Latest Basics of Design Engineering Content

A number of different shock absorber designs are available, but the fundamental operation of each is the same.

More than 50% of total production time is spent on assembly or fastening.

These requirements should be considered in selecting the best insert: shear strength of parent material, operating temperature, load requirement, presence of vibratory loads, ease of installation, and installed cost.

These screws are used to cut or form a mating thread when driven into preformed holes.

Stepping motors offer many advantages.

The frictional properties of any plain bearing depend on the lubrication system.

A built-in locking feature develops full locking action as soon as these nuts are engaged with the bolt threads.

Plate or anchor nuts have one or more lugs projecting from the base of the threaded body.

Alloys, or blends of PPE and polystyrene in various proportions, are marketed under the tradenames of Noryl and Prevex (General Electric).

Experts say the single most important advance in PM motor technology was the introduction of rare-earth magnetic materials in the mid-1970s.

For maximum power transfer, switch contacts should have zero resistance.

These fasteners should be used when repeated access to a component is necessary.

Generally, ball bearings are less expensive than roller bearings for small bores and light loads, whereas roller bearings are less expensive in the larger sizes and heavier loads.

Fluid-handling or transfer devices are not basically concerned with the modulation or transfer of power, but only with the movement of fluid.

Inserts act as a tapped hole in both open and blind locations.
