The relations between the oil-temp. protection setting value of lubrication system and the main shaft cracking of SXHD-7 superweight cone crusher

The internal relations between the oil-temp.protection setting value of lubrication system and the main shaft cracking of SXHD-7 superweight cone crusher are analyzed in the paper,the oil-temp.protection value should be set along with the different ambient temperature according to the practical production, to edectively reduce the crack of main shaft.
