Case Study on Improvements for Agricultural Machinery Shaft Breakage

In July 2024, a customer gave feedback that Theirs The axis of the combine harvester There was a rupture during the field operation, and the end customers were very anxious about the fact that the ripe grain could not be harvested smoothly. They initially thought that it might be the raw material of the shaft 40CrNiMoA or the heat treatment process that did not meet the requirements. We have received Their help the broken axis was analyzed at the first time, and it was concluded that it was not Raw materials and There is a problem with the process, but it is designed by the customer.SeasonIt is not taken into account the complex working conditions of the equipment.And one-way force fatigue Hidden dangers, customer requirements Whole Tall Hard Degree heat treatment leads to the high hardness of the core, which is easy to produce Tired Break,After analysis We suggest adopting Whole Adjust the quality plus Surface The process of induction quenching replaces the original heat treatment Overall high hardness The process makes the core Hardness Reduce And the outer surface hardness is high, which meets the wear resistance., and sent it to the customer according to the suggested process.The new sample achieved excellence in the second field experiment.Bear fruit The feedback of.
