Shear stability/mechanical shear stability
| Глоссарий терминов смазочных материалов |
Measure of the change in consistency of a grease after it has been subjected to prolonged shearing by means of a mechanical device like a grease worker (10,000 strokes) or a roll test; the percentage change in penetration values is an indicator of shear stability.

Consistency, английский
- The degree to which a semisolid material such as grease resists deformation. (see astm designation d 217.) sometimes used qualitatively to denote viscosity of liquids.
- That property of a liquid adhesive by virtue of which it tends to resist deformation
- Последовательность
- The ability of a transaction to change a system from one consistent state to another consistent state.
- The desirable property of an estimator whereby the calculated value of a parameter converges upon the true value as the sample size increases.

Silicones, английский
Generic term for a class of synthetic lubricants that replace carbon atoms with a chain of alternating oxygen and silicon; also known as siloxanes. these fluids are water-resistant polymers with very high viscosity indexes, excellent fluidity at low temperatures and good oxidation and thermal stability at higher temperatures. they do not have high load-carrying capacity.
Servo valve, английский
A high-performance directional and flow control valve usually operated by a torque motor; similar to a proportional valve but superior in terms of frequency response and hysteresis.
