The Design Guidelines To Prevent Precision Machinery Parts From Losing Their Work Capability
Precision mechanical parts may fail to operate normally during operation due to various reasons, which directly affects the performance and reliability of the mechanical device. These abnormalities include fracture, excessive deformation, wear, and surface fatigue. In order to ensure the normal operation of parts, a series of work capacity criteria or design criteria have been developed, which serve as the basic guiding principles for the design of precision mechanical parts, aiming to ensure the stable operation and service life of the parts.
1. Strength Criteria:
This is an important criterion to ensure that parts do not break during the working process. The strength requirements of parts must meet the various forces, pressures, and loads they are subjected to, as well as the possible impacts and vibrations that may occur. Strength calculations need to consider the mechanical properties and stress distribution of the material to ensure that the parts will not break under normal operating conditions.
These work ability criteria or design criteria play a crucial role in the design and manufacture of precision mechanical parts.
