Hammer stone crusher can be said to be the most widely applied and the most frequently seen crushing machine in various lager-scaled engineering projects. Like jaw stone crusher and dryer machine, hammer stone crusher has a long development history. Confronted with the fast development of today's industry, mining machinery industry also needs to innovate. Our new design concept is more efficient, more energy-saving and more wear-resistant.
With regard to the main shaft of hammer stone crusher, reasonable structure and adequate strength are the basic requirements must be met. If the shaft is not strong enough, then plastic deformation or fracture failure may happen and the equipment will be unable to operate normally. For the traditional design method of hammer stone crusher, the design of the shaft is generally completed in accordance with production experience and tedious manual calculation.
1. Choose materials according to the job requirements of hammer crusher. The carbon structural steel, alloy steel and nodular cast iron are the commonly used materials for shaft. Hammer crusher shaft is more made of alloy steel.
2. Make use of torsional strength to estimate the basic diameter of the shaft.
3. Design the structure of the shaft according to the overall structure requirements, and reasonably locate and fasten the spare parts on the shaft.
4. Check and calculate the strength of the shaft and judge whether the strength of the minimum life section can meet the requirements or not. If not, we should change the material or modify the structure to achieve the job requirements.
