A whole-engineering-machine-based method for evaluating extreme pressure and antiwear properties of grease, comprising: injecting (S200) the grease onto a key bearing pin of an engineering machine and causing the engineering machine to operate without load; causing (S210) the engineering machine to operate under a load of 10% to 150% rated load at least once; recording (S220) whether an abnormal noise occurs during the effective operation of the key bearing pin under different loads, and determining a calculated noise peak generated under a corresponding load; viewing and analyzing a wear condition of a surface of the key bearing pin, and a noise peak condition of the key bearing pin; and issuing (S230) a whole-engineering-machine-based evaluation report of the extreme pressure and antiwear properties of the grease according to the wear condition and the noise peak condition, wherein the engineering machine is caused to operate once under the load of 10% to 150% rated load for 0.5 min to 100 h, and the calculated noise peak generated under the corresponding load is determined according to a following formula: Max dB 1 + dB 2 + dB 3 + dB 4 + dB 5 5 , dB x + dB x − 1 + dB x − 2 + dB x − 3 + dB x − 4 5 , wherein dB 1 + dB 2 + dB 3 + dB 4 + dB 5 5 denotes an average value of noise peaks of the key bearing pin during first five times of lowering in N times of lifting of a working device of the engineering machine, and dB x + dB x − 1 + dB x − 2 + dB x − 3 + dB x − 4 5 denotes an average value of noise peaks of the key bearing pin during last five times of lowering in the N times of lifting of the working device of the engineering machine. injecting (S200) the grease onto a key bearing pin of an engineering machine and causing the engineering machine to operate without load; causing (S210) the engineering machine to operate under a load of 10% to 150% rated load at least once; recording (S220) whether an abnormal noise occurs during the effective operation of the key bearing pin under different loads, and determining a calculated noise peak generated under a corresponding load; viewing and analyzing a wear condition of a surface of the key bearing pin, and a noise peak condition of the key bearing pin; and issuing (S230) a whole-engineering-machine-based evaluation report of the extreme pressure and antiwear properties of the grease according to the wear condition and the noise peak condition, wherein the engineering machine is caused to operate once under the load of 10% to 150% rated load for 0.5 min to 100 h, and the calculated noise peak generated under the corresponding load is determined according to a following formula: Max dB 1 + dB 2 + dB 3 + dB 4 + dB 5 5 , dB x + dB x − 1 + dB x − 2 + dB x − 3 + dB x − 4 5 , wherein dB 1 + dB 2 + dB 3 + dB 4 + dB 5 5 denotes an average value of noise peaks of the key bearing pin during first five times of lowering in N times of lifting of a working device of the engineering machine, and dB x + dB x − 1 + dB x − 2 + dB x − 3 + dB x − 4 5 denotes an average value of noise peaks of the key bearing pin during last five times of lowering in the N times of lifting of the working device of the engineering machine. <EOS>
