What are the main principles of mechanical principles and mechanical parts design?
7. part surface quality requirements and corrosion protection requirements;8. cost factors;......There are many other factors.
4. weight requirements, often in the hands of the parts required lightweight, in the case of mechanical strength to meet the choice of small proportion of materials;5. service life requirements are temporary or long-term use, intends to use a year or 10 years?6., the influence of environmental temperature, environmental temperature changes will affect the expansion of parts;
Factors to consider when designing mechanical parts:1. the function of the parts, the parts in the equipment, and its uses. Is the part shaft or instrument housing or support seat?2. the load of the parts, according to the load or according to the strength requirements, determine the brand of material.3. heat treatment conditions, heat treatment and no heat treatment conditions, the election of different materials;
