Reduce Stress Concentration
Maximum reducing the stress concentration is the primary measures and main way for improving the fatigue strength of the main shaft. Because the mutation of shape and size is the structural causes of stress concentration, in order to reduce the stress concentration, we should reduce as much as possible mutations in shape and size of the main shaft, and make it smooth, uniform change. In the inevitable to produce the large stress concentration, we can adopt the load reducing groove to reduce the impact of stress concentration.
Improve The Surface Quality
Increasing the fatigue strength of spindle can first considerate to improve the surface quality, such as in the spindle surface force higher area, we can process more smoothly. For the corrosive shaft section, on its surface, we can take appropriate protective measures, which greatly improved the surface quality of spindle.
Stipulate The Strict Inspection Requirement
For the important shaft section, we should stipulate the strict inspection method and requirements on the design drawings. For example, the spindle surface is possible dimensions, and the preventive measures should be taken to be as much as possible to reduce or eliminate, because this plays an important role on improving the fatigue strength of the spindle.
Take The Cooling, Reducing Load Measurement
The spindle plays a transmission role in impact crusher work. Operation under low stress running long, cooling and reducing load measures can significantly improve the degree of fatigue.
The Selection Of Suitable Materials
Spindle material usually select the carbon steel and alloy steel. Most of the steel shaft uses the rolling round steel and forgings. Some are the direct use of round steel. Compared with the alloy steel, carbon steel has a low price and the low sensitivity of stress concentration. But we can use the method of heat treatment and chemical heat treatment to improve its wear resistance and fatigue strength. So the carbon steel manufacturing spindle is particularly widespread.
