Wear and Friction Characteristics of 65Mn Steel for Spike-Tooth Harrow

The friction and wear characteristics of spike-tooth material (65Mn steel) Spike-Tooth Harrow in a two-stage peanut harvester were studied this paper. tests pin disc on 65 manganese steel carried out the tribometer, then loss coefficient studied. was acquired by calculating mass before after experiment using an electronic balance. According to actual working environment spring-finger, four variable parameters are set up: load, speed, soil moisture type. pins under different loads, speeds environments. After wearing, worn surface observed scanning microscope mechanism experimental results show that increases with increase load decreases rotational speed same rotation number. Especially case sandy 20% moisture, maximum is achieved.
