a type of mechanical connection between two parts (example: screw and screwdriver), wherein these parts due to their forms interlock and block each other along at least one defined linear or rotational direction.
In military usage, fit to receive or fitting "for but not with" describes a weapon or system which is called for in a design but not installed or is only partially installed during construction, with the installation completed later as needed.
The more exact fit of the key and keyway also reduces play, and stress concentrations in, and improves the reliability of the key. An additional advantage is a stuck key can be removed from a shaft with a hammer blow, the circular profile will push the key out of the slot, as opposed to a standard key which will need to be pushed axially, or ...
This is an independent suspension design using two wishbone-shaped arms to locate the wheel. Each arm has two mounting points to the subframe and one joint at the knuckle, and in the case of TAK-4 independent suspension system these arms are of unequal length. The shock absorber and spring mount to the lower arm to control vertical movement ...
The tightness of fit is controlled by amount of interference; the allowance (planned difference from nominal size). Formulas exist [2] to compute allowance that will result in various strengths of fit such as loose fit, light interference fit, and interference fit. The value of the allowance depends on which material is being used, how big the ...
Locking mechanisms keep bolted joints from coming loose. They are required when vibration or joint movement will cause loss of clamp load and joint failure, and in equipment where the security of bolted joints is essential. A prevalent test for the self-loosening behaviour is the Junker test. Jam nuts
When you buy a bottle of vitamins from a nutrition store, you’ll probably notice a best-by date on the bottom of the jar. But that inscribed number isn’t a hard-and-fast rule—there is some ...
