Preloading
| Глоссарий терминов смазочных материалов |
Procedures employed during assembly and mounting to remove all looseness or play in a bearing, usually performed on shafts or spindles in machine tools and precision machines that must rotate without clearance in either the axial or radial direction. preloaded bearings are not used where deflection is excessive. pre-lubed bearings: bearings lubricate by the manufacturer to preserve their integrity during storage.

Procedures, английский
Standard, detailed steps that prescribe how to perform specific tasks.
Deflection, английский
- The deference between a tire's unloaded or free radius and the loaded radius.
- Vertical distance between the chord and the skyline, measured at midspan; frequently expressed as a percentage of the horizontal span length (22).
- The displacement of a structural member or system under load.
- Отклонение
- The ricochet of a ball after it hits a player.
- The tendency of a ship from her true course; the departure of the magnetic needle from its true bearing, when influenced by iron or the local attraction of the mass. in artillery, the deviation of a shot from the direction in which it is fired. the term is usually reserved to lateral deviations, especially those resulting from irregular causes—those constant ones due to the regular motion of rifled projectiles coming under either of the designations “constant deflection,” “derivation,” borrowed from the french, or “drift,” from the americans. these latter, according to the direction usually given to the rifling in the present day, all tend away to the right, though they include some subordinate curves not yet distinctly determined.
- [1] gunnery term for the angle between the line-of-sight to the target and the line-of-sight to which the gun must be pointed to compensate for movement, wind, etc. [2] deviation of a compass needle caused by local magnetic influence, especially on a ship.
- A change in the intended course of a borehole produced intentionally or unintentionally by various conditions encountered in the drill hole or by the operational characteristics of the drilling equipment used. also called deviation.
- Отклонение от прямого направления отклонение магнитной стрелки; отклонение стрелки (приборов)
- See static tire deflection,
Manufacturer, английский
- (завод-) изготовитель
- Производитель
- Изготовитель; производитель
- Товаропроизводитель
- Birfield transmissions ltd.

Pressure angle (gears), английский
Angle between the line of action and a line tangent to both pitch circles. this angle remains constant with involute form teeth at any point in the contact path. common pressure angles are 14.5° and 20°; when stronger teeth are needed, larger angles are used. pressure angles increase with center distance. pressure, atmospheric: see normal pressure.
Precipitation number, английский
(astm d-91) the number of milliliters of solid matter precipitated from a mixture of oil and petroleum solvent under specified conditions; chiefly used to determine the presence of asphalts in semi-refined or black oils, or to examine sludge in used oils.
