The electric tool is an electromagnetic rotary or reciprocating small-capacity motor, which is a portable or mobile production tool that drives the working device through a transmission mechanism. Electric tools have the characteristics of convenient carrying, simple operation, diverse functions, safety and reliability, etc., which greatly reduce labor intensity, improve work efficiency, and realize manual mechanization. Electric tool greases are widely used in electric drills, hammers, grinders, reciprocating saws, cutting machines, grinders and other electric tools, such as hammer gears or cylinders, hammer drill gears, related gears, screws, etc.
Although the electric tools are small, their gears are high-speed, high-impact load, and life-span requirements, and there are many types of electric tools, the lubrication conditions are very different, and the grease is very strict. Power tool grease contains friction modifiers, which can reduce temperature rise and wear and extend service life. It is also required to maintain proper hardness and plasticity at high temperatures and not easy to lose. Under high load and shock load conditions, the grease is firmly attached to the metal surface to protect the metal from wear and corrosion. At the same time, it has a high sealing performance, high vibration and noise reduction effect, and a wide temperature range.
