Perhaps a hundred different types of couplings can join rotating drives when there is just a small misalignment between shafts (3°). But designs with misalignments approaching 10° or more leave just ...

A ROTATING shaft can exhibit torsional vibration when, because the dynamic coefficient of friction is less than the static value, the frictional force at the bearings supporting the shaft decreases as ...

Smaller, streamlined electronics make lubricant-free, low-friction magnetic bearings feasible for more rotating machines. • Magnetic bearings support rotating shafts in five axes without solid or ...

Bores are sealed with ‘O’ rings' sited in grooves, (figure 1). The ‘O’ rings' are usually of toroidal shape (i.e. circular cross section) and are regulated by BS 1806 and BS 4518. Figure 1. ‘O’ Ring ...
