The Design Guidelines To Prevent Precision Machinery Parts From Losing Their Work Capability

DALIAN, China - Sept. 24, 2023 - PRLog -- 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.

2. Stiffness Criteria:

The deformation of parts can affect the working efficiency of the entire device. Therefore, the stiffness of the parts must meet the requirements to avoid excessive deformation. The design of stiffness should consider the geometric shape of the part, the elastic modulus of the material, and the force applied to ensure that the part maintains the desired shape and position during operation.

3. Fatigue Life Criteria:

Mechanical parts are subjected to fatigue loading during continuous working cycles over long periods of time. To prevent fatigue-induced fracture of parts, the fatigue life of the parts must be calculated based on the fatigue performance and working cycle conditions of the material to ensure that no fracture occurs within the specified lifetime.

4. Surface Criteria:

The quality of the part surface directly affects the occurrence of wear and surface fatigue. The roughness, hardness, and lubrication of the surface need to be designed according to the working conditions to reduce friction, wear, and corrosion.

5. Temperature Criteria:

High temperature environments can affect the performance of materials and the working capacity of mechanical parts. Therefore, it is necessary to select appropriate materials and thermal insulation measures according to the temperature changes in the working environment to ensure that the parts can work properly at different temperatures.

6. Material Selection Criteria:

The selection of materials should consider factors such as strength, stiffness, wear resistance, and corrosion resistance. Select the appropriate material to meet the working requirements based on the working environment and the forces and pressures that the parts are subjected to.
