Product Reliability
Reliability is an extensive subject, earning a separate review. Related to the reliability of parts and components, lifetime calculations determinates the fault frequency of the whole. Reliability is a mathematical procedure, which gives indications of the device reliability. This subject is taught in schools. The problem is that students do not have an experience in equipment design criteria, or products.
Reliability is understood as the ability to operate without interruption. Reliability is an important element in the design and operation, which customers value in assessing the quality of products and services. The traditional way is the use of safety factors and standard solutions, and learn to use the experience. Reliability of the first planned product is possible to transfer via the proportionality to the other same series products. In principle, the once determided reliability in one product of the series, is included in other products.
A mechanical failure of the body occurs often in machine constructions, whereby the strain of matter should also be noted. We calculate the fatigue and reliability in matter and we transfer the reliability within the product line. Not everyone has had the opportunity to design product series, supply the renewable products and spare parts for several decades old equipment, and obtain feedback.
We transfer through the comparison procedure the reliability of one product to another. We do this, for example by calculating the dynamic load value of large bearing, by knowing the value of the smallest bearing. Focussing, we define bearing's outside measurements, which fill up the requirements of the bearing dynamic C value. This, of course, should not be able to do. At the same time we calculate the whole range of values. For example, the bearing value C is associated with the reliability, since the bearing lifetime is calculated as agreed in the operating hours of the load ratio.
