  • Patent number: 11921090
    Abstract: A whole-vehicle-based method for evaluating extreme pressure and antiwear properties of grease includes injecting the grease onto a key bearing pin and causing the engineering machine to operate without load is disclosed. The method includes causing the engineering machine to operate under a load of 10% to 150% rated load at least once, viewing and analyzing a wear condition of a surface of the bearing pin, and issuing a whole-vehicle-based evaluation report of extreme pressure and antiwear properties of grease. The engineering machine is caused to operate once under a load of 10% to 150% rated load for 0.5 min to 100 h.

  • Patent number: 11518953
    Abstract: A lithium-based grease and the preparation method thereof are provided. The raw materials for preparing the lithium-based grease include in parts by weight: 75-88 parts of base oil, 0.5-2.5 parts of antiwear agent, 0.1-1.5 parts of antirust agent, 0.1-1.5 parts of antioxidant, 5-25 parts of lubricant, 5-15 parts of thickening agent, and 0.6-2.0 parts of saponifying agent. The raw materials also include hydroxyl compound-containing modified graphene containing quaternary ammonium salt or aromatic ring. The grease has good colloid stability and mechanical stability, can greatly improve the antiwear property. More than that, the grease has excellent oxidation resistance, and can significantly shorten the reaction time of the saponification, reduce the reaction temperature of the saponification.

  • Patent number: 11332688
    Abstract: The present disclosure relates to an anti-wear, anti-friction and stably-dispersed lubricating oil or grease, and the anti-wear, anti-friction and stably-dispersed lubricating oil or grease includes a main component of a lubricating oil or grease and a long carbon chain-grafted sulfonated graphene, the preparation method of which includes mixing a main component of a lubricating oil or grease with a long carbon chain-grafted sulfonated graphene, stirring and dispersing the mixture to obtain the product. The lubricating oil or grease in the present disclosure can significantly improve the long-term dispersion stability and dispersion stability in a complex environment by adding a long carbon chain-grafted sulfonated graphene in the main component, and at the same time can significantly improve the friction coefficient, which can significantly improve the anti-wear and anti-friction properties of the lubricating oil or grease, reduce the diameter of wear scars, and reduce the wear of copper and iron.

  • Publication number: 20200080279
    Abstract: The disclosure relates to a loader working device for solving the problem of arranging the parts used in a vertical lifting mechanism of an existing loader. The loader working device comprises an accessory, an accessory overturning mechanism, and an accessory lifting mechanism including a movable arm, a movable arm oil cylinder, a front link rod and a rear link rod. The accessory lifting mechanism does not cause the accessory to interfere with a rocker arm and a front axle package of the loader working device. A connecting and mounting point of the movable arm and the accessory can be moved backwardly, thus improving a digging force and a tilting load at a low position of the loader working device.
